I-Panda High efficient solar controller 12v24v 40A
- Model Number：WISER
- System voltage：DC12V/24V Automatic Recognition
- Rated current：40A
- USB：5V 3A
- Max PV(Voc）input voltage：150VDC (30A,40A,50A)
WISER 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 solar panel. Also added the output function(USB 5V 3A). For the 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.It has an efficient MPPT algorithm, MPPT efficiency ≥99.5%，and converter efficiency up to 98%
2.Charge mode: three stages (constant current, constant voltage, floating charge), it prolongs service life of the batteries.
3.Four types of load mode selection: ON/OFF, PV voltage control, Dual Time control, PV+Time control .
4.Battery system voltage automatic recognition.
5.Three kinds of commonly used lead-acid battery (Seal\Gel\Flooded) parameter settings fcan be selected by the user, and the user can also customize the parameters for other battery charging.
6.Natural cooling design is adopted to improve the reliability of the product and prolong the service life of the product.
7.The input and output of all kinds of protection functions are complete to protect the system.
8.The use of high strength plastic shell design makes the shape beautiful, and the effective reduction of the product weight can save the transportation cost.
9.Equipped with 5V3A USB dual output power supply function, support mobile phone and tablet charging products etc..
10.It has a current limiting charging function. When the power of PV is too large, the controller automatically keeps the charging power, and the charging current will not exceed the rated value.
11.High definition LCD display function to check the device running data and working status, also can support modify the controller display parameter.
12.RS485 communication, we can offer communication protocol to convenient user’s integrated management and secondary development.
13.Support PC software monitoring and WiFi module to realize APP cloud monitoring.
14.CE, RoHS, FCC certifications approved, we can assist clients to pass various certifications.
3 years warranty, and 3~10 years extended warranty service also can be provided
