Graphene: the energy of the future, today.
Our high‑density graphene battery delivers unmatched performance versus traditional lithium: 100% depth of discharge, 500,000 cycles, and up to 25 years of life. It withstands extreme temperatures, shocks and vibration with no loss of capacity.
8 kWh — real and always usable
100% DOD (Depth of Discharge)
Up to 500,000 charge cycles
Operating range: –30°C to +70°C
Smart BMS and digital monitoring
Interfaces: Wi‑Fi / CAN / OLED display
Galvanized, powder‑coated steel structure
No thermal runaway or explosion risk
Graphene vs Lithium: the real difference
More cycles, more energy, more freedom.
Traditional lithium lets you use only part of the capacity and usually recharge once a day. With Super Barrel Graphene, you can discharge 100% and recharge up to 5 times per day with no performance loss.
Result: up to +470% more available energy every day, with zero degradation.
The brain of the system: power and intelligence in one.
The integrated inverter manages energy from PV, battery and grid/generator at the same time, optimizing flows in real‑time for maximum autonomy and safety.
