The MPPT controller uses an internal inverter to adjust the V-A characteristic of the current source-solar panel to be optimal for charging the battery. It can therefore use the energy from the solar panels much better than the PWM controller, which regulates charging only by pulse limiting the direct connection of 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 the higher voltage and lower current of the source. For example, it generates approx. 15 V and 10 A from 30 V and 5 A. The conversion efficiency of the V-A characteristic is over 95%, so losses are minimal and the regulators can usually be adapted to different types of batteries so that charging is as optimal as possible.


Technical parameters:

- system voltage 12 V – 24 V, usable batteries: Pb AGM, Pb AGM GEL, Pb liquid, LiFePO4
- max. output of PV panels: 520W (1040W-24V) for maximum use of the controller. When using a more powerful panel, the full power will not be used, but the function of the fegulator will be preserved without damage.
- max. PV panel voltage: 100V (-20°C), 90V(+25°C)
- max. charging current: 40 A
- max. load current: 30 A
- own consumption: <8mA(12V),<12mA(24V)
- 4 stage Pb battery charging (CC, CV – boost, CV – float, CV-equalize)
- CC = charging with the full power of the PV panels up to the set value of the end of charging (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 batteries with liquid electrolyte
- CV-float = charging with a maintenance 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 (maintenance)
- protection IP32
- RS485 interface
- operating temperature: –25°C~ 55°C
- dimensions: 189 × 255 × 69 mm
