6 FAQs about Solar Inverter voltage is higher than grid voltage

Does a solar inverter increase a grid voltage?

In order for power to flow from your home to the grid, the voltage from the solar inverter has to produce a voltage that is a couple of volts higher than the grid voltage. Voila, Solar Voltage Rise. In the ideal situation, the voltage rise is not a problem: the inverter increases the grid voltage from 240 volts to 242 volts.

How high can an inverter be above the grid?

The inverter must therefore have a higher voltage than the grid, but only by a small amount: typically no more than 2% above the grid’s voltage. For example, in Australia, where the standard grid voltage is 230V, a 2% rise means that the inverter voltage can rise to at least 4.6V above the grid, or to 235.6V.

How many volts does a solar inverter produce?

Let's say it produces 10 amperes, and the grid has a resistance of 1 ohm. In this case, the voltage will rise to 220 volts at the inverter. If the solar inverter sees a high grid voltage of let's say 250 volts, it does the same. Only when the grid voltage exceeds some sane limit, will the solar inverter stop production.

Can a solar inverter send 20 amps back to the grid?

If your inverter wants to send 20 amps back to the grid, then we should “let it flow”. The only way left to balance the equation is to increase the voltage even more. The higher your cable’s resistance is, the higher the voltage must be to force the current to the street. Solar Voltage Rise starts becoming a problem.

What is a 'voltage rise' on an inverter?

The AS/NZS 4777 standard stipulates that the ‘Voltage Rise’ on the AC cable between the point of supply and your inverter must be no more than 2% (which at the upper limit of 253 Volts will equal to 5 Volts). Inverters must operate at a higher voltage that the grid in order for the energy to flow from the inverter.

What voltage does an inverter need to operate?

Inverters must operate at a higher voltage that the grid in order for the energy to flow from the inverter. So for an inverter to be at an operation level when the supply voltage is 253 Volts (including a voltage rise of 2%), the AC output of the inverter would have to be higher than 253 Volts, plus the 2% voltage rise (5 Volts).
