1200V DC Photovoltaic Isolator with MC4 Connectors
The 1200V / 32A DC solar photovoltaic isolator is a safety component that allows for the controlled disconnection of a string of solar panels directly from the source, without intervention in the electrical panel. Designed for residential and commercial solar installations, it offers a quick and safe way to interrupt the DC circuit in case of maintenance or emergency. The UV-resistant and weather-resistant housing ensures reliable long-term outdoor operation.
What you get with this product
- Fast and safe disconnection of the solar string — reduce electrical risk during system interventions, without special tools
- Native compatibility with standard MC4 connectors — integrates directly into existing panel wiring without additional adapters
- IP66 protection — resistant to water jets and dust, safely mounted on roofs or structures exposed to the elements
- Supports up to 1200V DC and 32A — suitable for medium and large solar power systems, including configurations with multiple panels in series
- UV-resistant plastic housing — does not degrade under prolonged sun exposure, retaining its mechanical and insulating properties
- IEC60947-3 and AS60947.3 certified, DC-PV2 class — meets international standards for DC photovoltaic isolators
How it works and how to install
The isolator is installed in series on the DC cable between the panels and the inverter, using the included MC4 connectors — 1 IN / 1 OUT configuration for a single string. Turning the handle from the ON to the OFF position completely interrupts the DC circuit, allowing for safe interventions. Installation does not require advanced electrical knowledge: connect the positive and negative cables from the panel string to the MC4 inputs, fix the housing to the desired surface, and the installation is ready.
Frequently Asked Questions
Can I use this isolator with any type of solar inverter?
Yes, the isolator is compatible with any solar inverter that uses cables with MC4 connectors, regardless of the inverter manufacturer.
Is it safe to mount it outdoors, exposed to rain and sun?
Yes, the housing has an IP66 protection rating, which means complete protection against dust and water jets, and is specifically designed for outdoor mounting.
Does it also work with off-grid solar systems, not just on-grid?
Yes, the isolator works with any DC photovoltaic system up to 1200V and 32A, including off-grid systems with batteries or hybrid systems.
