March 23, 20215 yr Is it possible to change Pylontech US2000C BMS settings? Such as maximum charging / discharging current, recommended charging / discharging current, maximum discharge depth? Thanks for the feedback Edited March 23, 20215 yr by rezna8

There was a post about this somewhere, sorry, I forget where and don't have to time to search for it. Not exactly plug and play, and I think there was some uncertainty about some of the commands. I don't own a Pylontech, but I wish someone who does would sort this out and post the details for all.
March 23, 20215 yr It is possible via BatteryView. You have to logon as an Administrator and bring up the parameter and config tabs.

September 15, 20214 yr Hey @PurePower Could you perhaps PM the Admin password? I'm trying to see if I can find a solution to stop charge current when the batteries are at 99% capacity so that my Growatt inverter doesn't disable PV power when they hit 100% during the day. Many thanks!
September 15, 20214 yr You could do it with an Arduino. You read the data coming from the battery, modify it and then send it on to the inverter. That way you also don't alter the Battery settings.

Many thanks! The issue with the growatt with the 145v mppts is the panels connect to the low voltage dc bus, and therefore the solar gets switched off when the batteries are full to prevent overcharging of the lithium batteries that use comms. If you disconnect the comms and use the custom settings it wont switch of the solar once the batteries are full. It seems the pylontechs for the us3000 limits charge to 37A till 90% then at 14A then at 99% i saw it limits it to 7A. Maybe changing the last one to 0amps might cause the battery to never reach 100% and thus never switch off the solar. Let us know if this is even possible.

I don't know the Growatts, but I'd be surprised if they didn't allow powering loads with PV, so the PV won't get "switched off" when the batteries are full. 18 hours ago, De0n19 said: If you disconnect the comms and use the custom settings it wont switch of the solar once the batteries are full. ? Again, I don't know about Growatts but I'd be very surprised if they didn't taper the charge as the voltage setting is approached.

Attached you will find the solar charging up the batteries to 100% then running of batteries till 94% then charging again
October 16, 20223 yr Sorry to bring back from the dead this topic , but I would also be interested in logging in as admin and changing voltage on one of my batteries. This one battery is always reporting HIGH voltage on one cell when it reaches 97% SOC and would like to try and load all batteries only to 95-96% instead of 100. ID Day Time Volt Curr Tempr Tlow Thigh Vlowest Vhighest Base.St Volt.St Curr.St Temp.St ErrCode MosT.St SOC TotalCoul ID BVolt BTempr BVolt.St BTemp.St 150 22-10-04 14:50:47 52495 6985 40700 28900 29300 3426 3601 Charge Normal Normal Normal 0x0 Normal 97% 74000 1 3601 29300 High Normal 151 22-10-06 16:12:07 52550 5004 36400 27800 28300 3435 3600 Charge Normal Normal Normal 0x0 Normal 98% 74000 1 3600 28200 High Normal 154 22-10-16 18:21:54 52207 6863 35500 28100 28700 3417 3600 Charge Normal Normal Normal 0x0 Normal 97% 74000 1 3600 28600 High Normal I can see it is the last battery to charge in the pack as BMS limiting current due to high voltage.

Hi purepower.. i have the same issue as no charge current and discharge current is present in my battery view screen.. and i have some issues with a growatt sph that cycles up and down in chage and discharge current, i suspect it cant read the setting of max charge and discharge current too.. can i ask for the admin pass too so i can set max allowed ? thasnks
