1200V DC Photovoltaic Isolator with Standard MC4 Connectors
The 1200V / 32A DC photovoltaic isolator is the component that allows safe isolation of the solar circuit without disassembling cables or panels. Designed for high-voltage solar systems, it supports configurations with 2 input strings and 2 outputs via MC4 connectors compatible with industry-standard cables. The IP66 enclosure makes it suitable for permanent outdoor installation, including on roof structures or terrain exposed to harsh weather.
What you get with this product
- Safely isolate the entire solar system from a single control point, without special tools
- Connect two panel strings simultaneously — the 2 IN / 2 OUT configuration eliminates the need for a separate splitter
- MC4 connectors included — directly compatible with standard solar cables, no adapters or soldering required
- IP66 enclosure resistant to rain, dust, and UV — operates without degradation in harsh climatic conditions
- 1200V DC nominal voltage and 32A current — covers residential and semi-commercial installations without scale limitations
- Clear ON/OFF mechanical operation with visual locking — you always know if the circuit is energized
How it works and how to install it
The isolator is installed in the DC line between the photovoltaic panels and the inverter, before any other protection or meter. Connection is made directly via MC4 plugs: the two input connectors receive cables from the panel strings, and the two output connectors go to the inverter or the DC distribution board. No special electrical tools are required for intervention — mechanical installation is done using fixing screws on the wall or supporting structure, and electrical connections are manually clipped using the MC4 standard.
Frequently Asked Questions
Can I use this isolator with a 1000V inverter?
Yes. The nominal voltage of 1200V DC is the maximum allowed value, so it works correctly and safely with 600V, 800V, or 1000V systems.
Is it compatible with any MC4 solar cable on the market?
The included MC4 connectors comply with the universal industrial standard, making them compatible with 4mm2 and 6mm2 solar cables commonly used in photovoltaic installations.
Can it be mounted directly outdoors, on the roof or on the panel structure?
Yes, the IP66 protection rating ensures complete sealing against water jets and dust, allowing permanent outdoor mounting without an additional protective enclosure.
