BWG Photovoltaic Grid-connected Cabinet
Picture show
Overview
The product is mainly used in 100KW ~ 2000KW high-power industrial and commercial photovoltaic grid-connected power generation system, which is connected in series between grid-connected inverter (or AC combiner box) and power grid. The product has a series of protection such as anti-islanding protection, voltage failure trip, power grid low voltage, power grid overvoltage, input lightning protection, system overcurrent, power grid isolation, etc. The multi-function meter display and fault status indication make the system running status clear at a glance, products through the industry standard CCC certification, CE certification, IS09001 quality management system certification.
Product Details
Main features
Reserve the installation location of metering meters and collectors; Metering meters can be sealed with windows and lead (anti-theft); The integrated design concept of the product, the power distribution part is completely isolated from the metering part, reducing electromagnetic interference, photovoltaic special plastic case reclosing circuit breaker and universal frame circuit breaker (optional), with more reliable performance; It can be equipped with online power quality monitoring, anti-islanding protection device, fault disconnection device, etc. Outdoor and indoor installation are optional, installation is more convenient.
Support special requirements and function customization.
