Hi,
I can’t get why my Pylontech US5000 battery is constantly discharges when grid is available. I’m using default settings without ESS. Also battery and inverter are connected correctly. It’s backup setup - just inverter and battery.
I also noticed several times it works as it should:
@Serhiy
I posted about this myself… Pylontech Charging Interrupted by DC Load - #15 by JohnC
My take on it. What say ye?.
@Serhiy
Can you post the AC-out consumption for that period when it worked correctly?
I have the feeling that it was much bigger than the usual, so the “residual” current that the inverter “leaked” towards battery has compensated the current needed for battery idle functioning…
@JohnC ,
Yes, looks like the same issue but with simplier setup on my side.
@Serhiy
Are you familiar with Cerbo’s SSH access?
If yes, see what I’ve suggested in JohnC topic he linked a couple a post above.
Ok, found it. What should I set in my case? Usually it is drawing 5W or 0.1A from the battery (as on the last screenshot of the 1st message).
Hi @Serhiy
Sorry for late reply.
Set it to 1A.
Anyway, the system will round up to the nearest integer if you set it below 1.
The value it’s not memorized in NV memory and after Cerbo’s restart / power off, you’ll need to modify it again.
Unless you modify in the /opt/victronenergy/dbus-systemcalc-py/delegates/dvcc.py script the initialization for that dbus variable.
Search for: self._dbusservice.add_path(‘/Debug/BatteryOperationalLimits/CurrentOffset’, value=0, writeable=True) and modify the init value with 1.
@alexpescaru
I’d like to enable ESS with allowed batteries charging only during the night time. Do you know if it supposed to work the same way as now during the day time? (don’t discharge battery when grid is available)
You have a quite simple system, with no additional and/or dynamical loads, so I don’t see why not…
Enable it and any doubt will disappear.
