Introduction
This product is primarily designed for high-power commercial and industrial photovoltaic grid-connected power generation systems ranging from 100 kW to 2,000 kW. It is connected in series between the grid-tie inverter (or AC combiner box) and the utility grid. The product features a range of protective functions, including anti-islanding protection, voltage-sensing closing, undervoltage tripping, low-voltage detection on the grid, overvoltage protection, input surge protection, system overcurrent protection, and grid isolation. A multi-function meter provides clear display of operational status and fault indications, making the system’s operating condition immediately apparent. The product has obtained industry-standard certifications such as CCC certification, CE certification, and ISO9001 quality management system certification.
Product Details
Main features
Reserved installation locations for metering electricity meters and data collectors; visible windows on the metering electricity meters and lead seals (anti-theft features); an integrated design concept for the product, with complete electrical isolation between the distribution and metering sections to reduce electromagnetic interference; photovoltaic-specific molded-case reclosable circuit breakers and universal frame circuit breakers (optional), offering even more reliable performance; compatible with online power quality monitoring systems, anti-islanding protection devices, fault separation devices, and other related equipment; available for both outdoor and indoor installation, making installation more convenient.
Supports special requirements and custom feature development.
