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 gain 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:\u003c\/p\u003e \u003cp\u003e\u003cb\u003eFeatures at a glance:\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\n\u003cstrong\u003eMPPT\u003c\/strong\u003e charging (Maximum Power Point Tracking)\u003c\/li\u003e \u003cli\u003e\n\n\u003cstrong\u003eCI-Bus\u003c\/strong\u003e connection: for displaying all relevant data on a central vehicle display\u003c\/li\u003e \u003cli\u003e\n\n\u003cstrong\u003e8 switchable charging characteristics\u003c\/strong\u003e for lead, gel, AGM and LiFePO4 batteries\u003c\/li\u003e \u003cli\u003e\n\n\u003cstrong\u003eTwo battery charging outputs:\u003c\/strong\u003e Automatic charging of the main supply battery (12V) as well as support charging and trickle charging (max. 1 A) of the vehicle starter battery (Start) with overcharge protection\u003c\/li\u003e \u003cli\u003e\n\n\u003cstrong\u003eMeasurement output for EBL: \u003c\/strong\u003eEnables convenient use of a (solar) current display built into the electrical block to monitor the solar system\u003c\/li\u003e \u003cli\u003e\n\n\u003cstrong\u003eAES switching output\u003c\/strong\u003e: Causes refrigerators with \"AES\" to automatically switch from gas to 12 V operation when there is a consistently abundant solar power surplus.\u003c\/li\u003e \u003cli\u003e\n\n\u003cstrong\u003eOvercharge protection:\u003c\/strong\u003e Reduces the battery charging current if there is too much solar power and the battery is full, ensuring the highest possible battery charge level through immediate recharging when power is consumed.\u003c\/li\u003e \u003cli\u003e\n\n\u003cstrong\u003eParallel\/buffer operation\u003c\/strong\u003e: Compliance with charging regulations even when consumers are operating simultaneously.\u003c\/li\u003e \u003cli\u003e\n\n\u003cstrong\u003e\"IU1oU2\" charging characteristic:\u003c\/strong\u003e 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).\u003c\/li\u003e \u003cli\u003e\n\n\u003cstrong\u003eOn-board network filter:\u003c\/strong\u003e Problem-free parallel operation with wind and engine generators, mains chargers, alternators etc.\u003c\/li\u003e \u003cli\u003eThe charging voltage is free of spikes and regulated in such a way that overcharging of the batteries is impossible.\u003c\/li\u003e \u003cli\u003eConnection for battery temperature sensor: Temperature sensor is absolutely \u003cstrong\u003enecessary\u003c\/strong\u003e when the lithium characteristic is set!\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eVotronic MPP charge controllers are manufactured in Germany and are among the most powerful and reliable charge controllers on the market.\u003cbr\u003e The MPP series from Votronic works with the Maximum Power Point Tracking principle.
