Application — Special-purpose vehicle power
Requirement — The challenge was to handle AC220V mains power within one pack in the special-purpose vehicle power application.
Solution — We built an AC220V 8kW inverter into a LiFePO4 16S pack (DC 51.2V, 8,601Wh).
Result — The integrated build in an approx. 120kg housing met the special-purpose vehicle power specification.
If you are considering a custom build to a similar specification, submit a requirements sheet. Our engineer will review it and respond.
