Description

As an official distribution partner of Morningstar products across the globe, we are proud to offer solar charge controllers from this world-leading supplier. 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 Duo 25A 12V dual battery solar charge controller with LCD remote meter is well-recognised as the most powerful dual battery controller on the market and is suitable for various applications.

It is perfect 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% engine battery and 10% leisure 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 a built-in temperature sensor that allows charging adjustment depending on the ambient temperature.

The controller comes with a remote LCD display / meter which is connected via 10m cable (included). The remote meter can display various charging parameters such as solar panel current, battery voltages, amp-hours, temperature etc. The large numerical display and buttons allow easy navigation through the meter menu and a quick point of reference for your solar power system.
