Change Over Switch
Systems for Generators and Solar Systems
EBS Services Email:sales@solarandbattery.co.za
A Change Over Switch is required when an external source of power (eg. Generator or Solar System) intends to supply a home or office when the main supply is interrupted (Eskom).
How it Works:
The Change Over Switch is “wired” into the Distribution Board of the building, specific circuits are Isolated (for example the computer room/server is supplied external power).These Switches also allows for a safe means to change from Eskom supply ,to a supply from a Generator or Solar System and can be manual or automatic (ATS-Automatic Transfer Switch).

Versatile:
They also act as a maintenance switch on Solar Systems, if the Inverter requires repair or the batteries are faulty the switch is used to bypass the System while repairs are carried out.
Type:
The main types of Change Over Switches are the Rail Mounted (installed inside a DB) or a Rotary (Tumbler) switch (External).
Applications:
- Generators
- Solar Systems
- Battery Backup Systems
- Other external supply
