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. We work with manufacturers such as Pylontech, Solarwatt, Sonnen and LG Chem.
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.
