Application — ESS and high-capacity power supply
Requirement — The request was to consolidate AC220V mains power for ESS and high-capacity power supply into a single power unit.
Solution — We configured a Li-ion 14S pack (DC 50.4V, 13,600Wh) together with an AC220V 2kW inverter.
Result — The integrated build in an approx. 75kg housing met the ESS and high-capacity power supply specification.
If you are considering a custom build to a similar specification, submit a requirements sheet. Our engineer will review it and respond.
