Votronic Solar Charge Controller MPP 170 CI - 1712

Votronic MPP170CI Solar Charge Controller up to 170 W

Effective battery charging for motorhomes, caravans, boats and off-grid solar systems!

Votronic "MPP" (Maximum-Power-Point) series solar controllers with "IU1oU2" charging characteristic are connected between the solar panel(s) and battery(ies). With MPP technology, the controller automatically determines the maximum power output (MPP) of the solar modules several times per second. It then transforms the voltage surplus of the solar module into a higher charging current for the battery (achieved through high-frequency switching regulator technology with high efficiency). This increase in charging current ensures shorter charging times and the best possible utilization of the solar system's power. The MPP solar controllers operate fully automatically, are maintenance-free and offer the following functions:

Features at a glance:

• MPPT charging (Maximum Power Point Tracking)
• CI-Bus connection: for displaying all relevant data on a central vehicle display
• 8 switchable charging curves for lead, gel, AGM and LiFePO4 batteries
• Two battery charging outputs: Automatic charging of the main supply battery (12V) as well as trickle charging and charge maintenance (max. 1 A) of the vehicle starter battery (start) with overcharge protection
• Measuring output for EBL: Enables convenient use of a (solar) current display built into the electrical block to monitor the solar system
• Overcharge protection: Reduces the battery's charging current in case of too much solar power and a full battery, ensures the highest possible battery charge level by immediate recharging when power is consumed.
• Parallel/buffer operation: Compliance with charging regulations even when consumers are operating simultaneously.
• "IU1oU2" charging curve: Defined charging voltage increase (U1) prevents harmful acid stratification (lead) and ensures equalization charging of individual battery cells (lead and lith.), followed by automatic trickle charging (U2).
• On-board network filter: Problem-free parallel operation with wind and engine generators, mains chargers, alternators, etc.
• The charging voltage is free of peaks and regulated so that overcharging of the batteries is impossible.
• Connection for battery temperature sensor: Temperature sensor absolutely necessary when Lithium curve is set!

Votronic MPP charge controllers are manufactured in Germany and are among the most powerful and reliable charge controllers on the market.
The MPP series from Votronic works with the Maximum Power Point Tracking principle. With MPP technology, the controller automatically determines the maximum power output of the solar modules several times per second. It then transforms the voltage surplus of the solar module into a higher charging current for the battery (achieved through high-frequency switching regulator technology with high efficiency). This increase in charging current ensures shorter charging times and the best possible utilization of the solar system's power.
As an additional feature, the charge controller offers the possibility of constantly charging the vehicle starter battery with an auxiliary charging output. Note: A temperature sensor is necessary for charging a lithium-ion battery.
