Customer Reviews
Excellent MPPT controler. By
6 days ago we had a hurricane pass over my home of Barbados with Cat 1 winds.  All power has been disrupted since then, I've been using it with a Bioanno 70amp battery for Amateur Radio plus powering my C-pap machine.  At 80% depletion of the battery, using a 305watt solar panel it's taking about 4.5 hours to complete charging.  I wouldn't have got by with out this set up.  8P6RC

300 Watt MPPT Charge Controller By
I bought two of these.  Bench tested with 40VDC 30A source.  Both showed 14.65  VDC out no load.  Loaded to 15A out, voltage at device's Anderson Connector pins showed 14.64VDC.  Loaded to 20.5A out, voltage showed 14.41VDC (295 watts).  Loaded to 21.5A, voltage showed 13.6VDC (a full volt under OCV).  Don't draw more than 20A or the output voltage falls off fast.  The label on the device says 24 Amps, ignore it.  Ran at 20.5A 14.41V for 30 minutes and output was stable.  Unit heats up and output wires (16AWG) heat (warm to touch) but it performed well.  Scope showed clean DC output.  Keep it within 300 watts and preferably where airflow can cool it.   Mounting it to a metal plate will also draw heat away.  This unit works well and is very reasonably priced.
