Application — ESS and high-capacity power supply
Requirement — The challenge was to handle AC220V mains power and real-time status monitoring within one pack in the ESS and high-capacity power supply system.
Solution — We built an AC220V 5kW inverter and RS485 communication monitoring into a LiFePO4 16S pack (DC 51.2V, 10,485Wh).
Result — The integrated build in an approx. 130kg 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.
