300W MPPT 12V Caravan Complete Set with EBL-Option

This solar set for self-sufficient power supply in a motorhome really leaves nothing to be desired. Innovative Mpp dual charge controller technology combined with the highly efficient 150w sp-Ultra high-end solar module fromOffgridtec(efficiency >24%) ensure high yields. The island solar system is specially designed for motorhomes. it includes everything you need to install and start up the Solarasystem, except for the batteries. Furthermore, the charge controller offers the possibility to connect the Solarasystem to the Schaudt electric block (ebl) of the motorhome (ebl connection cable required).all components included in the set meet the highest quality standards.

special features

The module can be unscrewed from the spoiler at any time, should you ever need to the surface under the solar module.

Also at the critical point, the cable grommet into the interior of the motorhome, we have paid attention to special quality. The supplied cable grommet is made of the same sturdy material as the roof spoiler for the solar modules and is simply glued on. The connection is absolutely waterproof and lasts for many, many years.

Offgridtec® 150w sp-Ultra high end solar panel

Monocrystalline 150w Hígh-End solar panel with back-contacted high-power solar cells from the American manufacturer Sunpower - currently the best that can be processed with an efficiency of almost 24%. This is where the world's best solar cells and the new back-contact process meet. The result is a high-end product at a solid price. In addition, we took special care in the production of this series to ensure that the rest of the module also does justice to the valuable cells. This panel is significantly lighter and smaller in area than conventional solar cells with the same output. Also, the light output under worse conditions is higher with the sp series than with our normal mono series.

Offgridtec® mppt Pro Duo charge controller 30a 12/24v

Highly efficient dual charge controller for charging the service and starter battery. offers the possibility to connect the photovoltaic system to the electric block of the motorhome. Using MPP technology, the controller automatically determines the maximum power output (mpp) of the solar modules several times per second. It then converts the voltage surplus of the solar module into a higher charging current for the battery. A special high-frequency switching controller technology with high efficiency makes this possible and thus ensures shorter charging times and the best possible power utilization of the Solarasystem.

Mounting & cabling

Roof spoiler mounting kit

Spoiler profiles are the first choice especially for caravans and motorhomes when it comes to a clean mounting of the 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). Due to the closed construction of the spoiler, no branches or similar can get caught under the solar modules.
Dimensions spoiler: l x w x h: 54.5cm x 8.9cm (of which approx. 3cm support surface module per spoiler) x 6.5cm

Cable grommet

Cable ducts from the roof into the interior are always quite tricky, because it must be ensured that even after years everything is absolutely tight and also remains tight. Even the slightest water ingress can often cause irreparable damage to the interior insulation and furnishings, especially as the moisture is often not noticed until quite late. For this reason, the roof penetrations were developed:
The housings are made of the same uv- and weather-resistant material as the mounting brackets offered in the online store. They are extremely stable and absolutely slip-proof. The wide adhesive edge ensures optimum sealing. The bushings can be glued on with the adhesive set that you also need to glue on the solar mounting brackets. The housings can also be painted as desired and thus adapted to the substrate on which they are to be mounted.

Wiring set

All necessary cables are already pre-crimped with specialized tools. So you don't need to buy special pliers for the solar connectors. The cable has a length of 8m and accommodates 2 cores á 6mm²

The bonding

A properly executed bonding is superior to any screw connection in tough motorhome or boat use. On painted or GRP surfaces, a strength of more than 4 N/mm2 can be achieved, this would be a value calculated on the glued surface, which could never be achieved with a screw connection in the thin aluminum or GRP carrier layer. This gluing set enables even a layman to create an absolutely firm connection between spoilers and the respective substrate.
The gluing set contains all the components necessary for even the do-it-yourself installer to create a professional connection. Stainless steel screws for fastening the solar modules are included as well as detailed bonding instructions. In addition, all you need is a standard hand lever press for cartridges and a lint-free cloth.
