Always ready with the OBD2 solar module!

The trickle battery is a crucial component in off-grid systems, where it stores energy and provides a reliable power supply, especially when no external power source is available. Its robust design and intelligent charging technology ensure a continuous power supply for various applications, such as lighting, communication, and security, even far from the main power supply.

The Bear Squat website subjected various chargers to extensive testing. In addition to conventional chargers powered by standard wall outlets, solutions for trickle charging without a direct wall connection – namely, those based on solar power – were also examined. In these tests, the OBD2 solar module proved highly successful and offered a number of notable advantages:

  • Simple installation: The solar panel is placed behind the windshield and connected via the OBD2 port, allowing for easy installation.
  • Using the OBD2 interface: The module uses the vehicle's OBD2 interface as a power source, ensuring broad compatibility.
  • Effective maintenance charge: With 13 watts, it delivers a constant, low charge even in favorable lighting conditions to keep the battery at a balanced level.
  • Dependence on lighting conditions: The effectiveness depends on the lighting conditions, with direct sunlight ensuring a stable charge.

The OBD2 solar panel is a practical solution for RV owners to maintain their batteries, especially during extended periods of inactivity or sporadic use. Its off-grid functionality allows for independent outdoor use, which is particularly helpful for those who enjoy exploring remote locations and rely on a dependable power supply. With this solar panel, batteries can be optimally maintained and preserved even in remote areas.

Pothole Rodeo 2018 – Solar power from Austria to the Black Sea and back to the Adriatic Sea

A road trip from Austria in a VW bus with solar panels on the roof, through Hungary, the Carpathian Mountains, and Moldova to the Black Sea. The return journey went via Bulgaria, Macedonia, Albania, Montenegro, and Bosnia, ending in Split.

On Saturday, July 7.7.2018, 1, after a long period of preparation, the day finally arrived: We set off in our orange VW T3 "Bulliver" (built in 1982, 50 hp, top speed: 90 km/h downhill) from Shopping City Seiersberg in Graz, Austria, simultaneously with 150 other junk car teams, embarking on our Balkan adventure, "Pothole Rodeo." The destination of our first leg was Novi Sad, the second largest city in Serbia. We crossed Hungary towards Croatia, and after a short transit, headed for Serbia. We were thoroughly searched at the Serbian border, but reached Novi Sad without any problems in the evening. The Danube metropolis greeted us with overcast skies and rain, so we ended the evening with a pleasant dinner.

Solar power makes it possible to have sufficient electricity even when you're on the go. Always have fully charged batteries, even far from home, thanks to a solar system. A solar panel charges the battery with a charge controller from SOLARA, even under the harshest conditions.

The second day started early: We tried to finish the first day's challenge (determining the engine displacement of all 150 participating team vehicles) in a rush and handed our results to the judge, who immediately presented us with the challenge for our second leg: In an envelope, we received 3 Romanian Leu (approx. €0,60). Our task was to obtain as many different fruits as possible from our trusted fruit and/or vegetable vendor. We set off northeast. Shortly after Timisoara, torrential rain suddenly began, and it wasn't long before a Romanian car in front of us completely wrecked. When we stopped to help, our VW bus showed its first signs of trouble: Due to the overload (blower, windshield wipers, hazard lights, etc.), the fan belt gave out, and we had to limp onto the hard shoulder. In heavy rain, we changed the rudder and continued to the next place where we could stop to dry off. Due to the time lost and the long distance still ahead, we chose the shortest route from there. Sighisoara (or Schäßburg) is the birthplace of Count Dracula and a romantically winding little town that we'll definitely be returning to. :)

Day 3 of our Balkan adventure began with rain. We set off towards Moldova, only to be greeted by some truly Moldovan potholes after a long wait at the border. Exactly what we had imagined the Balkans to be! ;) The day dragged on, as we (day challenge 3) delivered school supplies and toys to a childcare facility run by the organization ora. The joy of the caregivers, however, quickly made up for all the potholes. :) We arrived in Chisinau late in the evening and unfortunately only saw the Moldovan capital at night.

Solar systems with top test results provide power on the go. Mobile technology for charged batteries. Charge with solar power without a grid connection. A solar panel is easy to install and charges the battery with a charge controller from SOLARA.

Based on our latest observations regarding the quality of Moldovan roads, we planned our fourth leg so that we would take the shortest route back west to reach the good old Romanian country roads. We overtook countless families in horse-drawn carts, all of whom waved to us and were delighted when we wanted to take their picture. In the early evening, we finally reached the Black Sea, or more precisely, Constanta, our easternmost destination in these eight days, where we immediately plunged into the cold water. That evening, we dutifully fulfilled our daily challenge – drinking with locals – and were treated to several regional spirits by our new Romanian friends. ;)

We've always had solar power. Our solar system, designed for extreme travel, has achieved top test results, providing power on the go. Mobile solar technology has always ensured charged batteries. Charging with a solar panel is fantastic!

The final stage on day 8 finally took us through Bosnia to the beautiful Croatian city of Split, where we crossed the finish line and received our certificates.

The longest leg of our journey, at 750 kilometers, was finally our return home to beautiful Upper Austria.

Following the motto "Slow but steady," we were never the first to reach the finish lines, but the other teams were always happy to finally see our orange VW bus crawling up the mountain. ;) But: It's a rally, not a race.

Our conclusion: A fantastic adventure holiday with incredible experiences, places, and people! And who knows, maybe we'll be back next year when the search for Europe's last potholes continues… :)

Warm greetings from Team #106 Bullivers Reisen!

Self-build with SOLARA Vision modules

Ulrich Dolde owns an off-road camper and has expanded his solar capacity with SOLARA Vision modules. In his blog , he explains how he removed the old modules himself and installed the new SOLARA Vision modules on his roof!

After realizing that his 15-year-old modules were no longer generating sufficient power and were undersized at 200 Wp, he faced the decision of which new modules to install. Ultimately, he opted once again for the walkable glass-glass solar modules from SOLARA ( S-Series Vision ), which he had already installed on the roof of his cab in 2018. Despite their higher price and weight compared to conventional solar modules with a film backing, the SOLARA S-Series Vision was the best option for him.

The main reason for his decision was that he plans to park his vehicle for an extended period during his next trip to Asia while he flies home to continue his journey later. Given the possibility that someone might climb onto the roof while the vehicle is unattended, he wants to ensure that the new modules are robust enough to prevent any potential damage. SOLARA's glass-glass modules are particularly well-suited for this purpose.

These walk-on solar modules are distinguished by their German manufacturing and robustness. You can find the glass-glass solar modules here under SOLARA S-Series-Vision.

An interview with a managing director of SOLARA about the use of solar modules for off-road motorhomes

Camper:
Anyone wanting to optimize their camper's energy supply will need to install one or more solar panels. What question should you ask yourself first?

SOLARA:
Do I need to consider weight or height? This question usually clarifies whether I'm more inclined towards framed glass or flexible flat modules. And of course, there's the question of budget. Good flat modules are comparatively expensive.

Camper:
Then the next question is: How much total power do I need on the roof?

SOLARA:
Correct. As always, an honest energy consumption analysis is essential. Which appliances are running and for how long each day? This determines the required system. As a rule of thumb, our experience shows that 100 to 200 Wp is usually sufficient for campervans or panel vans, while larger motorhomes require 200 to 400 Wp as a basic setup.

Camper:
In principle, would a combination of glass and semi-flexible flat modules also be possible?

SOLARA:
Yes, absolutely. Many customers supplement glass modules with semi-flexible ones, or with a mobile folding module if additional glass modules would be too large.

Camper:
Which combinations would still be critical?

SOLARA:
It is not advisable to combine modules from different manufacturers or modules of different sizes, i.e., with different output voltages. A 100W module and a 150W module from the same manufacturer should also not necessarily be connected to the same speed controller.

Camper:
Is one large charge controller better than several small ones?

SOLARA:
Yes, for reasons of redundancy – several small ones are better, especially if different modules are used.

Camper:
A look at current problems?

SOLARA:
Van drivers are increasingly opting for semi-flexible flat modules. They look stylish and save weight. However, many unsuitable products are on the market, and a large number fail, requiring costly disassembly. Sometimes bending radii are exceeded, and sometimes soldered cell connectors break due to high thermal fluctuations. Solara uses elaborately soldered, flexible cell connectors and an aluminum sandwich panel as a base to better dissipate heat and prevent overbending. Those who fully bond modules should be aware that some water can always diffuse through them. Increased moisture under the module can freeze, and frost damage can destroy the cell.
