Solar kit includes:
- 2 x 50W reinforced narrow semi-flexible solar panels with a durable ETFE coating (German solar cells)
- 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 4.0mm thick single core extension cables with MC4 connectors
- 2 x 5m 4.0mm dual core battery cables with a fuse holder, 10A fuse and 8mm ring terminals
- A pair of T-branch MC4 connectors, for connecting the panels in parallel
2 x 50W Reinforced narrow semi-flexible solar panels:
These reinforced semi-flexible solar panels have a unique 7-layer construction, featuring an embedded sheet of anodised aluminium fully encapsulated within each solar panel. This additional reinforcement offers greater strength and resilience, making them amongst the most robust semi-flexible solar panels available on the market.
In addition to the aluminium reinforcement, the surface of these 50W semi-flexible solar panels is 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 these panels creates an anti-reflective surface which allows the panels 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.
The high-efficiency monocrystalline German solar cells used in these solar panels have excellent performance in low light conditions (particularly when compared to solar cells of unknown origin) and they produce a good amount of power even in daylight – when direct sunlight is not available. These panels also feature innovative 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.
The semi-flexible design of these panels makes them ideal for curved roofs and surfaces where bonding is preferable (though the panels can also be fixed by bolts or screws). The panels are also incredibly light (only 2kg each) which makes them an ideal option for all vehicle applications. The unique narrow design also make them ideal for applications where space is restricted, or where there are obstructions on the roof. The panels are also highly resistant to salt water environments and it is also possible to walk on the panels, making them the perfect choice for boats and yachts.
The panels are fitted with 2 x 90cm of cable with MC4 connectors on the end.
10A Dual battery controller:
The kit includes a 10A 12V/24V dual battery solar charge controller designed to charge and protect two 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 with two 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 only one battery? Yes, absolutely! The controller will determine automatically if there’s only one battery connected and will pass 100% of charging current to this battery. You can add a second battery later.
The unit has numerous safety functions, including protection against reverse 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 charge controller is compatible with sealed, gel and flooded lead acid batteries.
The kit includes 5m positive and negative 4.0mm solar extension leadsfor connecting the solar panels to the solar charge controller, and a 5m 4.0mm dual core battery cable fitted with a 15A fuse, fuse holder and 8mm ring terminals for use between the solar charge controller and your battery, making the total cable length between the solar panels and the battery 1m + 5m + 5m = 11m.
A pair of T-branch MC4 connectors is also provided, in order to connect these panels in parallel.
