The voltage of the solar inverter fluctuates

4 FAQs about The voltage of the solar inverter fluctuates

Why do solar inverters lose power?

Due toresistance of the line, the voltage loss is inevitable. Then, the voltage of the solar inverter output side should be increased to get transmitted to the grid. Loss of the power generation capacity caused by the rising voltage is mainly attributable to three aspects.

What happens if solar inverter voltage rises?

When the grid voltage rises to certain level, the inverter takes the initiative toreduce the power to prevent the solar inverter from being disconnected. This, though reducing the loss of downtime, will also cause loss of certain power generation capacity. Besides, efficiency loss. When the grid voltage rises, the DC bus voltage will also rise.

What causes a solar inverter to fail?

This fault occurs when the solar inverter loses synchronization with the grid, either due to a grid failure or anomalies in the grid's voltage or frequency. These anomalies might include voltage levels that are too high or too low, or frequency deviations from the standard 50 or 60 Hz, depending on regional standards.

How much power does an off grid solar inverter produce?

Take the 15kW off grid solar inverter for example. Its maximum output current is 27.4A. Under the rated voltage of 400V, the maximum output power is27.4*400*1.732=18.98kW, which can satisfy overload by 1.1 folds. When the voltage of the grid is relatively low or around 340V, then the maximum output power of the inverter is 27.4*340*1.732=16kW.
