We have an offgrid 8k sq ft house (4ksq ft of it is basement
We got 12 felicity solar batteries 10kwh each 6 eg 4s 6500.
We were told not to put more than 6 batteries in parallel. We have two sets of 2 victron bus bars connected to 6 batteries each. Invertor 1, 2 and 4 (all sp1) are going to battery bank 1 and invertor 3 and 5, 6 (sp2) are going to battery bank 2. This allow us to never over use one battery bank.
There are two house panels that are separated so inverter 1 and 3 are in split phase and have no issues for lights, AC etc. They are not connected with other inverters.
The other panel is connected to inverter 2 and 4, 5 and 6 (going left to right). 2 and 4 are 2p1 ie line 1. Invertor 5/6 are in parallel as 2p2.
They are connected to the panel with 2 70 amp breakers.
We recently add the two extra inverters (5 and 6). Prior to this we had no flickering light issues.
Currently if we run 1 ac we start getting flickering lights nonstop. IF we run 2 acs at same time we do not get flickering lights, go figure. IF I turn off either of 70amp breakers when there is flickering lights it will stop (likely because it increasing the load for the 2 remaining eg4s).
We upgraded to the newest firmware. The neutral is bonded to ground to at the panel only.
I DID NOTICE THAT VOLTAGE JUMPS AROUND FROM 118-124 WHEN FLICKERING. Signature solar has no solutions for me. Anyone have any ideas?
