One battery won't discharge from 100% #291

Closed adevapp closed 3 months ago

adevapp commented 3 months ago

hi there, since installing the experiment version of the software and using the fast charge function in the software, one of the batteries stays at 100% and doesn't discharge. There are 3 batteries, and 1 is paired together as one unit. The paired batteries do work as expected and are charging/discharging. The system sees 2 batteries, but the second one won't discharge at all.

LX F16.4-H x 3 stacks. Invertor: GW25K-ET (AS4777-2 2020)

I've tried restarting the whole stack including batteries to no end. I've depleted the paired batteries and the 100% charge battery simply won't discharge. Is there a setting to check for this?

I do see these in the logs from time to time: Diag Status changed to BMS: Discharge current low, APP: Discharge current too low, SOC delta too volatile, PF value set, Real power limit set. Charge batteries: Error executing script. Invalid data for call_service at pos 1: expected str for dictionary value @ data['value']

Could it be the above values are not set properly? If so, what should the value be? "yes", "no", null or something else?

Seems to be fixed by manually setting: battery_discharge_current comparing the 2 stacks to the same value. Is there an officially recommended value for this? I'll check with Goodwe Support.

Seems 25 is the value based on this doc: https://www.goodwe.com.au/Ftp/Downloads/Datasheet/AU/GW_Lynx%20Home%20F%20PLUS+%20Series%20(HV)_Datasheet-AU.pdf
