Innovative design from years of dedicated research and superior build quality enable these top-of-the-range solar charge controllers to extend battery capacity and life, maximise energy production, and consistently achieve high performance standards.

This high quality Morningstar SunSaver Duo25A 12V dual battery solar charge controller is well-recognised asthe most powerful dual battery controller on the market and is suitablefor various applications.

It isperfect for caravans, motorhomes, boats or other systems with 2 batteries (e.g. engine and leisure battery). You can set initial charging priority e.g. 90% leisure battery and 10% engine battery. When one of the batteries is fully charged the controller will automatically divert all power to the other battery.

Other key features of this controller include:


Extremely high reliability, with a long 5 year warranty and estimated 15 year life
Negative common ground - ideal for most motorhomes, boats and stationary applications
Epoxy encapsulation protects the controller against dust and high humidity
Four stage series PWM pulse charging increases your battery life
Specific settings, such as slow switching charging mode for sensitive loads to avoid interference
Lower system cost as the two battery charging eliminates the need for two separate solar power systems
Easy to install and use, with factory pre-sets, fully automatic operation and fault recovery




Can the unit work with only 1 battery? Yes, absolutely! The controller will determine automatically if there's only 1 battery connected and will pass 100% of charging current to this battery. You can add a second battery later.

This powerful 25A controller can work with solar panels up to 400W. It has many protection functions, such as stopping reverse current at night (from the battery to the solar panel), over charge, short circuit, reverse polarity etc. Other features include an LED status indicator, battery type selection (sealed, or flooded - two batteries can have different types) and RJ-11 socket for a remote LCD meter (see Morningstar SunSaver Duo25A dual controller with LCD remote meter). A built-in temperature sensor allows charging adjustment depending on the ambient temperature.
