ZYBWX PV confluence grid box Overview

Short Description:

The ZYBWX PV AC confluence box is an important part of the series inverter and AC distribution cabinet or booster transformer, which adopts circuit breaker input, circuit breaker or load isolating switch, two-stage lightning protection after bus confluence. The rated voltage of the system is the highest AC690V. protection grade and the same stage of the series inverter IP65. meet the requirements of outdoor installation. This product greatly simplifies the connection between the group series inverter and the AC distribution cabinet or the booster transformer. The internal structure of this product is simple and clear, and the wiring is neat and reasonable. high reliability and simple maintenance. Outdoor wall mounted installation, can adapt to all kinds of harsh environment. In addition to standard material and size, can be customized according to user requirements.

 Functional characteristics

♦ The protection grade of the AC junction box reaches IP65, and the wall-mounted sealed cabinet that can meet the requirements of outdoor installation:
♦ Satisfy the simultaneous access to multiple-channel group-type inverters, each incoming line is protected by a thermal magnetic circuit breaker, and the rated voltage reaches AC690V:
♦ The use of a special high-voltage lightning protector can meet the overvoltage and lightning protection between three phases , The working voltage reaches above AC480V:
♦ The busbars in the box are all connected by electroplated or purified busbars to reduce the internal resistance and connection points of the busbars;
♦ The transmission line uses circuit breakers, load disconnectors or fuses.
