When the wind and solar complementary power supply system does not operate normally, the following methods can be used to test the equipment, which must be operated by professional technicians.

A. Wind turbine

1, test the wind turbine is normal. (Test must be tested in the case of open circuit)

Testing instructions: the output of the wind turbine for three-phase alternating current, multimeter testing should be in line with product specifications (testing site wind must be up to standard), whether the phenomenon of iron phase, such as three-phase voltage is not the same or all no voltage, it is likely to appear out of phase. Encounter this situation must contact the product supplier.

2, test the wind turbine brake function is normal. (The test must be open-circuit situation) test instructions: wind turbine in the case of rotation, such as the three-phase short-circuit wind turbine will make the brake state, the speed will also be significantly reduced, if the three-phase short-circuit wind turbine has not found the brake site, this situation must contact the product supply

3, test the wind turbine connection.

Testing instructions: check whether the connection between the wind turbine and the power supply system is consistent with the drawings, test whether the wind turbine is firmly connected at the junction.

4、Detect the charging current of the wind turbine

Testing instructions: In the case of wind power reaching the charging range of the product, test whether the charging current of the wind turbine to the battery is normal. If there are any abnormalities, please contact the product supplier.

II. Solar panels

1、Inspect the surface of the solar panel

Inspection instructions: Check whether the surface of the solar panel is broken, check whether the terminals are broken.

2、Detect the solar panel voltage. (This test must be carried out in open circuit.) Testing instructions: Use a multimeter to test whether the open circuit voltage of the solar panel reaches the product specification range. If the voltage is found to be low or abnormal, please contact the supplier immediately. 3、Check the solar panel circuit

Testing instructions:Check whether the wiring of the solar panel is consistent with the drawing, check whether the terminals are firmly connected, and test whether the solar panel has charging current to the battery after connecting the system. (With the sun) If the charging current is abnormal, please contact the product supplier.
