Technical FAQs 4

Can you add a battery to a solar inverter?

It’s relatively easy to add a battery to your existing solar panel system, but the level of ease depends on the type of solar inverter you have. If your inverter isn’t compatible with a battery, the simpler and more affordable solution is to install an AC-coupled battery system.

Can a string inverter be used as a backup battery?

It can effectively upgrade any existing string inverter system by adding a backup battery. Capable of being grid-interactive, it allows users to store surplus power and sell it back to the grid when demand peaks and the price of electricity is at its highest.

What is a goodwe SBP battery storage retrofit?

The GoodWe SBP series is the world’s first AC-coupled battery storage retrofit solution with UPS function for single-phase and three-phase systems. It can effectively upgrade any existing string inverter system by adding a backup battery.

What if my inverter is not compatible with a battery?

If your inverter isn’t compatible with a battery, the simpler and more affordable solution is to install an AC-coupled battery system. This setup allows your battery to operate independently from your solar panels, avoiding the need for major equipment upgrades.
