I have a site that discharges battery on keep battery charged? does anyone know why?
Please note this is a backup system. Battery is on 99,9%
Attachments: Up to 8 attachments (including images) can be used with a maximum of 190.8 MiB each and 286.6 MiB total.
How new is the site and what battery are you using?
This may well be due to the BMS balancing the battery, entering charge/discharge cycles.
That will be the bms doing that as part of its balancing. Send a snapshot of the cvl/ccl etc charts from vrm.
Min/max cell voltages.
Battery voltage, soc charts also.
Thanks, you pointed me to the right direction, BMS trying to balance
