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

Product detailed description

MPPT 40A controller for all available battery types with system voltage 12V or 24V and for PV panels with maximum power 520W (12V) or 1040W (24V) with maximum input voltage 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 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, 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 to charge the battery from a source with higher voltage and lower current. For example, 18 V and 5 A will be converted to 14.5 V/6.2 A. The conversion efficiency of the V-A characteristic tends to be above 95%, so losses are minimal and regulators can usually be adapted to different battery types to provide the most optimal charge.

Technical parameters:

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