PRODUCT OVERVIEW
This product is mainly used in photovoltaic distributed grid-connected power generation system, which
is connected in series between grid-connected inverter and grid. The product has a series of
protections such as grid low voltage, grid overvoltage, input lightning protection, system overcurrent,
grid isolation, etc. Accurate electric energy metering, transmission and intelligent operation control are
essential parts of household grid-connected power generation system. The product has passed CCC
certification, CE certification, ISO9001 quality management system certification, etc.
MAIN CHARACTERISTICS:
Reserve the installation position of metering meter and collector;
Visual window and lead seal of metering meter (anti-electricity stealing);
The integrated design concept of the product, the power distribution part is completely isolated from the metering part, and the electromagnetic interference is reduced;
Special photovoltaic molded case reclosing circuit breaker, with more reliable performance;
It can be matched with on-line power quality monitoring and islanding protection device, fault
disconnection device, etc;
Optional outdoor and indoor installation, making installation more convenient;
Support special requirements and function customization.
