The Offgridtec 300W Premium-L 12V (MPN 4-01-010960) is the perfect solar set for self-sufficient power supply in your motorhome or caravan and really leaves nothing to be desired. Installation takes less than two hours - practised hands are much quicker still. The expected daily output (April to October) is an average of 1200Wh/day (max. 2400 Wh on sunny days in Germany). The system is ideally suited for charging 12V AGM, GEL or lead-acid batteries.

300W complete motorhome set: simple, proven, high quality

The set contains all the components you need to charge your batteries on the move. The special thing about our solar systems for motorhomes: we use an extra-solid mounting system that can simply be glued on. The module can be unscrewed from the spoiler at any time should you ever need to access the area under the solar module. This set is designed so that it can be extended by another module in the same power class.

We have also paid special attention to the critical point, the cable feed-through into the interior of the motorhome. The cable grommet supplied is made of the same sturdy material as the roof spoiler for the solar modules and is simply glued on. The connection is absolutely watertight and will last for many, many years.

Important performance features

  • We are the only manufacturer to offer you a complete mobile home solar system in which all components are supplied from our own production - of course, as usual, in the highest Offgridtec quality.
  • The Premium-Mobile system class is probably the best-selling motorhome solar system on the market and has already been successfully installed thousands of times. In addition, the Premium-Mobile series established itself on the market more than 5 years ago and has been improved again and again on the basis of customer experience and constantly supplemented with technical innovations.
  • As a customer, you therefore benefit from a product that is highly mature and reliable.

Components of the Offgridtec 300W Premium L 12V

The Offgridtec PWM-PRO solar charge controller

The Offgridtec PWM-Pro 12V 30A charge controller series offers a large, convenient LCD display and works with the latest charging technologies. A large display informs the user about all operating states with the help of symbols. The state of charge is visually displayed in the manner of a fuel gauge. Data such as voltage, current and state of charge can also be shown digitally as a number on the display. In addition, the controller has a KWh counter that the user can reset himself. A controllable load output and 2 USB 5V outputs are also integrated into the controller and supply your 12V and 5V DC consumers with power. Please refer to the documentation of the charge controller for the complete range of functions.

The Offgridtec 300W V2 Solar Panel

Only monocrystalline solar cells of the highest quality are used in the production of our modules.  The module has a frame made of anodised aluminium and has specially hardened ESG solar glass, which makes it particularly resistant to external influences (weathering, etc.).

The expected daily output (April to October): on average 1200Wh/day (max. 2400 Wh on sunny days in Germany).
Solar module dimensions: 1350 x 590 x 35 mm

Professional Solar Mounting System

Our ABS spoilers from Offgridtec are the ideal brackets for your solar module when it comes to achieving minimal weight with solid stability. The ABS plastic spoilers, available in black and white, provide an excellent solution for attaching solar panels to the roofs of motorhomes, campers, or caravans. Due to their elegant appearance, the spoilers, when paired with a solar module, not only offer functionality but also contribute to a well-rounded look for your motorhome. To minimize noise level and wind resistance, they have been aerodynamically shaped. The spoiler holes come pre-drilled from the factory and include matching stainless steel screws. Additionally, the product includes an installation manual for proper setup.

Da sich auf meinem Camper Sicken befinden, wird die Befestigung am Dach mit dem Spoilern fast unmöglich. Welche Optionen gibt es für dieses Problem?
Wir bieten hierzu Sickenfüller an, die zwischen Dach und Solarmodul eingeklebt werden und so den Hohlraum ausfüllen. Die Höhe der Sickenfüller beträgt 5mm.
Eine weitere Möglichkeit wäre die enthaltenen Solarmodule z.B. gegen unsere ETFE-AL Serie auszutauschen.
Wenden Sie sich dazu am besten an [email protected]
Kann man statt der enthaltenen Solarmodule auch andere auswählen?
Gerne können wir auf Anfrage Ihren individuellen Änderungswünschen nachkommen. Wenden Sie sich dazu am besten per E-Mail an [email protected].
