This solar set for self-sufficient power supply in a motorhome from Offgridtec fulfils all requirements at the highest level. The innovative Mpp dual charge controller technology, paired with the extremely efficient 120W SP-Ultra 12V high-end solar module from Offgridtec (efficiency >21%), guarantees maximum yields. Specially designed for motorhomes, the off-grid solar system contains everything needed to install and commission the 12V solar system, apart from the batteries. In addition, the charge controller enables the solar system to be seamlessly integrated into the motorhome's Schaudt electrical block (EBL). Every component included in the set fulfils the highest quality standards.

Our solar kit provides everything you need to charge your batteries on the move. What makes our motorhome solar systems so special is that we use a particularly robust mounting system that can simply be stuck on. The module can be easily unscrewed from the spoiler if you ever need access to the area under the solar module. This set is designed so that it can be easily extended with another module in the same power class.
We have also placed particular emphasis on quality when it comes to the critical cable feed-through into the interior of the motorhome. The cable gland supplied is made from the same sturdy material as the roof spoiler for the solar modules and can simply be glued on. The connection is absolutely watertight and will last for many years.
Offgridtec® 120W SP-Ultra 12V high-end solar module
Our monocrystalline 120W/12V high-end solar panel offers back-contacted high-power solar cells from the renowned American manufacturer Sunpower - the best technology currently available with an efficiency of over 21%. This panel combines the top performance of the world's best solar cells with the advanced back-contact process. The result is a high-end product at an attractive price. When producing this series, we focussed on ensuring that every detail of the module corresponds to the high-quality cells. In addition, this panel is significantly lighter and more compact than conventional solar modules with comparable performance. Even in poorer light conditions, the SP series achieves a higher output than our conventional mono series.

LCD-Solar-Computer S
The measured values are clearly presented on the display and can be easily operated at the touch of a button for better control and utilisation of the solar system. The current solar power is also always shown as a bar graph, allowing you to check at a glance. The display is backlit (switchable) and is also very easy to read from greater distances and in all lighting conditions.
Roof spoiler assembly set
Spoiler profiles are the first choice for caravans and motorhomes in particular when it comes to neatly mounting solar modules. If the modules are mounted in the direction of travel, wind noise is no longer an issue (this also applies to alcove vehicles). The closed design of the spoiler also means that no branches or similar can get caught under the solar modules.
Spoiler dimensions: L x W x H: 54.5cm x 8.9cm (including approx. 3cm module support surface per spoiler) x 6.5cm
Cabling set
All necessary cables are already pre-crimped with specialised tools. So you don't need to buy any special pliers for the solar plugs. The cable has a length of 8m and contains 2 wires of 6mm² each
Cable bushing
The cable feedthroughs from the roof to the interior must be absolutely tight to prevent long-term damage to the insulation and furnishings. Our roof ducts are made of robust, UV and weather-resistant material, which is also used for the mounting brackets. They offer maximum stability, slip resistance and optimum sealing with a wide adhesive edge. The grommets can simply be glued on using the same adhesive set as for the mounting brackets and can be painted to match the desired surface if required.
The bonding
A correctly executed bond is superior to a screw connection in the demanding use of motorhomes or boats. A strength of over 4 N/mm2 can be achieved on painted or GRP surfaces, which would not be possible with a screw connection in the thin aluminium or GRP layer. Our adhesive kit enables even non-professionals to create a strong connection between spoilers and the substrate.
The adhesive kit contains all the necessary components so that even DIY enthusiasts can create a professional connection. Stainless steel screws for attaching the solar modules are included, as are detailed bonding instructions. In addition, all you need is a standard hand lever press for cartridges and a lint-free cloth.
Individual change requests on request
If you prefer a different charge controller from our range or cables in a different length, please do not hesitate to contact us. We will be happy to discuss your individual requirements. It is also possible to change the colour of the spoiler and the roof bushing from black to white. All you need to do is send a brief enquiry to our customer service team with the item number and change request. You can enquire about any costs directly with customer service.
