About this item
IGOYE 32 Amp DC1200V Solar Disconnect Switch
The IGOYE 32 Amp DC1200V Solar Disconnect Switch is a safety device designed to quickly and reliably isolate the DC side of a solar photovoltaic (PV) system. It is essential for maintenance, troubleshooting, and emergency situations to safely disconnect the solar array from the rest of the system, protecting personnel and equipment.
With a high DC voltage rating of up to 1200 volts and a 32 amp current rating, this disconnect switch is suitable for medium-to-large solar installations used in homes, commercial buildings, and off-grid systems.

Design & Build Quality
The IGOYE solar disconnect switch is constructed with a rugged, weather-resistant housing designed for outdoor solar installations. Its durable build ensures long-term use in challenging environments, protecting internal components from dust, moisture, and UV exposure. The switch mechanism is robust and designed for reliable repeated operation.
The enclosure typically supports locking in the OFF position to prevent accidental reconnection, which is a key safety feature during maintenance and repair.
Functionality & How It Works
A solar disconnect switch provides a manual means to isolate the DC power produced by solar panels before reaching the charge controller, inverter, or other downstream equipment. Using a DC-rated switch is critical because AC-rated switches can arc and fail when interrupting DC currents.
Key functional benefits:
Quickly isolates solar array for safe maintenance
Prevents back-feeding of current during service
Improves overall system safety and compliance
Reduces risk of electrical shock and fire hazards
For safety and code compliance, many solar electrical standards require a disconnect means at the PV array.
Installation & Use Cases
Installation of the solar disconnect switch should be done by a qualified electrician or certified solar technician. Typical steps include:
Locate the switch near the solar array or combiner box
Mount the enclosure in a dry, accessible location
Connect DC conductors from the solar array to the switch input
Connect switch output to the charge controller or DC distribution
Test the switch operation before system commissioning
Use cases:
Residential rooftop or ground-mount solar systems
Commercial PV arrays
Off-grid solar systems with battery banks
Solar installations requiring service disconnect
Proper labeling and compliance with local electrical codes are essential for system safety and inspection.
Pros & Cons
| Pros | Cons |
|---|---|
| High voltage rating up to DC 1200 V | Manual operation only (non-automatic) |
| 32 Amp capacity for medium systems | Requires qualified installation |
| Durable, weather-resistant design | Adds cost to the overall solar system |
| Lockable OFF position for safety | Not a substitute for breaker protection |
| Essential for maintenance and safety compliance | Must be mounted in an accessible location |
