Generator ATS or MTS what do they do?

So you are looking at a back-up generator, not sure how it is going to connect and what solution is best for you in your instance. Well lots of people have many question before buying so we have taken some time to explain both automatic transfer switches also known as ATS or AMF panels, manual transfer switches also know as MTS panels.

ATS - What does it do?

An ATS panel is know as switch-gear, this will connect between the generator and the main supply coming in or grid supply, know as your fuse box or consumer unit. It will constantly monitor the power supply and in the event of a power cut will will automatically send a signal to the generator to start up and also switch your power supply from mains/grid power to the generator supply. This process is taken care of with no need for human interaction and takes just seconds to complete from power off to power on. This ensure minimal disruption for the user and total peace of mind.

We advise an ATS as best solution for our customers as its easy to use and fast reacting, this will ensure that you stay powered up with no fuss and no stress either.

MTS - What does it do?

An MTS will do basically the same as ATS but as the name suggests, its a manual version. So what does that mean? In the event of a power cut you would need to start generator and also manually switch power supplies over on the switch gear. Also it would be up to you to monitor power supply to see when restored and switch back again. As the fact you need to start and stop it as needed this may to a better suit for some applications of use.

Basis example of connection.


When installing these options you need need to get them installed by a trained electrician, you will nee to factor this cost in when purchasing the unit. We supply option for our back-up generator ranges and prices will vary. As you would have though, an ATS will cost more than an MTS option. MTS will go from about £200 upwards and ATS option from £600 although nd on the makes/models you are looking at.
