needed to protect the system from tripping, either type A or type AB RCD are
compatible with the inverter.
The integrated leakage current detector of inverter is able to detect the real time
external current leakage. When a leakage current detected exceeds the limitation
the inverter will be disconnected from grid quickly, if an external leakage current
device is connected, the action current should be 300mA or higher.
