Hi David,
I own and tested the 48V version Resu10, not the 10H that you have. On
the one I have, the battery needs a heartbeat signal to operate.
Without that signal from the inverter or a device that talks to LG
battery the contactor will open and shut down the battery.
This was a pretty early lithium offering and has proven to be very
undesirable. We destroyed 2 of the Resu 10's with XW charge currents.
Not sure if your plan is safe. Maybe the guy's here will know more. I
would hold off until. Good Luck
