100W (50W 50W) dual battery solar charging kit with 10A charge controller and cables, for motorhome, caravan, boat or any 12/24V battery system

This kit includes: 2 x 50W high efficiency waterproof monocrystalline solar panels, each with 5m cable and MC4 connectors 10A Photonic Universe solar charge controller.   2 x 50W solar panels: This 100W system is perfect for permanent outdoor use to provide free electricity for charging 12V batteries to power various applications such as in a camper van, motorhome, boat, shed, farm, as well as remote applications such as telecommunications or monitoring equipment. It can also be used to provide a direct power supply for applications not sensitive to changes in input voltage / current (e.g. electric motors or pumps). Each panel is fitted with 5m of special solar cable which can work at high roof temperatures, with minimum power losses. A pair of male / female MC4 connectors are crimped on the end of cable for easy connection to other solar panels, extension leads or to your existing system (the MC4 connectors can also be cut off when wiring to the screw terminals of a solar charge controller). The long-lasting, high-efficiency monocrystalline solar cells and the tough, sealed, aluminium frame will provide years and years of consistent, free power. The waterproof design ensures that the panels can be used in all weather conditions. 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. This results in a smaller overall solar panel, which is ideal for applications where space is limited. These solar cells are also the best choice for applications in warmer climates, as they operate well even in high ambient temperatures. 10A solar charge 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 many protection functions, such as stopping 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. This controller can work with solar panels up to 160W, which means that it has enough reserve capacity to add another 50W solar panel to your system at a later date, without the need to change the controller. Please note: This is an essentials kit and does not include mounting accessories or battery cable. If you require these additional items, please purchase them separately.
