Storepower MACH3 is a high performance and efficient mechanical battery that can store electrical energy as kinetic energy and convert it back into electrical energy when needed. With a storage cycle of up to 24 hours and instantaneous power delivery, this is the ideal solution for applications that require fast and stable energy supply.
Single flywheel can store 6kWh
50kW operational and 200kW peak
Charging and discharging in seconds
30 years with almost no efficiency loss
The MACH3 flywheel energy storage is based on a purely mechanical principle. For charging, its rotor is accelerated up to very high speeds and electricity is stored in the form of kinetic energy. When discharging, the motor acts as a generator to convert the spinning motion back into electricity.
The first-generation flywheels were developed in the last century, they had a massive steel disk that rotated at a low speed. Since kinetic energy equals mass times speed squared, doubling the mass doubles the energy storage capacity, and doubling the rotational speed quadruples the capacity. Based on this physical principle, we designed the rotor of MACH3 flywheel made of innovative carbon fiber composite material, allowing it to spin at an impressive 50 000 rpm, providing maximum energy density and operational safety.
Our special magnetic levitation system allows our flywheel to spin in vacuum without friction or aerodynamic drag. High tech magnetic bearings and for some applications – lifting magnets prevent flywheel from mechanical failures, reduce heat generation and energy losses. Magnetic levitation protects flywheel from frequent maintenances and downtime issues while extending flywheel life, which can reach 30 years.
While monofacial solar panels have an opaque back sheet and can only absorb sunlight from the front of the panel, bifacial solar modules have a transparent back plate. This allows the double-sided solar panels to capture sunlight from both sides, producing more energy and delivering higher efficiency. The back of the panel can also absorb reflected sunlight; therefore, most often they are installed on special mounting systems over reflective surfaces.
