6 FAQs about [The photovoltaic inverter phase voltage is too high]

Why is my solar inverter causing a voltage rise?

The maximum voltage rise between your solar inverter and the grid is above the 2% maximum in the Australian Standard, because the resistance in the cable (including any connections) is too high. If this is the case then the installer should have advised you that your AC cabling to the grid needed upgrading before solar could be installed.

Why is the phase voltage of a solar inverter low?

It can be seen from the monitor APP that the phase voltage of AC1 is normal but AC2 and AC3 are relatively low. After the site inspection, it is found that this is because the phase line L1 and the zero line N are connected in an opposite way. When they are exchanged back, the solar inverter works normally. 3.

What is the rated voltage of a 3 phase inverter?

The rated voltage of the single-phase grid is 230V. when the grid voltage is lower than 195.5V or is higher than 253V, principally the inverter shall be stopped. The rated voltage of the three-phase grid is 400V. When the grid voltage is lower than 340V or is higher than 440V, principally, the inverter shall be stopped. 1.

Why do inverters need to be stopped if grid voltage changes?

This is because the grid voltage is not constant and it will change with the changing of the load and current. At the same time, the output voltage of the inverter will be affected by the grid voltage. When the grid encounters abnormal situation, the inverter power supply shall be stopped to avoid more serious damage on the grid.

Why does my solar inverter have an over-voltage error?

But an over-voltage error on your solar inverter may not be your DNSP’s fault. It could be caused by your solar installation or your existing grid connection. Specifically the wires from your inverter and switchboard through to your grid connection point may have too high a resistance. This can be caused by distance, thin wires or bad connections.

Why do PV inverters have to shut down before switching back on?

Effectively, PV households will push local voltage up a smidge. So, to avoid a vicious circle, when the grid voltage reaches 253V (UK DNO's have (by law) to maintain a voltage of 230V -6%/+10%) inverters have to shutdown, and monitor the voltage, before switching back on when it's gone down.
