Solar Controller MPPT Lumiax MC2010, 12-24V/20A

Product detailed description

20A MPPT controller for all available battery types with system voltage of 12V or 24V and for PV panels with maximum power of 260W(12V) or 520W(24V), maximum input voltage of 100V and minimum 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 controller uses an internal inverter to adjust the V-A characteristics of the current source - the solar panel - so that it is optimal for charging the battery. It can make better use of the energy from solar panels than a PWM controller, which regulates charging only by pulse limitation of 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, 18V and 5A is converted to 14.5V/6.2A. The efficiency of the V-A characteristic conversion is usually above 95%, so losses are minimal and controllers can usually be adapted to different types of batteries to provide the most optimal charging possible.
Technical parameters:
System voltage 12 or 24V, usable batteries: Pb AGM, Pb AGM GEL, Pb liquid, LiFePO4
Maximum power of PV panels: 260W (520W-24V) for maximum utilization of the controller. When using more powerful panels, the full power will not be used, but the controller's function will remain intact without damage.
Maximum voltage of PV panels: 100V (-20°C), 50V(+25°C)
Min. voltage of PV panel when using a 12V battery: 15.0V
Max. charging current: 20A
Own consumption: <8 mA (12V), <12 mA (24V)
4-stage charging only for Pb batteries (CC, CV-boost, CV-float, CV-equalize)
CC = charging at 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 14-15V (adjustable)
CV-equalize = charging with increased voltage to mix the liquid electrolyte - optional only for lead-acid batteries with liquid electrolyte
CV-float = charging with maintenance voltage of 13.0-14.5V (adjustable), preset to 13.7V
Battery type selection: liquid dielectric, AGM, AGM GEL, 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
Protection IP32
Interface RS485
Operating temperature: -25°C~55°C
Dimensions: 136.6x136.4x67mm/0.9kg
Warning
A battery charge of at least 12.5V is required for Bluetooth pairing. SolarLifeBT application
12/24 versions can be switched via the Bluetooth interface using the Solarlife application. Turn on the controller with a 12V battery and connect via the application. In Battery param and Advanced settings, change the Rated voltage to 24V and select SEND, then disconnect the controller and reconnect it now with 24V. Everything should then be fine. Alternatively, you can change the Rated Voltage to AUTO, and it will again automatically detect 12 or 24V.
