Installation of the solar kit
1. Before you install the solar kit, please make sure your 12V battery is not fully discharged. The
battery should produce at least 6V - this voltage is required to start the solar charge controller. If
your battery is fully discharged, please charge it by other means first for a short period of time.
2. Connect your 12V battery to the solar charge controller using the 3m cable with crocodile clips:
−
On the solar controller end, fix bare ends of the cable using screw terminals
−
On the battery end, use crocodile clips attached to the cable
Battery “+” should be connected to “+” battery terminal of the controller, battery “-“ should be
connected to “-“ battery terminal of the controller.
Please note: crocodile clips are provided for temporary use only. For permanent connection we
recommend using special battery terminals or your existing battery connectors.
3. Connect solar panel to the solar charge controller: “+” lead should be connected to “+” solar
terminal of the controller, “-“ lead should be connected to “-“ solar terminal of the controller. Your
solar kit should start charging the battery. For maximum output make sure the solar panel is
located outdoors and exposed to as much sunlight as possible without any shading. Even a small
shaded area can reduce the output significantly (e.g. leaves, trees etc.).
4. If needed, you can connect any 12V load or appliances to load terminals of the solar controller
(“+” to “+”, “-“ to “-“), for example 12V light bulbs. Make sure the total current drawn by the
load does not exceed 5A.
Your 12V load or appliances can also be connected directly to your battery, however in this case
the discharge protection function of the solar controller won’t work (the controller won’t be able to
cut off the load automatically when it’s over discharging the battery).
5. The solar panel and its connection box at the back are waterproof and can be used outdoors in
any weather conditions. Solar charge controller is not waterproof and should always be used
indoors.
6. Please refer to the solar controller manual for information on how to operate the controller.
