How do I set the Quatro 8000 to shut down at 30% SOC on a completely off grid system. It is connected to 2 SmartSolars and 2 Freedom Won batteries of each 15/11 kWh. There are no assistants on the system. I tried to set the shut down with VEConnect on the Quatro but it goes down to below 10% SOC before shutting down.
