There are many articles about inverters, most of which are lengthy. Now we summarize the basic technical parameters of inverters.
1. DC input power conditions: The input current voltage fluctuation range is ±15% of the rated voltage of the battery pack
2. Rated output voltage: The rated voltage that the inverter should output when the rated current is output under the specified input power supply conditions. Voltage fluctuation range: single-phase 220V±5%, three-phase 380±5%
3. Rated output frequency: Under the specified conditions, the rated output frequency of fixed frequency inverter is 50HZ, fluctuation range: 50HZ±2%
4. Rated output current: The rated current value that the inverter should output under the specified output frequency and load power factor.
5. Efficiency: ratio of inverter output active power to input active power under rated output voltage, output current and specified load power factor
6. Load power factor: The allowable variation range of the inverter load power factor is 0.7-1.0
7. Protection function: Inverter should be set to short-circuit protection, over-current protection, over-voltage protection, under-voltage protection and phase loss protection
The above are the reference technical parameters and requirements of the inverter. I hope to be helpful to everyone.
