Description
The ZJ Beny BYT-32 is a high-voltage DC isolator switch designed for safe disconnection of solar PV systems on the DC side. Rated at 1200V and 32A, this unit meets the rigorous AS 60947.3:2018 DC-PV2 standards, making it suitable for both residential and commercial solar installations across Australia. Housed in a durable, IP66-rated enclosure with a weatherproof isolator cover, it provides long-term resistance to dust, water, and extreme conditions.
Engineered for inverter-side isolation, the BYT-32 features patented arc-extinguishing technology that disconnects high-voltage DC safely and reliably within 3ms. It is designed with installer safety, code compliance, and wiring efficiency in mind. As a trusted solar DC isolator switch, the BYT-32 simplifies installation, ensures safety, and extends the lifespan of your PV system. For further technical reference, consult the ZJ Beny DC isolator datasheet or ZJ Beny isolator installation guide.

ZJ Beny
ZJ Beny (Zhejiang Benyi Electrical Co., Ltd.) is a global leader in solar DC protection solutions, known for manufacturing certified DC isolators, circuit breakers, and solar safety devices. As one of the most trusted ZJ Beny isolator suppliers in Australia, their products are widely deployed in rooftop PV, commercial systems, and utility-scale installations.
ZJ Beny’s DC isolators, including the BYSS, BYH, and BYT series, have been praised in numerous ZJ Beny DC isolator reviews for their quality, innovation, and installer-friendly design. Installers, EPCs, and system designers worldwide rely on the ZJ Beny DC isolator datasheet for critical specifications and installation best practices.
Start by identifying a suitable mounting location near the inverter’s DC input. Ensure all solar strings are safely disconnected. Mount the isolator using the pre-drilled holes. Connect the input/output terminals according to the ZJ Beny isolator installation guide and tighten with appropriate torque. Use side or rear conduit entries depending on space. Ensure the isolator cover is sealed properly before re-energizing.
The BYT-32 supports up to 1200V DC and features advanced arc-quenching tech. It complies with DC-PV2, features a lockable handle, and includes a breather valve for added enclosure safety. It is one of the few 1200V-rated isolators available with non-polarized switching and an IP66 isolator cover.
Yes. The 1200V/32A rating makes it suitable for a wide range of solar setups from residential rooftops to commercial buildings with multiple string configurations. It is also ideal for inverter-side disconnection.
Absolutely. The BYT-32 is compatible with most solar, hybrid, and battery inverter brands, as long as the voltage and current fall within spec. Always check your inverter’s input specs and installation requirements.
With IP66 protection, UV-resistant housing, and certified components, the BYT-32 is built for Australia’s harsh conditions. It is tested for over 20,000 mechanical cycles and thousands of electrical operations, providing dependable performance for years.
