Multiplus randomly passthru switching

Hello

1. Question

I have Mutliplus 24/3000/70-50 in (Easysolar) with Lifepo4 battery, I updated the firmware to 2610497, with this firmware is possible to control the inverter by SoC of battery, I set SoC low shut-down to 20% and restart to 25%, the inverter always turns off on 20%, but randomly restart, sometime on 25%, but sometimes at 30%, one at 78% ect.

2. Question

I have another installation with Mutliplus 48/3000/70-50 fw: 2620497, But this has another issue, after reconfiguration or if I manually turn off the inverter, the inverter does not start immediately, but after several minutes(10min or more), for instant restart, I have to switch to charger mode for few seconds and then quickly switch to ON.

@soky

It is best not to use the VE Bus SOC on an ESS system. That will solve the first one.

For number 2 the battery bank is probably not able to precharge or handle the start up of the system.

1. I'm not using ESS, I enable DVCC on CCGX
2. But, if I switch to turn on from OFF, VE.Bus not working, I need switch to charge mode (multiplus not charging), battery has float voltage 54V, after that fast re-switch to ON mode.
