Votronic Solar Charging Controller MPP 430 Duo Digital, 1725

Votronic's MPP 430 Duo Digital solar charge controller determines the maximum power output (MPP) of the solar modules several times per second. It then converts the voltage surplus of the solar module into a higher charging current for the battery. A special high-frequency switching regulator technology with high efficiency makes this possible and thus ensures shorter charging times and the best possible power utilization of the solar system.

    
Main charge output I: Automatic charge and charge maintenance of the (main) supply battery
Secondary charging output II: reduced current and voltage for recharging and maintaining the charge of the vehicle starter battery keeps it always ready to start
Stepless control, full batteries through immediate recharging when power is needed
Automatic charging program for gel, acid / wet, AGM / fleece and lithium batteries adjustable for optimal charging results
Very low own power consumption
Input for battery Temperature sensor for temperature compensation
Operating displays "AES", "Full", "> 80%", "MPP" and "Undervoltage"
Control output EBL, prepared for electric block with solar power indicator (harness type 2007 required)
Switching output "AES" (12V / 0.2A) with LED display: In case of strong solar power surplus, the automatic switch-off for Dometic / ELEKTROLUX refrigerators with "AES" (Automatic Energy Selector) causes from gas to 12V operation
