Note: if there is no protection diode connected to the end of the photovoltaic DC input, it is forbidden to close the switches (Q1 and Q2) at the same time, otherwise, it will damage the module of photovoltaic cell

The notes below should be considered for the AC debug

1. Power On Sequencing:Firstly open Q2 ,and then close Q1;

notice:

(1) If there is no protection diode connected to the port of input-bus, it is forbidden to close photovoltaic cell switch "Q1" and input switch of power grid "Q2" at the same time, otherwise it will damage the module of photovoltaic cell

 

(2) When need to transform the power supply mode from power frequency to photovoltaic cell; you only need to turn off "Q1"firstly and then close "Q2".
