RICH SOLAR 20 Amp 12V/24V DC Input MPPT Solar Charge Controller with LCD Display Solar Panel Regulator for Gel Sealed Flooded and Lithium Battery Negative Ground

I have been using my unit for 4 days now. I have an error message (E15) and their manual only lists to E13!! I have tries to call multiple times, I emailed, I tried their live chat, no one is answering and I am left with no power!! This is not the headache, or the product, you want. Trust me!

did the job nicely, only draw back is if you blow the fuse inside it you have to compleatly take it out of your system and dismantle it, then add in a new fuse. other then that its good. terminals are sturdy and can handle the proper guage wire, draw back can only do 20 amp output for all the models. input looks to be flexable

Relatively easy installation. Operates as designed. Keeping my solar battery well charged.

So, I've had several charge controllers, all with plusses and minuses. This one comes closest to perfect. After trying out a Renogy which had issues, I found out this unit is basically a Renogy with better hardware. Even better yet, it uses the same serial protocol and cable wiring as the Renogy. This way, I could use the same monitoring software, which has been working flawlessly ever since. I use it in an all sky camera standalone application (pc, camera, cellular hotspot, battery and solar panels). I did shut it off during the recent cold spell, not because of the controller but the lifepo battery, which shouldn't be charged at low temps. So far, a few months in fairly hard winter weather, and this has held up as well as a victron unit which was my favorite. This one is even better, it has very high conversion efficiency (over 80% on most days) and so far reliable as heck.

1st 1 worked well for 2 years but lost the screen view lcd, & it does not light up which would be huge, (IT'S INSTALLED IN A DARK PLACE AM I RIGHT?) in any case got the replacement & 6 months in no problems. Easy nice large gauge connector slots, full set of parameters for manual settings lovers, a bit confusing on set up, use youtube for the Rich solar controller reviews & set up because the manual is quit poor. Also put a larger fuse in the battery connector wire I have a 30a to cover the bursts of sun energy you get coming out of clouds, this has permanently fixed fuse blow. My set up> 2 PQ 100amp LiFePO, 2 newpowa 100w solar 1 portable Rich 100w hard panel, 11DX,18 ft Alpenlite cab over Camper. GREAT EASY SET UP PLENTY OF POWER. I am full time off grid.
