Differences between energy storage inverter and grid-connected inverter

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.

Should I choose a hybrid or battery solar inverter?

Whether you choose a hybrid inverter or a battery inverter for your energy storage requirements, you can feel confident that our Hoymiles energy storage inverters will help to conserve power when you most need it. Here is a quick recap of the main differences between hybrid and battery solar inverters:

Do PV inverters convert DC to AC?

You may already know that regular PV inverters convert direct current (DC) energy to alternating (AC) energy. The main difference with energy storage inverters is that they are capable of two-way power conversion – from DC to AC, and vice versa.

What is a battery inverter used for?

Battery inverters are mostly used for PV retrofit, either in string systems or microinverter systems. For instance, if you already have a PV system, and want to add energy storage functionality, then you need a battery inverter to connect to your system for power backup – i.e. your battery.

What is a hybrid inverter?

Hybrid inverters are unique in that they offer a higher DC-to-AC ratio , but with no energy loss , as excess power produced by your solar system will be stored in the battery. But what does a DC-to-AC ratio mean? In short, it’s the ratio of the installed capacity of your PV modules to the rated output power of your PV inverter.
