Product Overview
The SHLX Photovoltaic Grid-Connected Box is a crucial power protection component for photovoltaic string inverter systems, connecting string inverters to the grid system. It features circuit protection with photovoltaic grid-connected circuit breakers and pull-ring type isolating switches, along with a second-level lightning protection, rated at the same level as the string inverters at 65, meeting outdoor installation requirements, and providing protection against ultraviolet rays, salt mist corrosion, and more. The internal structure of this product is simple and clear, with neat and reasonable wiring. It boasts high reliability and easy maintenance. It is designed for outdoor wall-mounted installation and can withstand various harsh environments. In addition to standard materials and dimensions, it can be customized according to customer requirements. The SHLX-AC Photovoltaic AC Collector Box is an essential component for photovoltaic string inverter systems, connecting string inverters to AC distribution cabinets or step-up transformers. This collector box uses circuit breakers for input and circuit breakers or load isolating switches for output, with busbars.
The system employs a secondary lightning protection, with a rated voltage of up to AC690V. The protection grade is equal to that of string inverters at 65, meeting outdoor installation requirements, including UV resistance and corrosion resistance against salt spray.

It boasts high reliability and easy maintenance. It is suitable for outdoor wall-mounted installation and can withstand various harsh environments. In addition to standard materials and dimensions,
Available for customization to meet customer requirements.
Electrical Technical Specifications

Features● The junction box has a protection grade of 65, meeting the requirements for outdoor installation and wall-mounted, sealed cabinets.
● Suitable for simultaneous connection of multiple string inverters, each input line is protected by a thermal magnetic circuit breaker, with a rated voltage of AC690V.
● Utilizes a dedicated high-voltage surge protector to ensure overvoltage and lightning protection between three phases; operating voltage reaches above AC480V.
● The busbars inside the cabinet are all connected with electroplated or purified busbars, reducing the internal resistance of the busbars and the connection points.
Output uses circuit breakers, load isolating switches, or fuses.
