SUNRICH 20 Amp 12V/24V DC Input MPPT Solar Charge Controller

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!

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.

This is a very easy to use MPPT solar controller. I use it in my home-made solar crate generator. This solar controller charges my battery almost twice as fast as my old PWM solar controller did. The terminals are very durable. I was able to connect 8 gauge wire to my solar panel connectors making it very durable for something that I move around a lot. The set-up was also very easy and self-explanatory the instruction manual is also easy to follow.

Product charges battery very well. Shows percent battery is charged also. Charges in ‘smart stages’. Product was smart enough to know that i could not charge 2 12 volt (24volts) batteries w 1 solar panel because its not efficient. I can only charge 1 at a time. 2 panels needed for 24 volts.Lots of displays like amps from panel, % battery full, errors. Plz remember to use fuses. Always connect battery then solar panelthe only problem was.... after several months of use, the controller was throwing error 02, battery overcharged. after many hours of thinking it was the solar panel, I finally realized the controller was incorrectly telling me the battery was overcharged when it wasn't. maybe this happened when I hooked up the battery to the controller. solution to fix was easy... just unplug the unit from the battery and replug it in again. followup: unit lasted 4 years and wouldn't work, but for 79.00 and in the heat of louisiana, I guess I can't complain, so I'm buying another.

My set-up is a small solar system for my RV that gets a few weeks of use in the summertime. I liked that after replacing the first faulty unit (within the 30-day return window), the second unit worked for a short time until it also failed. I contacted the company after the second unit failed, and I got the run-around for 4 days. When I finally reach the support guy (which took me two days), I was initially helped and then I was ghosted. I was first told that the problem was a low charge state on my battery (it was reading 13.4 volts at that time and is now 13.6 - controller is still dead). Then, I was asked to send in pictures of a voltmeter battery reading, another of the dead Controller attached to the battery, and another with the Controller after connecting the solar panel where came alive and showed an E15 error code. That was the last of my help from customer support. For two days after submitting the photos, I called repeatedly to get a status and each time was routed to the tech support person's voicemail or told by the person answering the phone that he would get back to me. I was told that he would get back to me "shortly", in a 1/2 hour, before he leaves for the day, etc. I was even told this on a day in which he had left hours earlier. The last time I called, I was told that he would call me back first thing the next morning. No call was received. Slimy people, slimy company. They are not honoring their warranty. I will never do business this company ever again and would caution anyone against dealing with them. Fortunately, when I explained the steps I had taken and that the company was not honoring their warranty, Amazon allowed me to send this device to them even though it was well beyond the 30 return window. I had to eat part of the cost, but I was happy to send it back and never have to deal with this company again. I recommend to anyone that they spend the extra money and get a quality product. Two faulty controllers from Rich Solar and extremely poor customer support; what's not to love.
