Product details
■ Product Overview
The photovoltaic grid-connected cabinet is suitable for AC 50Hz, rated operating voltage 380V, and rated operating current 2000A distribution systems for power users such as ground centralized, ground string, and ground distributed power generation. It is used for the conversion, distribution, and control of electric energy for power, lighting, and distribution equipment.
The product features high breaking capacity, good thermal stability, flexible electrical schemes, convenient combination, strong practicality, novel structure, and high protection grade. It can be used as a replacement product for low-voltage complete switchgear equipment.
■ Normal Operating Environment
◇ Ambient air temperature not higher than +40°C and not lower than -5°C. The average temperature within 24 hours must not exceed +35°C.
◇ Indoor installation; the altitude of the installation site must not exceed 2000m.
◇ Relative humidity of the ambient air does not exceed 50% at the highest temperature of +40°C, and higher relative humidity is allowed at lower temperatures (e.g., 90% at +20°C). Consideration should be given to the possibility of condensation due to temperature changes.
◇ The inclination of the equipment installation relative to the vertical plane does not exceed 5°.
◇ The equipment should be installed in places free from severe vibration and impact, as well as places where electrical components are not subject to corrosion.
◇ Special requirements from users shall be resolved through consultation with the manufacturer.
