1. The default frequency of this inverter is 0-50HZ, and the reverse function is closed by default. If you need to change it, please contact us.
2. Please try to meet the recommended voltage for DC input, otherwise the conversion power of solar energy will be reduced.
3. DC and AC power can not be used at the same time, otherwise it will damage the inverter and solar panels
4. The solar inverter is only suitable for solar panels to generate power to drive fans, water pumps and other loads. It can be selected according to the voltage and power of the motor. If the depth of the submersible pump exceeds 30 meters, it is recommended to zoom in 1-2 levels.
5. Regarding how to configure solar panels (assuming that the solar panels are configured as 24V 300W and the motor power is 4KW), such as 220V motors, the total voltage of solar panels in series meets DC 200V-400V (it is best to configure 320V), then 380V motors, The series voltage meets the DC 400V-700V (optimal configuration 540V) voltage calculation method: Take the best configuration 540V as an example, 540V/24V≈23. The power calculation method is: 1.2 times larger than the motor power, the solar panel power is 300W, the motor is 4KW, (4000X1.2)/300=16 (then the best configuration is to use 23, take the maximum value)
