I'm Going To Load Test My "8000" AMG Inverter Tomorrow.

[RobertM]

I jumpered the inverter for maximum 115 power, and I wired a 115V receptacle for L1 N1 and L2 N2 and will try to slowly run both legs up to 15A each, using heaters. Will use my AC clamp meter to measure amps, and see what happens. I have a couple 115V electric motors, as well, but that will be later, and harder for the inverter.

If the inverter is "jumpered for maximum 115 power", then the output is not split phase.  It's single-phase 115.

Yes, I'm going to test how many amps I can produce at 115V. I have 175 AH  at 24V of batteries. If I could get 15A from both L1 and L2 simultaneously I will be really pleased. I probably used "legs" incorrectly. I mean both circuits.

A successful test. Using resistive loads (heater and heat gun) on both the L1 and L2, I ran them full out and each drew 11.5A @ 115V. Factoring in the efficiency of the inverter, that's over 3000 W. 

Next, I connected an inductive load, a 1/2hp 7.3A 115V motor to the L1 circuit. It started, but ran for just a few seconds. The inverter shut down, with no sound or red light. The green light remained on.

Then I restarted the inverter, connected a small load (the heater fan only) to the L2 and started the motor connected to the L1. It ran perfectly for over a minute.

I also added  50uF chokes to the L1 and L2.
