Offgridtec mTriple Flex L motorhome solar system with 2 x 160W 45/30/350 VBCS triple charger and 1247 charge control display

The mTriple Flex L solar systems provide the ideal power supply for your RV or camper. The combination of the VBCS Triple from Votronic and the ETFE-AL solar module from Offgridtec ensures a reliable power supply and optimal output. A continuous power supply is guaranteed through three different methods. Charging from the grid while parked, charging via the charge booster while driving, and a combination of the solar module and MPPT charge controller when the sun is shining. This combination of components and the semi-flexible solar module reduces the system’s total weight to a minimum, making it ideal for installation on campers or RVs.

The Electronic Core – the Votronic VBCS Triple Unit Combination

The VBCS Triple ensures your continuous power supply in three ways. With the 30A Pb mains charger, you can efficiently charge your battery from the mains while stationary. The 45A VCC charging converter allows you to charge the onboard battery while driving. The third option is charging with solar energy using the MPP solar controller for up to 350 Wp. The included temperature sensor ensures optimal charging of your batteries.

• Pb Mains Charger:Powerful charging of the onboard battery and powering of 12V loads from the mains. Full charging power is available worldwide across the universal range of 110 V AC–230 V AC without the need for manual switching, even with significant variations in the mains supply (undervoltage/overvoltage, sine waveform, frequency). Thanks to its long-term charging characteristics, the device can remain connected to the mains at all times (during use or winter storage).
• VCC Charging Converter:This high-performance charging booster enables the on-board battery to be fully charged while driving. It raises or lowers the voltage to the required level so that the on-board battery can be charged using the optimal charging curve. It fully compensates for line losses and significant voltage fluctuations from the alternator, which are common in Euro 6 vehicles. The 12V loads it supplies are protected against overvoltage and voltage fluctuations.
• MPP Solar Controller:The MPP charge controller provides a 10–30% increase in charging current, shorter charging times, and the best possible utilization of your solar system’s output. MPP technology automatically determines the maximum power output of the connected solar modules several times per second.

The complete system also includes either the Charge Control S display or the VPC Jupiter 200 combo panel from Votronic. Both displays allow you to reliably view, monitor, and control the current output of the solar system. The Jupiter panel additionally offers battery monitoring and water management capabilities.

Flexible Solar Power Supply – the Offgridtec 160W ETFE AL V2 Solar Panel

The semi-flexible ETFE-AL 160W V2 solar panel from Offgridtec (3-01-018435) is based on a groundbreaking material composition (aluminum-ETFE) and is equipped with highly efficient mono-cells. The output voltage is 18V DC, making it very suitable for a wide range of applications. It is also walkable and significantly more slip-resistant than its predecessors, making it the perfect choice for marine and mobile applications. Power is supplied by state-of-the-art solar cells that, thanks to the latest MONO-PERC technology, boast impressive cell efficiency and stand out from the crowd with low power degradation rates.

Optimal cabling – Manufactured at the Offgridtec cable factory

The mTriple solar system is delivered, in accordance with the plug-and-play principle, with all the connection cables needed to commission the system. The cables are all manufactured in our in-house cable factory and feature optimal connection quality. The 8-meter-long connection cable from the module to the charge controller allows for flexible installation, tailored to the on-site conditions. The battery cables feature an integrated MIDI fuse holder to protect the charge controller and the downstream equipment in the event of a short circuit or overcurrent. The fuses compatible with the system are also included.

Mounting hardware included

The complete system comes with all the mounting hardware needed to install it on your vehicle. The Dekalin adhesive kit, used to attach the solar modules to the vehicle roof, includes not only the white high-strength adhesive but also cleaning wipes, a lint-free cloth, and the Dekavator bonding agent. The Offgridtec roof feed-through establishes the connection between the solar module on the roof and the charge controller inside the vehicle. The version with two solar modules also includes a pair of junction boxes for connecting the two modules in parallel.
