At the heart of Cenpac Storage Li is the lithium-ion based Engion Family storage battery from VARTA Storage. The cells have an expected service life of up to 6,000 charge cycles and a loading capacity of 90%. The storage system is designed to last for more than 20 years based on a rate of 250 charge cycles per year as the company states. The in-built emergency power option ensures power is supplied in the event of a power failure. The system operates according to a modular design principle and can be expanded on a modular basis from 3.7 kWh up to 13.8 kWh. Additional modules can be built in at any time if household power consumption increases. Additionally Centrosolar also presents its new S-Class Vision 60 black photovoltaic module. The module is equipped with a special type of solar glass on the front and back sides. The S-Class Vision consists of 60 high-performance cells and generates an output of 240 Wp to 260 Wp.
