20A MPPT solar charge controller 12V or 24V battery mode 150V max solar input voltage suit for max 130W or 260W PV 

 

Model specifications

 

 

Model features

1.Double crest or multi crest tracing technique design, when the solar panel is under shadow or part of the solar panel is damaged, multi crest will turns up in I-V curve, the controller can still trace the Max. Power point.

2.Built-in maximum power point tracking algorithm which could promote the energy utilization efficiency of pv system. The charging efficiency is 15%~20% higher than PWM mode.

3.Adopting sorts of tracking algorithm to track the best working point of the I-V curve promptly and accurately, the MPPT efficiency could reach to 99.9%.

4.Adopting advanced digital power supply technology which make the energy conversion efficiency reach up to 97%.

5.Four stage charging mode: MPPT-equalizing charge-boost voltage charge-floating charge.

6.With current-limiting charging mode, when the power of solar panel is oversized and charging current exceeds the rated current, the controller will lower charging power, which enable the system to work under the rated charging current.

7.Have the fault code indication, it helps user confirm the system fault.

8.It can connect with LCD screen monitoring and the controller parameters is amendable.

9.Various load control methods to improve the system's flexibility.

10.With temperature compensation function to adjust the charge and discharge parameters automatically, which could improve the life of the battery.

11.Various system protection function. Including over-charge, over-discharge, over-load, over-heat, the battery reverse connection protection and so on.
