Re: need help with generator
Welcome to the forum.
You say series/parallel - as per Page 27 in the manual?
First inverter designated as "master" and second as "slave" (HUB ports 1 and 2 respectively). First inverter using black AC line for input and output (and autotransformer) and second using red AC line.
Now, without the generator connected the two inverters function off batteries and supply 240 VAC up to 2800 Watts?
Or is the master inverter only functioning with the slave never turning on?
Next, check the output lines from the generator. That model does not have a neutral-ground bond built in. This bond should only occur at the final AC out from the transformer, feeding the service panel.
If the gen wiring is disconnected at the gen does it work? Or only if disconnected at the inverter inputs?
It sounds as though the generator wiring is picking up AC hot from one inverter side and feeding it into the other. Try disconnecting the autotransformer and seeing if the problem persists (no loads, no generator running - just wiring).
