The solar inverter is the safety control center of PV system. Thus, during the PV system operation, the inverter condition, including the temperature and operation of interval cavity and main element, the bus voltage and the communication among chips, shall be inspected from time to time.
If the solar power input is reversed, the power will form a short circuit through the anti-parallel diode. According to the characteristics of the solar module, the voltage of the solar power supply When pulled down, the voltage value is only the sum of the forward voltage drop of the two diodes, which will not damage the electrolytic capacitor.
Therefore, the solar system related equipment is generally designed with anti-reverse connection circuits to ensure that the solar equipment is protected from damage when the input power is reversed. The simplest anti-reverse circuit is to connect a diode in series with the input circuit, as shown in Figure 1.
The PB2200L pumping inverter produced by Shenzhen Solartech Company was used for reverse connection test. Since the inverter has an anti-reverse connection circuit, the anti-reverse diode in the circuit should be short-circuited with a copper wire.
