    Solar Panel Charge Controller
  

*by J***  on Reviewed in the United States 🇺🇸 on December 30, 2010*

When I ordered this controller, I thought that it was essential to prevent the solar panel from draining the battery at night.  What I discovered when the flexible solar panel and this controller were delivered is that the panel output wiring contains a diode to prevent the panel from draining the battery at night.  The documentation says that the real purpose of the controller is to prevent overcharging of the battery.  The only drawback to using both the controller and the diode in the solar panel wiring is the small additional voltage drop of a few tenths of a volt, which should not be a problem, because the open-circuit output voltage of the solar panel is far above (20 volts or more)the approximately 13 volt level of a fully charged battery.

*by T***N on Reviewed in the United States 🇺🇸 on October 10, 2011*

Directions do not state that the unit is powered by the battery side connection before it will allow solar PV current through to charge a battery.  So at first I thought I had a defective unit.  Tech support at MorningStar Corp. was very helpful to clarify how it works.  So make sure that the battery being charged inside a device does not have a resistor in its charging port that will NOT allow backflow of energy or the charge controller will not operate.  It would be handy if the SunGuard unit had a "charging" indicator light on it so you know its actually charging so when the sunlight is too weak you know to reposition the PV panel or pack it up.

Looks like good quality will leave it to charge the battery of my boat year round lets see how it resists...
