IGOYE 32A DC 1200V Solar Disconnect Switch Isolator – IP66 Waterproof, MC4-Compatible

This heavy-duty DC isolator from IGOYE provides a reliable way to isolate photovoltaic strings, inverters, charge controllers, and other solar components. Built with an IP66-rated enclosure and standard MC4 terminal compatibility, the unit balances outdoor durability with convenience for installation and maintenance. It’s engineered for intermittent switching and emergency isolation in rooftop, ground-mount, and off-grid systems.

How does this disconnect switch protect my solar system?

The IGOYE disconnect creates a clear open-circuit point in the DC side of your PV installation so technicians can work safely and systems can be quickly isolated during troubleshooting. Its sealed housing prevents water and dust ingress, and the mechanical design supports many cycles of operation without compromising contact integrity.

• IP66-rated waterproof and dustproof enclosure for outdoor use
• Rated insulation voltage up to 1200V suitable for high-voltage arrays
• Mechanical life rated for thousands of operations for dependable switching

Will it work with my existing MC4-connected panels and inverters?

The unit uses the common MC4-compatible terminal format for straightforward connections to standard PV cables and connectors. Quick connect/disconnect features and automatic locking simplify wiring, reducing installation time and the chance of errors during assembly.

• Standard MC4 terminal connections for plug-and-play compatibility
• Automatic locking for secure cable attachment under load
• Can disconnect 1–4 MPPT strings depending on system layout

What electrical ratings and limits should I consider?

Choose the IGOYE isolator when your system’s DC voltage does not exceed 1200V and the current is within the 32A rating. The device is available with selectable working voltage thresholds (300V, 600V, 800V, 1000V, 1200V) and a rated insulation voltage of 1200V to match different PV architectures.

• Rated current: 32 A maximum
• Working voltage options: 300V / 600V / 800V / 1000V / 1200V
• Rated insulation voltage: 1200V for high-voltage protection

How does the enclosure and build quality handle outdoor conditions?

The switch is housed in a robust enclosure with a waterproof sealing ring engineered to withstand rain, dust, and routine environmental exposure. IP66 certification means it is protected against powerful water jets and is dust-tight, making it suitable for rooftop and field-mounted solar installations.

• IP66 waterproof rating for reliable outdoor performance
• Sealed gasket design reduces risk of moisture ingress and corrosion
• Durable housing materials tolerate UV and weathering in solar settings

Who is this for: The IGOYE 32A DC1200V Solar Disconnect Switch is aimed at solar installers, electricians, and system owners who need a robust, MC4-compatible DC isolator for medium to large photovoltaic systems. It suits rooftop arrays, ground-mounted farms, off-grid setups, and commercial projects where a weatherproof, easy-to-install disconnect is required for safe maintenance and emergency isolation.
