A:
Inverter detected component input voltage is too high, set of series voltage is measured with a multimeter, and with the label on the right side of the fuselage, in comparison with the dc input voltage range of dc input voltage range, if measure the voltage more than less group list number.
-
A:
Detect ac frequency inverter range of inverter safety set, when the inverter error, can be on the inverter screen to view the current of the power grid frequency, please select the appropriate safety according to the actual power grid voltage
-
A:
The inverter detects that the voltage of the power grid is near the upper limit of the standard. Therefore, the inverter screen reminds the AC voltage to be high, so please adjust the inverter safety regulation according to the actual voltage of the power grid.
-
A:
Inverter detected components of insulation resistance is low, plug in turn set series, confirm whether the fault components for single string cause, which is a series of component error, check whether the ground of this series of components and cable broken skin.
-
A:
The inverter detects that the leakage current is too large, and the string is inserted in sequence to confirm whether the fault is caused by a single string component, which string of components is wrongly reported, and whether the cable of the string component is broken.

A:
