This kit includes:

• 160W monocrystalline solar panel with 5m of solar cable and MC4 connectors
• 20A Photonic Universe dual battery PWM solar charge controller

160W solar panel:

The waterproof, high efficiency Photonic Universe 160W monocrystalline solar panel included in this kit is perfect for permanent outdoor use to provide free electricity to charge a 12V battery to power hundreds of devices and electrical appliances.

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

The panel comes with 5m of special solar cable which can operate at high roof temperatures, with minimum power losses. A pair of male / female MC4 connectors are crimped on the end of the cable for easy connection to the 20A solar charge controller (MC4 connectors can also be cut off when wiring to screw terminals of a solar charge controller).

Each individual solar panel is thoroughly tested to the highest quality standards, and labelled with a unique serial number for further quality control and increased warranty protection.

20A solar charge controller:

The 20A 12V/24V dual battery solar charge controller included in this kit is designed to charge and protect two batteries simultaneously, 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 2 batteries (e.g. engine and leisure battery) or two battery banks. You can set initial charging priority e.g. 80% engine battery and 20% leisure battery. When one of the batteries is fully charged the controller will automatically divert all current to the other battery.

Can the unit work with only 1 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.

The controller is not waterproof and should be used indoors.

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.
