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.
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. Now that we have the basics down, let's move on to the two types of energy storage inverters that you'll come across on your search – hybrid inverters and battery inverters.
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.
