Overview

The HJLX-AC photovoltaic AC combiner box is an important component suitable for string power generation systems in photovoltaic string power generation systems, supporting string inverters and AC distribution cabinets or step-up transformers. The incoming line of this combiner box uses circuit breaker input, and the output uses circuit breakers or load isolating switches. After busbar convergence, it uses secondary lightning protection. The system's rated voltage is AC690V. The protection level is IP65, the same as string inverters, meeting outdoor installation requirements and meeting waterproof, dustproof, UV-resistant, and salt spray corrosion resistance.

This product greatly simplifies wiring between string inverters and AC distribution cabinets or step-up transformers. The internal structure is clean and clear, with neat, reasonable wiring. High reliability and easy maintenance. Outdoor wall-mounted installation can adapt to various harsh environments. In addition to standard materials and dimensions, customization is available according to user requirements.

Electrical technical parameters

Functional features

AC combiner box protection rating reaches IP65, meeting outdoor installation requirements for wall-mounted sealed cabinets:

Supports simultaneous connection of multiple group inverters, each incoming line protected by a thermomagnetic circuit breaker, rated voltage up to AC690V:

Using a dedicated high-voltage lightning protector can meet the requirements for overvoltage and lightning protection between three phases, with an operating voltage of AC480V or above:

All busbars inside the box are connected using electroplated or purified busbars to reduce internal resistance and connection points;

The output uses a circuit breaker, load isolator switch, or fuse.
