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).
A charge controller, or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most 12 volt panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.
