Lithium storage unit US5000




Solar Lithium storage unit 48 V / 4,8 kWh

The 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 constantly
monitors the status of individual cells and also
provides protection against excessive levels of charge, voltage and temperature. This is how the BMS
prevents an accumulator from failing prematurely as a result of ambient factors or operator error.

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.

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.
