The solar charge controller is specifically designed for use in motorhomes and caravans and for Suitable for all lead-acid battery types and brands (wet, GEL/dryfit, and AGM/fleece batteries). Intelligent microprocessor control ensures optimal charging of the batteries using IU1oU2 charging curves. The solar charge controller operates fully automatically and maintenance-free and offers the following functions: Auxiliary battery charging output I, with a choice of 4 charging programs depending on the battery type; Starter battery charging output II: Separate auxiliary charging output with reduced charging current (24 V / 0.8 A) for trickle charging and maintaining the charge of the vehicle's starter battery, with overcharging protection during extended periods of inactivity. The charging voltage is free of spikes and regulated to prevent overcharging. Two battery charging outputs: Automatic charging of the main or auxiliary battery (Auxiliary Battery I). Trickle charging and maintenance charging of the vehicle starter battery (Start II) with overcharge protection. Unattended charging: Standard protection against battery back-discharge (in case of insufficient solar power, e.g., at dusk, at night, etc.), overload, and overheating. Buffer operation: Adherence to the charging curves even when simultaneously operating consumers connected to the battery. Overcharge protection: Reduces the battery charging current when solar power is too high and the battery is full, and ensures the highest possible state of charge when power is being drawn by immediately recharging. "IU1oU2" charging curve: Defined charging voltage increase (U1) prevents harmful acid stratification and ensures equalization of the individual battery cells, followed by automatic maintenance charging (U2). On-board power supply filter: Integrated, allows trouble-free parallel operation of the regulator with other charging sources, wind and gasoline generators, mains chargers, alternators, etc., on a single vehicle electrical system.
