I’d like to offer my sincerest thanks to Mark for inspiration to get me going on my build. There are other persons sharing their ideas on the internet, but this was a significant help. Thanks, Mark!

Obviously, there are a thousand ways to skin this cat. My Solar Generator build is my best effort for a large, pure sine wave generator to help carry us into a grid-down situation. It could be used for camping and picnic’ing, but this generator is likely destined to remain a part of my survival kit, mostly. Normally, it will be charged by solar panels on my roof. Alternately, it has an inlet for 120VAC grid-power for the standard charger.

Some considerations I baked into the design:

– 3000 Watts of Pure Sine-Wave Inverter
– 250AH worth of batteries
– Enough Solar Panels to recharge the setup in a reasonable time
– Gel Batteries
– External Studs to either gang additional batteries or jumpstart a vehicle
– An MPTT Solar Controller
– A high end charger to protect my battery investment
– Large DC Cabling to allow the inverter to perform
– Plenty of metering to keep tabs on the generator’s health
– Semi-Portable given its 175+lb weight!
– Not Weatherproof, but at least mildly weather resistant
– A big DC disconnect to keep the bulk of the power isolated
– DC outlets to provide for LED lighting, small battery chargers, radios, and such

I have attached some photos, a schematic and a parts list.

Perhaps my build will carry on the inspiration to others.

Best of Luck to all the other ModernSurvivalists out there!
