Self-sufficient solar power system, compactly designed for your Mercedes-Benz Marco Polo with pop-up roof, suitable for Marco Polos with electric pop-up roof or manual pop-up roof, with or without sunroof.

Our solar system for the Mercedes-Benz Marco Polo is also suitable for models from 2020 onwards with Mercedes-Benz MBUX and MBAC system. Our system works independently of the MBAC system. Voltage, current, charge, etc. are displayed and logged in the solar charge controller app, just like in vehicles without the Mercedes-Benz MBAC system. In the MBAC system, you can then see the battery voltage and the capacity / charge of the starter and body battery as usual.

As an option to our 125 watt solar system for the Mercedes-Benz Marco Polo, we recommend installing a lithium battery and a charging booster, so that you are travelling with significantly more capacity and the body battery is always charged while driving until it is full.

With our 110 watt solar system, you are self-sufficient when travelling in summer. The solar system is designed so that the refrigerator can always run at level 2 or 3 and you can charge various devices via the 12-volt and USB sockets, provided your Marco Polo is parked outside. When the body battery is fully charged, the solar charge controller also charges the starter battery and the buffer battery under the passenger seat in the Mercedes-Benz Marco Polo.

In practice, all 3 batteries are fully charged by mid-morning in summer.

- A solar panel with 125 Wp output is glued directly to the Marco Polo pop-up roof and grouted after drying, see photo.

- The height of the Mercedes-Benz Marco Polo is not increased. The solar panels are only 4 mm thick, including adhesive and silicone, so there are no restrictions in the garage, underground car park or multi-storey car park.

- The use of car washes is no problem with the solar system on your Mercedes-Benz Marco Polo.

- Roof racks, whether Thule, Westfalia or others, can still be mounted on your Mercedes-Benz Marco Polo pop-top roof.

- The solar panels are almost invisible around the Mercedes-Benz Marco Polo, see photos.

- The cable connection from the solar panel to the interior of the Mercedes-Benz Marco Polo is made via 1 hole in the pop-up roof, the cable is laid flexibly in the pop-up roof and goes exactly into the vehicle interior where the cable for the LED lamps from Westfalia is also laid, see photos.

- The solar Bluetooth charge controller with MPP technology achieves optimum output from the solar modules and protects the batteries (battery life cycle, 3-stage charging).

- By positioning the roof of your Mercedes-Benz Marco Polo, optimum conditions are created to maximise the yield of solar energy.

- A smartphone app (Apple & Android) is used to monitor and adjust the performance of the solar system, so no space is wasted in the Marco Polo for solar display monitors

- The solar system does not generate any wind noise, even when travelling at speeds of up to 200 km/h.

- All components are assembled by us and tested many times.

- The solar system charges the body battery of the Mercedes-Benz Marco Polo, when this has reached a sufficient voltage value, the starter battery and the buffer battery of the Mercedes-Benz Marco Polo are additionally charged with 3A.

- This solar system for Mercedes-Benz Marco Polo is only offered including installation by our workshop.

- We need your vehicle for three working days for this installation to dry the adhesive and the silicone and sealing compound joints.

- Please deliver your Mercedes-Benz Marco Polo freshly washed and dried to ensure that the roof only needs to be degreased.

- compatible with Mercedes-Benz Marco Polo / Horizon / Activity / Viano Marco Polo from 2004 onwards

Please also note our 250 Watt solar system for the Mercedes-Benz Marco Polo.
