MPPT regulator 15A for lead batteries with system voltage 12V and for PV panels with max. Output 200W with max. Input voltage 35V and min. Input voltage 15.8V. It is primarily intended for panels with a system voltage of 12V, which generate 16-18V at maximum load. This controller adjusts the characteristics of the current source-solar panel using the internal V-A converter so that it is optimal for charging the battery. It can therefore use energy from solar panels better than the PWM controller, which regulates charging only by pulse limitation of the direct connection of the solar panel and the battery, where the pulse width is proportional to the state of the charged battery. In other words, the MPPT controller can generate the ideal voltage and current to charge the battery from the higher voltage and lower current of the source. For example, 18V / 5A converts to 14.5V / 6.2A. The V-A conversion efficiency is usually over 95%, so losses are minimal and controllers can usually be adapted to different types of batteries so that charging is as optimal as possible.


Technical parameters:

- system voltage 12V
- max. power of PV panels: 200W for maximum use of the controller. When using a more powerful panel, the full power will not be used, but the function of the controller will remain without damage.
- max. output voltage of the PV panel: 35V
- minimum output voltage of the PV panel: 15.8V - verified by own measurement
- max. charging current: 15A
- max. discharge current: 10A (only if the load is connected via a controller)
- own consumption: 7mA
- 4-stage battery charging (CC, CV - boost, CV - float, CV-equalize)
- CC = charging at full power of the PV modules to the set end-of-charge value (CV-boost)
- CV-boost = charging for 1-2 hours after reaching terminal voltage 14-15V (adjustable)
- CV-equalize = increased voltage charging for liquid electrolyte mixing-optional only for liquid electrolyte batteries
- CV-float = charging with maintenance voltage 13.5–13.8V (adjustable)
- choice of Pb battery type: With liquid dielectric, AGM, AGM GEL
- not suitable for Li-Ion, LiFePO4 or Li-Pol batteries
- load disconnection at battery voltage 10.8–11.8V - adjustable
- LCD display for setting and monitoring operating parameters
- 2 × USB interface
- Temperature compensation: -4.17mV / K per cell when charging boost + equal -3.33mV / K per cell when charging float (maintenance)
- Modbus protocol based on RS-485 interface maximizing communication possibilities.
- IP32 protection
- operating temperature: -25 ° C ~ 55 ° C
- dimensions: 189 × 96 × 53mm / 0.42kg
