FAQS

What is the primary use of a power inverter?

A power inverter is primarily used to convert direct current into alternating current. It is mainly used to store electrical energy in the grid into energy storage devices such as batteries and release it to the load when needed. It is usually used in renewable energy power generation systems such as solar energy and wind energy.

What is an energy storage inverter?

An energy storage inverter represents the latest generation of inverters available on the market. Its primary function is to convert alternating current (AC) into direct current (DC) and store it in batteries. During a power outage, the inverter converts the DC stored in the batteries back into AC for user consumption.

What does an energy storage inverter convert AC power into?

An energy storage inverter is used to convert electrical energy from the grid or other AC power source into DC power to charge energy storage devices.

What is the difference between energy storage inverters & PV inverter systems?

The main difference with energy storage inverters is that they are capable of two-way power conversion – from DC to AC, and vice versa. It’s this switch between currents that enables energy storage inverters to store energy, as the name implies. In a regular PV inverter system, any excess power that you do not consume is fed back to the grid.

Do you need an energy storage inverter?

To store energy for yourself – in case of a blackout or extreme weather when the grid is down – you need to store it locally. But you can only store DC power in the battery. So, you’ll need an energy storage inverter to convert the AC power that your PV inverter produces back into storable DC power.
