Huawei LUNA2000 S0 is a modular high-voltage LFP battery system. It uses a LUNA2000-5KW-C0 power module with LUNA2000-5-E0 battery modules.

S0 module count and output

Usable energy is measured at the beginning of life, 25°C, a 0.2C charge and discharge rate and 100% depth of discharge. The headline capacity is therefore not guaranteed energy in every operating state.

Complete tower Usable energy Maximum output Ten-second peak
1 × LUNA2000-5KW-C0 + 1 × LUNA2000-5-E0 5 kWh 2.5 kW 3.5 kW
1 × LUNA2000-5KW-C0 + 2 × LUNA2000-5-E0 10 kWh 5 kW 7 kW
1 × LUNA2000-5KW-C0 + 3 × LUNA2000-5-E0 15 kWh 5 kW 7 kW

A third battery module expands stored energy without raising the two-module power ratings.

S0 power-module and inverter matching

The 5-E0 battery module and 5KW-C0 power module form the S0 system. The compatible inverter map is:

Inverter family Compatible ratings
SUN2000 KTL-L1 2, 3, 3.68, 4, 4.6, 5 and 6 kW
SUN2000 K-LB0 3, 3.68, 4, 4.6, 5 and 6 kW
SUN2000 K-LC0 8 and 10 kW
SUN2000 KTL-M1 3, 4, 5, 6, 8 and 10 kW
SUN2000 K-MAP0 5, 6, 8, 10 and 12 kW
SUN2000 K-MB0 12, 15, 17, 20 and 25 kW
SUN5000 K-LB0 3 and 6 kW
SUN5000 K-MAP0 8 and 12 kW
SUN5000 K-MB0 17 and 25 kW

These are exact family-and-rating combinations. The complete suffix still matters: a similar power rating from another Huawei generation is not automatically compatible. Contact a local engineer for compatibility information before specifying or substituting an inverter for a particular installation.

Outdoor installation is recommended. Indoor installation must follow the product manual.

S0 warranty and current UK status

Huawei’s European policy dated 19 May 2026 makes the later S0 warranty years dependent on connection to FusionSolar SmartPVMS, with the sales contract controlling the cover.

The S0 power and battery modules appear in Huawei’s 2024 UK PSTI (Product Security and Telecommunications Infrastructure) statement. Its separate period concerns product security rather than hardware warranty. Huawei continues to publish the S0 product and support pages, although current UK new supply for every component remains unconfirmed.
