Lithium Storage 2.4kWH / 3.5kWH


The US2000C and US3000C are state-of-the-art lithium storage systems: With the highest level of safety and a long service life – even with regular deep discharge – they meet the high demands placed on solar storage systems. The fast charging and discharging properties typical of lithium batteries allow to store or release a large amount of energy in a short period of time. This predestines the US2000C and US3000C for use in solar storage solutions for private households.
