Overview

This product is mainly applied in 100kW~2000kW high-power industrial and commercial photovoltaic grid-connected power generation systems. It is connected in series between the grid-connected inverter (or AC combiner box) and the power grid. The product is equipped with a series of protection functions, including anti-islanding protection, closing under voltage presence, tripping under voltage loss, grid undervoltage, grid overvoltage, input lightning protection, system overcurrent, and grid isolation. The multifunctional electricity meter display and fault status indication make the system's operating status clear at a glance. The product has passed industry-standard certifications such as CCC, CE, and ISO9001 quality management system certification.

Main Features

Reserves installation positions for metering electricity meters and collectors; the metering meter is equipped with a visible window and lead-sealed port (to prevent electricity theft).
The product adopts an integrated design concept: the power distribution part and metering part are completely isolated to reduce electromagnetic interference.
It is equipped with photovoltaic-specific molded-case recloser circuit breakers and 万能 frame circuit breakers (optional), ensuring more reliable performance.
It can be matched with supporting devices such as online power quality monitoring, anti-islanding protection devices, and fault splitting devices.
Both outdoor and indoor installation options are available for greater convenience. Special requirements and function customization are supported.
