I have had problems with my system installed on my camper. As a test I have removed batteries and controller and brought them home. I currently have only the controller and batteries connected together. I have 5 batteries that are all fully charged. They are mixed which I know is wrong so I have tried a couple things.
I have checked settings in all different configurations and nothing changes. 3 of the batteries are alike and the other 2 are alike. If I hook all 5 together or test either set, I get a reading of 32 Amp Hours. The 3 batteries are 105 AH, and the other 2 are 75 AH.

What do you mean by nothing changes?? What are you trying to do?? Are you testing for ah? How are you going about that?? |

The 3 batteries are 105 AH, and the other 2 are 75 AH. If you trying to figure ah you have 465 total ah........... That is if the batteries are all 12v and your system is 12v......... |

I actually started testing to make sure that the batteries were good. My fear was that maybe one in the group was bad. All take and hold a charge. All batteries are flooded and 12 v. What I mean by nothing changes is that, no matter what I hook up, my controller says 32 amp hours. The temperature is near freezing, so I no that will have an impact.
If I hook up 1 battery (12v, 105AH), the controller reads 12.8 v, 100% charge , and 32 AH. If I hook up 3 of the same batteries in parrallel, I get the same readouts.

You need to read the manual and determine what reading you are looking at, battery capacity (input), usage, charge ?

I did read the manual, and Amp Hours are Amp Hours.It;s really not rocket science. My question is, again, why would the controller say that I am getting 32 AH out of one 105AM battery, or a 465AM bank of batteries

Does the controller need an input and load to calculate Amp Hours, or can it stand alone as a meter?

the only Ah I see on the rover 40 are Accumulated AH & Discharged AH
with the BT app I believe you can input battery capacity.
what Ah reading are your referring to?
The controller certainly does not know what size battery bank you have.

Yep that's exactly why I keep asking for him to post a pic of what he is talking about.......

I believe he can use his words to describe better!!! we all know a ah = ah but if he believes the controller knows something, he be wrong.

^^^^^ Yep I agree^^^^^^ The reason I ask is with a pic we can tell him that's what's going out not what he has in reserve...... That's all.........

Specifically which screens says 32Ah? Charge or discharged? If you have other sources charging the battery bank that might also sku the actual charging Ah versus capacity. -Renogy Team |
