Smaller and more powerful smart combi inverter-charger launched

The inverter/charger is now de rigeur for most small to medium-sized cruising boats.

They save space, reduce installation time and cost and provide all the AC needs when the vessel is away from a shore-side AC supply. 

One player in the supply of combi inverter/chargers is UK marine electrical company, Sterling Power, which will exhibit its new Pro Combi S+ at this year’s METSTRADE show.

This new, splashproof design is lighter and smaller than its predecessor, with all of the AC and DC connectors now integrated neatly into the unit, eliminating the need for terminal safety caps. 

The Pro Combi S+ features eight battery type selectors, each with a four-stage charge profile.

Whilst it offers more power and improved overload ability, it also requires less current when in standby mode.  

“This new combi is better than ever," said MD Charles Sterling. "Not only is it capable of supplying a continuous load of 1300W, but it can also cope with supplying up to 1600W for ten minutes, while the quiescent current draw has been reduced to just 0.1A in power save mode and 0.5A with power save off.” 

The unit comes with a 12-24V/5A auxiliary charging module that enables the user to charge their engine start battery whilst bulk charging their main battery bank.

A removable control panel and extension lead is also included, which can be located remotely up to 10m from the main unit if required. 

One problem frequently encountered with all combis is that they will remain in inverter mode should the shore power be disconnected for any reason, which can flatten the service batteries if any devices are left on.

To avoid this scenario the Combi S+ has a battery charge only option.
