If you’re looking for a safe, reliable way to build your own massive DIY offgrid solar system at a fraction of the cost, you’ve come to the right place. This is a detailed walkthrough of the planning and installation of our 7,200W 28kWH 5,000W 120V offgrid solar system that powers our entire homestead. By piecing together our own system from multiple components we were able to save thousands of dollars. Powered by SanTan Solar Panels, REPT LiFePO4 Batteries, REC BMS, @VictronEnergyBV Inverters, Charge Controllers & Color Control GX, and @IronRidgeSolar rack mounting.
