What dictates when/if the EG4 6000 is sending generator or grid power to the charger only vs bypassed straight to the load? I see the manual lists these modes. But I don't see how it decides what to do.
How quiet (or loud) is an EG4 3000EHV with no PV and only batteries? Would be supporting a critical load subpanel with only 1 or 2 rack batteries as a UPS. So for 98% of the time, it would be on grid power with fully charged batteries standing by. In a grid outage, the batteries would supply...
Ah ha, I wasn't connecting the dots that it was the same single piece of internal hardware, not an inverter and a separate charger under the hood. So with a 50amp grid input, it can use up to 25 amps of that for charging, leaving a minimum of 25 amps to load. Which matches the 25 amp inverter...
