Inverters not charging from grid when battery has reached shut down SOC
Hello, I have three 8kW Sunsynks connected in three phase with 30kWh of battery storage (6 x eTowers batteries) - there is no PV connected to the system presently. The system is used to run some pumps on a farm. If load-shedding extends beyond the 2 hour mark, then the inverters reach their 15% SOC shut down setting (configured in battery setup page), and turn off. My sense was that when the grid returns, the inverters would naturally begin charging the batteries up again, but this is not the case. The inverters stay in the shutdown mode. Even when I reset the Alarm (toggling the On/Off button), the inverters do not automatically start charging the batteries. I need to go into the battery settings and reduce the shut down SOC settings in order for the inverters to go back into "Normal" mode and start charging the batteries. Is there any way of setting up the inverters in UPS mode, so that they automatically start charging the batteries when the grid returns, even if they have reached their shut down SOC? Many thanks,
Ryan
Yes the system can be sent as a ups as your installer to help change the settings
