Technical FAQs 3

What is a solar charge controller?

A solar charge controller is a device used to regulate the flow of power from solar panels to batteries. It helps to maintain the battery capacity by preventing over- and undercharging, extending battery lifespan. Depending on the type of solar panel and battery voltage, solar charge controllers can be sized between 100W and 15KW.

Do you need a charge controller for a solar system?

If you want to have batteries as part of your home solar system, you’re going to need a charge controller. The chief function of a controller is to protect your batteries. Since batteries are the most expensive part of a solar power system, you want to protect your investment.

Why do solar panels need a charge controller?

A charge controller regulates the flow of electricity from the solar panels to the battery, ensuring that the battery is not overcharged or damaged. It also prevents the battery from discharging back into the panels, which can damage them and reduce efficiency.
