Inverters with a Built In Transfer Switch
An Inverter with a built in Transfer Switch is a good item to have attached to an electrical back up
system. The best use for a transfer switch with an inverter is when the grid power goes down. It
will switch from grid to backup power so fast you will not even notice the change over. Without the
inverter you would have to wait for the generator to spin up before the lights came back on.
If you are using an external transfer switch you will need to place a breaker in both feed lines and after the transfer switch. If you are running from grid power and something fries in your TV or toaster and trips the breaker on the grid side, the transfer switch will auto switch you to your battery backup which is not a good thing. If you are lucky the backup power breaker will trip as well. But it might not in time to prevent a fire from wires over heating. So put a breaker after the transfer switch.
Inverters that have a transfer switch built in could save a little in wiring and an extra breaker. This
is because normally there will be a breaker in the AC line going to the these types of inverters and then a main breaker and a line breaker in the line going from the inverter to the House, RV or what ever the load may be. Built in chargers allows you to wire from your house breaker box to the inverter which can keep your battery bank charged as well as power the system. The built in transfer switch will bypass the inverter till the outside power goes down.
You can find a transfer switch in standard sizes 30 amps, 50 amps and 100 amps at a fair price in our webstore.
