You may not use all of the electricity that your Solar PV panels generate electricity throughout the day.
For many businesses they will require electricity in the evening time when Solar PV production is lower or in the night time. In this case, a battery is installed to store the energy gained during the daylight hours so it can be used up whenever it’s needed.
Battery storage allows you to make even more savings on your electricity bill.
A battery’s efficient lifetime depends on the technology and the way the battery is used. Manufacturers generally give an expected lifetime in years and/or in ‘charge-discharge cycles.
There are two ways of linking a battery storage system into a Solar PV system – DC coupling, and AC coupling.
DC coupled batteries take power directly from the solar PV panels, and then feed the power to the inverter to be converted to AC when it is ready to be used.
AC coupled batteries are installed on the grid-side, where the solar PV’s DC has already been converted to AC. A separate inverter converts the AC back to DC for storing in the battery. When the battery discharges, the same separate inverter converts the DC back to AC.
This type of battery may allow other functions besides storing solar PV excess electricity, such as storing cheaper night rate electricity to use during the day.
