Significant battery voltage reading error with temp sensor attached.

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.

A good simple controller

Bought a 20A version for a small DIY solar for a shed. It is 100% waterproof, completely sealed off, a nice feature to have. The instruction manual is not the best but the device is very easy to install, just connect the wires (the battery first) and it will start working, no on/off switch. You need to select your battery type and the charging voltage. The display is quite primitive but it does the job. While working, it cycles through the input and output data. It starts to show error codes if the input current or battery charge are too low. Would be better if they had something more informative. It offers a temperature sensor as an option, but mine already came with it. It is helpful for optimal charging, but note that the sensor won't do anything if lithium is selected, it must have it's own BMS. In other words, you don't need this sensor if you have a lithium battery. If anything to complain about is that it is supposed to be installed on a wall, but there's no access to wires when it is attached to the wall, so if later you need to re-connect something you'll have to take the device off the wall for that. Overall, seems to be a good cost/benefit choice for a small system, let's see if it lasts. Mine is about 9 month old now and it had no issues, survived the NY winter.

Appears to do the job

I only say it that way since it's only be in service for about a month. 4 star only for poor manual - plenty on the web as a workaround, but that's not so helpful when setting up off grid away from cell towers. Weatherproof got tested recently when we got hit with a combo of hail and 2" of rain. Laying in the bed of my truck it weathered it just fine, unlike a similar unit from another manufacturer. Minor gripes: Would have liked to have a better manual on the settings. Would have liked to have a way to stop the auto-roll of the readings. Showing 25 degC when there is no temperature probe attached is deceiving [probe is available, I just didn't bother to buy the extra component]. There is no load connection - meaning you have to take your power directly from the battery, and this unit will not protect from over-discharge, as do some others. Where this becomes an issue is if your battery is dead. Since it won't charge a battery without a minimum voltage present (seems to be around 9.5V for a 12V settings) there is no way to recover if you do manage to over-discharge your battery. This is more of a warning as it seems to be true of most of these lower-end charge controllers.

This one actually works as advertised

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.
