6 FAQs about [Photovoltaic inverter shut down at noon]

When do solar inverters shut down?

To prevent a bad situation from getting worse, solar inverters will shut down once grid voltage reaches a set limit. This limit is usually higher for older inverters, while most modern ones can gradually reduce their output as grid voltage rises. South Australia Power Networks receive over 10 complaints a day about grid over voltage.

Why does my solar energy system keep shutting down?

“Our solar energy system occasionally shuts down when the sun is shining. Why is this happening and what can be done to prevent it?” Every inverter features a built-in mechanism that ensures it is automatically disconnected from the power grid when the so-called ‘grid parameters’ are exceeded.

What happens if an inverter feeds power back into the grid?

An inverter that feeds power back into the grid increases the mains voltage by up to 9 V. Electrical domestic appliances such as a washing machine use energy causing the mains voltage to drop. On a sunny day, it is possible that the inverter tries to feed a lot of power into the grid at the same time as little current is being used.

What happens when solar power is sent 'upstream'?

When electricity is sent ‘upstream’ in this way, the owner of the solar power equipment used to generate it will often receive credits that can be used to offset the cost of the grid-sourced electricity they consume later. When the sun sets, the PV cells don’t have any work to do.

How does a power inverter work?

Every inverter features a built-in mechanism that ensures it is automatically disconnected from the power grid when the so-called ‘grid parameters’ are exceeded. These consist of: voltage, current, frequency and grid impedance.

Is solar power a win-win?

As you can see, the solar power generation system of today is uniquely designed to make the best use of both solar-generated and grid-sourced electricity. The results for home and business owners are lower energy bills and higher energy independence—a win-win!
