Can A Generator Run My Fridge?

We have a few different generator options at Total Tools. They range in price from R6953.94 to R16048.93:

Petrol Generator 4.5 Kva 3500w Recoil

Petrol Generator 4.5 Kva 3500w Elec Starter

Petrol Generator 6 Kva 5500w

Petrol Generator 8 Kva 6500w

Petrol Generator 10 Kva 7500w

The important thing to know about starting a fridge on a generator is that a fridge needs at least 1.5 times the running power to turn on its compressor. So, the generator you choose needs to be able to provide at least that amount of power. 

A secondary important thing is to know that if your fridge comes with a smart control panel or various sensors, then you should use an inverter generator instead. This is to avoid damaging the microprocessors that your fridge would be using with the THD (total harmonic distortion) of a regular generator.

To summarise:

Old fridge? Use a generator.

New fridge? Use an inverter.
