Electric energy storage systems (EESS) store excess energy generated by a linked solar PV system or can be charged from the grid. Battery systems can be connected via either an AC coupled inverter or a DC coupled Hybrid inverter, this would be dependant on whether solar PV is available.

AC Coupled systems convert electrical energy AC from the grid into DC via the inverter so that it can be stored in the battery for later use. Typically at cheaper rates. When this energy is needed the inverter will convert the DC back to AC via the inverter for use in the property.

DC Coupled systems have less conversion loses than an AC coupled system. Solar PV panels generate DC energy which can then be stored directly into the DC battery without conversion the only conversion would be when the energy is required from the battery and the DC would be converted to AC via the inverter. For grid to battery storage the principles are the as using an AC coupled system.

Yes – you can use your battery during a power cut. It will depend on what type of system you have installed and how it is configured. Here are a few factors to consider:

.

Yes, you can charge your electric car with a battery installed at home. You will need a compatible electric vehicle (EV) charger installed in your home to charge your electric car with a home energy storage system. You will also need to ensure that your energy storage system has enough capacity to supply power to your EV charger.

Charging your electric car with a home energy storage system has never been easier especially if you have a chosen the same manufacturer for your Solar PV inverter, battery storage system and Ev charger as this will be easy to manage via the smart app. If you have different manufacturers don’t worry its still simple to set up but may require some tweaking around charging times to get right.
