I have something strange thing happening w/ my LV6548s operating in SPLIT PHASE.
Any time the load on one of the inverters goes above about 60%( which, coincidentally exceeds the available PV power), the PV power on that inverter drops to almost nothing and the grid kicks in on that inverter. I have about ~7,700+ to total available PV watts at this time of day, or approx 3,550w per LV6548 inverter. Inverters are both set to SBU.
Now, if I drop the usage to about 60% or below on both the PV kicks in at full boat, battery makes up any deficiency, and grid goes to Zero. This is what how I would expect it to work during the day.

Completely normal operation, but only if load is ~60%...:
Note: the 3rd inverter only acts as a battery charger w/ some extra panels I have.
I do notice a difference in output voltages between the inverters when this happens, 112v vs 122v - not huge, but 10v difference might cause this? When it’s woking properly, the voltages are very close to each other.
I read somewhere there is a firmware update that addresses this voltage difference?
Anyone have any ideas? I’ve tried all kinds of things and nothing works short of turning some shit off….
