MacroCaps supercapacitors are engineered for applications where standard batteries are too slow, too large, or too costly to maintain. Each unit starts at 2.7V / 25,000F and can be combined — in series or parallel — inside modular rack and cabinet systems, available in indoor, outdoor, and containerized formats (10′, 20′, 40′).
Every MacroCap unit carries its own integrated balancing card, continuously reporting unit ID, temperature, internal pressure, and voltage to the control system. For engineering teams, this means cell-level diagnostics without external monitoring hardware. For operations teams, it means predictive maintenance instead of reactive failure response — lowering unplanned downtime and service costs.
Units connect without inter-cell cabling, at both the cell level (via the balancing card) and the rack level (series/parallel configuration). Fewer connections mean fewer failure points and a shorter, less error-prone install. On the business side, this translates directly into lower installation labor cost, faster commissioning timelines, and reduced spare-parts inventory — since there are simply fewer discrete components to stock and replace.
The compact, cable-free footprint delivers meaningful space savings in installations where real estate or enclosure size is constrained — a direct capex benefit in retrofit and urban-siting projects. Fewer components also means a shorter bill of materials and simpler procurement, reducing both upfront cost and long-term maintenance overhead.
We are at the forefront of the energy storage industry, offering supercapacitor systems that redefine energy storage capabilities by providing extremely high rates of capacitance.
The World’s most Powerful Supercapacitors and Systems
Since 2016, we have successfully developed and introduced our groundbreaking patented architecture for the world’s most powerful capacitor systems. This innovative system utilizes a single series of the most potent double-layer capacitors ever manufactured.
The single-series configuration can be flexibly arranged in parallel and/or into a series providing an even greater capacity for energy storage. The power delivery of this system is only limited by the power and quantity of deployed inverters.
With an ultra-low Equivalent Serial Resistance (ESR), the MacroCap eliminates the need for additional cooling mechanisms for the capacitors themselves. Currently recognized as the most powerful electrical capacitor in production, the Macro Capacitor is manufactured from inert materials, ensuring environmental safety.
Setting a new standard, it is the first capacitor system to incorporate built-in CPU-controlled active balancing and voltage protection, making it a revolutionary choice in the market.
MacroCaps’ supercapacitor propels the expansion of the grid and the development of various types of energy sources, smoothing out energy fluctuations and ensuring grid stability with immediate response. MacroCaps technology is engineered to deliver megawatts of energy in milliseconds.
