Hi,
I have Growatt SPH4000 inverter and LiFePo4 battery 200Ah with Seplos BMS. I have one big issue with BMS or with the inverter. My battery is fully charged but the inverter does not stop charging. The inverter is set at the end of charging (example 90%) but the inverter continues to charge until BMS does not activate warning. Inverters have info from BMS and stop to charge the battery but also and not use energy from the battery. Every day I must change the total capacity or the remaining capacity on the battery. Then the inverter starts to use energy from the battery.I had contact with Seplos and Growatt support but did not get any usable response.
From growatt i get responses similar like: Growatt not support issues with battery which is not from Growatt. The inverter is set to SOC to which the battery can be charged (90%). On the Web application from Growatt SOC of battery is presented.
From Seplos I get instructions on how I must set the Growatt inverter. This instruction I got with the inverter and this response is not helping me.
I do not know what I did wrong. Can someone help me?
On BMS:
Settings on inverter:
