Votronic solar charge controller MPP 360 CI - 1722

Votronic MPP360CI Solar Charge Controller up to 360 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 switchable 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
• AES switching output: Automatically switches refrigerators with "AES" from gas to 12 V operation when there is a continuous surplus of solar power.
• Overcharge protection: Regulates the battery charging current back when there is too much solar power and the battery is full, ensuring the highest possible state of charge of 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: Problem-free parallel operation with wind and engine generators, mains chargers, alternators, etc.
• The charging voltage is free of peaks and is regulated so that overcharging the batteries is excluded.
• Connection for battery temperature sensor: Temperature sensor absolutely necessary 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 from 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 constantly recharge the vehicle starter battery with a secondary charging output. Note: A temperature sensor is required to charge a lithium-ion battery.
