Affordable
Our Modular Power Kit offers exceptional value, priced at less than $450 per kilowatt-hour (USD). This is based on a 20kWh, 10kW split-phase version, ensuring cost-effectiveness for your energy needs.
48V system, lower current, lower loss, safer operation
Modular Power Kits provide a safe and low power loss 48V power solution for your application. A 48V system delivers equivalent power output while significantly reducing heat and power loss compared to 12V systems, as only a quarter of the electric current flows through the wires.
