Description

⚡ BAC300100 / BAC75040 Series

15kW – 20kW PCS Energy Storage Converter
AC/DC Bidirectional Power Module

The most distinctive feature of this energy storage converter is its low voltage and high current. It can support a minimum voltage of 40V and has an output rated current of 100A. It is widely applied in many fields such as photovoltaic storage and charging, charging and discharge, emergency disaster relief power supply and equipment aging, and is the first choice for industries that require bidirectional energy flow.

🔁 Full Bidirectional Energy Flow
⚙️ High-Frequency Isolation
📦 Hot-swappable & Parallel
