I have (2) LV6548 in parallel. It's finally getting warmer in Northern Michigan and I kicked on the central air and started noticing this problem.
My inverters are set to Solar/Battery/Utility. I have 10,000 watts of solar and 400ah of 48v batteries.
When my load is higher, I run into this issue. For example earlier today, I had a load of about 5000 watts (higher then usual). Solar was providing about 1/2 the power and the other 1/2 pulling from batteries without issue.
Then my water pump kick on (kids playing with sprinkler outside).
Once this happened, the entire load from that inverter shifted over to grid. Even though the battery was well over 90% charged. It would not shift back.
I finally turned off the breaker for the grid assist. Then it started pulling from battery as desired. Flipped breaker back in and it was fine again, until the well pump went off, then it was stuck on grid again.
It doesn't seem to be respecting the solar/battery/utility setting. I can see it failing over for about 15-20 seconds (when well pump goes off, if pulling from the same inverter exceeding the 6500 watt rating). However, I would think it should fail back to battery if this situation occurs.
Any advise?
