Dear all,
I'm using ESS on a Multiplus 2. I've gone already to related posts in:
https://community.victronenergy.com/questions/11225/dvcc-and-pylontech-battery.html
https://community.victronenergy.com/questions/16064/battery-monitor512-alarm-high-voltage-alarms-victr.html
and I've configured the system according to: https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom
My Problem:
When I operate ESS in "keep batteries charged" mode, I get "High DC ripple" Alarms and "High Voltage" Alarms leading to shut down the Multiplus at high solar yields (as already described in other posts), even though I've set the "Max Charge Voltage" in DVCC to 51,7 or even less.
Observing the local terminal, I can see charging current although the battery voltage is above 51,7.
When I operate ESS in "Optimized with Battery life" mode, I don’t get Alarms nor shut downs. At the local terminal I can see even discharge currents in case the battery voltage exceeded the limit set in DVCC (after changing from "keep batteries charged" to "Optimized with Battery life" mode).
From what I've seen it appears to me DVCC limits are being not obeyed when operating ESS in "keep batteries charged" mode?
Anyone having similar problems respectively is there any solution to stable- and reliably run ESS in "keep batteries charged" mode ?
