System shut down this morning
Supply went off, two fault alarms F34 - AC_Overload_Fault at 07:10:14, F41 - Parallel_System_Stop at 07:10:19.
Battery was at 37%, Load was 8.9KW and I switched on Microwave 900w and it all tripped.
Why did this happen 2 x 8.8 KW inverters in parallel ? (should be able to supply 17.6KW)
Should it have switched to grid rather than supply going off?
Battery Charge/discharge set at 150amps on both inverters.
System:-
2 x 8K SG01LP1-EU COMM:e424-MCU:5374
36 x JA 540w panels
9 on each MPPT on each inverter
5 x PylonTech 4.8Kw Batteries

Master came up with at 07:10:14 - F34 - AC_Overload_Fault, and shut of AC, then Slave at 07:10:19 - F41 - Parallel_System_Stop. All restarted and supply came back about 2 mintues.
Have tested same with load 9.1Kw and turning Microwave on and it worked OK.
Do not no why it tripped.
