1.Rated output power
The rated output power of the solar inverter determines the output power, and the average household is about 3000W. If use the inverter as a standby power supply, only need to calculate the power consuming, according to the rated output power of the inverter is chosen to match the model.
2.Maximum output current
The maximum output current of the solar inverter involves the type selection of the circuit breaker, which is related to safety. It is necessary to pay special attention to the value of the solar powered inverter when installing the inverter.
3.Voltage and frequency of power grid
Select inverters that need to be connected to the grid. These values are the grid parameters that can be used in conjunction with the solar inverter. The power grid of China is 220V, 50Hz. If you choose to buy other countries’ products, we must pay attention to these two parameters, or finally choose a transformer.
4.Maximum harmonic content
The output voltage and current waveform of solar inverter with distortion phenomenon, it is easy to affect the power consumption of its equipment performance if this value is too large, Chinese safety regulations require maximum harmonic content must be <5% rated power. In the selection process of solar inverter, the smaller the value, the better. But the current inverter technology is difficult to avoid this problem, so choose according to the domestic safety regulation value.
5.Power factor
The power factor cosφ represents the proportion of active power in the total power of the solar power inverter.
