There are 2 main models the Pro Combi Q for quasi-sinewave) and the Pro Combi S (for Pure-sinewave). So the simple question is what best suits your needs?

Pro Combi Q, (quasi-sine model) suitable for most installations, where you would use a microwave, fridge, hair dryer, vacuum cleaner, kettle, computer, etc The vast majority of products will run on quasi-sinewave.

Pro Combi S ( sine wave model ) where all the above plus washing machines, bread makers , thyristor controlled equipment are used - then sinewave is required
To make the choice even simpler, we have a 6 months exchange/upgrade policy.

If you purchase a Pro Combi Q and find there is some equipment that you cannot run due to the Quasi Sinewave and require Pure Sinewave, Sterling are happy to up-grade your quasi-sine unit for sinewave with the only cost being the difference between the 2 products (unit must be sent direct to Sterling and in good condition).
