Energy Projects Lose Money in Three Familiar Ways
Curtailment Wastes Your Renewable Investment
Solar and wind farms export power when prices are lowest and get curtailed when the grid is full. Storage shifts that energy into the hours that actually pay.
Weak Grids and Diesel Burn Cash Every Day
Unstable grids, capacity limits and diesel generation eat project margins. A containerized BESS replaces fuel costs with stored, dispatchable energy.
Utility Projects Can’t Afford Slow Deployment
Site-built systems tie up capital for months. Pre-integrated, factory-tested containers cut on-site work to foundations, craning and grid connection.
Four Proven Revenue Scenarios
Renewable Integration & Energy Shifting
Absorb midday solar and off-peak wind, dispatch into evening peaks. Pairing storage with generation turns intermittent output into firm, sellable capacity.
Frequency Regulation & Grid Services
Liquid-cooled power stages respond in milliseconds, delivering the fast, precise output that frequency regulation and ancillary-service markets pay for.
Microgrids, Islands & Diesel Replacement
Anchor a solar-plus-storage microgrid and run diesel only as a last resort. The fuel-price spread between diesel and stored solar is the business case.
Mining, Farms & Weak-Grid Sites
Where grid connection is limited or unreliable, containers deliver firm power without waiting years for network upgrades — and scale as operations grow.
Which Container Fits Your Project?
| Your Project | Recommended System | Capacity | |
|---|---|---|---|
| C&I sites, microgrids and mid-scale projects up to ~5 MWh | 20FT Container BESS | 3.44 / 5.015 MWh per unit (two models) | View Details → |
| Utility-scale, grid-side and large renewable plants | 40FT Container BESS | 7.53 MWh per unit, 1500V platform | View Details → |
| Multi-hundred-MWh to GWh-scale plants | Multi-Unit Block + PCS/MV Skid | Parallel container blocks with integrated PCS & MV step-up | Talk to Engineering → |
Proven in the Field
Lagos 1MW Solar Microgrid Project ▶ VIDEO
A 20FT container with 1MW PCS and 1MWh LFP storage powers a commercial facility in Lagos, replacing diesel generation with solar-plus-storage through daily grid outages.
Mombasa 5MWh Container Delivery & Installation ▶ VIDEO
Crane lift and positioning of a 20FT 5MWh liquid-cooled container at an industrial site in Mombasa — from truck to energized in a single working day.
Baghdad Container Site Installation
A 20FT liquid-cooled container set on a concrete pad outside Baghdad, pre-commissioned on site by Marwell engineers before final grid connection.
Kindia 16MW+32MWh Solar-Storage Plant ▶ VIDEO
Sixteen 40FT liquid-cooled containers form a 16MW/32MWh storage plant paired with a ground-mount solar farm in Kindia — the largest battery storage project in the region.
Riyadh Desert-Climate Storage Project ▶ VIDEO
Two 40FT liquid-cooled containers run through 50°C desert summers outside Riyadh, firming a commercial solar plant with reliable backup when needed.
Atacama Utility-Scale Container Fleet
Rows of 40FT containers beside a substation in the Atacama Desert shift one of the world’s strongest solar resources into the evening peak.
A Delivery Process Built for EPC Timelines
1 · System Design
Share your site layout, grid requirements and dispatch profile — our engineers return a sized configuration with single-line diagram and layout proposal.
2 · Factory Acceptance Test
Every container is fully assembled and put through a complete FAT before shipment — racks, BMS, PCS, cooling and fire systems verified as one unit.
3 · Shipped & Set in Place
Standard ISO-footprint containers move by sea, road and crane like any cargo. On site: foundation, lift, connect, commission.
4 · Monitored & Supported
Integrated monitoring with remote diagnostics comes standard, plus engineering support from commissioning through operation.
