Frequently Asked Questions

What is a hybrid inverter, and how is it different from a regular solar inverter?

A hybrid inverter can manage power from solar panels, the grid, and a battery bank simultaneously. It can feed solar energy to your home, sell excess to the grid, and charge/discharge batteries. A regular grid-tie inverter only feeds solar power to the grid/house and does not manage batteries for backup.

Will this inverter power my home during a blackout?

Yes! In battery mode, it automatically and instantly switches to power essential loads from the batteries when the grid fails, ensuring an uninterrupted power supply for connected circuits.

What type of battery is compatible?

It is compatible with various battery types, including lead-acid and lithium-ion batteries (via communication interface), offering flexibility for your energy storage setup.
