6 FAQs about [Energy storage inverter mode]

What is the working mode of the inverter?

Except for EPS, the inverter automatically enters according to the working conditions, and other modes need to be manually selected by the customer. Working mode: Self Use, Feed-in priority, Backup mode, EPS, Manual, Generator mode, peak shaving. time axis:Allowed discharging period、forced charging period.

How many working modes does the G4 energy storage inverter have?

The G4 energy storage inverter has 7 working modes and two sets of flexible time axes. Except for EPS, the inverter automatically enters according to the working conditions, and other modes need to be manually selected by the customer. Working mode: Self Use, Feed-in priority, Backup mode, EPS, Manual, Generator mode, peak shaving.

How do I set up energy storage?

There are four different energy storage operating modes available: (1) Self Use (2) Feed In Priority (3) Backup (4) Off Grid You can turn these modes on and off by following this path: Advanced Settings > Storage Energy Set > Storage Mode Select > use the Up and Down buttons to cycle between the four modes and press Enter to select one.

How does an energy storage inverter work?

Now the energy storage inverter is generally equipped with an anti-islanding device. When the grid voltage is 0, the inverter will stop working. When the output of the solar battery reaches the output power required by the energy storage inverter, the inverter will automatically start running.

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.
