18kPV + 1 PowerPro Bat fault

[cowduck]

Hello,

Lately I am getting Bat fault and Bat voltage high errors. When this happens all the lights at home flicker.

Battery and Inverter are on the latest firmware.

Any ideas? @EG4_Jared ?

I would check the battery communication, verify the brand of lithium being used, and also check to see if the battery is indicating a fault.

Also, confirm the voltage of the battery is not exceeding 59.5v, which would prompt the Bat Volt High.

On the inverter. Battery type is set to Lithium. Lithium brand is set to 1. Should it be set to 0?


System Charge SOC Limit(%) was set to 101% for some reason. I changed it down to 100%. Do you think that was causing the Bat Volt High errors?

 

[EG4_Jared]

It might be the case. However, if using lithium brand "1", ensure that the PowerPro is configured for CAN EG4/LUX protocol and not the LUX.

The protocol on the battery itself is EG4/LUX. Communication cable looks good and everything is tight.

Does this give you the additional battery information on the monitoring site? If not, the PowerPro/inverter may not be on the latest firmware and I would suggest updating the firmware or trying with Lithium Brand "0" with CAN LUX.

Looks like this.

Could you DM your serial number? I want to look at the data.
