Photonic Universe 120W 12V semi-flexible dual battery solar charging kit

Product Description

This high-efficiency semi-flexible 120W dual battery solar charging kit is perfect for permanent 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:


120W black semi-flexible fibreglass solar panel with a durable ETFE coating
10A 12V dual battery solar charge controller for independent charging of 2 batteries or battery banks (can work with a single battery too)
A pair of 5m 4.0mm² single core extension cables with MC4 connectors
5m of4.0mm²dual core battery cable




120W Black semi-flexible fibreglass solar panel:

This highly durable black semi-flexible solar panel reinforced with fibreglass plastic has a surafce made of strong ETFE material which has a longer service life compared to standard semi-flexible solar panels. As a result, these particular semi-flexible 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. ETFE material has long been used in applications where durability and high-temperature resistance is required, such as in the Eden Project, Cornwall. You can read more about ETFE and its benefits here.

This panel also features new generation 5-busbar solar cells, which are more efficient than the 2, 3 or 4 busbar solar cells used in most other solar panels, and are able to extract more power from the same surface area. This results in a smaller overall solar panel, which is ideal for applications where space is limited.

This solar panel has a unique black backing,making it ideal for discreet andaesthetically pleasing installation on dark coloured roofs, vehiclesor mounting surfaces. Please note that this solar panel is not 'ultra jet-black' - the exacthue may vary marginally from panel to panel, depending on the batch of solar cells.

The semi-flexible design of this panel makes it ideal for curved roofs and surfaces where bonding is preferable (though the panel can also be fixed by bolts or screws). The panel is alsoincredibly light (only 2.19kg) which makes it an ideal option for all vehicle applications. This panel is also highly resistant to salt water environments andit is also possibleto walk on the panel, making it theperfect choicefor boats and yachts.

The panel is fitted with 2 x 1m of cable(4mm² cross section) with MC4 connectorson the end which simply plug into the 5m extension solar cable supplied with the kit, to join the solar panel and the charge controller.

10A Dual battery controller:

The kit includes a 10A 12V/24V dual battery solar charge controller designed to charge and protecttwo batteries independently, with automatic cut off to prevent over-charging. The controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance and prolongs the life of your batteries. PWM technology can also recover some lost battery capacity

This is a perfect solar controller for a caravan / camper van / boat or another system withtwo batteries (e.g. engine and leisure battery) or battery banks. You can set the initial charging priority e.g. 80% power to go to the engine battery and 20% to leisure battery. When one of the batteries is fully charged the controller will automatically divert all power to the other battery.

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

The unit hasnumerous safety functions, including protection againstreverse current at night (from the battery back to the solar panel), over charge, short circuit, reverse polarity etc. Other features include various LED indicators, battery type selection (sealed, gel, flooded) and an RJ-45 socket for an optional remote LCD meter with 10m cable.

A built-in temperature sensor allows the controller to optimise the charging process depending on the ambient temperature. If you are planning to position the controller far away from the battery, or if the battery and the controller are exposed to different ambient temperatures, an external remote temperature sensor with 3m cable is recommended for this dual battery solar charge controller. To enable connection to the screw terminals of the controller, the green connector block on the end of the remote temperature sensor cable should be cut off.

The solar chargecontroller is compatible with sealed, gel and flooded lead acid batteries.

Additional items:

The kit also includes a pair of 5m positive and negative solar extension leads (4.0mm²cross section) and 5m of 4.0mm²dual core battery cable for use between the solar charge controller and your battery, making the total cable length between the solar panel and the battery 1m + 5m + 5m = 11m.
