Description :


20A 12V/24V  MPPT PV Solar Charge Controller Regulator 15%-30% More Power High Efficiency

This solar charge controller uses the most advanced Maximum Power Point Tracking (MPPT) technology to  track the maximum power voltage point of solar panels as it varies depending on sunlight exposure and temperature. 

This technology ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers.


Features:

  • Increases charge efficiency by 20% - 43%
  • High technology MPPT with LCD display, efficiency > 98%
  • Employs a DC converting circuit, conversion efficiency > 96%
  • MPPT demo displays the efficiency of this controller compared to PCM models
  • Functions as a power meter
  • LCD display shows the battery voltage, charging current, charging power, output status, output mode, time and accumulated   power saving
  • Suitable for a wide range of batteries
  • Maximum charge and discharge current 20A
  • Five output modes: Manual,Standard,Timer,Light sensor,Light sensor on + Timer off.
  • Built in timer, suitable for a periodic discharge system such as solar street   lights, solar pumps etc.

FAQ
Q: What is MPPT? A: MPPT or Maximum Power Point Tracking is algorithm that included in charge controllers used for extracting maximum available power from PV module under certain conditions. The voltage at which PV module can produce maximum power is called ‘maximum power point’ (or peak power voltage). Maximum power varies with solar radiation, ambient temperature and solar cell temperature.
Q: What kind of battery can be used? A: Gel battery and lead-acid battery. Aluminium battery also suitable, but it needs to change setting and only apply for bulk order.
Q: Can it charging 12v battery system by 24v solar panel? A: Yes, no problem.
Q: How to connect & disconnect it with solar panel, load and battery. A: connect sequence: Battery(1st)-Load(2nd)-Solar panel(3rd). disconnect sequence: Solar panel(1st)-Battery(2nd)-Load(3rd).
Q: What's max solar input? A: 50v. over it will be short circuit.
Q: Why the voltage is too high? A: Supposed you charge 12v battery, then you need to make sure the panels are connected in parallel to get 18V.
