Solar Power System & BESS Resources

Key specifications, certifications and warranty terms for our commercial solar power systems and battery energy storage — the same data our engineers use to size your project. Full datasheets and catalogs available on request.

BESS Series: 50kWh – 2MWh (2026 Reference Pricing)

Factory-direct LFP storage, CIF Lagos indicative pricing. Every system ships after a 72-hour burn-in test, BMS calibration and grid-synchronization test. Excludes import duty (5–7%), VAT and local installation.

Factory-direct LFP cabinets price at $95–120/kWh (100kWh scale, FOB China) — down from $200–300/kWh three years ago. Liquid cooling standard above 100kWh; cell temperature spread held within 2°C.

Reference Design: 100kW Off-Grid Solar Power Plant

A complete, factory pre-assembled 100kW off-grid system — the configuration behind our Sudan wastewater plant and similar industrial projects. Plug-and-play on site: only cabling remains.
