First off, let me say that I'm no solar wizard. That being said, I can say that this charge controller is vastly superior to the PMW controller it replaced. The charging capacity of the battery is excellent. I have four 140w solar panels powering seven sealed 100ah batteries to power a 1500w GoPower inverter. The system will now run the large freestanding freezer all day while the inverter will indicate a low input after a few hours as before. . I do not discharge batteries below this level. How long the batteries last after sunset depends on the old batteries, not the charge controller, but it usually takes me about 5 hours to get down to 65% and then switch to mains power. I hope this will be helpful to anyone considering this controller. I am very happy with it.
