SANTERNO SUNWAY TG- TG TE

Listed below are the requirements for initial action on a failed inverter. Before proceeding with any operation: A) Verify that the model is correct; B) Carefully follow all instructions provided in the manufacturer’s operation and maintenance manual; C) Ensure that the intervention is carried out by trained personnel; D) Since this is a photovoltaic inverter with a DC input that is always live, strictly observe all applicable safety regulations.
