12V 24V 36V 48V MPPT 40A Solar Charge Controller with LCD

  • Model:I-P-eSmart3 series
  • System Voltage: DC12V/24V/36V/48V Automatic Recognition
  • Rated Current: 40A
  • Maximum PV(voc) Voltage: 130V
eSmart3 series is the third generation of eSmart mppt controller, combined with the second generation of high conversion efficiency, back-light LCD display, control mode, connect way, internal structure etc. features, also optimized the following points:
1.Increase all kinds of protection function to be used more reassuring.
2.Add the LOAD sampling to be used more clear of output load.
3.Wider PV Input voltage than eSmart2, so it suitable for more kinds of PV modules
4. Reduce the static standby self-consumption, energy saving and more simply for small system.
Choose eSmart3, more intelligent in life!

1.High efficiency MPPT control algorithm, MPPT efficiency ≥99.5%, whole Machine conversion efficiency upto 98%;
2.Charge mode: three stages (fast charge, constant charge, floating charge), improve boost voltage charge(activate the battery performance), it prolongs service life of the batteries;
3.Discharge mode: ON/OFF mode, PV voltage control mode, Dual Time control mode, PV&Time control mode;
4.Customers can choose battery types: (Flooded, Sealed lead acid, Gel battery) charging, Other types of the batteries can also be defined;
5.Most information could be provide by LCD like: System type, PV input voltage, PV input current, Day/Month/Total generated energy, battery type, battery voltage, charging current, charging power, Load current, Load power and so on;
6.RS485 communication, we can offer communication protocol also, it’s convenient for user’s integration management.
7.CE, RoHS, FCC certifications approved. We can help clients to approve other certifications.
8.2 years warranty.And 3~10 years extended warranty service also can be provided.
