Solar controller MPPT Lumiax MC4010, 12-24V/40A

MPPT regulator 40A for all available types of batteries with system voltage 12V or 24V and for PV panels with max. power 520W(12V) or 1040W(24V) with max. input voltage 100V and min. input voltage 1V higher than the battery charging voltage. It is therefore also suitable for panels with a system voltage of 12V, which generate 16-18V at maximum load. This regulator uses an internal inverter to adjust the V-A characteristic of the current source-solar panel to be optimal for battery charging. It can harness the energy from the solar panels better than a PWM controller that regulates charging only by pulse limiting the direct connection between the solar panel and the battery, where the pulse width is proportional to the state of the battery being charged. In other words, the MPPT controller can generate the ideal voltage and current for charging the battery from a higher voltage and lower current source. For example, 18V and 5A converts to 14.5V/6.2A. The conversion efficiency of the V-A characteristic tends to be above 95%, so losses are minimal and the regulators can usually be adapted to different types of batteries to provide the most optimal charging.

System voltage 12 or 24V , applicable batteries: Pb AGM, Pb AGM GEL, Pb liquid, LiFePO4
Max. power of PV panels: 520W (1040W-24V) for maximum use of the controller. When using more powerful panels, the full power will not be used, but the function of the controller will be maintained without damage.
Max. PV panel voltage: 100V (-20°C), 90V(+25°C)
Min PV panel voltage when using 12V battery: 15.0V
Max. charging current: 40A
Max.load current: 30A
Self-consumption: <8mA(12V),<12mA(24V)
4 stage charging-only for Pb batteries (CC,CV - boost, CV - float, CV-equalize)
CC = charging with full power of PV panels until the set value of the end of charging (CV-boost)
CV-boost = charging for 1-2hrs after reaching clamp voltage of 14-15V (adjustable)
CV-equalize= charging with increased voltage to mix liquid electrolyte - only selectable for lead acid batteries with liquid electrolyte
CV-float = charge with a holding voltage of 13.0-14.5V(adjustable), preset 13.7V
Battery type selection: liquid dielectric, AGM, AGM GEL, LiFePO4
LCD display for setting and monitoring operating parameters
Temperature compensation: -4.17mV/K charge during boost+equal charging
-3.33mV/K per cell during float charging
IP32 protection
RS485 interface
