10MWh Container + 9.6MW PV – What Happens When Congo Meets SUNDTA?

A technical delegation from a Congolese energy enterprise has arrived in China for a week-long visit to SUNDTA’s headquarters and manufacturing facilities. The visit focuses on inspecting a 9.6MW photovoltaic (PV) system, a 2.4MW power conversion system (PCS), and a 10MWh battery energy storage container, which together form a comprehensive utility-scale energy storage solution tailored for the customer’s solar-plus-storage project in the Democratic Republic of the Congo.

During the visit, Congolese engineers and project managers engaged in in-depth discussions with SUNDTA’s technical team regarding the integration of the 9.6MW PV array with the accompanying 2.4MW PCS. The 10MWh containerized lithium-ion battery system was demonstrated as a critical component for peak shaving, load shifting, and backup power in regions with unstable grid infrastructure. The delegation also toured SUNDTA’s production lines for lithium iron phosphate (LFP) batteries, modular DC-coupled storage units, and smart energy management systems (EMS).

A highlight of the collaboration is SUNDTA’s deep strategic partnership with Solis, a global leader in inverter technology. Under this alliance, Solis provides comprehensive technical support for energy storage inverters, including hybrid inverters, low-voltage battery-ready inverters, and high-voltage three-phase inverters. The compatibility between Solis energy storage inverters and SUNDTA’s lithium batteries ensures stable and safe power generation, with features such as state-of-charge (SoC) balancing, overcharge protection, and thermal runaway prevention.

The visit also covered contractual details for the procurement of the 9.6MW system, including on-grid and off-grid switching capabilities, frequency regulation, and islanding detection. The Congolese customer emphasized the need for scalable battery modules and remote monitoring via cloud-based EMS. SUNDTA responded by presenting its latest liquid-cooled battery racks, which enhance cycle life and round-trip efficiency (RTE) in tropical climates.

The two parties signed a memorandum of understanding (MoU) to advance the project, with SUNDTA committed to delivering the complete solution within six months. The cooperation is expected to bolster renewable energy penetration in Central Africa, reduce diesel generator dependency, and support mining operations with reliable solar-storage hybrid power.

This visit marks a milestone for SUNDTA’s expansion into African off-grid and weak-grid markets, leveraging Solis’s grid-forming inverters and SUNDTA’s high-density energy storage systems to enable 24/7 clean electricity.
