Installation takes less than two hours—experienced hands can do it even faster. The expected daily output (April to October) averages 1200Wh/day (max. 2400 Wh on sunny days in Germany). The system is ideally suited for charging 12V AGM, GEL, or lead-acid batteries

300W motorhome complete set: simple, proven, high quality

The set contains all the components you need to charge your batteries on the go. What makes our solar systems for motorhomes special is that we use an extra-sturdy mounting system that can be easily glued on. The module can be unscrewed from the spoiler at any time if you need to access the area under the solar module. This set is designed so that it can be expanded with another module in the same performance class.

We have also paid particular attention to quality at the critical point where the cable enters the interior of the motorhome. The supplied cable feed-through is made of the same sturdy material as the roof spoilers for the solar modules and is simply glued on. The connection is completely watertight and will last for many, many years.

The Offgridtec PWM-PRO solar charge controller

The Offgridtec PWM-Pro 12V 30A charge controller series features a large, convenient LCD display and uses state-of-the-art charging technologies. A large display uses symbols to inform the user about all operating states. The charge status is visually displayed in the style of a fuel gauge. Data such as voltage, current, and charge status can also be displayed digitally as numbers on the display. In addition, the controller has a kWh meter that the user can reset themselves. A controllable load output and 2 USB 5V outputs are also integrated into the controller and supply your 12V and 5V DC consumers with power. Please refer to the charge controller documentation for the complete range of functions

Professional solar mounting system

Our ABS spoilers from Offgridtec are the ideal mount for your solar module when it comes to achieving the lowest possible weight with solid stability. The ABS plastic spoilers, available in black and white, offer an excellent solution for mounting solar panels on the roofs of motorhomes, caravans, or trailers. Thanks to their elegant appearance, the spoilers with a solar module not only offer functionality but also give your motorhome a rounded look. They have been aerodynamically shaped to keep noise levels and wind resistance as low as possible. The holes in the spoilers have been pre-drilled at the factory and come with matching stainless steel screws. The item also includes installation instructions for proper installation.
