    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!

    Nice detail!

    I am new and not good with electrics, but I do intend to follow some of the tutorials here and build a solar generator! The wisdom on this site is incredible, and I appreciate the sense of community, and the support people offer each other.

    Thank you!
