This package includes 2 x 50W high efficiency, waterproof monocrystalline solar panels, each with 5m cable and MC4 connectors.

This 100W system is perfect for permanent outdoor use to provide free electricity for charging 12V batteries to power various applications such as in a camper van, motorhome, boat, shed, farm, as well as remote applications such as telecommunications or monitoring equipment. It can also be used to provide a direct power supply for applications not sensitive to changes in input voltage / current (e.g. electric motors or pumps).

Each 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 provide years and years of consistent, free power. The waterproof design ensures that the panels can be used in all weather conditions.

These panels also feature innovative 5 busbar solar cells, which are more efficient than the 2, 3 or 4 busbar solar cells used in most other solar panels, and are able to extract more power from the same surface area. This results in a smaller overall solar panel, which is ideal for applications where space is limited. These solar cells are also the best choice for applications in warmer climates, as they operate well even in high ambient temperatures.

Specifications (per panel):

  • Peak power: 50W
  • Maximum power voltage: 20.2V
  • Maximum power current: 2.48A
  • Open circuit voltage: 23.9V
  • Short circuit current: 2.63A
  • Power allowance range: +/- 3%
  • Dimensions: 590 x 505 x 25mm
  • Weight: 4.2 kg
  • 4 mounting holes 6 x 9 mm
  • 2 x 5m of high quality single core solar cable 2.5mm cross section
  • Male and female MC4 connectors attached (can be cut off when wiring to the solar controller)

The following 10A 12V/24V dual battery solar charge controller* is included in the kit:

Photonic Universe dual battery solar charge controller

This 10A 12V/24V dual battery solar charge controller is designed to charge and protect 2 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 2 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 1 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.

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 LCD 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

The controller is packaged in its original carton box and comes with a detailed user manual.

Installation:

  • For charging a 12V battery or 12V battery bank: The 2 x 50W solar panels should be wired in parallel ("+" to "+", "-" to "-") then connected to the "+" and "-" solar terminals of the solar controller
  • For charging a 24V battery or 24V battery bank: The 2 x 50W solar panels should be wired in series when "+" of one panel is connected to "-" of the other panel, and the remaining "+" and "-" leads should be connected to the "+" and "-" solar terminals of the solar controller respectively.

Tip: the 5m cable on each solar panel can be shortened as required (e.g. leaving 2m attached to the solar panel) and the remaining cable can be used between the solar controller and the battery / battery bank.

Please note this is an essentials kit and does not include brackets or battery cable. If you require these extra items, please purchase them separately. For example: this waterproof cable entry gland, a set of corner brackets for mounting on your roof and a 5m 2.5mm dual core battery cable with a fuse holder, fuse and ring terminals.

If your system requires a premium quality, long-life battery, we recommend our AGM or GEL deep-cycle batteries for your application.
