SPR-F 240W 12V EBL solar system for motorhomes, optional

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 flexible 120W SP-Ultra 12V high-end solar module from Offgridtec (efficiency >24%) ensure high yields. The stand-alone solar system is specially designed for motorhomes. Except for the batteries, it contains everything you need to install and operate the 12V solar system. In addition, the charge controller offers the option of connecting the solar system to the Schaudt electrical block (EBL) of the motorhome (EBL connection cable required). All components included in the set meet the highest quality standards.Set meet the highest quality standards.

Special features

• Flexible high-end solar modules equipped with American Sunpower cells and connected on the rear side. The module efficiency is more than 24%, which is well above average
• The SPR series Semi-Flex modules supplied are significantly smaller and lighter than comparable conventional solar modules with the same output. They can be bent up to a curvature of 30%
• Dual charge controller – innovative technology made in Germany enables the charging of living space and starter batteries.
• MPP tracker – Maximum Power Point Tracking ensures higher yields as the entire module voltage is tapped
• EBL-compatible – can be operated both on the Schaudt electrical block and directly on up to 2 different battery circuits

Daily yield: Average daily yield in summer from May to October: 960Wh daily (measured in northern Germany; the further south you are, the higher the yield you can expect)

2x Offgridtec® 120W high-performance solar module, flexible (back contact)
Semi-flexible monocrystalline 120W 12V high-end solar panel with rear-contacted high-power solar cells from the American manufacturer Sunpower – currently the best available with an efficiency of more than 24%. This product combines the world's best solar cells with the new back-contact process. The result is a high-end product at a reasonable price. In addition, during the production of this series, we took special care to ensure that the rest of the module was also worthy of these valuable cells. This panel is significantly lighter and smaller in size than conventional solar cells with the same output. The light yield in poor conditions is also higher with the SP series than with our normal mono series.
The modules are flexible up to a curvature of 30%. With a module length of 1 meter,this corresponds to a bendability of up to 30 cm measured from the center of the module. We recommend bonding the modules using the adhesive kit included, which contains individual thick adhesive strips. The module also has mounting lugs. Please refer to our user instructions for more information.

The Votronic MPP 250 Duo Digital solar charge controller
Highly efficient dual charge controller - charges service and starter batteries! Offers the option of connecting the photovoltaic system to the motorhome's electrical block. Using MPP technology, the controller automatically determines the maximum power output (MPP) of the solar modules several times per second. It then converts the excess voltage of the solar module into a higher charging current for the battery. Special high-frequency switching regulator technology with high efficiency makes this possible, ensuring shorter charging times and the best possible utilization of the solar system's power.

LCD solar computer S
the measured values are clearly displayed on the screen for easy control and use of the solar system at the touch of a button. The current solar power is always shown as a bar display, allowing you to check it at a glance. The display is backlit (switchable) and can be read very easily even from a distance and in all lighting conditions.

Cabling set
All necessary cables are already pre-crimped with specialist tools. This means you do not need to purchase special pliers for the solar connectors. The cable is 8 m long and has 2 wires á 6 mm²

Cable feed-through
Cable entries from the roof into the interior are always quite tricky, as it must be ensured that everything is absolutely watertight and remains so even after many years.
Even the smallest amount of water ingress can often cause irreparable damage to the interior insulation and furnishings. This is particularly true as moisture is often only noticed at a fairly late stage. This is why the roof feed-throughs were developed:
The housings are made of the same UV- and weather-resistant material as the mounting brackets offered in the online shop. They are extremely stable and absolutely slip-proof. The wide adhesive edge ensures optimal sealing.
The feed-throughs can be glued on using the adhesive set, which you also need to glue on the solar mounting brackets. The housings can also be painted in any color and thus adapted to the surface on which they are to be mounted.

Adhesive bonding

When used correctly, bonding is superior to screw connections in the harsh conditions of motorhome or boat use. On painted or GRP surfaces, a strength of over 4 N/mm2 can be achieved, which, calculated on the bonding surface, is a value that would never be achievable with a screw connection in the thin aluminum or GRP carrier layer. This adhesive set enables even a layman to create an absolutely secure connection between spoilers and the respective substrate.

The adhesive set contains all the components necessary for even DIYers to create a professional connection. Stainless steel screws for attaching the solar modules are included, as are detailed adhesive instructions. All you need is a standard hand lever press for cartridges and a lint-free cloth.

Individual modification requests are welcome on request
If you would like a different charge controller from our range, or if you would like the cables to be a different length, please feel free to contact us at any time. The color of the spoilers and the roof feed-through can also be changed from black to white. Simply send a short request for a quote to our customer service team, including the item number and your desired changes. Please contact customer service to find out about any costs that may be incurred.
