5MWh C&I Solar-Storage-Diesel Microgrid Project at a Copper-Cobalt Mine, Democratic Republic of the Congo
An LVK 5MWh heavy-duty liquid-cooled BESS container with industrial-grade hybrid inverter cluster and 3.5MWp ground-mounted PV at a remote DRC copper-cobalt mine — LVK's largest-capacity African flagship project.
Project Overview
Project Background
An LVK 5MWh heavy-duty liquid-cooled BESS container with industrial-grade hybrid inverter cluster and 3.5MWp ground-mounted PV at a remote DRC copper-cobalt mine — LVK's largest-capacity African flagship project.
Customer Needs
Situated deep in the African interior and completely off-grid, the mine previously relied entirely on diesel generators for power. Recent production expansions, including the introduction of massive electric shovels and charging stations for haul trucks, pushed daily diesel consumption to tens of thousands of liters, resulting in exorbitant long-distance fuel transport costs and significant safety risks. Furthermore, the frequent starting and stopping of heavy mining equipment caused massive instantaneous power surges, leading to frequent outages.
Application Focus
C&I Solar-Storage-Diesel Off-Grid Microgrid
Solution Design
Integrated ESS Design For Site Operations
The project deploys a standard 5MWh outdoor liquid-cooled energy storage container. The core power distribution architecture utilizes a cluster of industrial-grade, high-power hybrid inverters connected in parallel, managed by a large-scale, intelligent EMS scheduling network designed for mining operations, creating a heavy-industry off-grid microgrid.

Results & Benefits
Project Outcomes
Successfully reduced the mine's annual diesel consumption by 48%, resulting in significant savings on procurement costs.
Significantly improved power grid quality at the site, completely eliminating frequent power outages caused by the starting and stopping of heavy machinery, thereby ensuring stable production expansion.
Utilized a highly integrated hybrid inverter cluster to simplify power distribution; maintenance costs were reduced by 25%, and the projected payback period (ROI) is just 2.6 years.
