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 provides a secure power supply and optimal yields. Three different options ensure a continuous supply. Charging from the mains when stationary, charging with the help of the charge booster while driving, and a 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 when installation space is limited and reduces the total weight to a minimum. The system is not only suitable for self-sufficient stationary use, but with its flexible solar panel it is also ideal for use on caravans and campers.

The electronic core – the Votronic VBCS Triple device combination

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

• Pb mains charger:Powerful charging of the on-board battery and supply of 12V consumers from the mains. 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 characteristics, the device can be permanently connected to the mains (use, winter break)
• VCC charging converter:The powerful charging booster enables the on-board battery to be fully charged while driving. It increases/decreases the voltage to the required level so that the on-board battery can be charged with the optimum charging characteristic. It completely compensates for line losses and strong voltage fluctuations in the alternator, as is often the case with Euro 6 vehicles. The 12V consumers supplied are protected against overvoltage and voltage fluctuations.
• MPP solar controller:The MPP charge controller ensures a 10-30% increase in charging current, shorter charging times, and the best possible utilization of your solar system's power. 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 combi panel from Votronic. Both displays allow the current output of the solar system to be reliably displayed, monitored, and controlled. The Jupiter panel also offers the options of a battery computer and water management.

Flexible solar power 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 motorhomes. 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-tech plastic ensures weight savings and, at the same time, high light transmission of max. 96%.

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

Optimal cabling – Manufactured by Offgridtec Kabelmanufaktur

The mTriple solar system is delivered according to the plug & play principle with all the connection cables required to commission the system. The cables are all manufactured in our in-house cable factory and offer optimal connection quality. The 8 m long connection cable from the module to the 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 fuses suitable for the system are also included.

Mounting hardware included

The complete system is supplied with all the mounting materials required for attachment to your vehicle. The Dekalin adhesive set, for bonding the solar modules to the vehicle roof, contains white adhesive, cleaning wipes, a wool wiper, and the Dekavator bonding agent. The Offgridtec roof feed-through 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 branch sockets for connecting the two modules in parallel.

Individual customizations

As with all our complete systems, individual customizations are also possible here. Please contact us! Any costs incurred can be requested from customer service.
