With a System Performance Index (SPI) of 91.4 %, our DC-coupled storage solution is ahead of the competition, as scientifically confirmed by the latest "2018 Energy Storage Inspection" study conducted by the Berlin University of Applied Sciences (HTW)*.
That's great for us, but what does it mean for you?
With our storage system that consists of the PLENTICORE plus 5.5 and the BYD Battery-Box H11.5, you can make electricity cost savings of approx. €1,107 per year.
But our storage solution delivers yet another financial benefit.
Compared with other systems, which need two inverters, our storage solution requires no additional devices, as the PLENTICORE plus handles energy management for the PV system and battery at the same time. This allows you to save on initial acquisition costs.
