Batteries more than 8 months together. Yes wiring etc all done correct

Anybody here that have the latest firmware for the 3.5 Pylontechs. Bought a second battery about a year after the first one. After doing all the equalizing etc I can still see on ICC the one working harder than the other. I tried to contact the importer but they have not even replied to my mail. I was also promised the latest firmware from another person, but still did not receive anything. Thanks

Hallo Pieter, soos jy kan sien is ek nie die slim persoon wat jou daai antwoord kan gee nie. Ek weet net dat jy nie die Pi met ICC hoef te gebruik nie maar tenminste moet jy 'n kommunikasie kabel tussen battery en Inverter insit. Wens die slim manne wil my nou ook kom vertel hoekom my een battery harder werk as die ander.

So I got my second Pylontech 3.5 battery connected. Wonderful, enough capacity now to get us through the night until the sun starts to shine again. But I noticed on the ICC that battery nr2 seems to work harder than battery 1. Battery 1 is the master as it is the new one. When I tried to make the old one the master it did not work....got a red light on the battery. I also tried to EQUALIZE the two batteries by only connecting them together and let them settle until the lights went out on both. When both batteries reaches 100% the voltages are the same. Then we start using power, battery nr 2 is always the one with the higher amp discharge. Therefore in the morning after running through the night battery nr1 would be say on 75% SOC and battery nr2 would sit on 45% SOC according to ICC ICC will indicate these two SOC readings under the Pylontech tab, but on the dashboard the 2 would show an average of about 60% Is this correct? any settings somewhere that I missed ?

I was looking at my ICC software and noticed that I have not seen a software update in a while. When bought it from ICC I dealt with a Johan chap. Currently I have 2.8.5. When I looked at the ICC website I see there is some new software but my ICC tells me I am running the LATEST version. Then I emailed ICC asking why my system does not update automatically anymore. This is the response got back : As jy op ICC website gekoop het en n order nommer het van ICC dan sal jy die vooreg he om te update Now how the hell do I have a system that is still working and now suddenly refuses to update if I did not buy it from ICC. The last mail received from ICC after I told this unhelpful person that I previously dealt with a Johan was this : Yes dit lyk of jy by hom gekoop het. Hy sal jou dan moet help Now how does this work. I bought from ICC. Dealt with a Johan. Now I get this SNOTTY answers from ICC. What is going on ? I even bought a Pylontech cable from "ICC" at the same time. I have a working ICC system, I paid my money to ICC. Now suddenly MY ICC is a different ICC. CONFUSED

Thank you Coulomb. Changing that little setting to be 2 Volt below the other FIXED my problem. System is running again like it should. Pity that these "SETTINGS" are not documented openly by the suppliers. I run it on Solar and Grid because I only have one battery currently and we are still in our rainy season. Once I have my second battery installed by November I will change this back to solar only. Thanks again.

Remember I did the Kettle upgrade but killed an EXPERT as our South African Experts cannot take your firmware. It is looking OK for now. It was running OK for nearly a year when I went and adjusted some settings and got LOST... Old age is a bitch and scratching where you should not is a NO-NO.

I now see the extra load that shot up to 4 kw. on this one, but the 10h00 did not go more than 2 kw. Will monitor now that I change that 47.5 to 46 volts

Zoom into the area.

Nope did not fix it. Put kettle on. Looked promising and then suddenly switched over to grid

Thank's. So I will change the 47.5 to 46 V right now.

Nothing big..normal 1.5 to 2 kw. Look at last night graph...and this morning making coffee at 07h00. Again around 10h24. Load about 2 kw.

I was scratching where I should not have and now I have the following issue. I think I have the settings back to where they were, but not sure. My battery is FULL. there is sun but as soon as the load picks up the inverter switches to grid. Axpert 5kw inverter. 1 x 3.5kW Pylontech battery. 9x 335 Watt panels Settings as per picture.

What sort of interface ?

so would your E2301 not work ? I see output could be 110 Volt DC E230I (800W) AVAILABLE IN 12, 24, 48, 110 AND 200 VDC
