KATKO Isolators allow you to build safe, flexible and functional solar power system. Learn more about their PV range here...

Katko PV Photovoltaic DC Isolator Switches

KATKO’s range of PV switches are used to break direct current so that solar panels or an inverter can be safely isolated for maintenance. PV switch can be installed for individual panels or a string of panels. Made of self-extinguishing material the Katko Photovoltaic (PV) isolators have been developed to be durable under difficult climatic conditions and require no extra protective coating.

Our Katko product range has been built in order to ensure safety, reliability and performance. With superior temperature performance including good resistance against UV and many chemicals. The Katko photovoltaic range is excellent for Solar Panel systems.

Safe Isolation in Solar Power System

You will find suitable products from KATKO product range to isolate both DC and AC side safely in your solar power application. Secure isolation of current is very important to handle the maintenance and fixing of the system. Dividing the panels to strings allows you to work safely and fluently only on critical parts of the system and allow the rest of the power generation to be utilized.

There is variance in national guidelines, how solar power applications should be built. However, all instructions and local requirements aim to have a safe and secure system. Local requirements should always be followed. KATKO general recommendation can be seen in the image below
