12V/24V 20A MPPT Solar Controller WS-MPPT30

 

Brand:	WELLSEE	Size:	193*110*48mm
products name:	solar controller	Weight:	740g
Model:	WS-MPPT30 20A	Package:	20pc/ctn

WS-MPPT20 20A solar controller(also known as WELLSEE intelligent solar charge controller, solar charge controller, PV controller) can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by 10%~30%. WELLSEE WS-MPPT solar controllers 10 Amp—60 Amp include 12V series, 24V series and 48V series.

 

MPPT advantage:

Maximum Power Point Tracking (MPPT in short) system is a system which allows PV panels to outputs more Power by adjusting working condition of the electrical module. the ordinary controller, which makes PV battery work on 12V ,only outputs  power of 53W (a general power point); MPPT controller makes PV battery always work at the maximum power point, thus outputs  power of 75W (the maximum power point).

Product features:

1. Applicable to various types of batteries,
2. MPPT function
3. Temperature sensor battery charging compensation
4. Overload protection (automatic restoration)
5. Overcharge protection
6. Short circuit protection (automatic restoration) ,
7. Thunder protection
8. Reverse discharge protection
9. Reverse polarity connection protection (automatic restoration)
10. Under voltage protection

MPPT principle:

The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. This WS-MPPT solar controller can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by about 30%.

However, due to many different factors, such as the difference in solar panel making, the change the Sun illuminance, change in temperature, the efficiency of the controller etc., the actually available increased rate is 10%~30%.
