20a LCD MPPT 12v / 24v auto solar charge controller usb 5v

  • System voltage: DC12V / 24V Automatic Recognition
  • Rated current: 20A
  • USB: 5V 3A
  • Max. PV (Voc) input voltage: 100V DC (15A, 20A)
I-P-Wiser 1 series adopted with auto cool, high conversion efficiency, LCD display and free PC software. It features an efficient MPPT controlller Algorithm to track the maximum power point of the PV array in any environment. Greatly improve the utilization of the solar panel. Also added the output function (USB 5V 3A). Mppt controller Can be widely used in off-grid solar system, Communication base station solar system, household solar systems, street light solar systems, field monitoring and other fields.


1.High efficiency MPPT control algorithm, MPPT efficiency ≥ 99.5%, whole Machine conversion efficiency upto 98%; 
2.12V / 24V system Automatic Recognition, users can use it in different system conveniently. 
3. Maximum PV input voltage: 100VDC (15A, 20A), 150VDC (30A, 40A, 50A) 
4.Charge mode: three stages (fast charge, constant charge, floating charge). It prolongs service life of the batteries. 
5.Discharge mode: ON / OFF mode, PV voltage control mode. 
6.Recommended battery types: sealed lead acid, vented, gel, NiCd battery. Other types of the batteries can also be defined. 
7.Most information could be provided by LCD like: system type., PV input voltage, battery type, battery voltage, charging current, charging power, working status and so on. Also customer's information like company name, website and logo can be added Into Solar Eagle software. 
8.RS232 communication, we can offer communication protocol also, it's convenient for user's integration management. 
9.CE, RoHS, FCC certifications approved .. We can help clients to approve other certifications. 
10.2 years warranty. And 3 ~ 10 years extended warranty service also can be provided.
