Reviews of HQRP 20 Amp 12V / 24V Solar Charge Controller for Solar Energy

Customer Ratings:

I set up a basic solar system for my sailboat on a very limited budget using this charge controller. It is rated for up to 300 Watts of solar panels and I have two DMSolar 145 Watt panels that I also bought from Amazon, and 12 guage cables and parallel connectors from HQRP, the connectors now come free with the panels. For $47 I don't think you can find a better value in a charge controller. The controller is extremely easy to use and understand, and is doing a good job of keeping two 125 AH batteries charged up (usually by lunchtime despite drawing the battery bank down to 12.4 V during the night with usage.) My only complaints are about the panel input receptacles, yes it would be nice to use 10 gauge wire and the screws seem barely adequate but the next step up is to a $160 controller. If you have the money, you can buy a programmable WPM controller from Morningstar (the TS45) which allows you to set the charging voltage at a higher voltage (say 14.8) which does make a difference in the amount of energy stored in the battery and perhaps also in their lifespan. Summary: incredible value in a budget priced charge controller for someone with less than 300 watts of panels.

not happy with this product. i was unable to secure the #10 stranded wire into the slots. when i place them in and tightened the tiny little screw IT DID NOTHING. so the wires fell out. i wrote the supplier and they suggested i turn the unit upside down so the wires just lay in the unit and quote"I may be using too large of wire) unit is rated for #6 (that size would never go in) and the solar panels ask for #10. also it was said by the supplier that the unit was made to not hold wires securely. I think this is bogus. No suggestions were made as to return the item. SO FAR I HAVE NOT DONE THE UPSIDE DOWN THING. THIS IS IN AN RV AND I THINK THE ROAD BUMPS WOULD DISLODGE THEM AND THAT WOULD BE A CONSTANT IRRITANT.
