My off grid office shed, powered 100% by wind & solar

Tony,you are The best

[@FinlandTony]

Thanks Costel 😁

[@danielnicholls6868]

should build a tiny battery and inverter shed near wind turbine and mount your solar on it. run 220 volts to your big shed. less line loss than the 12 volt long run.

Wow, its very inspiring me, Brother... 👍🇮🇩

[@silverismoney]

Are you from Finland? or Newcastle :) cool video. I want to put wind on my shed but everyone is telling me don't bother it needs to be 15m in the air.

Great vid, thanks.

Can you get a DC to DC power supply for your computers, so you're not doing DC to AC, AC to DC?

[@pompeyexileuk205]

Tony, as it's your work/business office, why don't you have it insulated?

[@FinlandTony]

In winter I'm mostly working in Lapland, so not at this house so much. It's all single pane glass and it's quite drafty too, so insulating it would help somewhat, but it would never be perfect and would still haemorrhage heat in like -10°C.

[@pompeyexileuk205]

@@FinlandTony Blimey, I'm surprised it's single pane glass. I have a friend who has lived in Sweden these past twenty or so years whome I've visited and I thought all buildings with windows in the Nordic countries were triple glazed... Okay, maybe not sheds.

[@FinlandTony]

@@pompeyexileuk205 Yeah, most buildings are. Even my garage has double glazing and insulated garage doors and that stays about 16°C warm even in -25°C. My cottage in Lapland is double-double glazed (two doubled glazed windows on top of one another), so quadruple glazed. But this really is just a fancy shed not really intended (by the manufacturer anyway) for human habitation. It was cheap to buy and cheap to build though, which is what I wanted.

why not grab an MPPT charge controller and hook up the 300 watt panel to your system?

[@ilkkapaavilainen2687]

Sulla on vaikka mitä vehkeitä. Meillä myös paneelit katolla.

[@FinlandTony]

Kuinka monta paneelia sinulla on? Missä olet Suomessa?

[@ilkkapaavilainen2687]

@@FinlandTony asumme Lopella läyliäinen on kylä. 12 paneelia, suunta etelään eikä puita varjostamassa. Paneelit ollu vasta viime syksystä asti joten ei paljon kokemusta vielä.

@@ilkkapaavilainen2687 Ok will do, I will wait a few days then can do a January, February, March review of how much solar I have made.

Very interesting. Have thought about upgrading the batteries to lithium? They’re quite expensive but apparently you can use 100% of the power as opposed to 50% with lead acid. A lot of motorhomers are converting because you can save a bit of weight as well. We’ve got one of those stove fans on the log burner in the living room. I bought it off Amazon for about £20, it’s useless. Does yours make any draft? Ours spins like hell but never seems to create any air movement!? Nice man cave btw.

[@FinlandTony]

I have considered lithium, but yep they are still too expensive atm. I did put one in my motorbike which saved 2kg, but for a big system, it's just not economically viable. These 3 x 100AH leisure batteries were 99 euros each and it amounts to 3.6kWh (granted I can't use all that without damaging the batteries). Even if I halved the AH (because with lithium I could use all of it) it is 420 euros for a 50AH lithium battery, so would cost 1260 euros for 3 x 50AH lithium batteries, giving the same amount of usable storage I have with these leisure batteries. Honestly, I'm just gonna keep adding these lead acids to the system. If I spent 1200 euros on these, I'd have 12 of them amounting to 14.4kWh storage. Soooo much cheaper than lithium it's a no brainer. The stove fan is ok, it just gently moves air around, it's not as powerful as a normal fan. In a medium to large room, I doubt they'd be effective, but in small areas, like a shed, they work well.

Clean that keyboard tho Things dusty Speaking of which gonna need to solve that problem cause dust and computers don't mesh well

[@1981dasimpson]

your are mesuring the watts at the ac side this is not a true reading of power your using due to losses of the inverter you wont to be measuring power into the battery and out of the battery it would be better to be on a higher voltage battery bank say 24 volts as it is more efficent to step the power down and try and run as much as you can on dc loads it is more efficent no not have inverters
