Belinus Energy
At a Glance
The Energy Wall G1 ships as a 16 kWh graphene supercapacitor with a listed launch and price target of Q1 2026 at €7,000 per unit. That lithium-free energy storage form factor is rare in residential offerings and signals a different lifetime and recycling profile.
Core Features
Belinus offers lithium-free, recyclable storage and high-efficiency bifacial solar panels backed by a 35-year warranty. The product family lists sodium-ion cells and graphene supercapacitors alongside modular battery cabinets for homes and industry.
The technical stack includes a centralized Energy Management System with real-time control, plus Solis inverters sized 5 to 25 kW, an ETAP Pro EV Charger for fleet use, and automated quotation software slated for January 2026.
Key Differentiator
Lithium-free, recyclable chemistry combined with Belgian engineering sets Belinus apart. Their suite pairs sodium-ion cells and graphene supercapacitors with modular cabinet design so you can scale from home storage to 400 plus kWh commercial modules without switching chemistry.
Pros
Strong sustainability focus and recyclable chemistries that reduce lithium dependence, attractive for homeowners who prioritize material circularity over conventional lithium setups.
Graphene supercapacitor option for high cycle life and fast charge discharge, useful where repeated short discharge cycles matter more than raw energy density.
Integrated ecosystem across products: Solis inverters with EMS integration, ETAP Pro EV Charger for fleet management, and a centralized EMS that supports tariff optimization and battery arbitrage.
Commercial capabilities include 400+ kWh utility modules, a target Belinus-branded PCS for CNI applications, and service offerings for energy trading and grid-integrated services.
Cons
Public technical documentation and independent third-party reviews are limited and pricing detail is patchy, which makes vendor comparison and procurement due diligence harder for buyers used to widely documented lithium systems.
Who It’s For
Environmentally conscious homeowners and industrial operators in the Benelux who want a lithium-free path to resilience. Good fit for sites where recyclability, long warranties, and multi-technology support matter more than highest energy density.
Unique Value Proposition
The lithium-free Energy Wall G1 with a 16 kWh graphene supercapacitor is the clearest signal of Belinus strategy. Pair that hardware with a centralized EMS that runs 15-minute dynamic tariff optimization, RESTful API access, and mobile plus web dashboards and you get both hardware and operational levers for savings and arbitrage.
Real World Use Case
A homeowner in the Benelux combines high-efficiency bifacial panels with an Energy Wall G1 and Solis inverter. The Belinus EMS shifts loads to low tariff windows and runs battery arbitrage while an ETAP Pro unit charges an EV fleet for a small business on site.
Pricing
Energy Wall G1 is quoted at €7,000 per unit with a Q1 2026 launch target. Broader pricing for other products is not published on the homepage, so project quotes will depend on system size, inverter choice, and commercial storage scale.
