Hi.
Apex 300 is in UPS mode, charging and passing through the input to output. I am charging with 2000-2200 watts/
However, when output power goes above the input, i.e. 3000 watts, the charging stops (i.e. if my Apex300 is 100%, it would just shut off AC input and stop charging, just draining the battery).
if I turn off grid self adaptation, Apex shuts off AC with no warning.
Could someone explain the passthrough feature for Apex 300? Thanks
