ATS 6–15 kW Automatic Transfer Switch for Generators

The ATS 6–15 kW is an automatic transfer switch (ATS) for 6–15 kW generators: it is the model for lower-rated generators, while a 20 kW generator calls for the ATS 20 kW. When mains power fails, it transfers the load to a generator, solar inverter or UPS within a few milliseconds.

Technical specifications

How the ATS 6–15 kW differs from the ATS 20 kW

Transfer time, interlocks and automatic restore are described identically for both models: only the generator rating and the product code differ. Choose the ATS 6–15 kW when your generator is rated 6–15 kW. If you have a 20 kW generator, the ATS 20 kW is the one to look at. If your rating is different or you are not sure, send us the generator model and Hybrid Energy will check which ATS fits.

What is an ATS switch for a generator used for in a house, office or server room?

• Detached houses with a 6–15 kW generator
• Photovoltaic systems: switching to energy storage after dark or when the grid supply fails
• Offices and server rooms, to protect critical IT infrastructure

How does an automatic changeover between the grid and a generator work?

The ATS detects a failure of the main grid and transfers the load to an alternative source within a few milliseconds. When grid power returns, the mains supply is restored automatically.

Built-in mechanical and electrical interlocks prevent two energy sources from being switched on at the same time.

Which generators and sources is the ATS 6–15 kW compatible with?

This ATS is compatible with generators rated 6–15 kW. The alternative source can be a generator, a solar inverter or a UPS. If you have a specific generator or inverter model, send it to us and Hybrid Energy will check whether it fits.
