250W 12V solar charging kit with 20A controller and 5m cable

This 250W 12V monocrystalline solar panel is designed for outdoor use to charge 12V batteries for various applications, such as in camper vans, motorhomes, boats, sheds, farms, and remote locations like telecommunications or monitoring equipment. It can also provide power for applications not sensitive to input voltage/current changes, such as electric motors or pumps. The panel comes with 5m of special solar cable and male/female MC4 connectors for easy installation. The monocrystalline solar cells and sealed aluminum frame ensure durability and consistent power output in all weather conditions. The kit includes a 20A 12V/24V solar charge controller with PWM technology and various protection functions. The controller can handle up to 320W of solar power (12V system) or 640W of solar power (24V system). Additionally, the controller offers advanced communication technology for monitoring and programming parameters through a remote meter with an LCD screen, Wi-Fi module, or an RJ45 to USB cable for connection to a PC/laptop.

Using one of these communication methods, users will gain access to various charging parameters such as voltage, current (separately for solar panel/load), battery state of charge, accumulated charge and discharge energy, min/max voltage, and other information. If required, users will also be able to adjust the battery type and capacity, set charging volts for different charging stages, specify the duration of each charging stage, create a user-defined battery type with charging parameters specific to their battery (if the pre-existing options are unsuitable), personalize the 'load' settings (e.g. set timers for lighting, fans, pumps), and more. In addition to the built-in temperature sensor, the controller has a pair of terminals for connecting a remote temperature sensor, which can be attached directly to the battery to measure the battery temperature more precisely and optimize the charging process. 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.

Please note: Due to our warehouse arrangements, the solar charge controller may be shipped from a different warehouse to the solar panels and therefore delivered in a separate package. This product is covered by a 1-year warranty provided by Photonic Universe (including a 1-year warranty for the solar charge controller and a 1-year workmanship warranty for the solar panels). We will repair or replace defective items at our discretion. In addition, 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 the solar cells.

For installation advice, please click on the Installation tab. Electrical connection: the solar charge controller included in this kit is supplied with a detailed user manual which contains a wiring diagram and explains installation/operations. Please ensure that you read the full user manual before starting the installation. Fitting: the solar panel in this kit can be fitted to a flat roof using metal brackets, plastic brackets, or a variety of other methods. To view our full range of brackets, please visit the mounting accessories category of our online shop. The solar charge controller in this kit is not waterproof and should be mounted indoors.
