The grounding of the inverter and the lightning rod of the building that inverter installed cannot be
the same, the two need to be separated (as shown inFigure3-28), or, lightning stroke will damage
the inverter.
l
The grounding of the inverter should be directly connected to the grounding system, and the
impedance should be less than 20mΩ.

Before connecting to the grid, first make sure that the grid voltage and frequency meet the requirements
of the inverter. For details, please see

Technical Specifications
. Otherwise, please contact the
electricity company to solve.
Each inverter should be equipped with an independent external three-pole breaker on the AC side to
ensure that the inverter is safely disconnected from the grid. Recommended breaker's rated voltage is
800V, rated current is 250A.
If several inverters need to share a breaker, the breaker needs to be selected according to the total
current.
