Bears OLB Leonard Floyd (concussion) is listed as doubtful for Week 17. As fellow OLB Pernell McPhee (shoulder) was listed as questionable after not practicing all week, the Bears may be without two of their top edge pass rushers against the Vikings.
Solar Controllers. In a solar thermal system, the controller measures the temperature of the solar collector and one or more points in the storage tank and then powers the circulation pump(s) and motorized valve(s).
The PWM charge controller is a good low cost solution for small systems only, when solar cell temperature is moderate to high (between 45Â°C and 75Â°C). MPPT. To fully exploit the potential of the MPPT controller, the array voltage should be substantially higher than the battery voltage.
