WHAT THE SYSTEM INCLUDES

One coordinated scope.

Every proposal names each component and its role in the complete system.

Rack-mounted LFP modules with busbar inside the 209kWh storage system

Component	Details
Battery modules + BMS	LFP rack modules totalling 209kWh, with cell-level monitoring and protection
PCS / hybrid inverter	100kW bidirectional conversion, grid-tied and off-grid operating modes
Thermal management	Cabinet HVAC sized for tropical installation environments
EMS + protection	Operating schedules, remote monitoring, breakers, SPD and fire detection
PV integration	DC or AC-coupled solar input, configured per project

209kWh carries a 100kW load for about 3.8 hours at 50% utilisation
Modular — parallel cabinets scale to MWh-class storage
Factory pre-tested as a complete system before shipment
Diesel-generator coordination for long outages

What a 100kW BESS Can Power

A factory or processing plant covering two evening shifts
A hotel or resort with pool, kitchen and laundry loads
A cold-storage or water-treatment plant
A commercial microgrid with firm capacity requirements

What a 209kWh BESS can power

Usable energy of about 188kWh covers the critical loads of a mid-size facility through a typical outage window: refrigeration, lighting, IT, security and selected production circuits. At half its rated power the system runs for roughly 3.8 hours between charges.

Paired with solar, the battery shifts daytime generation into the evening peak and keeps critical circuits alive when the grid fails.

How to size storage for your site

Start from the critical load list (kW) and the hours of cover you need — not from the total site load. Energy (kWh) = critical kW × hours, adjusted for depth of discharge and reserve. Our team sizes the battery, PCS and protection against your outage pattern and tariff.

PRICE & PAYBACK

What drives the price and the payback.

Industry-typical figures for budget planning. A firm price follows the confirmed bill of materials and destination.

Cost factor	Typical figure (2026)
Solar modules	$0.28–0.48 per watt FOB, tier-1 supply
Sea freight & landed cost	Typically +20–35% over FOB to West Africa / Southeast Asia ports
Storage share	35–50% of total system cost where batteries are included
Payback	3–5 years against grid power; under 18 months when replacing diesel

Reference figures, not an offer. Tariff structure, demand charges, roof condition and destination change every project. Product photographs show factory kit configurations; final equipment appearance, rating, labelling and packing follow the ordered model.

TECHNICAL FAQ

Product FAQ

These answers describe system selection. Final equipment and compliance depend on the agreed model and destination.

What is the difference between kW and kWh in a BESS?

kW is how much power the system can deliver at one moment; kWh is how long it can sustain a load. Both are sized against your critical loads.

Can this BESS be added to an existing solar system?

Usually yes — AC-coupled integration works with most existing PV. The inverter, switchgear and control interfaces are reviewed in engineering before we confirm.

Which certificates apply for import?

Documentation follows the exact battery and PCS models — typically CE, IEC 62619, UN38.3 and MSDS. Confirm destination requirements with us before ordering.
