What MG Energy Systems does
MG Energy Systems B.V. is a privately held Dutch designer and manufacturer of modular lithium-ion battery systems headquartered in Leeuwarden, Netherlands, founded in 2009. The company builds battery modules in both LiFePO4 (LFP, used for inherently safer and regulation-friendly applications) and NMC (used for high energy-density applications, ~159–182 Wh/kg in the HE Series), along with in-house Battery Management Systems (Master LV for ≤144 V systems and Master HV for higher-voltage systems up to 900 Vdc), a SmartLink MX combiner for parallel/redundant configurations, an AFC 300 alternator regulator, and a monitoring/control stack comprising the Energy Monitor display, Connect App, and Energy Portal. Architecture is modular and scalable from 12 V modules to 900 Vdc systems and from compact recreational installations to multi-megawatt industrial storage (10 kWh–2 MWh).
The company's commercial focus is maritime (recreational, superyacht, commercial ferry, and inland shipping), with secondary verticals in vehicles (commercial, emergency, recreational), industrial machinery (peak shaving, UPS, construction, agriculture), and off-grid/on-grid solar storage. The Marine segment is primary and is supported by Lloyd's Type Approval on the RS 230 Marine Battery (2025), ES-Trin/IEC-EN 62619 & IEC-EN 62620 compliance for inland vessels, SIL-2 functional safety certification, and UN38.3 transportation compliance. The business model is B2B hardware sales combined with project-based engineering services: enterprise customers submit system requests and receive custom propositions (system capacity, voltage, charge/discharge profiles), while smaller buyers are routed to a worldwide MG Points dealer network. Pricing is not publicly disclosed; revenue is generated through one-time hardware purchases across battery modules, BMS units, monitoring products, and accessories. There are no disclosed funding rounds, no institutional investors, and no parent company; ownership appears founder-led, with co-founder/director Gerard van der Schaar identified in company imagery.
