Hi,
i recognized there's sometimes a gap of pv power when my mppt 100/50 (actual firmware) change from absorption to float. I remeber some firmware versions ago this was a problem and there was a fix in a newer one. Sometimes the complete system load comes from battery while this happens. I don´t know the duration of the gap or if it happens everyday because i write the solar data only every 30s into my database.
How can i contact the support of victron to report this issue?
Thanks.
Hi.
that gap is most likely a normal behavior.
When the MPPT switches from Abs to Float it maintains a new lower target Voltage. The MPPT has to wait for the battery to lower its Voltage to the new target V to continue operation. This can take some time. During that time loads are powered from the battery.

Yes, this is physics in action. If you keep pouring water into the glass then the level will not drop down.
In order for the battery Voltage to reduce from Absorb to Float, PV production must reduce or stop to let the battery Voltage come down. If the PV continues to produce power then the battery Voltage could not come down.
The length of time that it stops producing depends upon how quickly the battery reaches the Float level, if there is a bigger load on the battery it will get to Float quicker.
Hi!
thanks for explaining. That sounds understandable to me.
