120W 12V MPPT motorhome complete set EBL option

This solar kit for self-sufficient power supply in a motorhome truly leaves nothing to be desired. Innovative MPP dual charge controller technology combined with the highly efficient 120W SP-Ultra 12V high-end solar module from Offgridtec (efficiency >21%) 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 commission 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

• Solar generator consisting of absolute high-end solar modules equipped with American Sunpower cells and connected at the rear. The module efficiency is well above average at more than 21%
• The SPR series module supplied is significantly smaller and lighter than comparable conventional solar modules with the same output
• Dual charge controller – innovative technology made in Germany enables the charging of living space and starter batteries.
• MPP tracker – maximum power point tracking ensures greater yield as the entire module voltage is used
• 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: 480Wh daily (measured in northern Germany; the further south you are, the higher the yield you can expect)

The supplied components:

1x Offgridtec® SPR-100 120W 12V high-end solar panel
1x Votronic 1712 MPP 170 CI solar charge controller
1x Votronic LCD solar computer S
1x cable gland, single, suitable for the module connection cable supplied
1x Offgridtec 006550 55cm mounting profile, black – heavy-duty version
1x 8m Offgridtec 005095 professional connection cable - high-quality professional design for motorhomes
1x Offgridtec 1.5m 6mm² battery cable M8 with flat fuse holder, 30A fuse and pole terminals
1x mounting adhesive set with instructions and necessary accessories for pre-treatment
1x EBL cable set

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 cable feed-through supplied 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.

Offgridtec® SPR-100 120W 12V high-end solar panel

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 over 24%. This is where the world's best solar cells and the new back-contact process come together. 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 Votronic MPP 170 CI solar charge controller

With a maximum charging power of 170 watts and proven Maximum Power Point Tracking (MPP) technology, the charge controller maximizes the yield of your solar system by automatically determining the optimal operating point for the solar cells. This ensures efficient conversion of solar energy into electrical power, thereby optimizing charging efficiency.

LCD solar computer S

the measured values are clearly displayed on the screen and can be easily operated at the touch of a button for better control and use of the solar system. 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.

Roof spoiler mounting kit

Spoiler profiles are the first choice, especially for caravans and motorhomes, when it comes to clean mounting of 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). Thanks to the closed design of the spoilers, no branches or similar objects can get caught under the solar modules.
Spoiler dimensions: L x W x H: 54.5 cm x 8.9 cm (of which approx. 3 cm is the module contact surface per spoiler) x 6.5 cm

Cabling set

All necessary cables are already pre-crimped with specialist tools. This means you do not need to purchase special pliers for the MC-4 connectors. The cable is 8 m long and has two 4 mm² wires.

Cable feed-through

Cable feed-throughs 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 years of use.
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.
