FAQs 6

How to fix overvoltage problem in a solar system?

The first step to fix the overvoltage problem in a solar system starts with the checking of its solar panel’s voltage by performing an Open Circuit Voltage Test as per the below-given instructions: Direct the solar panels towards the sun during peak sunlight hours. Bring a multimeter and set it to DC Voltage measurement.

What causes overvoltage in solar panels?

Overvoltage is one of the most common issues that impact your panels’ performance, it happens when the grid voltage exceeds 258 volts and it when more solar is generated than power being used. When the voltage gets to 253 volts it becomes too high for solar AC to reach the grid, this may result in lost feed-in tariff for your home.

What happens if grid voltage is higher than solar power?

Electricity flows from higher voltage to lower voltage. This means if the grid voltage is higher than the voltage produced by rooftop solar, that solar power system will be unable to export energy.

What is a 12V solar panel rated voltage?

The rated terminal voltage of a typical 12V solar panel is around 17V, this voltage is further regulated by a solar charge controller around 13 to 15 Volts to charge batteries. Sometimes solar panels produce overvoltage due to various factors that can be harmful to the solar power system.

How to reduce the voltage of a solar panel?

Solar panels are connected in two-part wired series to get more voltage out of them. However, if solar panels are producing too much voltage then making the connection parallel can reduce the voltage. This can be done by making some changes to the junction box. This method is not easy and should be done by an expert solar technician.

What happens if grid voltage is too high?

If grid voltage is already too high your inverter is no longer able to overcome it and instead shuts itself off. For example, if your solars are producing lots of power constantly for 10 minutes, then the grid will go over 255volts, causing an overvoltage reaction.
