Bought this 72 VDC inverter (nomimal voltage) used from an online auction website. I had two 84 VDC batteries from a former Ebike build that I thought would work. After cleaning and inspecting the inverter, I wired it with an 120 VAC lamp. This is a simple test with a very low current draw. Success! The inverter works fine.
Experimenting with different layouts of the inverter, batteries, and some conduit fittings. This is layout position one.

Work-in-progress on the portable power-station for emergency backup power in Albion. I'm using plastic conduit because it's non-conductive and lightweight. I drilled the knockout holes on the junction boxes. Measure twice, cut once. No mistakes. The conduit fittings and tube line up perfectly and are level. Countersunk a pair of 12-24 machine screws inside the junction boxes to hold two Dinkle terminal blocks. I'm using these terminal blocks to merge two 10-awg wire to one 6-awg wire. I'll be wiring two 84 VDC batteries in parallel. Each battery's will be protected by its own 40A DC breaker. The DC breakers are rated for 150 VDC. This cart will be indoors. I'm using conduit to protect the wires since the cart will ultimately be powered from two 84 VDC LiFePO4 batteries.
