Lithium storage system Pylontech US5000

Solar Lithium storage unit 48 V / 4,8 kWh

The Pylontech US5000 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 meet 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 US5000 for use in solar storage solutions for private households.

The storage modules comprise a lithium iron phosphate (LiFePo4) accumulator and an integrated battery management system (BMS) which monitors the status of the individual cells. In this way, the BMS prevents the premature failure of a battery due to environmental factors.

The modular layout permits individual configuration of the storage system to achieve the required capacity level, simply by connecting the desired number of modules together.

Pylontech US5000 as ideal energy storage in interaction with the EFFEKTA® AX PV solar inverters. It is ideally suited as storage solutions for solar or island operation with battery support.

Consumers are supplied with electricity from the PV modules on a priority basis. In the first instance, if the PV power supply fails or is insufficient, the batteries deliver the required power. Once the batteries have discharged, the AC source (public power grid) cuts in. Surplus power from the PV modules is used to charge the batteries. Whenever the PV and AC power supply fails, consumers continue to be supplied by batteries.
