3000W inverter low output voltage

Kzneft · Jun 4, 2022

I have a PowrTech PS1004 (3000w) inverter. On our last trip I was wondering why the microwave would not run well. Today I unplugged everything from the inverter and checked the output voltage, and I am only getting 89 to 90 volts output. The inverter is only a foot from my lithium batteries, getting 14 volts to the terminals on the inverter, and reading voltage directly off one of the inverter output plugs. Anyone have any ideas? Did GoWise purchase power TechOn ? Can't even find the GoWise website or Power TechOn website. Are there switches inside to adjust?

If it worked okay before, but not now I would check the cables. It sounds like it may be on it's way out though. My cheap Relaible inverter puts out 123 volts at the plugs. It's 3000/6000 also. I didn't use the cheap double cables that came with it though. I have 2/0 AWG welding cable from the batteries. I'm assuming you have it fused from the batteries. It may be a partially bad fuse connection.
