DC Wire Assembly and Connection
Meeting the following requirements is mandatory. All warranty rights will otherwise be invalid.
3.3.1 Maximum open voltage of each string is less than 600V.
3.3.2 Maximum short circuit current of each PV input is less than inverter allowable limit.
3.3.3 The string is well insulated to ground in all cases.
3.3.4 Make sure that the DC connectors have the correct polarity.
3.3.5 If the PV connectors are not assembled properly and locked into place, arc or overheat may be induced.

Please check if
1. The inverter and mounting bracket have been correctly installed. 2. The inverter's exposed metal surface has a ground
connection. 3. The resistance between PV arrays and ground is greater than 1Mohm. 4. For any unused DC terminals,
there are DC connectors inserted to the terminal and sealed with waterproof caps. 5. The grid voltage at the point of
click
connection of the inverter is within the permitted range. 6. The AC circuit breaker must be correctly rated and wired. 7.
The cable communication connectors have been correctly wired and tightened.
Startup
click
Switch on the DC switch after finishing the above checks, then switch on the AC circuit breaker. When there is sufficient DC
power applied and the grid conditions are met, the inverter will start to operate automatically.
