320W 12V dual battery solar kit for camper/boat with controller and cable

This waterproof, high-efficiency 320W 12V monocrystalline solar panel is designed for permanent outdoor use. It provides free electricity for charging 12V batteries, ideal for powering various applications in camper vans, motorhomes, boats, sheds, farms, as well as remote applications like telecommunications or monitoring equipment. Additionally, it can be used to directly power applications not sensitive to changes in input voltage/current, such as electric motors or pumps. The kit comes with a controller and cable.

The solar panel comes with 5m of special solar cable that can withstand high roof temperatures with minimal power losses. The cable is fitted with a pair of male/female MC4 connectors for easy connection to other solar panels, an existing system, or a 6mm extension cable (the MC4 connectors can also be removed for wiring to the screw terminals of the solar charge controller). The panel features long-lasting, high-efficiency monocrystalline solar cells and a durable, sealed aluminum frame for consistent, free power over many years. The waterproof design allows the panel to be used in all weather conditions. Additionally, the panel is equipped with innovative 5 busbar solar cells for greater efficiency and better performance in warm climates.

The kit includes a 20A 12V/24V dual battery solar charge controller designed to charge and protect two batteries independently, with automatic cut-off to prevent over-charging. The controller uses PWM (Pulse Width Modulation) technology to increase charge acceptance and prolong battery life. It is suitable for applications such as caravans, camper vans, boats, or other systems with two batteries or battery banks. The controller can work with only one battery and has many protection functions, including stopping reverse current at night, overcharge, short circuit, and reverse polarity. It also offers various LED indicators, battery type selection, and an RJ-45 socket for an optional remote LCD meter with a 10m cable. A built-in temperature sensor allows the controller to optimize the charging process based on ambient temperature. If the controller and battery are exposed to different temperatures, an external remote temperature sensor with a 3m cable is recommended.
