Lithium Storage System UP2500 – 24V

Lithium Storage System UP2500

The UP2500 is a state-of-the-art lithium storage system: with the highest level of safety and a long service life – even with regular deep discharge – it meets the high demands placed on solar storage systems. The fast charging and discharging properties typical of lithium batteries make it possible to store or release a large amount of energy in a short period of time. This predestines the UP2500 for its use in solar storage solutions for private households.
