Some of us in the crypto space looking at 'Off Grid' living wonder:
Is it possible to build an inexpensive crypto settlement node operating with off grid power?
Absolutely!
Running a crypto PoS or lightweight PoW settlement node powered by batteries serving as the 'prime mover' of electricity to your off-grid home or outback location is possible BUT, and requires a bit of planning to integrate three different battery trickle chargers.
The Good news is there are plenty of lego pieces for charging, energy storage and crypto settlement nodes.
Personally I have been working on one of those three battery Trickle chargers, TwindPower to improve capacity factor and hit a price where no taxpayer subisidy is required for a DIY kit. The TWindPower design has been an on and off effort of mine for a few years and now finally, I am now ready to share the how part in the context of off-grid crypto settlement power.
What about Internet Connectivity for my off-grid crypto settlement node?
Having experienced first hand XplorNET service for line of sight in the GWN via this Canada Wide rural WISP Wireless Internet Service Provider I can say there is no problem going off-grid to do crypto node settlement. The WIPS will outfit your off-grid abode with a WI-MAX home roof mount mini dish wireless connect 'line of sight', to the main Tower mount dish, as far as 15 miles away typically. Do expect slower speeds during rain/snow and heavy fog, knowing your network WIP access is running TCP/IP over the WAN, you will stay connected. The upload and download WISP speeds are more than adequate for running a settlement node or crypto , completely off-grid, provided the node is POS,or lightweight PoW(IOTA).
The other two Trickle Chargers for Off-Grid Power of your Crypto Settlement Node: Solar and Diesel or Gas)maybe even NG)
Reality says we will need both 2KW of solar and last resort diesel or gas generation for trickle charging for those unpredictable still (no wind) and cloud (no sun) days.
So powreing your off-grid crypto settlement node is really all about properly integrating this Trifecta of Wind+Solar+Last Resort diesel/gas into an effective reliable trickle charge system for your battery array. Your battery array of cheap 12Volt Lead Gel Acid Batteries should have a kiloWatt hour depth which is deep enough measured in kilowatt hours of energy storage to run all your essential outback abode appliances, lights and heating as well as your crypot settlement node to survive at least 5 days of complete wind and solar zero trickle charge days, typical of most inland sites. Coastal or BIG lake side sites maybe 2-3 days of energy storage depth is needed.
That said
Progress on my side has been slow on the wind powered trickle charger part of this design, given the last year's economic upheaval. So I am a bit behind on gettin TWINDPower off-grid charging system for batteries readied into to DIY kit form to support staking and micro PoW settlement nodes.
(I don't do mining)
This is a long post, mainly for my own records and reference, so if you are busy now, please move on and return to this post when you have quality reading time of about 30 minutes to digest it all properly. :)
Bird's Eye Perspective of the TwindReiver 4kW NP Off-Grid Battery Charger for Crypto Settlement Node Project
Off Grid Realities of Powering a Crypto Settlement Node.
If the power goes out, its still possible to stay connected because these days,mobile towers must stay up for 72 hours now in Canada and in the USA (mainly diesel generator backups) as required by law, changes prompted for safety reasons after the 2004 Katrina disaster in New Orleans, where many people died because mobile service collapsed after 24 hours. The same goes for WISP provider infrastructure on North America.
'Crypto Stakers' looking to run a settlement node off-grid also need to stay up and running all the time, to ensure their reputation grows and their chances per epoch are higher to gain some of the settlement reward paid in crypto.
For those Stakers running home nodes which support staking settlement , this up-time is a REAL challenge in places where power is sketchy like California for instance land of the unpredictable rolling brown outs and scheduled blackouts and, home of the highest paid Caterpillar Diesel Home Backup Power sales people. (California's frequency of brownouts and rolling scheduled and unscheduled blackouts, due to long standing goofy/compromised/captured government management practice make Caterpillar a somewhat stable stock pick imo, even it is FIAT.)
So a Home Staker settlement node operation there is hence the need for a 'pony panel' in the house, directing power to the home office at least running the nodes primarily from the batteries, most all the time. This nice thing about #IOTA is there is no staking required, more importantly their Smart Contract DevNet 2.0 is finally up and running ready to run your EVM SCs in Solidity, Rust/WASM and tightGO on level 2 side chains giving each SC per shard 25 TPS with inter-SC settlement handled Level 2 to Level 2 over the existing Level 1 Distributed Public LEDGER of IOTA called the Tangle. So IOTA is getting close to being a production SC network with huge TPS scale, imo the ETA for IOTA production release is likely calendar year 2Q 2022.
This means a home powered staking settlement node, whatever your fancy, need to have the 'prime mover' batteries reliably charged as cheaply as possible, which means using: unreliable wind first; unreliable solar second and, last resort; using somewhat reliable public grid and/or most always reliable ICE Internal combustion engines (natural gas best, diesel worst, gas/petrol in between) in a sequence of trickle charging keeping your batteries powering your staking nodes reliably, with best durability, all the time, so your Staker Settlement Node reputation is always at the top of the list, every settlement epoch, which these days can be anywhere from a few seconds to worst case 10 minutes.
Not Much power is required for your node to participate as part of settlement quorum during the Epoch in the PoS 'staking' world its all about how much you Stake to get that right to earn a reward for enabling settlement of transactions. In the hybrid PoW of IOTA, for either Level 2 SC or Level 1 Inter SC and straight crypto settlement power requirements of the CPU. Such lean power requirements means the off-grid site can, with proper planning get away with using two out of the three trickle chargers available, with a diesel/gas(NG possibly) always being a mandatory 'trickle charge of last resort" requirement.
Wind powered battery trickle charger TwindPower (see below) sports dual rotors running counter clockwise sharing the same guyed mast, with each Starwind5 rotor having their own low cost 2kW permanent magnet generator wired to their own 2kW input charger controller wired to separate battery banks 50% deep enough to support your still and cloudy day budget.

Using Small/Micro Wind Powered Generators as Trickle Chargers for Staking Node Operation Batteries:
For Micro Wind- It's all about 'Capacity Factor' matched to the right site at the right height
For small wind to work as a trickle charger for your Staking Settlement Node (and also support your atomic swaps Party to 2 Party without central crypto exchanges), charging batteries without a subsidy from a government (to compete effectively with ICE diesel or gas powered electricity generator tech) in designing micro wind Capacity Factor, which is the Name Plate "NP" power percent of power on average through the year is tricky.
Capacity Factor is always ultimately delivered by the charging system setup to charge the battery, so there are power transfer losses along the way, typical 8-15%.
MicroWind Price/Performance(Capacity Factor): Always less than Big Wind?
In the case of Micro Wind, to be cost effective it needs to be equivalent to BIG Wind, which is now largely un-subsidized in most US states, where such big 3MW turbines regularly operate around 45% if properly sited, and often in good wind regimes are over 50%, enough for the wind farm investor to see a rapid return on their investment in about 5 to 7 years from equipment designed to last 20 years, funded 60/40 or 70/30 debt versus equity.
Upfront current state of the art BIG Wind is about 3X more efficient generating power in real field production of power than is Solar, but BIG Wind is also at least 2.5X more expensive given current legacy micro wind offers. Both have similar disposal costs.
To set a micro wind capacity factor design goal baseline to shoot for, let's look at BIG wind as it is well understood and has proven numbers about acquisition and operation costs and, warranty as well as regular annual maintenance charges which look like this:
A 3 MegaWatt '3MW' Turbine Installed Levelled Cost of Energy 'LCOE' https://en.wikipedia.org/wiki/Levelized_cost_of_energy has currently an "installed and activated" cost of about US $ 1.30/Watt, best case. (CN yarps about 0.80/Watt but it's the CCP Regime)
In North America BIG Wind 'Regular(annual) Maintenance' will end up being 6.5% per year of the BIG Wind Capital Acquisition Price Charged for the Turbine Installed and Activated (Turnkey pricing).
Meaning a 3 MW BIG WIND Turbine can be acquired, installed and activated for a cool US $ 3.9 Million so Not bad.
That said though Big Wind typically has NO battery storage, so it's a use it(sell the powet) or lose it(dont sell the power or, sel;l the power under cost to adjacent monetized power markets) investment proposition (forcing a subsidy request up front to sell power at higher rates to the public grid), which is why Big Wind is so heavily and indirectly subsidised by the rate payer. (And why those in the oil and gas (also a hidden subsidy space) space are the first and often very quick to point out Big Wind really doesn't work)
Unscheduled BIG Wind maintenance (replacing a blade hit by lightning for instance) is charged 'a la carte' at current market rates for parts and labour and supporting installation equipment rental, with 'time to fix' being the big problem, as a double lift crane from Germany is usually rented with a backlog of jobs stretching months. So the lost power producing time is the real cost of a systemic failure like losing a blade, where the blade replacement is in the spare parts warehouse, but there is no way to install it.
So really we are talking about a 15 year Cost of 3 MW Wind Turbines being more like US $7.5 Million where maintenance on going accounts for 45% of the total life cycle cost, adding in my guess/estimate of US $500K cost to remove and remediate the site and dispose of(bury) the non-recyclable turbine blades. (Usually buried these days in Wyoming for some unknown reason).
So really the BIG Wind vendor advertised Cost/Watt versus lifetime reality understates the total price installed when considering useful life by 50%.
TK Observation- Yes China is cheaper at about US $ 0.90/Watt installed but only because the CCP employ 'near slave labour' and also employ tricky accounting practices in CN finance circles to engineer the returns anyway they like.
Typical Charger Controller used with Wind and Solar Trickle Chargers for 12V Lead Gel Acid Batteries priced in CDN $
MicroWind under the Microscope- for use as one 'unreliable' trickle charging of batteries power a Staking Settlement Node
Solar being the other unreliable trickle charge source, with cloud days and shade et al, means we should not forget to downgrade our real field powr generation expectations given the current solar dimming going on by Captain Chemtrails and the Weather Modification Gang driving actual solar panel efficiency into the toilet below 10%.
With Micro Wind, down days are very much micro-climate site specific, but count on at least no usable Wind 15% of the time even if well sited inland..
Therefore You will need 2KW of Solar on a manual pivoting or auto-tracking mount to compliment the trickle charging of the TwindReiver 4kW NP system if you site is marginal, again backed up with trickle charge of last resort powered by diesel or gas.
Delta 1800Watt Diesel, Compact, pretty, not very expensive at CDN $1469.00
Last Resort Trickle Chargers: Gas or Diesel
Diesel and Gas Generators are cheap, so getting a 3-5KW for the whole cottage or country home is usually more than enough a sizeable fuel tank, large enough to sustain the generator running at 50% to extend life and economize on trickle charging producing 1.5kW to 2.5kW power to the battery charge controller, tied in to respond to on/off signalling of the auto-start mechanism.
MicroWind Economic Realities
What is clear is Small/Micro wind under 10kW for the latter today is double the Cost/Watt these days of Big Wind, sitting at around US $3.20/Watt.
Recently for horizontal axis wind turbines so called HAWTs, new designs have recenly emerged which accelerate wind speeds with cowlings close to the tip of the rotor blade to boost annual protection performance by 15-30% over what is typically a capacity factor, if properly sited at the right height somewhere around 25% to 30% Capacity Factor of micro wind 'Nameplate. Meaning (before acceleration) we have the following from micro wind
Let's use 2 kiloWatt Nameplate costing US$3.20 watt
Installed and activated this 2kW Wind powered Generator for a propeller style system such as Bergey should see the tower cost being 45% of the total cost, leaving 55% for the Wind Powered Generator
US $6.40 * 1000 = US $6,400 for the complete installation
55% Wind Powered Generator Cost installed and activated = US $ 3520.00
45% Tower Cost installed and activated = US $2880.00
( site mount advice 40 ft High large Telephone Pole Height, 200 yards away from any nearby canopy of same height)
This means the Wind Powered Charger needs to be made on US soil for US$ 1760, with a markup of 2 on the cost to reach the discounted price to the end user, which frankly also wants a discount of at least 10% making the US MSRP likely around US$3895.00, before end user discount.
The markup of 2 rationale is pretty typical for a manufacturer to receive a 20% return before taxes on capital employed for low to medium annual volume goods production and sale.
OK standing back and taking a look at a plain vanilla Wind Powered Charged of 2kW Nameplate with a capacity factor to be kind, of say 30% means on average, the Staker Settlement Node Operator will receive 600Watts/hr on average over the course of the year to reliably charge up the node.
OK what about the cost of Deep cycle draw (to 40%- 50% depth of Charge) Lead Gel Acid batteries which are cheap at about US $200.00 per kilowatt hour 'kwhr' with cycles now about 4000-5000, with the price of the charge controller thrown in. The big question of battery banks size is how many hours of energy storage do I need to seurvive the potential brownout or blackout condition in my neighbourhood?
Let's say 4 days is good enough for 99% of all blackout conditions in my area to be good enough to preserve and grow my Staking Settlement Node's reputation.
4 Days * 24 hours at 1000Watts per hour will cover my Staking node's primar mover battery banks charging needs.
9600hrs or 9.6KiloWatthours energy storage depth, so let's make it 10 kilowatthours or
10kwhr * US $200kwhr = US $2000.00 for the Batteries needed (10 of them at 1kwhr depth) top get 10kwhrs of Staker Node energy storage.
The Mythical Tesla PowerWall Price/Performance- Thank you Nevada Ratepayers
Stepping back, Tesla car enthusiasts will say "hey wait a minute, Tesla is only charging me US $160 per kwhr, and that is lithium ion which I can draw down to 90% of the labelled kwhr capacity reliable with number of full draw down cycles up to 6000"
lol.. don't try to convince a Tesla car owner otherwise.
That said, Tesla does have a cost advantage via their 10 year ZERO tax break they extorted out of the state of Nevada at the expense of the rate payers, so thank you Nevadans. (And thank you near slave labor in CN for digging up that Lithium clay, with your bare hands, not.)
Looking at the Tesla Powerwall Spec:
- Energy Capacity 13.5 kWh
100% depth of discharge
90% round trip efficiency
- 7kW peak / 5kW continuous
Seamless backup transition
Pure sine wave output
We need to increase the cost and a capacity of the Lead Acid Gel battery solution to US $ 2700. Add in a Midnight Controller from Outback for US 600.00 installed (US $150 labor) and at US $3300.00 we are now comparing MacIntosh apples with Gala Apples.
The MSRP Delta in US prices between Tesla and Led Acid Gel is really US $2200 as PowerWall costs MSRP US$5500 for 13.5Kwhrs
So Tesla in effect is 66% more expensive than LED Acid Gel, so what gives? Why the big price differential as why is Tesla (lithium ion) so expensive?
Well keep in mind you can draw down Tesla Powerwall to 90% of Advertised charge depth of 13.5kwhr and still deliver 5kW continuous to the controller connected device drawing on the power (Pony Panel connecting your Equipment rack supplying power to your Staking Settlement Node)
Versus only 45% on average with Gel(matt) Lead Acid. Both have similar 'complete draw-down' cycle counts managed efficiently by each charge controller type.
So in the end, Gel(matt) Lead Acid looks to have a slight advantage, at the moment as it applies to ROI and LCOE, so you might be saving $1000.00 on going with GEL Acid in reality.
But wait! Do I really need 5 Kilowatt continuous power output to power one Staking Settlement Node?
Nope. You only need 600W continuous at most for the Staking Settlement Node operation, IF you are running TWO nodes to geive yourself a better chance of winning a reward for handling settlement ( ie- SOLANA) , given most 1U Chassis with SSDs will only really need about 260Watts max.
So PowerWall is overkill for the Staking Settlement Node energy storage application and Mighty Max rules courtesy of WalMart, even in Canada eh.
Lead Gel Acid Rules, Lithium drools- Picking Energy Storage Batteries on a Budget = 12V Lead Gel Acid Batteries
Now back to the Wind Powered Battery Trickle Charger.
And the Solar Panels.
And the ICE Backup.
And the Grid Connect.
Really?
Do I really need all this trickle charging to keep my Staking Settlement Node up and running all the time?
Yeah, one does need some mix of the above and,
one also needs to power a switch over to 3/4/5G Cellphone Tower transmission, because of the power goes down in the home, one's fixed Internet is likely to fail if not wired up properly to WI-MAX WISP services, unless the WISP provider have backup at the Fiber Optical Cable Head-end supporting Fiber connections to their backbone or the Fixed Fibre to the Curb FFTC Internet Service Provider does same to keep one's apartment suite/condo Up-time, "all the time". (for which one pays more money, monthly to the Cable guys).
So having a cheap burner mobile 3/4/5G phone able to act as a mobile wireless hub wired to your Node via USB 3.0 (power and data at higher speed), equiiped with a pay as you play Sim Card MVNO Mobile Virtual Network Operator Service, configured in Data only mode, makes a lot of sense, should the WISP connection die.
Let's face it,
if you are running your own 'outback' off-grid home office and a Staking Settlement Node to have the latter earn 'passive income' rewards on the side, even with LED lights and a cheap 500Watt space heater, you are going to need to carefully budget your home+node combo for no more than 2.5 Kilowatt power output so you drain your energy storage slowly, split over your AMP needs, continuous. So let's look at your Amp needs per device
What's the Draw, Power Draw that is.. for a Crypto Settlement Node
Multipurpose General Use Server and Staking Settlement Node - 760Watts Peak running at 380Watts on Average.
2.5 Amps draw Staking Node at Peak with 2X 360Watt dual power supplies at peak, max, so 620Watt Peak state condition
10 Core AMD/Intel64, 32GigaBytes of Memory,
Containerised KVM (or Virtualbox) Hypervisor with 6 Virtual Machines,
4 Gigabyes of RAM for each Virtual Machine, 2 Cores each,
Each VM running a Guest OS copy of Windows11 or MS 2022 Server, or Ubuntu 20.4 Linux (best choice) with containerd running in each VM at minimum to let you easily update your containerised Staking Settlement node software via Vagrant (HashiCorp Github) or something similar (like Docker and Rancher combo)
ETH 2.0 Staking RewardsInternet Access 24*7 Protection for Staking Settlement Node Operation- 100 watts(Wireless) to 250Watts(Fixed)
Wireless 4G - Samsung S9 Mobile or Apple iPhone9 running in data only Gateway Mode with unlimited data transfer via a cheaper MVNO offer(Wireless WAN connection over configured public static TCP/IP address with ) + Ethernet 1Gigabit 4 port switch hub .1 AMP
A WISP connected 50 Megabit Bidirectional Power Backed up Internet Cable Modem and Router with static public IP address for Staking Settlement Node with 1gigabit 4 port Ethernet Switch Hub (if the cable provide fibre optical cable 'head end' is power blackout protected) under 1 Amp
A Typical Budget of Watt consumption of the 'OutBack' home+Node might look like this:
Lights - 100 watts (LED only) - 1 AMP
Heating/Cooling - 500 Watts (mini space heater/cooler for 10 foot by 10 foot home office ) 1.5Amp
Total Watt requirements continuous worst case at peak = 1610 Watts
with room to spare on Pony Panel Power Out max draw of 5 Amps continuous should one's home, apartment or condo blackout.
n.b- wireless Internet access is one's only option usually in an apartment or condo home office setup
OK so one needs really 2kW sustained continuous power output from the Pony Panel worst case to power the home office and the Staking Settlement Node in the case of Power Blackout with a peak draw of 5 AMPs.
Wind and Solar, a likely Energy Storage TRICKLE Charge combination?
Maybe... as long as you add Diesel or Gas as Last Resort
Meaning at 600 Watts average trickle charge from Bergey 2kW NP or similar wind powered AC output charger, you would need to supplment such unreliable charging with 2K or roughly 6 to 8 of Fixed Solar Panels on your roof top of 360 or 240 Watt peak output with 15% efficiency ratings.
Now depending on where you live, solar power peak output will be affected by shade, and dimming due to clouds and lately chem trails, so downgrade your peak power expectations by at least 20% for solar, and make sure to keep your panels clean regularly, especially if your home is located in a dusty large city or dense suburban environment. Meaning your 'dimmed' real life solar efficiency in real life is more like 11 to 12% best case.
Small/Micro Wind efficiencies are stated by vendor in terms of Coefficient of Power 'cP', which is a measurement of the wind turbine's ability to extract the maximum kinetic energy from the wind before any additional looses of power are incurred (bearing resistance, cable resistance) is limited in the properly sense (horizontal) by Betz Law (only .59 of the wind flow energy available can actually be extracted by this type of turbine)
A Good small wind turbine like Bergey advertises cP of 0.42, not bad, which yields a capacty rating for 2kW of 30%, our 600Watt hourly average expected for 1 year from a properly sited generator placed at the right relative height versus nearby (no closer than 200 yards) local canopy disturbances at the same mount height) Canopy tops being tops of buildings or tree tops in most cases, but could also be hill tops.
Suffice it to say with today's legacy micro wind powered chargers equipped by Bergey or similar, one needs ICE Backup of 3 KiloWatts Nameplate running on natural gas home hook up or with regularly stirred tank diesel, to really back it work, where the cost of fuel is also a big price consideration (50% of the cost for running hours needed over the useful life of the system, is a good number to use in figuring out total ICE costs)
Solar Only- 10 panels at 2KW to "Prop and Go"?
5 Kits at US $ 1,198.00 for the online Amazon Shopper without the patience to shop for a good deal...
Sad but most likely the right solution for urban and most suburbanites 10X 200W Panels in the back yard
Solar Powering their Crypto Node off-grid trickle charging of Energy Storage
Let's face it, wind is not possible in many locations suburban or urban, so Solar will be the defecto way to set up trickle charging. If fixed solar panels are your only option you will need to install 20% more panel Name Plate "NP" capacity versus a 4KW or 5kW NP system which supports sun tracking. That means effectively 5kW to 6kW is required, where panels these days are at about US $ 0.66/Watt
So 5KW installed at about US $1.00/Watt means the installation/activated with charge controller will cost about US $5,000.00 which means at this price point there really aren't any subsidies anymore worth pursuing for Solar from the state or province authorities because it is now cost competitive, given the dumping going on from China . (That could chance of course should the tarriffs go up again against China to repatriate jobs to the USA)
So in a Solar only situation you still need ICE as backup and Pony Panel needs to be setup to receive charge controller signalling measuring charge depths to auto switch to the ICE, should solar energy not be reliably available given current and predicated battery levels versus forcasted consumption in the home office (really likely going up and down between 1200 Watts and 1680 Watts during a blackout, partly dependent on how well insulated your home office might be versus weather conditions at the time.)
MicroWind Only- Capacity Factor Needed North of 60% on MicroWind:
Enter TWINDPower (with ICE attached as last resort charging)
If you are out in the open , chances are you have wind, at least above the tree tops, should your open space be heavily wooded.
TWINDPower's new innovation of Curved Flow Acceleration has been coupled with high local angle of attack (climb and dive) airfoils on the TWINDReiver 4kW NP Systems utilizing two Starwind Rotors equipped with easy to assemble sectional Exoblades.
The acceleration wedge portion of the TwindReiver design has a rear facing dual large eddie(lower pressure creation) wake control system and dynamic passive yaw system to maintain consistent low pressured accelerated (Bernoulli effect) flows typical of must airplane wings. The whole combination of TwindPower new features creates a new micro wind industry leading Capacity Factor of at least 60% , good enough to compete with Gas and Diesel power efficiencies, without the pollution, when you have wind.
One TWINDReiver 2 kW NP tower supports the acceleration wedge and two counter rotating Starwind5 Rotors configured to me mounted in the prevailing air flow, usually found at small telephone pole heights of 30 feet or higher, if you have surrounding buildings and tree canopies, you will need at least 50 meters spacing from canopies(tree or roof or hill tops) of the same height. Each rotor is equipped with OTS (off the Shelf) low cost and reliable Permanent Magnet Alternators having a continuous operation rated Name Plate rated at 2kW, with each 'genset' equipped with long distance AC cabling to get from the site to the charge control in the shed with minimum power loss and at the lowest cost of cabling. (Stringing DC cabling is expensive and requires some engineering calculations, so its not typically used.)
TwindPower is Made in North America with all USA and Canada sourced parts and materials and, like I mentioned earlier is designed in Canada to survive and thirve in Canadian winters, blow dirt and generally shitty extreme hot & cold climates.
TWINDReiver 2kW NP was purposely designed to serve the home office, remote office, remote work site for off-grid power delivery where the batteries are always the prime mover of electricity from a pony panel (with circuit breakers) feeding the main panel to feed the nearby sources of power use.
Both TwindREiver 4kW NP DIY kits and ready made systems (without the Mast mount, which are about 50% the cost of the system typically) make it possible for two people to build up and erect a TwindReiver 4kW NP trickle charge power delivery system in a day (Minus the battery charge controller shenanaigans, allow 1/2 day to get that right) with sufficient energy storage to support a reliable Staking Settlement Node, 100% off grid and also run your abode with solar optionaly attached and last resort gas/diesel powered electricity generation always in place. (provided your local mobile provider has their act together.)
TwindPower 4 kiloWatt Name Plate Trickle Charger for OffGrid Battery Energy Storage-
60% Capacity Factor is good for 2+ kilowatts per hour on average over the course of year, properly sited.
Conclusion- MicroWind for Trickle Charging of Batteries Powering Staking Settlement Node in the Home Office?
With a few caveats,
Micro wind only works on its own with a 'last resort' ICE diesel or gas trickle charging integrated via the charge controller (Outback Midnight or similar 2KW units) with TwindPower's TWINDReiver 2KW NP system.
For the record, TwindReiver 2KW NP DIY kit was specifically designed by moi, to do this job.
Otherwise, if you are a suburban dweller with little access to good wind, go get yourself a good companion tracking 4kW solar panel generation system with auto sun tracking coupled with ICE trickle charge backup, especially if you live in the city or dense urban area, provided one has wind access. (It will cost the same price as the expensive per panel Amazon Bluetti deal shown above and be more efficient.)
If you and your home office are out in the open, and have good mobile access with a reliable provider, TWINDPower on its own backed up with ICE powered trickle charging is likely a good option, provided you have consistent Wind and no nearby canopies disturbing the flow, so be sure to research your local weather to find out what the wind rose looks for your site at 10 meters hight if you can, many of the maps are at 30 meters height for the wind speed data, so reduce your power expectations by dividing by 1.7 for every 10 meters down from those 30m number published to match the actual mount height of your TwindReiver 4kW NP system.
Otherwise, TWINDPower coupled with Solar and, an ICE last resort trickle charger is the best bet to keep one's entire home office, and maybe home up and running in any blackout situation, where one can still earn rewards from running Staking Settlement Nodes, provided your Mobile operator has their power backup act working properly in the their greater mobile network, to stay connected to those parts of the world which are not blacked out.
That's all for now, all feedback and ideas welcome,
ETA I expect the WindReiver 4kW NP DIY Kit be ready for Spring 2022 to ship said DIY kits with payment supporting using popular cryptos, so stay tuned on this channel to find out more.
Thanks for dropping by
