Thanks so much for this video. Most other people on You Tube skipped over this step. I spent about an hour hooking up the monitor and about 3 hours trying to get the answers for this issue. Thank you again!
Thank you! The instruction booklet is very poor! And although Renogy keeps replying to my requests for help, they have provided nothing of value. You solved my problem in just over 4 min! Thank you!🙏
By far the clearest explanation I have found, thank you. The manual that comes with the unit is worse than useless. If you follow the manual, it instructs you to drain the battery bank until it is dead before you can set the capacity. Clearly, that is not necessary.
Sir you are a saint. Thanks for the excellent and clear explination. Your video should be used by Renogy as their destructions supplied with the monitor aren't very good.
Thanks. I could not figure out how to set the capacity after the battery was full. The Renogy instructions clearly say to press and hold the down arrow, I think that is a misprint, thanks to your video I learned to press and hold the up arrow, though even that did not work the first time and I had to do it a second time.
Thank you so much for this video it showed me a lot I appreciate it I'm about to get me a battery monitor for my 400 watt battery system 400 amp power system I should say
@thinklikeacoder I have a question. In the CAP section how do I know how many AH to put in. Is it for example I have 8 batterie that are 100ah each. I would 800AH in the CAP. Is that correct?
Hi There. Thank you for this educational video. I’m a newbie with this kind of stuff. So, if my question is not very smart, please forgive me. I have 2 100ah batteries connected in parallel, in total I have 200ah, 12v, do I need to set up my capacity to 200ah? Also, will this work exact same thing in reverse if I drain the battery completely and set the capacity AH to 0 percent?
I have been unable to set the capacity below the default value of 100 Ah. Does anyone know if this is the way it works? I can set it to 100 Ah or greater, but it will not accept values below 100 Ah. At present, my sailboat house battery is a single, 81 Ah battery (since it currently only supports sailing instruments and lighting).
I ran 2/0, but I tend to overkill. A 9 inch 2/0 from battery to shunt is only about 10 bucks premade, and you don't have to worry about it being undersized.
Hi there I dont know if you can help me out here. I have the same monitor when I connect it to solar to charge the screen keeps on blinking on and off. when it is charged and I disconnect it it is fine the light it of I press the ok button the light turns on for a few seconds then goes off. It measures fine. it is just when I connect my solar it constantly blinks on and off. Cheers Bill
It's doing that to tell you your charging your batt. More powers going in than out. If powers going out. It stays green. If there no power going in or out. The lights off. You can turn off the light. Just hold the Ok for a bit. It will make 3 beeps..
Why did you set the high voltage so high at 15.2? I assumed this would be the 100% state of charge figure for whatever battery you run. I'm having an issue where mine goes from 50 straight to 100% when I start charging. Wonder if the monitor sees the 14v which is above my set high number and instantly thinks its full. Might try bumping it up and doing another draw down and charge test
@@bradleymarshall5591any idea the logic behind doing it this way? I’m having the same charging issue, but what’s the point have having the high voltage setting if you’re putting an arbitrary number in.
I searched and searched for this information, then decided to download the manual from LiTime (formerly AmpereTime), one of the suppliers of 200 Ah/200A BMS 12v LiFePo4 batteries, and found these recommendations for solar controller settings: Usable capacity, 200 Ah; Over Voltage Disconnect, 15v; Under Voltage Warning, 11.6v; Low Voltage Disconnect 10.8v. LiTime recommends 10.8 as the low voltage disconnect, which it correlates to 1% battery capacity. Perhaps the creator of this video is using similar numbers from the manufacturer of his particular battery to come up with 15.2v as the high and 11.2 v as the low. As for where to set the low voltage alarm, I am inclined to set it at 12.9v, which is 20% charge voltage, which gives me plenty of time to start a charge cycle before I'm completely out of juice.
Good m an...I've just installed one of them and I'm in the tropics on a yacht and now I can set it up and then never ever look at the damned thing again. 😎😎
....how? I suppose you could completely discharge the battery, tell the monitor to start, and then have it count til it's full, then tell it to stop. As far as voltages go, yes. It detects the actual voltage, but it doesn't necessarily guess the correct chemistry. Without knowing the chemistry, you can't know the high and low voltage alarm settings.
@@christopherowens2635 this video does that. Check your battery manufacturer for the amp hours, high/overcurrent alarm, and low/undercurrent alarm specs. The last one (amp hour alarm) is personal preference. I have a 300 amp hour chins battery and set the amp alarm at 50.

You're instructions worked perfectly with my Ali brand monitor which as far as I can see is an exact copy of the Renogy version.
Thanks man. I couldn't figure out how to determine what was the high and low. .... awesome
Thanks for going through this step by step.
Sir you are a saint. Thanks for the excellent and clear explination. Your video should be used by Renogy as their destructions supplied with the monitor aren't very good.
Thank you. I' have the Lnex version of this and neither their nor renogy's documentation explained how to do this.

Well explained helped me a lot.
Great presentation
How do you know what to manually set as your bounds for voltage? Thanks!
Thank you, good video!
Well Done!! Thank you.

I am glad to recommend a new battery monitor KG140F to everyone
Do you know how to stop the battery from discharging ,when it reach 11.2. Voltage
Thank you sir! That 3x4 booklet with the monitor was not good enough!
How do you know if your battery capacity is at 100% if you don't already have a battery monitor hooked up?
Use an AC charger that can indicate that your battery is full.
Then you can go from there.
What size wire did you run from the shunt to the neg on battery?
I ran 2/0, but I tend to overkill. A 9 inch 2/0 from battery to shunt is only about 10 bucks premade, and you don't have to worry about it being undersized.

Just got one of these, should I set it to the actual battery capacity which is 100ah or the useable capacity which is approx 75ah?
Set it to the 75ah. You want to match the capacity of your battery with the monitor.
Why did you set the high voltage so high at 15.2? I assumed this would be the 100% state of charge figure for whatever battery you run. I'm having an issue where mine goes from 50 straight to 100% when I start charging. Wonder if the monitor sees the 14v which is above my set high number and instantly thinks its full. Might try bumping it up and doing another draw down and charge test
This worked for me. High voltage needs to be above the charge rate to stop it showing 100% as soon as you start dcdc charging.
@@bradleymarshall5591any idea the logic behind doing it this way? I’m having the same charging issue, but what’s the point have having the high voltage setting if you’re putting an arbitrary number in.
Where did you get the high and low voltages to enter. Thank you
Check the battery manufacturer web site.

Shouldn't it be usable AH not capacity AH?
I’m pretty sure you’re correct, should be entering 160AH (80% usable capacity)
Wait a minute! Shouldn’t this renogy battery monitor automatically detects the voltage and amps of the battery you hooked up to?

@@Canthus13 Interesting… Well, someone might have to walk me through the process of howing the Renogy device define my battery’s information.
