Q6:How to maintain the solar  inverter？

A6:Before any maintenance work, the electrical connection between the inverter and the power grid should be disconnected first, and then the DC side electrical connection should be disconnected.

       Wait for at least 5 minutes until the discharge of internal components is completed.

       Any faults affecting the safety performance of the inverter must be eliminated immediately before the inverter reopened.

       Avoid unnecessary circuit board contact.

       Obey the electrostatic protection code and wear anti-electrostatic bracelets.

       Pay attention to and abide by the warning signs on the products.

       Pay attention to the hot surface of the inverter. For example, the radiator of power semiconductor still keeps a high temperature for a period of time after the inverter is powered off.

       Finally, after the machine is repaired, it is necessary to ensure that any faults affecting the safety performance of the inverter have been solved before the inverter turned on again.

Q7:What are the functions and classifications of inverters？

Inverter is a device that converts DC electric energy (batteries, batteries) into AC (generally 220V, 50Hz sinusoidal wave). There are many kinds of inverters.

Q7: According to the frequency of AC power, inverter can be divided into low frequency inverter, and high frequency inverter.

       According to the output phase fraction, inverters can be divided into single-phase inverter, three-phase inverter and multi-phase inverter.

       According to the direction of the output power, inverter can be divided into active inverter and passive inverter.

       According to the form of the main circuit, inverters can be divided into single-ended inverter, push-pull inverter, half-bridge inverter and full-bridge inverter.

       According to the types of main switching devices, inverter can be divided into thyristor inverter, transistor inverter, field effect inverter and insulated gate bipolar transistor (IGBT) inverter.

       According to DC power supply, inverter can be divided into voltage source inverters (VSI) and current source inverters (CSI).

       According to the waveform of the output voltage or current, inverter can be divided into pure sine wave inverter and non-pure sine wave inverter.

       According to the control mode, inverters can be divided into frequency modulation (PFM) inverter and pulse width modulation (PWM) inverter.

       According to the switching mode, inverter can be divided into resonant inverter, fixed-frequency hard-switching inverter and fixed-frequency soft-switching inverter.

        According to the commutation mode, inverter can be divided into load commutation inverter and self-commutation inverter..

       Inverter is widely used in air conditioning, home cinema, electric grinding wheel, electric tools, sewing machine, DVD, VCD, computer, TV, washing machine, lampblack machine, refrigerator, video recorder, massager, fan, lighting, etc.
