    When coupled to a 12V solar panel, this charge controller does all the off-grid battery charging and monitoring required to supply 12V for my 1-to-2-day continuous load using an 18AH AGM 12V battery for day-time recharge. I use this PWM controller coupled to a Renogy 30W monocrystaline solar panel. The controller and it’s LCD battery/load metering works as specified; the built-in (2) USB and (2) 12V receptacles are switched ON/OFF by a single button — very convenient to my remote camera/tablet…
