6 FAQs about [Can a grid-connected inverter be converted into energy storage ]

What is the difference between grid and inverter?

It is important to mention that the system is always connected to the grid but the grid supplies in parallel with the inverter/solar panels the energy demand of the household. Inverter and grid run in parallel feeding power to the loads. Export to the grid can be controlled from 0Watt to maximum power.

Do I need a battery inverter for a solar PV system?

When upgrading the grid-tied system to an energy storage system the only part that changes is the AC Coupled battery inverter add-on. The existing solar PV system doesn’t need to change at all. The AC coupled battery inverter is installed alongside batteries which is then connected directly to your panel or mains.

What is the difference between off-grid and hybrid grid inverters?

This is a major difference between off-grid inverters and hybrid grid inverters, the off-grid system will go into bypass mode if the power demand exceeds the rating of the inverter and all the energy will come from the grid (read more about off-grid set up here)

What happens if a hybrid inverter is not fully charged?

It is important to explain that a hybrid inverter will power the AC-loads but if the energy demand exceeds the capacity of the inverter or the batteries are not fully charged, the surplus energy will be withdrawn from the grid. In simple terms if the load is 5kW but the inverter can only supply 4kW then 1kW will be supplied by the grid.

How does an AC coupled battery inverter work?

The AC coupled battery inverter is installed alongside batteries which is then connected directly to your panel or mains. If the customer wants critical load backup, then those loads will be moved to the backup port (ac output for off-grid mode) . This will give customers the opportunity to select loads that they define as “critical”.

Does a solar PV system need to be changed?

The existing solar PV system doesn’t need to change at all. The AC coupled battery inverter is installed alongside batteries which is then connected directly to your panel or mains. If the customer wants critical load backup, then those loads will be moved to the backup port (ac output for off-grid mode) .
