6 FAQs about [The maximum output voltage of photovoltaic inverter]

What is the maximum output power of an inverter?

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. Under this voltage, no matter how large the module power is, the full-load output is impossible. 2. High grid voltage There are two conditions which might lead to a slightly high grid voltage.

What is the maximum output current of a solar inverter?

Under the condition of rated voltage of the grid, the maximum output current can reach the rated output power, but if under the rated voltage, the maximum output current cannot be output at a full load. Take the 15kW off grid solar inverter for example. Its maximum output current is27.4A.

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.

What is the maximum voltage of a photovoltaic system?

Photovoltaic System Voltage, DC Source Circuit, DC Output Circuit - The maximum photovoltaic source and output circuit voltage shall be the rated open-circuit voltage of the photovoltaic power source multiplied by 125%.
