Our Solar Charge Controller MPPT 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 standard solar controller, this MPPT controller can increase the efficiency of PV modules by 10%-30%. Solar Charge Controller MPPT 10A–60A include 12V series, 24V series and 48V series.
MPPT advantage:
Maximum Power Point Tracking (MPPT in short) system allows PV panels to output more Power by adjusting working condition of the electrical module. In Figure1 A indicates that the working state of ordinary controller, that is PV battery working on 12V ,only outputting a power point of 53W (the general power point), B indicates that MPPT controllermakes PV battery always work at the maximum power point, thus outputting the power point of 75W (the maximum power point).
Product features:
Applicable to various types of batteries,
MPPT function
Temperature sensor battery charging compensation
Overload protection (automatic restoration)
Overcharge protection
Short circuit protection (automatic restoration) ,
The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. With the intensity of sunshine being constant, the maximum output power decreases with the rise of the temperature. The temperature being constant, when the sunshine intensifies, the open circuit voltage of PV battery basically keeps unchanged. But the short circuit current increases substantially, thus the maximum output power increases substantially.
This WS-MPPT solar panel controllercan 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 controllercan 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 of the sun illuminance, change of temperature, the efficiency of the controlleretc., the actually available increased rate is 10%-30%.
I have purchased 2 20w 24v solar panels, and I wish to link them to my Recreational Vehicle. There preliminary job will be to keep the battery charged, but later on to charge a set of batteries to run the electrical devices (primarily the interior lights).
currently, I’ve just purchased the 2 solar panels. I figure that the charge controller need to be next. Should I just buy a cheap charge controller and lose some of the effectiveness of the solar panels (i’m thinking i’ll lose some charge when the panels drop to match the battery voltage)… or should I pick the more costly MPPT charge controller.
Another note … what gadget should I use to have the solar panels immediately change over to charge the 2nd set of batteries once the begun batter is completely charged?
