• WATTSTUNDE WLR-BT 20.90 MPPT Charge Controller with LCD Display
• WATTSTUNDE® HXE mounting corners incl. stainless steel screws
• WATTSTUNDE® DX2 Solar Roof Feedthrough
• Dekalin adhesive set - white
• 2 x 7m solar connection cables 4mm² incl. compatible MC4 connector system (solar module to charge controller)
• MC4 connector set (socket + plug) already pre-assembled
• 1.5m battery connection cable 4mm² incl. 20A blade fuse
• Operating instructions for all devices in German

The complete kits in the WATTSTUNDE® series are characterized above all by their high quality and provide you with a sense of security and independence from the public power grid while on the go. The 190W complete kit contains only high-quality and reliable components and everything you need to begin installation and mounting on your motorhome roof immediately.

Easy installation, quick setup and pre-prepared materials make your assembly a breeze!

WATTSTUNDE DAYLIGHT solar modules are equipped with back-contact Sunpower cells, which have a significantly higher cell efficiency, up to 22%, than standard monocrystalline or polycrystalline solar modules, thus ensuring a higher energy yield! Thanks to back-contact technology, the cell can absorb more light and convert this additional energy into electrical energy.

These modules are unique due to their exceptionally high light output!

The included mounting spoilers are made of solid plastic and, thanks to their aerodynamic shape, prevent any driving noise.

The construction adhesive included in the set is a one-component elastic adhesive, specifically designed for this application.
The special chemistry enables reliable and durable bonding, thus reliably and permanently fixing the module to the vehicle roof.

Maximum yields thanks to intelligent MPPT technology

The new WLR-BT series from WATTSTUNDE® works with the Maximum Power Point Tracking principle.
With MPP technology, the controller determines the optimal operating point of the solar modules several times per second.
It can thus transform the excess voltage from the solar modules into an increased charging current for the battery. This increased charging current ensures shorter charging times and the best possible utilization of the solar system's power output.
Compared to simple PWM charge controllers, this makes it possible to achieve additional yields of up to 30%, especially under overcast skies or other unfavorable lighting conditions (high proportion of diffuse light).
The integrated LCD display allows you to keep an eye on the system at all times.

Together with the DAYLIGHT back-contact solar modules and the MPP charge controller, you receive an efficient premium set with high-quality products for maximum energy yield.

Enjoy your freedom with the high-quality motorhome solar systems from WATTSTUNDE®
