There was a post on here of all batties, concerning voltages and usable part of batteryShowing the range to use, based on cell voltage & SOC Tha...

@dtbaker61 Have you ever watched Off Grid Garage on youtube ? He has done lots of testing and graphing and explaining the results of voltage , capaci...

@ouijifour setting 100% at 55.2 will cause problems because you are never getting to the point where the voltage curve is steep enough to be accurate ...

@dtbaker61 My bms is programmed to reset to 100% at 55.2v . I understand what you are saying though that many bms are programmed to reset the SOC at 5...

@ouijifour , you want to use the absorb = 56.2 , not 55.2 .... it is important to get EOC high enough to reset BMS to 100% and balance. firmware o...

@dtbaker61 Tomorrow I am trying lead acid 55.2 v absorb 53.6 float and 54 v for equalize 0 days and 0 time. I will see how that goes.

@ouijifour , if you can get the BMS communicating correctly between battery and inverter, you can use 'lithium' and manage setpoints by % since the ba...

@dtbaker61 I see in your settings that you have Veq higher than your float ? Does this do some trick to the firmware to make it work better in lead ...

yesterday I had closed loop and for some reason it went up and down 5 times from 55.6 to 53.9 v. I decided to go back to Lead Acid settings and it did...

@ouijifour , version= ccaa-190D0E seems to be "fairly good" most of the time. I see a CC/CV charge curve "as programmed" most of the time, but have no...

I wouldn't have gotten the eg4 6000XP had I known it was so wonky with charging lithium batteries. Hopefully a firmware update fixes this.

I think that's effectively what I do when I charge using the Chargeverter. It's set to charge at 56V, and I leave it running until all six batteries e...

Never mind. Signature Solar has now sold out of these remanufactured 18k PV's.
