20W solar panel:

This kit includes a waterproof, high efficiency 20W solar panel that is perfect for permanent outdoor use to provide free power for charging a 12V battery. This power can then be used to operate various devices for many applications (e.g. 12V lights, fan, water pump, electric fence etc). Additionally, the kit can be used to charge a leisure battery in a camper, caravan, or boat. The long-lasting, high-efficiency, polycrystalline cells and the tough, sealed aluminum frame will provide years of consistent, free power. The waterproof design ensures that the panel can be used in all weather conditions. The panel comes with a 3m cable attached to the waterproof junction box at the back. Please note that the junction box protrudes approximately 0.5cm beyond the frame, meaning that there must be some space left between the frame and flat surface when mounting the panel (note 1.0 - 1.5cm space under the panel is typically recommended for cooling).

5A solar charge controller:

This kit includes an advanced 5A solar charge controller designed to protect your 12V battery while charging. The controller has a 5V USB port (1.2A output) for fast charging of USB compatible devices (e.g. mobile phones, tablets, mp3 players etc) as well as a pair of load terminals for connecting 12V loads (such as lights) if desired. It can work with sealed, gel, and flooded batteries, and the battery type can be easily set. The unit also has a pair of terminals for connecting your 12V loads if necessary (such as lights etc). This solar controller stops reverse current at night (from the battery back through the solar panel) so your battery won't lose any charge. It has many other protection functions such as overcharge/discharge, overload, short circuit, overheating, etc. Additional features include LED indicators, a battery type switch, and a load "on/off" button.

Additional items:

The solar kit comes with a 2m battery cable including a fuse and crocodile clips for easy connection to your battery. You will also receive a user manual with instructions for a quick and safe installation. Moreover, advanced users will find an additional user manual for the solar controller in the documents tab.
