In the off-grid solar system, the correct startup sequence and shutdown sequence of the inverter are very important.
Wrong operation may cause damage to the inverter.
So, next I want to show you: About the startup sequence:
First, turn on the battery switch, second turn on the battery switch of the single phase inverter,
third turn on the solar panel switch, fourth, turn on the output, and finally turn on the load;
Important hint:Prohibit booting/starting with load
About shutdown sequence:
the first,Turn off the load,
second , turn off the output of the inverter,
third,turn off the solar panel switch, fouth turn off the battery switch of the inverter, and finally turn off the battery switch.
