Testing Powerjack 8000 watt under load (1500 electric heater)

I found that taking the gen off eco mode my generator would also stabilize the batt voltage but charging of mains power it's completely stable.

Shouldn't the neutral wire be in the middle position (N) for the input. You have red and black (both hot) in the L and N position.

WHAT SIZE GLASS FUSE DOES IT TAKE ?

I think your readings from your multimeter are off because you are clamping more than one leg at a time. Try clamping just the black or white and see what your readings are. I have the exact inverter and wish to have it run a load panel for a couple of circuits but I am unsure which input I should use for the incoming 220 from the house main box. I assume the black plastic covered 220 port at top is for the 220 split phase output into the new load panel. Please confirm this for me. I can be reached here at [email protected]. Thanks!! Anthony
