1.The rated power output
The rated power output means the ability of the solar inverter
to supply power to the load.High rated power output of solar inverters can bring more electricity load.
2.Power-factor of load
In the allowed range of inverter load power factor, recommended value of 0.7 to 1.0. The higher factor, the greater efficiency.
3.Rated output frequency
The output frequency of the inverter should be a relatively stable value. Generally, under normal working conditions, the deviation is about 1% can be accept.
4.The stability of the output voltage
When the input voltage changes, the steady output voltage variation should not be more than about 5% of the rating, at the same time when the load mutates, the output voltage deviation should not exceed 10%.
6. The current mainstream inverter nominal efficiency between 80% and 95%, for a small power inverter
should not be less than 85%.
