Issue: I have recently upgraded my system with an additional battery (the Dyness in the image), I had someone come and fit it. My issues are as follow. - Batteries are 100ah, but on solar assist when both are connected, it shows 75ah each (150ah total) When one is connected, it shows 100ah. - Master Battery runs down faster than Slave ( in the morning, the Master would be around on 30% and slave would be over 50% ) What I have tried: - I have tried to make the other Battery Master (Pins) & swapped the Comm ports on the two(so that the Raspbery Pi) runs of the new Master (but it only picked up One Battery) - I did not move any power cables between them - Not sure if it could be the cables System: Inverter: Mercer Dyness 8KW (SOL-I-AX-8M2) Battery: Mercer Dyness 4.8KW Lithium Battery A48100 & Dyness 4.8KW Lithium Battery A48100 (the new Battery) Monitoring System: Solar Assistant Appreciate any advise.
