Votronic solar charge controller MPP 170 CI - 1712

Votronic MPP170CI Solar Charge Controller up to 170 W

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

Votronic solar controllers of the "MPP" (Maximum Power Point) series with an "IU1oU2" charging profile are connected as an intermediary between solar panel(s) and battery/batteries. With MPP technology, the controller automatically determines the maximum power output (MPP) of the solar modules continuously several times per second. It then converts the excess voltage of the solar module into a higher charging current for the battery (achieved through high-efficiency high-frequency switching regulator technology). This increase in 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:

Key features at a glance:

• MPPT charging (Maximum Power Point Tracking)
• CI-Bus connection: for displaying all relevant data on a central vehicle display
• 8 selectable charging profiles 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 maintenance charging (max. 1 A) of the vehicle starter battery (Start) with overcharge protection
• Measurement output for EBL: Enables the convenient use of a (solar) power display built into the electrical block to monitor the solar system
• Overcharge protection: Reduces the battery charging current in the event of excess solar power and a full battery, ensuring the highest possible state of charge for the battery by immediately recharging when power is consumed.
• Parallel/buffer operation: Adherence to charging requirements even when consumers are operating simultaneously.
• "IU1oU2" charging profile: Defined voltage increase (U1) prevents harmful acid stratification (lead) and ensures equalization charging of the individual battery cells (lead and lithium), followed by automatic maintenance charging (U2).
• Onboard network filter: Trouble-free parallel operation with wind and engine generators, mains chargers, alternators, etc.
• The charging voltage is free of peaks and is regulated to prevent overcharging the batteries.
• Connection for battery temperature sensor: Temperature sensor absolutely required when the lithium profile 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 by Votronic operates with the Maximum Power Point Tracking principle. With MPP technology, the controller automatically determines the maximum power output of the solar modules continuously several times per second. It then converts the excess voltage of the solar module into a higher charging current for the battery (achieved through high-efficiency high-frequency switching regulator technology). This increase in 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 to continuously recharge the vehicle starter battery with a secondary charging output. Note: A temperature sensor is required to charge a lithium-ion battery.
