120w Dual Battery Charger 12v Solar Panel Kit for Camper Yacht Ready to go

120W solar panel kit:

This highly efficient, 120w Dual Battery Charger waterproof 120W 12V monocrystalline solar panel with a dual battery charger is ideal for permanent outdoor installation. It provides free electricity to charge 12V batteries, powering a range of applications from camper vans and motorhomes to boats, sheds, and farms. It’s also suitable for remote uses like telecommunications or monitoring equipment, and can directly power devices that aren’t sensitive to input voltage/current fluctuations.

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 other solar panels, extension leads or to your existing system (the MC4 connectors can also be cut off when wiring to the screw terminals of a 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.

Solar panel specifications:

• Peak power: 120W
• Maximum power voltage: 20.2V
• Maximum power current: 5.94A
• Open circuit voltage: 23.9V
• Short circuit current: 6.31A
• Power allowance range: +/- 3%
• Dimensions: 100.5 x 67 x 3.5 cm
• Weight: 8.3 kg
• 4 mounting holes 9 x 14 mm
• 2 x 5m of high quality single core solar cable 4.0mm cross section
• Male and female MC4 connectors attached (can be cut off when wiring to the solar controller)

This panel incorporates cutting-edge 5 busbar solar cells, which surpass the efficiency of the 2, 3, or 4 busbar solar cells commonly found in other solar panels. They can harness more power from the same surface area, leading to a more compact solar panel size—perfect for space-constrained applications. Additionally, these solar cells are optimal for use in warmer climates due to their excellent performance in high ambient temperatures.

10A solar charge controller:

The kit comes with a 10A 12V/24V dual battery solar charge controller, engineered to independently charge and safeguard two batteries, featuring an automatic cutoff to prevent overcharging. The controller employs PWM (Pulse Width Modulation) technology to enhance charge acceptance and extend battery lifespan. Additionally, PWM technology has the capability to restore some lost battery capacity.

PWM Charge controller specifications:

• Fully automated operation and auto 12/24V selection
• 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)
• Additional connection point for a remote temperature sensor (not included)
• RJ-45 connection point for a remote meter (not included)
• Various protection features (over charge, discharge, short circuit, over load, battery 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

This is a perfect solar controller for a caravan / camper van / boat or another system with two 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 one 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 enables the controller to optimize the charging process based on the ambient temperature. If the controller is to be placed far from the battery, or if the battery and controller are subject to different ambient temperatures, it is advisable to use an external remote temperature sensor with a 3m cable for this dual battery solar charge controller. For connecting to the controller’s screw terminals, the green connector block at the end of the remote temperature sensor cable must be removed.

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.
