I want to use a SUNKET battery 5kWh and MP II 3000 for having power on a festival. The battery BMS can be operated in Victron mode and works with MP II. On an ESS, I would load the ESS Assistant and configure CAN Communication to the battery. Without ESS, CAN-BMS seems to be unavailable.
What are your recommendations to proceed?
Is it sufficient to set the upper charge limit accordingly (the battery has 16 cells, so 55V should work - resulting in 3.45V/cell - max charge voltage is given as 59,2V) and then just run it?
To my understanding, LiFePO4 can be floated
The system will be recharged from time to time via the 230V 1,5kW outlet in my car, a Mitsubishi Outlander Plugin Hybrid. The inverter powering the outlet runs from the 300V traction pack which is automatically or manually recharged by using the combustion engine and the internal generator.
I guess I will need an isolation transformer to connect the car to the MP II because isolation monitoring is carried out by the inverter by checking current flow against circuitry that seems to float at 115V relative to any of the two pins of the 230V socket and that circuitry is connected to chassis gnd.
