Detailed Description
Brand:wellsee Category:MPPT solar controller Model:WS-MPPT30 Weight:740g Size:193×110×48 mm We are the super-scale research and development enterprise for solar charge and discharge controller, the supplier of WELLSEE solar controller, photovoltaic system equipment. WELLSEE have passed the ISO9001, CE and RoHS certifications. We can design and produce according to clients’ special request. Welcome to be our agents! MPPT30 30A is short for Maximum Power Point Tracking. MPPT system allows PV panels to outputs the most power by adjusting working condition of the electrical module. WELLSEE WS-MPPT solar controllers (also known as WELLSEE intelligent solar charge controller, solar charge controller, PV controller) 10A--60A include 12V series, 24V series and 48V series. 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%. MPPT advantage: An ordinary controller, which makes PV battery work on 12V ,only outputs power of 53W (a general power point); The MPPT controller makes PV battery always work at the maximum power point, thus outputs power of 75W (the maximum power point). Product features: Applicable to various types of batteries, MPPT function Microprocessor controller pulse width modulation (PWM) charging Temperature sensor the battery charging compensation Overload protection (automatic restoration) Overcharge protection Short circuit protection (automatic restoration) , Thunder protection Reverse discharge protection Reverse polarity connection protection (automatic restoration) Under voltage protection TECHNICAL INDEX: Model WS-MPPT10 WS-MPPT20 WS-MPPT30 Rated Voltage 12V / 24V / 48V Max Load current 10A 20A 30A Input voltage range 12V~40V / 24V~80V / 48V~110V Length≤1m Charge loop drop <0.25V Length≤1m Discharge loop drop <0.15V Over voltage protection 17V / 34V / 68V Full charge cut 13.7V / 27.4V / 54.8V Low voltage cut 10.5V~11V / 21V~22V / 42V~43V Temperature compensation -3mv/℃/cell No load loss ≤10mA Max wire area 2.5 mm2 4 mm2 6 mm2 Ambient temperature -25℃——+55℃
