105 KW AC to DC Bidirectional Converter On-grid and Off-grid Type for Energy Storage System
NESI-105 KW AC to DC Bidirectional Converter On-grid and Off-grid Type for Energy Storage System
Product Overview
The 105kW on-grid and off-grid group series type energy storage converter is a single branch standard rack type product. It can be used in a variety of grid-connected and off-grid application scenarios, such as emergency power backup, mobile energy storage, transformer capacity expansion in platform area, peak-load shifting, or dynamic capacity increase, etc. At the same time, it can rapidly expand capacity according to user requirements, and conveniently realize the parallel networking of multiple devices to form a small and medium-sized energy storage system. Can be used independently off-grid, with strong load applicability; the power grid has strong adaptability and excellent usability; Easy integration, single module and a cluster of conventional standard batteries on the market to form a standardized 0.5C energy storage system, to achieve fine management of batteries.
Features
Convenient multi-equipment grid connection; The multi-branch high-power energy storage system can be formed by multiple PCS in parallel.
The standard rack design can be perfectly combined with the lithium battery cabinet to form a distributed energy storage cabinet.
High power density, small size, easy handling, two people can be installed by hand
Three level design, low harmonics, good power quality.
Can be off-grid use, independent inverter for load.
