How to Protect Your Appliances from Dumsor and Power Surges in Ghana

Low voltage and surges when power returns destroy fridges, ACs and TVs. Here is which protection each appliance needs: fridge guards, stabilizers, surge protectors and UPS.

Many appliance repairs in Ghana start the same way: the lights flicker, power goes off, and when it comes back with a surge, something stops working. The right protection costs far less than a new compressor or TV board.

What damages appliances

  • Low voltage (brownouts): motors and compressors overheat trying to start.
  • Surges when power returns: a spike can burn control boards.
  • Rapid on-off cycles: compressors restarting before pressure settles.

Which protection for which appliance

ApplianceProtection
Fridge, chest freezerFridge guard or stabilizer with a delay timer
Air conditionerStabilizer sized for the AC
TV, decoder, sound systemSurge protector or stabilizer
Computer, Wi-Fi routerUPS (battery backup with surge protection)
Washing machine, microwaveSurge protector or stabilizer

See our voltage stabilizer guide for sizing.

How to size a stabilizer

  1. Add up the wattage of everything you will plug in.
  2. Choose a stabilizer rated comfortably above that total.
  3. For compressors (fridges, ACs), choose generously because they draw a burst of power when starting.

Why the delay timer matters

A good fridge guard or stabilizer waits a few minutes after power returns before switching your appliance back on. That lets the grid settle and protects compressors from restarting under pressure.

Habits that help

  • Switch off and unplug sensitive electronics during storms and long outages.
  • Don't overload extension boards; use proper surge-protected ones.
  • Have an electrician check your wiring and earthing.

Keep things running during outages

Read generator vs power station vs solar to compare backup options.
