I gave this unit 4 stars due to the missing screws on the pcb (only 1 of 4 had the screws in it), the sever lack of serviceability on the 3 fuses, and capacitors, and the incredibly bad thought they did by potting the capacitors. This is the worse thing I have seen done! If there is a failure, the top can not vent through the safety release, and the walls can not expand. If it gets to rupture pressure, it will explode and destroy the board!! This is not from Renogy, this was done by the manufacture. If you use this correctly and had good batch of capacitors this should not be an issue. PWM does stress capacitors. I was not able to get ratings off of them to see if they oversize them to compensate for this.
Other than those issues.. I do like this unit. The surface area for cooling looks very well. Inspection of the surface mount components looks to be of good quality. I did not find any cracked or still having the beads in the joints. The board has a nice even conformal coating which will make this board have much longer lifespan. The transistors have full electrical isolation from the shell, very nice touch. The mounts on them are isolated as well and have a locking material on the heads to prevent them from backing out.
Another thing I really like was the negative buss bar to all 3 ground terminals. It is very thick and tall. This bar will handle 40 amps with no problem all day long. This also allows me to use any ground point at any time. In the pictures it appears if the wire was to tall it would short positive to negative, this is not the case.. With the case on, it has a built in plastic bar that goes right down to the board to prevent this from happening.
The MPPT is very fast and precise on this unit. Having 2 c.c. power supplies I watched it hunt. It was very fast in finding the max current and voltage. It also kept searching after locked. The search was very small deviations and did not affect its performance. When a 3rd c.c. power source was attached it found the MPPT point and locked quick and kept searching. This units MPPT is the fastest and most accurate I have seen. The small deviations for search after lock appears to be +/- .3V - */-.25A
I did get the head unit for this, so I can not advise on how hard it is to program though the case buttons.
Remember... This is 40 amps max not a 1000 watt max, with 12 volt system it is good for 500 watts, with 24 its 1000 watts. The manual recommends 800 watts max solar though.
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.
