Two 5.12/5.32kWh batteries have a continuous discharge of 100A. This means that the maximum charge/discharge is limited to the 90A of the inverter. Other Current Limiting Factors Your current should also be suitable for the rated current of your battery cables.
Please refer to the manual for the charge and discharge limit of your inverter. When selecting the charge and discharge current limits you will always be limited to the lowest current value whether that is the inverter or the batteries. For example, the 3.6kW Ecco inverter has a 90A maximum charge/discharge current.
The battery charge/discharge rates are measured in current (A). To work out the maximum charge/discharge power of the battery you will multiply this current (A) by the BMS voltage. The BMS voltage of a battery will vary between make/model/manufacturer so always refer to your batteries datasheet/manual for the correct current and voltage limits.
One battery charging or discharging at 50A will discharge at 58.4V x 50A = 2.92kWh. The charge and discharge current in the inverter settings is the total charge and discharge current of all of the batteries connected so 2 batteries would be able to charge or discharge at 100A, 3 batteries at 150A, etc.
