WS-MPPT15 12V/24V/48V lamp controller

WS-MPPT15 solar controller lamp controller This WS-MPPT15 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 10A--60A 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. In Figure1 A indicates that the ordinary controller, which makes PV battery work on 12V ,only outputs a power point of 53W (a general power point), B indicates that MPPT controller makes PV battery always work at the maximum power point, thus outputs the power point of 75W (the maximum power point).Product features:Applicable to various types of batteries,MPPT functionMicroprocessor controller pulse width modulation (PWM) chargingTemperature sensor battery charging compensationOverload protection (automatic restoration)Overcharge protectionShort circuit protection (automatic restoration) ,Thunder protectionReverse discharge protectionReverse polarity connection protection (automatic restoration)Under voltage protectionMPPT principle:The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. 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 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%.ModelWS-MPPT10WS-MPPT15Rated Voltage12V / 24V / 48VMax Load current10A15AInput voltage range12V 40V / 24V 80V / 48V 110VLength≤1mCharge loop drop0.25VLength≤1mDischarge loop drop0.05VOver voltage protection17V / 34V / 68VFull charge cut13.7V / 27.4V / 54.8VLow voltage cut10.5V 11V /21V 22V /42V 43VTemperature compensation-3mv/°C /cellNo load loss≤10mAMax wire area2.5 mm22.5mm2Ambient temperature--25°C----+55°CWe are special large scale R&D and manufactory enterprise of solar charge and discharge controller and global supplier of Wellsee solar controller and photovoltaic system equipment.
