WELLSEE brand solar energy photovoltaic generation WS-MPPT15 15A Solar Charge Controller
solar thermal controller
Solar photovoltaic solar power,WS-MPPT15 15A solar controller (also known as WELLSEE intelligent Solar power controller, solar charge controller, PV controller) applies in solar energy photovoltaic systems, which coordinates the working of solar panels, batteries and loads..It 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.
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).
1. Applying with various types of batteries It is mainly suitable for Pb acid and gel batteries.
2. Automatic recognition of input voltage
3. It can distinguish DC12 or DC24V automatically
4. Micro processing controller Pulse Modulation Wide-frequency(PWM)charge.
5. Temperature sensors for charging the battery in compensation
6. Overload protection (automatic comeback)
7. Overcharge protection
8.. Short circuit protection (automatic comeback)
10. Thunder protection
11. Reverse discharge protection
12. Converse polarity connection protection (automatic comeback)
13. undervoltage protection
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%.
