Hi
I have read the 3 liner explanation on the link below at:
https://www.victronenergy.com/live/ess:design-installation-manual
My questions are as follows:
1) Does this setting have any effect on how a system functions? Reading the above and posts it certainly does. Placing it under Settings -> ESS -> Debug causes some confusion for me. Has this been placed here for convenience while monitoring the values?
2) Does anybody have an example of how the "grid setpoint" should be calculated? i.e. Use System Overview - DC System - DC System (W) on VRM portal to determine the max value and set it to that.
Background on why I am asking the above questions:
I noticed that my battery gets discharged and charged multiple time per day. i.e. < 1% DOD. I am concerned that this is currently causing hundreds of cycles per day and would eventually ruin the batteries. Although the values on the pictures seem small they are more significant at other times during the day.
Charging:
Discharging:
I have set my system to:
System -> DVCC = Enabled (Was not feeding in when not enabled)
System -> Has DC system = Enabled
ESS -> Mode = Keep batteries charged.
ESS -> Feed-in excess solarcharger power = Enabled
ESS -> Debug -> Grid setpoint = 50W
Equipment:
1 X Qauttro 5KVA 48V (FW: 2658433)
1 X SmartSolar 150/70 (FW: v1.37)
1 X BMV 712 (FW: v4.01)
1 X CCGX (FW: v2.23 was doing it on v2.22 as well)
4 X Lead Acid 12V batteries connected in series.
Is the above caused by a feedback delay and sudden change in PV power produced or is something misconfigured? Any help / comments / suggestion would be appreciated.
Kind regards.
Bennie
