MPPT regulator 20A for all available types of batteries with a system voltage of 12V or 24V and for PV panels with a max. output of 260W(12V) or 520W(24V) with a max. input voltage of 55V and a 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 voltage.
This regulator, using an internal converter, adjusts the V-A characteristic of the current source-solar panel to be optimal for battery charging.
It can utilize the energy from the solar panels better than a PWM regulator that regulates the charge only by pulse limiting the direct connection between the solar panel and the battery, where the pulse rate is proportional to the state of charge of the battery.
In other words, the MPPT regulator can generate the ideal voltage and current for charging the battery from the output voltage and lower current of the power supply.
For example, it converts 18V and 5A to 14.5V/6.2A.
The V-A conversion efficiency of the characteristic is over 95%, so losses are minimal and the regulators can usually be overdriven with a different battery type to give the best possible charge.
Can be controlled by mobile phone via the Solar Life app (for iOS and Android).
For correct pairing using Bluetooth, it is necessary to have a charged battery of at least 12.5V.
Specifications:
System voltage 12 or 24V, batteries that can be used: Pb AGM, Pb AGM GEL, Pb liquid, LiFePO4.
Max. PV panel power: 260W (520W-24V) for maximum use of the regulator.
When using higher power panels, full power will not be used, but the function of the regulator will be maintained without damage.
Max. PV panel voltage: 55V (-20°C), 50V(+25°C).
Min. voltage of PV panel when using 12V battery: 15,6V.
Max. charging current: 20A.
Self-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 set value of the end of charge (CV-boost).
CV-boost = charging for 1-2hrs after reaching a clamp voltage of 14-15V (adjustable).
CV-equalize= charging by increasing the voltage to mix the liquid electrolyte-optional only for lead acid batteries with liquid electrolyte.
CV-float = charging with a maintained voltage of 13.5-13.8V (adjustable).
Choice of battery type: With liquid dielectric, AGM, AGM GEL, LiFePO4 LCD display for setting and monitoring operating parameters.
Temperature compensation: -4.17mV/K per cell when charging boost+equal, -3.33mV/K per cell when charging float (maintained).
