Safety when Extending the Battery
NOTICE
Damage to battery components and inverters due to high balancing currents
When an additional battery cabinet is integrated into an existing battery, different states of charge and different DC output voltages can cause high balancing currents. High balancing currents can damage battery components and inverters.
- Before connecting a new battery cabinet to the mains, balance the states of charge and DC output voltages.
NOTICE
Damage to battery components and inverters due to incorrect settings on battery management systems
When an additional battery cabinet is integrated into an existing battery, incorrect settings on the battery management systems of the battery cabinets can result in parallel operation of primary battery cabinets. The parallel operation of primary battery cabinets can result in damage to battery components and the inverter.
- Before connecting a new battery cabinet to the mains, balance the states of charge and DC output voltages.
