This 10A 12V dual battery solar charge controller is designed to charge and protect 2 batteries or battery banks independently, having 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 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 1 battery? Yes, absolutely! The controller will determine automatically if there's only 1 battery connected and will pass 100% of power to this battery. You can add a second battery later.

This controller is perfect for the 40W solar panel included with the kit. In fact, it can work with solar panels up to 160W, so you will have some reserve capacity and will be able to add more 40W solar panel (up to 3 more) to your system without the need to change the controller. The unit has many protection functions, such as stopping reverse current at night (from the battery back to the solar panel), over charge protection, short circuit, reverse polarity protection etc. Other features include LED indicators, battery type selection (sealed, gel, flooded) and RJ-45 socket for a remote LCD meter (can be purchased separately - click to view our Remote meter / display for dual battery solar controller). A built-in temperature sensor allows adjustment of charging parameters depending on ambient temperature for more efficient charging.

Controller specifications:

• Fully automated operation
• 3 pairs of terminals (input, battery 1, battery 2)
• LEDs to indicate state of charge
• Temperature sensor for temperature compensation of charging (-30mV/C/12V)
• RJ-45 connection point for a remote meter (not included)
• Various protection features (over charge, short circuit, reverse polarity etc)
• Self-consumption: 4mA at night, 10mA when charging
• Working temperature: -35C to +55C
• Terminals for wire up to 4.0mm2
• Size: 15.5 x 7.6 x 4.0 cm
• Weight: 185 g
• Multiple mounting holes for ease of installation

The controller comes with a detailed instruction manual which explains settings and operation.

Other components of the solar kit

This kit includes a set of 4 plastic corner mounting brackets for fixing solar panel to the roof. The brackets can be bonded to the roof using an appropriate sealant (not included).

A waterproof double entry cable gland included with the kit is perfect for getting cables from outside to inside and keeping the place fully waterproof.

The kit also includes 5m double core battery cable. The full length of cable can be used for 1 battery, or it can also be cut into 2 pieces (e.g. into 2m and 3m) for use in dual battery systems. If more cable is required, you can purchase additional 5m double core battery cable.

Connection scheme

It's very easy to wire this kit up: just connect the first battery to Battery 1 terminals of the solar charge controller (battery "+" to "+" Battery 1 terminal of the solar controller, battery "-" to "-" Battery 1 terminal of the solar controller), then connect the second battery to Battery 2 terminals of the solar controller (skip this step if you only have one battery), and finally connect solar panel to the solar terminals of the controller (solar panel "+" to "+" solar terminal, solar panel "-" to "-" solar terminal) - and the kit is ready and will start charging immediately! Disconnection should follow the reverse order.
