This high-efficiency 300W 12V dual battery charging kit with lightweight folding solar panel is perfect for outdoor use to provide free electricity for charging 12V batteries to power various applications, such as in a motorhome, caravan, camper, boat, or for solar lighting systems, off-grid and back up solar power systems.
Solar kit includes:
- 300W lightweight folding solar panel
- Morningstar SunSaver Duo 25A dual battery solar charge controller
- Mornignstar RM-1 remote meter
300W lightweight folding solar panel:
This high-quality, waterproof, lightweight 300W folding solar panel is designed to provide free power for charging 12V/24V batteries, for example in vehicles and boats (motorhome, caravan, camper, narrow boat, yacht etc) or any other system with a 12V/24V battery bank. It is also excellent for portable power stations or portable battery banks if they allow a direct connection of a solar panel.
It is comprised of 3 x highly durable solar panels made from monocrystalline solar cells and reinforced with anodised aluminium and a strong ETFE surface. This is the ideal solution for experiencing the benefits of solar without the permanency of a mounted solar panel, as this panel can be folded and stored away when not in use.
This high-efficiency 300W (3 x 100W) folding solar panel comes with:
- Adjustable aluminium folding stand
- 5m battery extension cable
- 4 cables with different terminal ends, including crocodile clips and bare ended, to connect the panel to your choice of solar charge controller or portable power station
- Protective storage case
Key features:
- Lightweight (only 10.54 kg) and easily transportable using the inbuilt handles and protective case.
- Suitable for all weather conditions - 100% waterproof.
- High efficiency 3 x 100W folding solar panels are made of innovative zero-busbar solar cells which have significantly higher efficiency and power density compared to standard solar cells.
- Adjustable aluminium folding stand for positioning the solar panels towards direct sunlight to maximise their output.
- Sturdy storage case made with a layer of protective foam to prevent accidental damage to the solar panel.
Lightweight aluminium-reinforced solar panels:
The high-efficiency solar cells perform exceptionally well in low light conditions and they produce a good amount of power simply in daylight, even when direct sunlight is not available.
These reinforced solar panels feature an embedded sheet of anodised aluminium fully encapsulated within the solar panels for added strength and resilience. In addition, the surface of solar panels is made of strong ETFE material which has a longer service life compared to standard lightweight solar panels. As a result, these solar panels are extremely hard-wearing and less prone to cracking, delamination and corrosion. The lightly textured coating of this panel creates an anti-reflective surface which allows the panel to absorb a far greater amount of light, thereby increasing efficiency.
Morningstar SunSaver Duo 25A dual battery solar charge controller:
This high quality Morningstar SunSaver Duo 25A 12V dual battery solar charge controller 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% 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 and battery type selection (sealed, or flooded - two batteries can have different types).
Additional items:
The kit also includes a Morningstar RM-1 remote meter.
