320W 12V dual battery solar kit for camper / boat with controller and cable

320W 12V dual battery solar kit for camper / boat with controller and cable

320W solar panel:

This high efficiency, waterproof 320W 12V monocrystalline solar panel 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).

The 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 to other solar panels, your existing system or 6mm extension cable?ÿ(the MC4 connectors can also be cut off when wiring to the screw terminals of?ÿthe solar charge controller).

The long-lasting, high-efficiency monocrystalline solar cells and the tough, sealed, aluminium frame will give you years and years of consistent, free power. The waterproof design ensures the panel can be used in all weather conditions.

This panel also features innovative 5 busbar solar cells, which are more efficient than the?ÿ2, 3 or 4?ÿbusbar 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?ÿhigh ambient temperatures.

20A solar charge controller:

The kit includes a 20A 12V/24V dual battery solar charge controller designed to charge and protect?ÿtwo 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?ÿtwo 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?ÿone battery? Yes, absolutely! The controller will determine automatically if there's only?ÿone 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.

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.
