17 years of focus on industrial and commercial solar energy system solutions - providing all-round protection for your investment
In terms of system durability, we provide you with industry-leading reliability through top-level configuration and rigorous testing of the entire industry chain:
1. Military-grade standards for core components
Photovoltaic components: using LONGi high-purity monocrystalline silicon wafers, attenuation ≤2% in the first year, 30-year linear power output guarantee
Inverter system: equipped with German Siemens IGBT modules and isolation transformer design, the surge resistance is increased by 300% compared with the transformerless solution, and the MTBF (mean time between failures) of the whole machine exceeds 100,000 hours.
For other similar designs, we are intelligent high-end design, providing 5 years of free predictive maintenance services to save operation and maintenance costs.
2. Smart energy storage safety system
Lithium battery pack: EVE original A-grade battery cell (UL1973 certification documents available), equipped with three-level BMS management system and V0-level fireproof packaging, cycle life of 6000 times @80% DoD
Full-link traceability: S/N code can be traced from battery cell batch to system integration
3. Extreme environment verification
Passed 100+ stress tests of CNAS certified laboratory, including:
Continuous full load operation at 45℃ for 2000 hours
Grid voltage fluctuation ±25% adaptability test
Simulated salt spray/sand and dust and other harsh environment accelerated aging experiments
4. African localized service network
63 certified engineers covering West/East/Southern Africa (hub cities such as Lagos, Nigeria, Nairobi, Kenya, and Johannesburg, South Africa)
Provide 7×24h remote diagnosis + 72-hour on-site response service
Customer-exclusive operation and maintenance training system (including PVsyst simulation report interpretation)
Our system is designed to last for 10 years, and key components are provided with 5-year full warranty + 10-y
The King of the Democratic Republic of the Congo has provided a solar energy storage power station system for the village of Bunkeya to meet the electricity needs of 2500 small households in the village. As the village currently lacks access to the grid, the King requested the design of a 1MW solar panel system paired with a 1.8MWh lithium battery storage system to power the entire village.
