Product Description

● CNLonQcom is a manufacturer specializing in the production of PV Switch-disconnectors up to 1500V 32A, designed for residential or commercial photovoltaic systems ranging from 1kW to 20kW. These switches are intended for installation between solar panels and charge controllers, solar panels and inverters, or between solar panels themselves.

● Featuring pre-wired PV Switch-disconnectors with solar connectors, our products allow for faster and safer installations. With the capability to disconnect loads up to 8 times the rated current, they are an ideal choice for any occasion requiring electrical isolation such as repair, maintenance, inspection, and installation.

● Moreover, our PV Switch-Disconnectors up to 1500V 32A come with an IP66 waterproof case, providing exceptional protection levels, made from high-quality plastic materials, UV resistant, and offering options for 2-4 poles suitable for distribution boxes. Compact in design and suitable for outdoor use, they protect your isolator switches from rain, dust, and other weather elements.

● The compatibility of our PV Switch-disconnectors with solar connectors makes it suitable for solar power systems in RVs, ships, and off-grid/on-grid solar systems, specifically designed for home solar systems and commercial solar systems. It offers comprehensive protection with an independent and enclosed isolator switch and a padlock that ensures it remains locked in the OFF position and tamper-proof.
