PLENTICORE plus – simply versatile

More choices yet simple handling – the perfect description of the new battery inverter from KOSTAL Solar Electric. As the PLENTICORE plus name suggests, it offers numerous possible uses and options, with the “PLENTI” part coming from the English “plenty” and “core” illustrating that all important functionalities are combined in just one unit. And of course KOSTAL’s new battery inverter can be found at the very core of a PV system.
