Mmmmm
Murphy came to visit....
This morning my system went from 34% to 18% in an instant and immediately switched to grid as my SOC lower limit was set to 22%. Load at the time was 900w.
I checked the battery voltage graph and there was no sudden drop there so it did not match the SOC drop.
I went to the garage and checked the SOC lights under the batteries. 2 of my AM-2's still had 2 SOC lights on, but the 3rd had no lights on. The one with no lights is in the middle on the wall and therefore in the middle of the battery cabling (don't have a busbar). I highly doubt this is a balancing issue as I checked these lights a week ago when the system showed 50% SOC and all three batteries had the same number of SOC lights on.
I have a suspicion I may have a sick Hubble in the middle of my wall. It is 1 of the original 2 installed in Feb last year, so I will call the installer on Monday and show him my pics and the SOC+Voltage graphs and ask him what's up. For now I have set the SOC limit to 35% to avoid another sudden drop and I'll do another lights check tomorrow morning.
