I have an issue with current flow on my ground wire.
My main panel has the neutral bonded (Sub panel does not).
The LV6548 inverters - AC Line IN is not bonded, AC Line OUT IS bonded internally. (Everything looks good here to me)
What I have found...
While running sub panel circuits without going through the inverters (Main panel to sub panel through the manual transfer switch) everything is fine.
While running sub panel circuits through the inverter while on battery backup (Power outage simulation) everything is fine.
While running sub panel circuits through the inverter but in normal (Power on main panel is on and routed through the AC input on the inverters by way of the manual transfer switch) I loose bonding and I have current flow through the ground. This is a bit baffling here. The inverter should only be acting as a switch and the bonding from the main panel should not be affected just by being routed through the inverters. When the inverters transfer over to backup mode they have an internal bond and all is well again.
Has anyone with the LV6548 inverters experienced this or checked for current at your main panel on your ground in a similar setup as mine?
