What Top Systems does
Top Systems B.V. is a Netherlands-based specialist in DC energy systems, battery storage, and off-grid power solutions, founded in 1985 and operating with 39 employees. The company is the world's largest distributor of Victron Energy products and sells its own proprietary product lines, including the TopSmart ESS (an energy storage system) and Li-Swap technology. It serves a broad customer base spanning automotive, maritime, construction, defense, telecom, and industrial applications, with cumulative deliveries reported at 104,001 MW and 136,412 MWh across 9,235 projects and 34,332 customers. The business model combines third-party hardware distribution (Victron-centric), proprietary branded product sales, project-based integration services, system design and consulting, training through an internal knowledge center, and recurring maintenance contracts.
The company's go-to-market relies on a multi-vendor integration stack: it pairs the Victron core line with adjacent offerings from MG Energy, Pylontech, SBR, and OSM Systems, and in April 2024 added a strategic partnership with Hybrid Power Units (alongside a Holland Capital PE investment) to address larger turnkey projects. The October 2024 acquisition of SmartGrid extends capability further into integrated, larger-scale energy installations. Customer references include Mercedes-Benz, Boeing, Airbus, KLM, and TomTom alongside named automotive, maritime, and construction end-users, indicating technical credibility with demanding enterprise buyers.
Revenue mechanics span distribution margins on third-party hardware, value capture on proprietary TopSmart ESS and Li-Swap products, integration and engineering fees on project work, and recurring revenue from training programs and maintenance contracts. The company is privately held and does not disclose revenue; its long-standing Victron relationship, multi-vendor ecosystem, and recent capital and M&A activity point to a specialist integrator model that is scaling from SMB/integrator roots into larger project deployments.

Top Systems competitors and assessment
Company assessmentDirect peers
- Alfen: Alfen is a Dutch energy solutions company offering energy storage, smart grid, and EV charging solutions across Europe. Comparable to Top Systems in target market (Benelux enterprise and utility customers), product overlap (battery storage systems), and vertical focus (energy transition), though Alfen is significantly larger and listed on Euronext Amsterdam.
- Hoppecke: Hoppecke is a German industrial battery manufacturer serving emission-free propulsion, secured power supply, renewable energy storage, and rail applications. Comparable to Top Systems in industrial and off-grid energy storage markets; Hoppecke is one of Top Systems' distributed brands for industrial battery systems.
- MG Energy Systems: MG Energy Systems manufactures high-end lithium battery systems for maritime, industrial, off-grid/solar, and automotive applications globally. Comparable product portfolio (lithium battery systems for marine/industrial) and overlapping customer base with Top Systems; Top Systems is MG's primary distributor in Benelux, and MG awarded Top Systems the 2023 Dealer Award.
- Instagrid: Instagrid designs and manufactures professional-grade portable battery systems for construction sites, events, and off-grid applications. Directly comparable niche to Top Systems' construction and mobile power solutions; Instagrid is also a Top Systems distribution partner, creating both partnership and partial competitive overlap in the mobile professional power segment.
Broad incumbents
- Sonnen (Shell): Sonnen, owned by Shell, provides residential and commercial battery storage systems in Europe with integrated virtual power plant and energy community software. Comparable to Top Systems in residential/SMB ESS market and in energy trading features, but with deeper software stack and Shell's distribution scale.
- BYD Energy Storage: BYD is a global battery and energy storage manufacturer offering commercial and utility-scale ESS products. Competes with Top Systems in C&I battery storage market with vertically integrated cell-to-system manufacturing at significant scale, though BYD does not focus on the mobile/niche maritime and construction segments that Top Systems serves.
- Victron Energy: Victron Energy is the global manufacturer of inverters, chargers, batteries, and solar charge controllers that form the technology backbone of Top Systems' offerings. As Top Systems' core supplier for 34+ years and the world's largest Victron distributor, the two companies are deeply intertwined. Victron represents both Top Systems' primary supply partner and the broader incumbent whose technology ecosystem Top Systems extends.
- Schneider Electric (Energy Storage): Schneider Electric offers commercial and industrial energy storage solutions through its EcoStruxure platform, including battery systems, microgrids, and energy management software. Overlaps with Top Systems in industrial ESS and microgrid offerings but operates at much larger scale with broader portfolio including switchgear, EV charging, and grid services.

Directly competes with Top Systems' residential/SMB TopSmart ESS and larger commercial ESS offerings, with substantially greater brand recognition, scale, and direct-to-customer sales model.
Emerging players
- BlueNova Energy: BlueNova Energy is a South African energy storage company providing lithium battery systems for residential, commercial, and industrial applications across Africa. Comparable to Top Systems in off-grid and backup power solutions for markets with unreliable grids, but focused on African geographies and not directly competing in Top Systems' Benelux core market.
