Expand your Energy Storage up to 27.6 kWh
Start with the Barrel Core Unit, which includes 4.8 kWh of LiFePO4 battery storage. Need more power? Easily expand your storage by adding up to 3 Barrel Storage Units (7.6 kWh each).
✅ 4.8 kWh (Core Unit) + (7.6 kWh × 3) = 27.6 kWh
✅ More autonomy, fewer generator hours, lower fuel costs
✅ Long-lasting LiFePO4 technology with over 6,000 cycles
Parallel Connection scale up to 30 kW & 36 kWp Solar
Need more power? Connect up to 5 Barrel Core Units in parallel for high-demand applications.
✅ 5 × 6 kW = 30 kW of AC power
✅ Up to 36 kWp of solar capacity
✅ Perfect for refugee camps, field hospitals, and remote industries
Three-Phase Setup up to 18 kW Inverter & 18 kWp Solar
For industrial or high-power applications, connect 3 Barrels in series to enable a three-phase energy system.
✅ 3 × 6 kW = 18 kW (Three-Phase Power)
✅ Up to 18 kWp of solar capacity
✅ Runs industrial machines, water pumps, and refrigeration systems
Hybrid mode: Barrel + Diesel Generator
Barrel integrates seamlessly with a diesel generator via its On/Off dry contact control.
✅ Automatically turns the generator on/off based on battery charge
