Product Overview

SHLX PV Grid-Connected Box is a critical power protection component for photovoltaic string inverter systems, connecting string inverters to the grid system. The circuit protection section employs PV grid-connected circuit breakers and pull-ring type disconnect switches, with a two-level lightning protection, matching the 65 protection grade of string inverters, meeting outdoor installation requirements and providing UV protection, salt mist corrosion resistance, and more. The product has a simple and clear internal structure with neat and reasonable wiring. It boasts high reliability and easy maintenance. Suitable for outdoor wall-mounted installation, it can adapt to various harsh environments. In addition to standard materials and dimensions, customization according to customer requirements is available. The SHLX-AC PV AC String Box is a crucial component in photovoltaic string inverter systems, connecting string inverters to AC distribution panels or step-up transformers. This string box features circuit breaker input for the incoming lines and circuit breaker or load disconnect switches for the output busbar.
Protected with a second-level lightning protection system, the rated voltage limit of the system is AC690V, with the same protection level as string inverters at 65, meeting outdoor installation requirements, including UV resistance and salt mist corrosion protection.
This product significantly simplifies the wiring between string inverters and AC distribution panels or step-up transformers. The internal structure is simple and clear, with neatly arranged wiring. It boasts high reliability and easy maintenance. Outdoor wall-mounted installation is possible, capable of withstanding various harsh environments. In addition to standard materials and dimensions,
Available for customization upon customer request.

Electrical Technical Specifications

Key Features

● Enclosure meets IP65 protection rating, suitable for wall-mounted, sealed cabinets for outdoor installation requirements.
● Designed for simultaneous connection of multiple string inverters, each input line is protected with a thermal magnetic circuit breaker, with a rated voltage up to AC690V.
● Utilizes a dedicated high-voltage surge arrester to provide overvoltage and lightning protection between three phases; operating voltage exceeds AC480V.
● The busbars inside the box are all connected using electroplated or purified busbars, reducing the internal resistance of the busbars and the connection points.
Output is via circuit breakers, load isolating switches, or fuses.
