The Pro Combi S+ is Sterling’s new inverter charger. It is a bespoke unit that has an attractive new design. The unit is lighter, smaller, yet more powerful than its
predecessor. New splash proof design offering some protection against the odd water spill. The Combi S+ also comes with an auxiliary charging output to allow
the user to charge their starter battery whilst bulk charging their main battery bank. The auxiliary charging is simply a module that can be installed and allows
the user to charge 12V from a 12V or 24V from a 24V or even a combination of them as it is simply a module (e.g. 12V from a 24V unit), unit built to IP22.
8 Battery type selectors. All with their own
4 stage charging profiles.
Features a power saver function and battery
charger power reduction. Great for smaller
power supplies and gensets.
30A automatic crossover switch: If shore power
is connected to the combi the unit allows
you to run your appliances directly from the
shore power. However, when shore power is
disconnected, the unit transfers the load from
shore power to inverter power in less than
20ms, ensuring a smooth uninterruptible power
The Battery chargers across the range are larger
in current rating. 70A at 12V - 35A for 24V.
Remote control panel included. The remote is
removable and can be replaced with a blank panel. The
switch panel can then be remotely mounted using the
supplied extension lead (10 meters).
12V and 24V models.

The additional 5A auxiliary charging output port
is a new feature of the S+ model. It allows the
user to charge the starter battery (example).
Also, you can pick and mix. For example, have
a 12V main unit with a 24V output port, or vice
Power Factor Corrected (PFC) This unit
