switch is at ‖OFF‖ status, otherwise high voltage may injure personnel.
WARNING
Each string’s maximum open circuit voltage cannot exceed 1100Vdc, otherwise it could lead to
fire or damage the inverter.
If the inverter was damaged by higher maximum open circuit voltage (higher than 1100Vdc)
product warranty will be forfeited and Growatt will not take any responsibility.
A
．
Each string solar panels should be same brand and same model.
B
．
The total panels power should not exceed 1.25 times of inverter input power.
C. According to the specification of the crimping terminal, determine the stripping length (recommended 8-10, mm), crimp
the wire and terminal with the crimping pliers, and connect them to the corresponding connector housings separately, and
hear the click sound to ensure the connection is good. The picture shows the connection of the DC terminal.
Notice:
Connectors need to be fit with male and female terminals, before connecting panels with inverter please make sure
the positive pole and negative pole, namely the solar panels’positve pole connect to‖+‖ negative pole connect to‖-‖.

．
C. The positive and negative terminals of the panel are connected to the corresponding terminals of the inverter. For
the maximum input current value of each MPPT of different types of inverters, please refer to the following table.
