    • Great MPPT charger, should've bought this first
Size: 40A MPPT Style: Controller
I bought this after initially purchasing a PWM solar charger (cheaper, I was new to solar...) and the difference is substantial. First, I will stick with Renogy products moving forward -- I purchased a CNBOU solar charger (MPPT) for a little less than this but found that it worked terribly and was inconsistent; took a long time to sense the batteries and either didn't charge them or could detect the charge (perpetually @ 45%). After many months of anger and frustration, purchased the Renogy 40A MPPT and have been MUCH happier ever since. I don't have a huge solar array (2 100W panels > 100Ah battery bank @ 24v) but this controller does a much better job of getting as much power from the panels to the batteries as possible, even on over-cast days. If you're just getting into solar, it's tempting to skimp and get less expensive components however it doesn't take long before you out-grow these starter items; might as well plan for the future -- it'll save you $$$ down the road in un-used equipment! ... show more

    • Vastly inferior to Xantrex C35
Size: 40A MPPT Style: Controller
My 9 year old Xantrex C35, 35 Amp charge controller failed just as I was starting an extended vacation on my 50 foot solar powered houseboat (read my article in Houseboat Magazine, The Joys Of Free Power) so I replaced it. But then I realized that maybe I should have bought an MPPT controller, so I tried the Rover. On a sunny day my 500AH bank hits Bulk (14.4V) around 10AM, and by 11PM I have completed the absorption phase and the C35 takes me to 13.5V. This Renogy unit never got me to the full Bulk voltage, and I spent all day cooking my batteries at 14.4 Volts, just below the default Bulk setting for flooded batteries of 14.8V. Then I used the menu option to set it to Sealed batteries but then it cooked my batteries all day at 14.2V, never getting high enough to satisfy the controller that I was in the absorption phase. Speaking of Menus, the menu options never let me get to any other options, and I tried the included USB-RS232 cable and downloaded their software and could not get into the unit with my PC. The Renogy software required a password, which I could never figure out and I never got a reply from Renogy Customer Service despite opening a ticket with them. Either the firmware isn't fully implemented or it's just a really bad design. Never using these guys again. ... show more

Bought this unit to go with my Renogy 100w Solar Suitcase. Renogy's products appear to be quality, although the instructions on their products are a mite skimpy on information. I mounted my controller in a DeWalt case to protect it. See photos- Some things I learned: When installing the mc4 connectors with Renogy's 10awg tray cable, strip the end to install the metal connector but ALSO strip about 3/8" more of only the outer portion of the two part insulation. This will allow you, after you've crimped on the metal connector, to slide the back cap on and then slide the plastic connector (male or female) down far enough so that the two metal pieces will connect properly. Secondly... some complained about the connection at the bottom of the controller. One previous reviewer noted that if you crimp on a spade or male butt connector it makes for a more secure connection. I tried that and it works great... really appreciated the advice. Be sure to slide the spade in toward the top or face side of the hole and then gently snug the securing screw down. If (with the unit facing upwards) the wire or spade slides in towards the back, or lower side of the hole it will be below the securing piece and when you tighten screw it will not hold the wire (loosen the screw and look inside the hole). I believe that those who commented that the wire wouldn't secure in place did not have the wire on the correct side. Don't over tighten. These aren't the lugs on your pickup. I cranked my unit up today and it was working flawlessly! Thanks Renogy for a really solid quality product.... and thanks for your tech support! I will update as I get a few hours on this unit. Update 9/16/17 : Set up at 1:30 pm - clear afternoon started out at 5.9 amps but in a bit leveled out at 5.4-5.6 amps coming from the panel. Voltage leveled out at 13.4 v on the charge side... with17.8 v from the 100w Renogy Solar Suitcase We changed out all the lights in the rv to LED bulbs After having four - two bulb lights on for approx 1.5 hours last night the solar brought my battery back to 100% in about 15 minutes. Must admit that solar is a bit of a new experience... I have to say I'm impressed with this solar setup from Renogy. ... show more
