Battery Storage

Home » Battery Storage

Solar PV on it’s own can be a great way to reduce your bills and help towards our planets climate, but by adding battery storage you can maximise your self consumption and reduce your reliance on the grid. 

Battery charging

There are new options for battery storage coming online all the time and with the cost coming down and capacity increasing, it is a great time to start installing battery storage. See below for just some of the options available to you.

Do you choose AC or DC Coupled?

There are a two main options when it comes to battery storage, do you go for an AC or DC coupled system?

DC coupled systems are ideal for when you are thinking of getting solar, they comprise of a hybrid inverter which manages both the solar panels and the battery so keeping all the power on the DC side until required, when the inverter then turns it into AC power. This system reduces the need for additional hardware which in turn reduces costs.

AC coupled systems are better for when you already have solar panels. You can add a AC inverter and battery to an existing system and turn your normal PV system into a solar storage system.
