Hi DIY solar forum, Not so knowledgeable asking for over voltage and 3 temperature sensor error resolution. System: 8s lifePo, Daly BMS, Active balancer, MPPT empever charge controller, 1500W/3000W inverter Observations: 1. Soc >99%, 3.3V each cell 2. Inverter on --> beeping --> MPPT reads...

And for the battery - mppt - inverter connections it is connected like this. Any alterations, ensuring fault proof connections you can suggest?

Good morning everyone, This morning the battery’s behaviour showed like this: 9:17h Charge controller comes online: display 0.0V. 9:18h I reset the charge controller: slowly the voltage display goes up to 27.6 9:17h Diff Volt 4.690V! Cell 3 at 0.308V, Cell 4 at 5.0V! 9:19h multimeter...

what are the cell voltages at the end of the day? Today 24.9-25.7V. see screenshots. At 20:00-20:30 the diff volt read 0.7V up to 4.9V! Are the 3.2 to 3.5 the cell Volts? This is typically what the mppt display reads coming online when the first sun hits the What shuts down , the charge...

Thank you for the inputs. Screenshots today of the BMS app. Observations: 11:11h* cloudy morning: 26.7V. 100% SOC *BMS active balance on 19:44h after sunset: charging laptop -1.6A, 24.9V, 97% SOC (19:45 Turn off inverter, no more load) 20:03h: 25.7V, diff volt 0.048V, 96% SOC 20:33h...

Maybe. Though, the BMS 8S should take care of the balancing. My app shows the BMS regularly goes on and off, and balancing is sometimes on, sometimes off. At the moment: Diff vol 0.016v. Though other times it can fluctuate up to 0.6v diff. This helps to identify the cause of dropping voltage...

Right, the BMS 8s lifepo4 I have. Thanks

*No load - no usage - dropping voltage <22V - after sunset CC turns off* Hi experts, On setup below, having no active load (inverter off), minimal usage during the day, after sunset, always within 1-2 hours the charge controller turns off. 24V System 2x 460W panels in series MPPT Epever 60A...
