I agree How? battery is input to inverter

bms should stop charging batttery when at set point, not disconnecting dc. In my case there is no disconnection, voltage increase only see video.

I have done a lot of testing so I have tried with three different battery banks and always had the same problem. Having a bad cell in all three banks is not probable. After the failure bank voltage is correct and I have never seen abnormal cell voltage.

An update on this problem. My last modification was using a dump YIT BMS. After 2 months of operation I had 0 inverter failures. Seems Daly for some reason raises voltage over the limit. I am not qualified to say that daly is a crap but at this case it is useless. Maybe there is an equipment...

That was part off experimenting with different values. Regarding equalization, power off happened at least once early in the morning when voltage is usually around 26.2. Does this make sense?

I think it is, duration value is 120, should I set it to 0?

More than a year ago I replaced my gel batteries with lifepo4 24v setup. Inverter is a 4000w Westech. First 5 months were fine but then after upgrading batteries and smart BMSs inverter started power offs. At some point I had many failures and had the chance to identify input over voltage...

I really cannot remember cell voltage. You are right difference increases as voltage goes up, I have seen it when around charged. I will check the voltage behavior after I set up SCC and top balance batteries. Seems I have work to do after holidays!! Thank you for the information and your...

One of the two BMS I use can be configured (Daly) and seems I get valid data. I will probably do a top balancing first chance. Voltage difference is usually at 0.03v max.

Cell voltages are around 3.4+ which does not seem fully charged, right? When inverter is off, voltage rests at around 27,4v now. In the past I have seen higher values I suspect I am missing something. They are quite balanced however. But I think that I have to configure correct my SCC (epever)...

Hello everyone!! I am located in Athens Greece and I have been using solar for 7-8 years. Usage is not for permanent home just about a couple of days every week. I have read a lot of posts on forum so far and what I understand is that there is more to learn. However I still have questions and...
