If you require power assist, parallel connection, three phase output functions or any other enhanced combi features then this inverter is not for you . If you're not familiar with these things this ProCombi is perfect for you.

Modern combis are getting more and more complex, with each company trying to outdo the next with abilities beyond the understanding and requirements of most people. This detracts from the combis main strength of being easy to install and easy to use. There is, no doubt, there is a market for all the sexy functions but the vast majority of combi users simply do not need them and never will. Most people simply require the unit to act as a high performance constant current battery charger when on mains power then crossover to act as an efficient inverter when on battery – and that's it!

The problem with enhanced functions is, even if they are not used, they eat up valuable power. The more functions on a product running (even thought you do not use them) the higher the quiescent current on the inverter (the current the unit uses itself to operate). Complex combis at 12V can use as much as 9.5 amps whereas Pro Combi can use as little as 2 amps.

Sterling have reversed this trend with this Pro Combi range by stripping away the unnecessary features from a complex combi, not only saving money but also lowering the critical quiescent current draw. The end result is a simple, straightforward product that does what you think it should. Using our years of experience in this market we have tailored the product range to suit 90% of people purchasing Combis.

We have also added what we see as important features to this range that even the expensive combis do not have such as the ability to charge totally flat batteries and allow through power with no batteries connected.

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 Power is happy to up-grade your quasi-sine unit for a sinewave unit with the only cost being the difference between the 2 products and the cost of shipping (unit must be sent direct to Sterling and in good condition).
