Q&A
- Can I connect the controller to my 12v/24v solar system?
- Yes, the controller is suitable for both 12v and 24v systems, and it can sense the system voltage automatically once it is correctly connected to a GEL, AGM, or Flooded battery bank. Please set the parameters first before charging your lithium batteries.
- Does it support the Lithium battery?
- this controller supports Gel, AGM, Flooded, and Lithium batteries. Still, please set the correct battery type to use the charge controller with a Lithium battery. Please manually set the system voltage and other parameters to charge your lithium batteries.
- What does IP67 mean?
- IP67 rated indicates that the controller will remain protected and fully operational under various environments, including those where the controller is exposed to water spray, rain, etc., perfectly suitable for outdoor use.
- What is 4-stage charging and how does it benefit the battery?
- 4-stage charging is an intelligent charging capability that allows the controller to monitor the battery status constantly. It will automatically adjust the converter output voltage to eliminate battery over & undercharging problems and fully, efficiently, and safely charge the battery. 1. Bulk charging charges batteries to 75-80% of full charge. 2. Boost Charging gradually completes the remaining charge to full. 3. Float Charging maintains battery charge. 4. Equalization Charging increases the battery voltage to higher than the standard complement voltage and gasifies the battery electrolyte, which is carried out every 28 days. Certain types of batteries benefit from periodic equalizing charges, stirring the electrolyte, balancing battery voltage, and completing chemical reactions.

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.

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!

4 stars explainedPros-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.

I’ve gone through several solar charge controllers that have failed to meet expectations. I’m running a 12V electric fence charger with a lead acid (small tractor) battery. My math showed that even with average sunlight for my area my 20W solar panel should keep the battery charged but I’d end up having to take the battery back to my shop at least twice a week to charge it… then I switch to this charge controller. I’ve had it in service for 2 weeks now with the same solar panel and battery as before and it has kept the battery perfectly charged and once fully charged it floats the battery at 13.8V (exactly right). When the battery discharges at night this controller starts it’s recharge cycle as soon as the sun hits the panel the next morning. It’s Water proof, easy to install and all parameters are plainly visible on the display. I did not install a temperature probe since I’m using a SEL type battery and temperature is usually not as critical as with Li batteries. This works and I do recommend it.Update: I’ve had it in continuous service for a month now and I’ve had a lot of overcast and partly cloudy days but this charge controller has kept the battery charged and the fence fully operational. I have not had to take the battery back to my shop to charge it since I installed this charge controller. It’s very nice to be able to drive up to the corner post and instantly see the solar panel output voltage, actual charge current and battery voltage without opening up the battery box and using a multimeter. Great unit. I’m very happy with it.

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!

I gave it 3 stars only because of the terminals and the lack of output voltage adjust. This makes one wish that manufactures of these products use it themselves. The terminals on the charger made it very difficult to attached the wires that Renogy supplies with their own solar panels. The terminals are small and there is a warning that overtightening will destroy it, which made me uncomfortable about screwing it too tight. This led to the wires popping out constantly. Also, I originally had tinted the wires with a little solder and had to cut off the ends because it wouldn’t fit. Had to jam in the bare wires and the wires constantly frayed. Yuch.My last complaint is just an enhancement. The PWM charger allow lithium battery voltage adjust but the other types of batteries it supports do not. This caused the appliance I was feeding the battery to complain. The output of the charger was about 14.5V and the maximum the appliance supported is 14.2V. Had to disable the warning.

I bought this for my sailboat and chose this specific model because it’s installed in a place were it could get wet. I have it connected to a 24volt system (2 12 volt deep cycle batteries connected in series + 2 12 volt solar panels connected in series. The unit automatically recognized 24 volts and began charging right away. As stated in the instructions, connect batteries first, then the solar panels. The display is easy to read. The only very minor improvement I would suggest is that the unit installs flush against whatever mounting surface it’s on. This is great but there is not enough clearance for the wires behind it, thus necessitating the wires entering in below it then connecting upward. Not a big deal at all, it just means you can see about an inch worth of wires below the unit. I though about building it out with a frame of some sort but decided I can live it with it. Overall, great product at a very good price.

Bought after a cheap no name pwm controller burned up. This unit was well worth the money, as I can see both the charging voltage of the panel and the charge on the battery bank by toggling through the modes on the controller. It even has a place for a temp sensor that when installed helps to keep the batteries from overheating from charging in hot weather. As an added bonus it also shows you how much energy has been produced from the array to the battery, a handy feature to have.Been running the charge controller for over a month and it’s worked flawlessly, and the battery bank has stayed charged. Really regret not buying this one in the beginning, as the cheaper no name ones I first bought actually destroyed one of my batteries before burning up.
