Residual-current monitoring unit

The inverter does not require an external residual-current device when operating. If local regulations require the use of a residual-current device, the following must be observed:

• The inverter is compatible with residual-current devices of type A and B that have a rated residual current of 100 mA or higher. Each inverter in the system must be connected to the utility grid via a separate residual-current device.
