Lucid-grower Posted March 18, 2020 Share Posted March 18, 2020 Hello. I am just considering the Doomsday scenario, and I am curious if anyone has done the math somewhere, on how to get off the grid? For power: What are the options? Wind + Solar + Battery? For water: I already get my water from a borehole, I would just need to power it separately. So has anyone done the math on getting off the grid, perhaps with links and suggestions for products? (I'm not retreating into post-apocalypse mentality, I've always wanted to do this anyway, PS: Anyone seen the episode of South Africa's orania on Netflix's Dark Tourist?) Thanks, stay safe out there.

Prom Posted March 18, 2020 Share Posted March 18, 2020 You find solar calculators all over the place. It depends how much you consume.. same counts for the borehole pump. If you want to drink the water, run it though a filter. Just calculate all the wattage from the gear you want to run over a 24 hour cycle.. and then check with a company (for example: https://www.exsolar.co.za/) how much the system would cost. I suggest to go with a hybrid system and not a pure off-grid setup. 2 Quote Link to comment Share on other sites More sharing options...
420sake Posted April 28, 2020 Share Posted April 28, 2020 Done it bru. Growing my first batch of plants under solar lights run by an Atom450 generator in our nursery, fed by spring water delivered from a solar pump. Basically to stretch the day beyond the 12/12 seasonal limit. Our 3rd gen plants going into bloom now since the start of the season. Our house runs off a Blue Nova 24KWhr lithium battery. Still charging with Eskom, but a solar filed is in planning. Like "what loadshed?" 1 Quote Link to comment Share on other sites More sharing options...

Bro, I've done some math on it if you're interested. Even thought up a breaker system to operate 24hr appliances separate from entertainment & lights, etc all with fused breakers and with the overall circuit grounded. It was a while back and for future projects but I wouldn't mind trying to go through some of the math again. I'll need to get updated prices though Solar + battery is the best option right now I feel.
