I'm back with a follow-up question, this time about the DC side.
I'm seeing my DC voltage drop to 1 or 2 volts when I've hooked up both the Victron inverter/charger and the DC loads, with all AC wiring completely disconnected. Specifically, positive terminal of battery has one wire going to the inverter/charger positive and one wire going to the positive bus bar, while similarly the negative terminal of the battery has one wire to the inverter/charger negative and one wire to the negative bus bar. Neither the inverter/charger nor the DC loads function when both are connected, since 1 to 2 volts is too low.
Battery is fully charged. I see 13V when I disconnect the inverter/charger and only connect the DC loads (e.g. lights). Likewise, I see 13V when I disconnect the DC loads and only connect the inverter/charger. But when BOTH the DC loads and inverter/charger are connected, the voltage across the positive and negative sides drops to 1 to 2 volts.
Any ideas what's wrong?
I'm thinking it's related the inverter being grounded to chassis and the negative bus bar for the DC loads also being grounded to chassis. Note I have not yet hooked up any AC wiring to the inverter/charger, so the issue must be contained on the DC side.
Again, would appreciate if others with more experience could chime in.
