Performance & Energy Optimization

The LUNA2000-7-S1 delivers a nominal energy of 7 kWh per module and supports fast charging and discharging at 3.5 kW per battery module. Module-level energy optimization increases usable energy by up to 40%. The maximum charging power is 10,000 W, while the maximum discharge power is 4,400 W when the module is operated with the SUN2000-7KTL-M1.

The maximum input and output power per string is 10.5 kW. The DC battery’s operating voltage range spans from 600 V to 980 V with a maximum operating current of 16.7 A.

Safety & Durability

The battery module features the highest safety certification from TÜV Rheinland. Cell-level temperature management with 4 temperature sensors for 8 cells ensures precise monitoring across the entire operating temperature range of -20 °C to +55 °C. The IP65 rating reliably protects the module from dust and water jets.

The housing is pressure-resistant up to 5 tonnes and provides underwater protection to a depth of 40 cm for 72 hours. These features make the LUNA2000-7-S1 particularly resistant to mechanical stress and temporary flooding. For operating altitudes above 2,000 m, derating must be considered, with a maximum operating altitude of 4,000 m.

Compatibility & Expandability

The LUNA2000-7-S1 is compatible with the HUAWEI SmartString ESS (5 kWh–30 kWh) and inverter models SUN2000-3/4/5/6/8/10KTL-M1. The S1 family offers 9 capacity options from 5 to 21 kWh, allowing storage capacity to be tailored to different requirements.

When operating 3 MB0 inverters in parallel, a maximum storage capacity of 252 kWh can be achieved, requiring 12 battery modules. The relative humidity during operation can cover the entire range from 0 %RH to 100 %RH.
