PV production drops when the loads increases or the grid drops.
Sunsynk 12kv 3 phase inverter x2 in paralel with 5x 5kwh sunsynk batteries. 18 x 545w solar panels connected to the master inverter.
Issues we are having is that pv will be doing or example 7000w and the load about 2kw. But when a big load kick in like a the geyser or kettle then the
PV will drop. For example load is 4200 and PV will drop to 3600w until that load shut down then the PV jumls up again
Same when you disconnect the grid the PV production drops to about 3700w max.
Anyone know what the reason can be?

I see that the panels is not shared 9 on the master and 9 on the slave and all 18 is on the master. First start by splitting the panels.
