Offgridtec mTriple Flex S motorhome solar system with 1 x 120W solar module 30/20/250 Votronic Triple Charger and 1247 Charge Control Display

The mTriple Flex S solar systems offer the ideal power supply for your motorhome or camper. The combination of the VBCS Triple from Votronic and the ETFE-SPR solar module from Offgridtec offers a reliable power supply and optimum yields. The permanent supply is ensured in three different ways. Charging in stationary mode from the grid, while driving with the help of the charging booster, and the combination of solar module and MPPT charge controller when the sun is shining.

The compact combination of the VBCS and the highly efficient flexible solar module is ideal where installation space is limited and reduces the overall weight to a minimum. The system is not only suitable for self-sufficient standing and with the flexible solar panel also predestined for use on caravan campers.

The electronic core - the Votronic VBCS Triple device combination

The VBCS Triple ensures your permanent power supply in three ways. With the 20A Pb mains charger, you can charge your battery efficiently from the mains while stationary. The VCC charging converter with 30A allows you to charge the on-board battery while driving. The third option is to charge with solar energy using the MPP solar controller for max. 250 Wp, while the temperature sensor supplied ensures that your batteries are optimally charged.

• Pb mains charger:Powerful charging of the on-board battery and supply of 12V consumers from the mains. The full charging power in the universal range of 110V/AC-230V/AC without switching is available worldwide even with large deviations in the mains supply (under/overvoltage, sine wave, frequency). Thanks to the long-term charging characteristic curves, the device can be permanently connected to the mains supply (use, winter break)
• VCC charging converter:The powerful charging booster enables the on-board battery to be fully charged while driving. It increases/reduces the voltage to the required level so that the on-board battery can be charged with the optimum charging characteristic. It fully compensates for line losses and strong voltage fluctuations of the alternator, which often occur in Euro 6 vehicles. The supplied 12V consumers are protected against overvoltage and voltage fluctuations.
• MPP solar controller:The MPP charge controller ensures a charging current gain of 10-30%, shorter charging times and the best possible power utilization of your solar system. The 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 100 combination panel from Votronic. Both displays can be used to reliably display, monitor and control the current output of the solar system. The Jupiter panel also offers the options of a battery computer and water management.

Flexible solar supply - the Offgridtec ETFE-SPR 120W solar module

The semi-flexible ETFE-SPR 120W solar module is a high-performance solar cell that is ideally suited for installation on a motorhome. The module made of ETFE plastic solar glass is slightly ribbed and can be walked on without hesitation when fully bonded, even when wet. The ETFE High-Tec plastic ensures weight savings and high light transmission of max. 96%.

• Output (Pmax): 120Wp
• Voltage (Vmp): 19.8V
• max. current (Imp): 6.05A
• Short-circuit current (Isc): 6.41A
• max. system voltage: 200V/DC
• Bendable: up to max. 30°
• Weight: 2.08 kg
• Dimensions: 540 x 1070 x 20 mm

Optimum cabling - manufactured in the Offgridtec cable factory

The mTriple solar system is supplied with all the connecting cables required to commission the system, in line with the plug & play principle. The cables are all manufactured in our in-house cable factory and feature optimum connection quality. The 8m long connection cable from module to charge controller allows for flexible installation, depending on the conditions on site. The battery cables have an integrated MIDI fuse holder to protect the charge controller and the technology behind it in the event of a short circuit or overcurrent. The appropriate fuses for the system are also included.

Mounting material included

The complete system is supplied with all the mounting material required to attach it to your vehicle. The Dekalin adhesive set for bonding the solar modules to the vehicle roof contains the white power adhesive, cleaning cloths, a wool wiper and the Dekavator bonding agent. The Offgridtec roof bushing creates 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 sockets for connecting the two modules in parallel.

Individual adaptations

As with all our complete systems, individual adaptations are also possible here. Talk to us! Please contact customer service for any costs that may be incurred.
