Solar MPPT Controller Lumiax MC4010BT, 12-24V/40A, Bluetooth

Product detailed description

MPPT controller 40A for all available battery types with system voltage 12V or 24V and for PV panels with maximum output of 520W (12V) or 1040W (24V), with maximum input voltage of 100V and minimum input voltage 1V higher than the battery charging voltage. It is therefore also suitable for panels with system voltage 12V, which generate 16-18V at maximum load. This controller uses an internal converter to adjust the V-A characteristic of the current source - the solar panel - so that it is optimal for charging the battery. It can utilize energy from solar panels better than a PWM controller, which 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 source with higher voltage and lower current. For example, 18 V and 5 A is converted to 14.5 V/6.2 A. The conversion efficiency of the V-A characteristic is usually above 95%, so losses are minimal, and controllers can usually be adapted to different battery types to provide the most optimal charging. The integrated Bluetooth module (Solarlife app) can monitor operating status and parameters in real time.
Technical parameters:
System voltage 12 or 24 V, usable batteries: Pb AGM, Pb AGM GEL, Pb liquid, LiFePO4
Maximum power of the photovoltaic panel: 520 W (1040 W - 24 V) for maximum utilization of the controller. When using more powerful panels, full power will not be utilized, but the controller's function will remain preserved without damage.
Maximum PV panel voltage: 100 V (-20 °C), 90 V (+25 °C)
Min. PV panel voltage when using a 12V battery: 15.0 V
Max. charging current: 40A
Max. charging current: 30A
Self-consumption: <8mA (12V), <12mA (24V)
4-stage charging for Pb batteries only (CC, CV-boost, CV-float, CV-equalize)
CC = charging with full power of PV panels up to the set end-of-charge value (CV-boost)
CV-boost = charging for 1-2 hours after reaching a terminal voltage of 14-15 V (adjustable)
CV-equalize = charging with increased voltage to mix the liquid electrolyte - optional only for lead batteries with liquid electrolyte
CV-float = charging with maintenance voltage 13.0-14.5 V (adjustable), preset to 13.7 V
Battery type selection: liquid dielectric, AGM, AGMGEL, LiFePO4
LCD display for setting and monitoring operating parameters
Temperature compensation: -4.17 mV/K per cell during boost+equal charging
-3.33 mV/K per cell during float charging
