Lithium storage unit Pylontech US2000C/3000C

Solar lithium storage unit 48V / 2.4kWh (US2000C) / 3.5kWh (US3000C)
The Pylontech 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.
