The New Surge Guard App is Here!

Surge Guard released a new App that is compatible with the portable 34931 and 34951 Total Electrical Protection Systems.  The new App uses Bluetooth and allows you to do several things right from your phone which eliminates the need to read the LCD panel on the device in the event of a fault or error.

Surge Guard App Features

  • Monitors the power to your RV and reports usage
  • Shows errors in real time
  • Helps you understand error history
  • Provides easy access to troubleshooting and how-to guides
  • Shows when the power will be restored

Connecting to the App is simple and you can find the Surge Guard App in your phone's Apple or Android app store. The App is simply named "Surge Guard" and when you download it, it walks you through connecting and naming your device. It is simple to use and provides a lot of great information about your device and the power coming to your RV.

All Surge Guard 34931 and 34951 purchased from TechnoRV after the App launched will be compatible with the App.

If you have a Surge Guard 34931 or 34951 that was purchased before the App launched, you will need to check your device's date code to see if it is compatible out of the box.  If your unit has a date code older than 2232 (32nd week of 2022), you will need to follow the directions below to have your unit updated to be compatible with the new Surge Guard App.

You can find your date code on the back of your unit.
