Taiwan 3.132 MWh / 1.5 MW Grid-Connected BESS

A grid-connected battery energy storage system in Taiwan

Project Overview

A 3.132 MWh / 1.5 MW grid-connected BESS in Taiwan, composed of six ~522 kWh / 250 kW liquid-cooled storage units with integrated combiner / control cabinets and related ESTS / UPS functions, unified by a self-developed EMS.
