  • Works great. Easy to hook up. Waterproof.
Size: 20 Amp
Handles two 100 watt solar panels and has no problem charging the group 27 battery on my little cargo camper. Its waterproof, so the entire system can be mounted externally. Very easy to install.

  • Working great
Size: 20 Amp
I like Renogy products, good value. I couldn't find a wind generator controller, so bought this solar controller. It's big enough for the amps output of my WG. All is working.

  • Significant battery voltage reading error with temp sensor attached.
Size: 20 Amp
4 stars explained Pros -charging algorithm voltage values are correct as measured with DVM (only flooded, agm and LiFePo4 tested) -LiFePO4 charge voltages can be set by user from 14.2 default to most common values depending on battery manufacturer spec. I use 14.6 volts (new). 2018 version default was 14.4 volts -Completely sealed against elements -When equipped with Temp sensor, will include battery temp on the display rotation (new). Previous version required manually toggling the display -shows input Panel voltage (new). Cons -Battery voltage readings can be inaccurate for all battery types and worsen with temp sensor attached (but solar panel voltage readings OK). -Exchange to get a controller that read accurately resulted in an improvement, but attaching temp sensor again introduced .2v to .4v error. -Battery type selected does not display by default (previous versions did, i.e. Gel, Wet, LiFePo4, AGM) Have to push buttons on new version to go into Select Batt Type menu. -Battery type selection button often unresponsive. -Selecting LiFePo4 charge voltage values sometimes not responsive; if desired value is passed up in scrolling, could not scroll back; had to scroll through full range and couldn't get a response for each push of the button. -Panel and battery connection LEDs no longer present. Loss of an EZ visual status observation, possibly an energy saver. Must wait for status to scroll automatically or must scroll manually through display to see status. --Auto scroll interval too long to see 5 parameters. Two secs per parameter should do it. -Hard reset process discussed with Renogy to clear possible errors not described in manual and might or might not work. (later determined attaching temp sensor caused the incorrect readings) In a nutshell, some of the improvements in this version are welcome and some of the old features are missed. But that isn't the problem. This newer version had inexplicable battery voltage reading errors not present in in 2018 versions I own. Amazon and Renogy were great in trying to get a working replacement, but in the end, decided to abandon that effort in favor of a refund for now. LiFePo4 does not use temp compensated charging as lead acid batteries do. So, when the LiFePO4 battery voltage read spot on, backtracked to see what was different. The difference turned out to be the temperature sensor. I used the sensor for flooded and AGM, but disconnected it for LiFePo4. Attaching it caused a substantial voltage reading error for all battery types that made it impossible to accurately determine battery state of charge. Charge algorithms didn't seem to be affected when measured with an external DVM. Neither of the 2018 versions I own are affected by attaching the temp sensor. One other thing to remember about LiFePo4 batteries is they do not like to "float" at much above 13.6 volts after reaching full charge. This isn't much of a concern in solar charging because charging ceases in the absence of solar energy. Thus there is no real need to have a voltage limited float stage setting after the battery is fully charged and balanced. This is the very first time I've given 4 stars to an item I've been dissatisfied with, but this controller, even with the battery voltage reading issue still offers useful functionality once set up. Use an external monitor if you want accurate voltage readings to monitor state of charge when using with the temperature sensor. Otherwise, I especially like the user defined charging voltages for LiFePO4 as values can vary among LiFePO4 manufacturers. It's important to use the right setting. The temperature sensor addition should only cause the controller to do its job of reducing charging voltages above 77 deg F and increasing charging voltages below 77 deg F where temp compensated charging is necessary. It should NOT affect the accuracy of reading battery voltage. An otherwise 5 star controller gets a "pushed" 4 stars. It does all things well except show acceptable values for temperature compensated flooded and AGM battery voltage. Both the original and the replacement returned to Amazon citing the Renogy case number. If the accuracy of the resting voltage is of utmost importance, then 3 stars. ... show more

It’s simple to wire into a system. I use it to maintain my truck battery as it sits a lot. It’s been good for months now and I have piece of mind my truck will start after week is sitting, even after a cold spell, sub zero temps.

  • New Version: Ground Changes from Negative to Positive
Size: 20 Amp
Had to get this due to an RMA for their 200W Eclipse product that is no longer available. That one had the older Voyager controller with a negative ground and worked with my system configuration. This new one changed to a positive ground and doesn't work in my system. Pictures on Amazon and even Renogy's web site are inconsistent so I wouldn't trust them. The "manuals" also don't mention certain key things. Another thing I noticed that I wound up wasting time troubleshooting was that I had to have the battery and the solar panel connected to get any output. The older version had output once the battery was connected. Was going to drop supporting them and move to a Victron controller but was also a positive ground and wound up ordering an Adventurer. I'm giving up the "waterproof" spec although I never got a chance to test it out with the previous panel. About four uses over a 10 month period and it failed. Support is overall awful and you'll be luckier trying to get someone over a phone call with their limited hours. Still waiting on my refund for the prior combo; it's been almost 2 weeks. Almost 3 weeks later and still no refund. Contacted and could be another couple weeks! Another couple of weeks and now about 5 weeks with no record of any new action on refund. I'm on hold and sure I'll be told another 2 weeks. Too late to return everything renogy for a refund since I'm passed to purchased date now. It's a crap shoot. If your product works then great, but if you need support or customer support. Good luck! ... show more

  • Saved my boondock setup!
Size: 20 Amp
I have a battery array in my off-grid cabin to run lights and water pump. My previous controller could never manage the 190 watt solar panel to correctly keep the array charged, and it only kept the array at 11.5 V. I was thinking I may have had a shorted cell or bad battery. With this controller, I now have a full charge on my batteries and power management is totally hands off. Display tells me how many Kw I have available at any time, and power management from either battery or directly from solar panel is automatic. Bonus is that the unit is outdoors so weatherproofing is a bonus! ... show more
