Application — Defense equipment power
Requirement — The customer needed a power source for defense equipment power with AC220V mains power.
Solution — We combined an AC220V 8kW inverter into a LiFePO4 16S pack (DC 51.2V, 9,830Wh) as a single unit.
Result — The integrated build in an approx. 125kg housing met the defense equipment power specification.
If you are considering a custom build to a similar specification, submit a requirements sheet. Our engineer will review it and respond.
