Install a inverter at each location using recommended hardware.Step 2: Connect the AC cable of the inverter and connect it by with the AC bus cables (L brown, N blue, G green and yellow). Please do not exceed the maximum current of the AC bus cable.Step 3: Connect the inverter to the photovoltaic module, please do not exceed the maximum input voltage of the VOC inverter on the photovoltaic panel.Step 4: Install the AC branch circuit junction box and connect the conductors of the AC bus cable. Connect the AC branch circuit junction box to the public grid interconnection point.Step 5: Carefully check all inverters, connectors, and cables for correctness and good connection.Step 6: Open the AC circuit breaker on each AC branch circuit of the inverter.Step 7: Turn on the main AC circuit breaker of the public power grid. Your system will start
