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 self-sufficient solar systems!

Votronic solar controllers of the "MPP" (Maximum Power Point) series with "IU1oU2" charging characteristic are connected as a link 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 converts the solar module's excess voltage into a higher charging current for the battery (realized by high-frequency switching regulator technology with high efficiency). This increased charging current ensures shorter charging times and the best possible power utilization of the solar system. The MPP solar controllers operate fully automatically, are maintenance-free, and offer the following functions:

Special features at a glance:

• MPPT charging (Maximum Power Point Tracking)
• CI-Bus connection: to display 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 support charging and charge maintenance (max. 1 A) of the vehicle starter battery (start) with protection against overcharging
• Measuring output for EBL: Enables the convenient use of a (solar) current indicator built into the electrical block to control the solar system
• Overcharge protection: Regulates the battery's charging current when there is too much solar power and the battery is full, and ensures the battery's charge level is as high as possible by immediately recharging it when power is consumed.
• Parallel/buffer operation : Compliance with charging regulations even when consumers are operating simultaneously.
• “IU1oU2” charging characteristic: Defined charging voltage increase (U1) prevents harmful acid stratification (lead) and ensures equalizing charging of the individual battery cells (lead and lithium), followed by automatic maintenance charging (U2).
• On-board power system filter: Trouble-free parallel operation with wind and motor generators, mains chargers, alternators, etc.
• The charging voltage is free of peaks and regulated in such a way that overcharging of the batteries is impossible.
• Connection for battery temperature sensor: Temperature sensor is absolutely necessary when the lithium characteristic curve is set!

The 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 operates using 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 converts the solar module's excess voltage into a higher charging current for the battery (achieved using high-frequency switching regulator technology with high efficiency). This increased charging current ensures shorter charging times and the best possible power utilization of the solar system.
As an additional feature, the charge controller offers the option of continuously charging the vehicle's starter battery via a secondary charging output. Note: A temperature sensor is required to charge a lithium-ion battery.
