Brunei GGD low voltage photovoltaic grid-connected cabinet
Category:
Product Description
This product is mainly used 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 has a series of protections such as anti-islanding protection, pressure closing, voltage loss tripping, grid low voltage, grid overvoltage, input lightning protection, system overcurrent, grid isolation, etc. The multi-function meter display and fault status indication make the system operation status clear at a glance. The product has passed the industry standard CCC certification, CE certification, IS09001 quality management system certification, etc.

Conditions of use
• The ambient air temperature shall not be higher than +40°C and not lower than -5%C. The average temperature within 24 hours shall not be higher than +35°C;
• For indoor installation, the altitude of the place of use shall not exceed 3000m;
• The relative humidity of the ambient air shall not exceed 50% when the maximum temperature is +40°C, and a higher relative humidity is allowed at lower temperatures. (For example, 90% at +20°C) The influence of condensation that may occur occasionally due to temperature changes should be taken into account:
• The equipment should be installed in a place without severe vibration and impact, and in a place where the electrical components are not corroded;
• If the user has special requirements, consult with the manufacturer to solve them.
Main features
Reserved installation position for metering meter and collector; metering meter with viewing window and lead seal (to prevent electricity theft); integrated design concept of the product, complete isolation of the distribution part and the metering part, reducing electromagnetic interference, photovoltaic special
molded case reclosing circuit breaker and universal frame circuit breaker (optional), more reliable performance; can be equipped with online power quality monitoring, anti-islanding protection device, fault decoupling device, etc.; outdoor and indoor installation are optional, and installation is more convenient.
