This high-efficiency, waterproof 250W 12V monocrystalline solar panel is designed for permanent outdoor use to provide free electricity for charging 12V batteries. It can power various applications such as camper vans, motorhomes, boats, sheds, farms, remote telecommunications or monitoring equipment. It can also provide a direct power supply for applications not sensitive to changes in input voltage or current, such as electric motors or pumps.

The panel comes with 5m of special solar cable, allowing it to work at high roof temperatures with minimal power losses. It is fitted with a pair of male/female MC4 connectors for easy connection to other solar panels, existing systems, or 6mm extension cables.

Featuring long-lasting, high-efficiency monocrystalline solar cells and a tough, sealed aluminum frame, this panel ensures consistent, free power for many years, regardless of weather conditions. The panel also includes innovative 5-busbar solar cells, which are more efficient than traditional 2, 3, or 4-busbar solar cells, allowing them to extract more power from the same surface area. This results in a smaller overall solar panel, making it ideal for limited-space applications. Additionally, these solar cells operate well even in high ambient temperatures, making them suitable for warmer climates.

The kit comes with a 20A 12V/24V dual battery solar charge controller designed to charge and protect two batteries independently, with automatic cut-off to prevent overcharging. The controller uses PWM (Pulse Width Modulation) technology, increasing charge acceptance and prolonging battery life. It's ideal for caravans, camper vans, boats, or systems with two batteries or battery banks. The controller allows you to set the initial charging priority, automatically diverting power to the other battery once one is fully charged. The unit also has various protection functions, LED indicators, battery type selection, and a built-in temperature sensor for optimizing the charging process based on ambient temperature. An external remote temperature sensor with a 3m cable is recommended if the controller is placed far from the battery or if they are exposed to different temperatures. Please note that this essentials kit does not include mounting accessories or battery cable.
