Frequently asked questions

Yes, we have local warehouses in Africa and a dedicated technical team based in Nigeria responsible for on-site deployment.
Standard models can be delivered within 3-5 days, significantly shortening project timelines. We also provide on-site installation support and technical services to ensure smooth project implementation.

45-day delivery + Full-scope EPC (Note: This seems very optimistic for large projects; the previous answer mentioned 7-21 days for systems, which might be more accurate, or this could refer to a specific standard product. You might want to verify the intended timeframe.)
We offer full Engineering, Procurement, and Construction (EPC) services.

We exclusively use top-grade (Grade A) LiFePO4 cells supplied by a Fortune China 500 company, ensuring consistent quality, stable supply, and reliable performance.
Core advantages include:
• 6000+ cycle life (at 80% Depth of Discharge)
• Over 10 years of operation in typical solar-storage projects
• Wide operating temperature range: -30°C ~ +65°C
• Built-in smart BMS with multiple protections (over-voltage, over-current, over-temperature, etc.)
• International safety certifications: UN38.3 / IEC62619 / MSDS, etc.
Our products are widely used in various extreme environments globally, such as deserts, tropical rainforests, and coastal areas, with proven stable performance and broad recognition.

All-inclusive Logistics + Local Compliance Documentation
We partner with DHL and Maersk to provide CIF quotes and "door-to-door" all-inclusive logistics services (including prepaid duties). Average logistics time is 12 days. We can provide customs clearance documents in French / Swahili to mitigate local operational risks.

We design tailored solutions based on your location's solar irradiance, energy consumption patterns, and project scale to ensure the most cost-effective configuration.
If you are planning a project, please feel free to contact us. We will help you design a system that meets your budget and performance goals.

Fastest 72-hour response
Standardized containerized energy storage systems can be dispatched within 7 days. Customized systems (e.g., with PV linkage) are delivered within 21 days. We flexibly meet customer timing requirements.

Multi-Energy Compatibility + Intelligent Regulation
Our system supports the integration of complementary energy sources including PV solar, wind, diesel generators, and energy storage. It is equipped with an intelligent Energy Management System (EMS) that automatically adjusts the power supply strategy based on diurnal temperature variations and wind fluctuations, ensuring stable electricity supply in off-grid areas.

Low-Maintenance Design + Free Service
The system features an IP68-rated protective enclosure and intelligent self-cleaning functions (e.g., automatic dust-removal fans). Field tests in Sub-Saharan regions show a 60% reduction in maintenance frequency compared to traditional solutions. Furthermore, we offer 5 years of free basic maintenance service, significantly reducing customer operational costs.

Strong Environmental Adaptability
We utilize high-temperature resistant cells (operating temperature range: -20°C ~ +55°C) and a fully sealed design resistant to salt spray corrosion.

Answer:
• Use batteries equipped with a certified Battery Management System (BMS) featuring over-voltage, over-current, and thermal protection
• Avoid self-welding or mixing batteries from different brands
• Keep batteries away from flammable materials
• Store between 10–35°C, especially in tropical regions
