Renogy Voyager 20A Waterproof Solar Charge Controller | 20 Amp | 12/24V Auto Review

I haven't had this long enough to give a thorough review but I'd like to report that I haven't had any RFI issues so far. After some backyard testing and nearly 48 hours of ARRL field day at 80-15 meters, no radio interference was detected from the charge controller. It's FCC certified on the manufacturer's website, although it doesn't say what it's for. It is most likely Part 15 Class B as listed on some of their other products and is what you should look for in any equipment used with radios.

Bought Jan 6th stopped working on March 7th. Sent to Renogy for evaluation same week. I had to call them to get the results of the evaluation. They said defective and sent another one. It lasted less than a month. sent back. It arrived on May 5th and I haven't heard from them, it is now May 28th. I know things are slow due to the pandemic but that seems a bit of an exaggeration. I want my solar system to work. It would probably be better if they only refunded me for the controller. Email sent…

Connected and tested on Saturday. Connected the solar panel for a few hours. On Tuesday I went to see how much the battery was being drained from having the panel connected to the battery during my days off, only to find the screen was blank. Checked, I had 12.5v on the controller battery screws. This is consistent with other reviews so this seems like a big issue. As for the rear, I'm wondering why there isn't some sort of heatsink on the back (like most solar controllers). Sent Tuesday under…

This definitely seems like a cheap design. This is the second time in a month that the display has stopped and the output has switched to AC. Two points to solve: 1) The main chip that controls the display is burned out or something like that. The display ends and no data is displayed. This happened after 2 days of using the first and 4 weeks of using the second. I really smelled his burnout on the second today. 2) Once the main chip burns out, the output voltage will no longer be controlled…

I bought this for my sailboat and chose this particular model because it will be installed in a place where it can get wet. I connected it to a 24 volt system (2 12 volt deep cycle batteries in series + 2 12 volt solar panels in series. The unit automatically recognized 24 volts and started charging immediately. Close as instructed, attach the batteries first and then the solar panels. The display is easy to read. The only very minor improvement I would suggest is that the unit mounts flush to…

UPDATE: After reading this initial review, Renogy contacted me and sent a replacement. This new block works fine. For this reason I have changed my rating to 4 stars (originally 1 star). Renogy seems to stand behind their product, it just took a little effort. The Renogy Voyager 20A charge controller was very easy to install. I connected it to my 12v deep discharge battery and then to a Renogy 50w solar panel. The display indicated that the battery was charging and I was able to easily view the

I've tried several solar charge controllers and they didn't live up to expectations. I use a 12V electric fence charger with a lead-acid battery (small tractor). My calculations showed that even in average sunlight for my area, my 20W solar panel should keep the battery charged, but I ended up having to bring the battery to charge at least twice a week to keep it charged. then I switch to this charge controller. I used it for 2 weeks with the same solar panel and battery as before and it kept…
