160W dual battery solar kit for camper / boat (with 20A dual battery controller and 5m cable)

The kit includes a 160W monocrystalline solar panel with a 5m solar cable and MC4 connectors, as well as a 20A Photonic Universe dual battery PWM solar charge controller. The solar panel is waterproof and highly efficient, making it ideal for permanent outdoor use. It can provide free electricity to charge a 12V battery to power a wide variety of devices and electrical appliances. The durable monocrystalline solar cells and tough sealed aluminum frame ensure long-lasting and consistent power generation, regardless of weather conditions.

 The panel has 5m of special solar cable which can operate at high roof temperatures, with minimum power losses. A pair of male / female MC4 connectors are crimped on the end of the cable for easy connection to the 20A solar charge controller (MC4 connectors can also be cut off when wiring to screw terminals of a solar charge controller). Certainly! Here is the rewritten version of the text for better clarity and readability:

Each individual solar panel undergoes thorough testing to ensure the highest quality standards. It is labeled with a unique serial number for further quality control and increased warranty protection.

20A Solar Charge Controller: The 20A 12V/24V dual battery solar charge controller included in this kit is designed to charge and protect two batteries simultaneously. It has automatic cut-off to prevent over-charging. The controller uses PWM (Pulse Width Modulation) technology to increase charge acceptance and prolong the life of batteries. Additionally, PWM technology can recover some lost battery capacity. This solar controller is ideal for a caravan, camper van, boat, or any system with two batteries such as engine and leisure battery, or two battery banks. You can set the initial charging priority, for example, 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 automatically detect if there's only one battery connected and will pass 100% of the charging current to this battery. You can add a second battery later. The unit comes with various protection functions, such as stopping reverse current at night (from the battery back to the solar panel), overcharge protection, short circuit protection, reverse polarity protection, and more.

Other features include various LED indicators, battery type selection (sealed, gel, flooded), and an RJ-45 socket for an optional remote LCD meter with a 10m cable. A built-in temperature sensor enables the controller to optimize the charging process based on the ambient temperature. If you plan to position the controller far away from the battery, or if the battery and the controller are exposed to different ambient temperatures, it is recommended to use an external remote temperature sensor with a 3m cable. To connect to the screw terminals of the controller, the green connector block on the end of the remote temperature sensor cable should be cut off. Please note that this controller is not waterproof and should be used indoors.

Please note that due to our warehouse arrangements, the solar charge controller may be shipped from a different warehouse than the solar panels, and therefore may be delivered in a separate package. This product is covered by a 1-year warranty. The solar panel is covered by a 1-year workmanship warranty provided by Photonic Universe, and the solar charge controller is covered by a 1-year warranty provided by the manufacturer.

Additionally, the solar cells are guaranteed to produce at least 90% of nominal power in 10 years after purchase and at least 80% of nominal power in 25 years after purchase. This warranty is provided by the manufacturer of solar cells.

The kit includes a user manual for the solar charge controller (see Documents tab) which explains wiring, installation, and operations. If you need help with installation or have any technical questions, we provide FREE support. Please contact us by email or phone.
