System details :
- Victron MultiPlus 2
- DC MPTT coupled
- BYD battery
- Grid-tied
- Grid feedback NOT allowed
- DVCC enabled
I am using Scheduled Charging to prevent battery discharge during certain times of the day. "Stop on SOC" set to 50%.
As I understand the documentation, battery discharge is not allowed while the schedule is active.
And this is mostly true - I do not see "large" discharges from the batery.
However, I do observe a continuous, fluctuating "trickle" discharge while charge schedule is active. I easily lose 5% SOC to this in a +-6 hour period.
In the attached screenshot you can observe a 10W draw, while Scheduled Charging is active.
I do NOT see this when min SOC has been reached - then battery draw is zero, as expected.
So my question is, is this:
- a software bug? (venus, mp2, byd BMS)
- misconfiguration?
- harware issue of some sort?
- documentation omission?
Anybody else experiencing same? Not?
