Josh Hobson of Oklahoma City DIYed a 5000W off-grid energy storage system with a PowMr 5kW inverter, with future plans for integrating 4500W of solar capacity to create a comprehensive portable energy solution.

Key components include a PowMr 5000W all-in-one inverter, a 51.2V server rack battery on a dolly for mobility, a 200amp double pull breaker between the battery and inverter, 10 AWG 15amp extension cord for AC input, 8 AWG THHN wire for power distribution, and a 50-amp main shut-off with 16-amp and 20-amp breakers for outlets.
