Sterling Power PRO COMBI S Pure Sine wave Inverter/Charger 12V 3500 Watt

The new Pro Combi range is designed to be very competitive, no frills, high performance, and value for money products, presented in a simple, easy to install and use style.
If you require power assist, parallel connection, three phase output functions or any other enhanced combi features then this range 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 out do the next with abilities beyond the understanding and requirements of most people. This detracts from the combi’s main strength of being easy to install and easy to use. There is, no doubt, a market for the advanced 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 cross over 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 though 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 A, whereas, Pro Combi can use as little as 2A.
Also, a lot of the expensive combis do not even have a power save function which can drop the combi power consumption to as little as 0.2A when off load, some combis continue to consume 2A + even when there is no load.
Sterling has reversed this trend with this Pro Combi range by stripping away the unnecessary features from a complex combi saving money. The end result is a simple, straight forward 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.
