Luckily, only one of the Charge Controllers failed and one of the DC-to-AC Inverters failed.
And then by "jumpering" the the two battery banks together, they kept the system "functional".
If two Charge Controllers or two DC-to-AC Inverters had failed, that would have been catastrophic.
That "parallel jumper" between the two battery banks is a "band-aid" solution, at best.
The Right-Side battery bank is getting pounded down by the DC-to-AC Inverter,
while the Left-Side battery bank is getting more than its fair share from the Charge Controller.
Measuring the SG's will be very revealing.
