Hi all
I have a question regarding some in my opinion strange charging behavior. Not sure whats wrong.
My setup is 400ah 14s200p batteries ~20kwh
Victron multiplus 2, 48v / 5000va
Victron 250/100 mppt
Cerbo GX
Batrium watchmon core with k9 via canbus to GX unit.
20 panels of 310w / 6.2kwp
Here is a small video, I'll try to explain what I think is weird
System is off grid for now, due to everyone here in EU wanting solar, the approvement time is upwards of 12 weeks now... At least I can charge my car now.
See PV power is around 800w going into the battery in the video. Target in batrium is set to 50a using ramped target. I figured that was quite low power coming in, so I tried with a heat gun turning to max heat, you will see the AC load increasing of course, but also the PV input increasing a lot at the same time, like something is compensating for the extra load. As soon as I turn off the heatgun the PV power goes down, so something in the system is limiting the incoming power? Same thing if I turn off the inverter, so only mppt charging.
I was hoping to see a full charge this weekend but not gonna happen with this going on..
I kinda wanted it to do as batrium says, target set at 50a give more power to the batteries (SOC% might be wrong, have not had the system running for more than a day)
In the charging tab, limited power cell volt im not sure what that is ? and what Im suppose to set it at
(Headphone warning, from heatgun)

I hope some of you guys can point me in the right direction I doubt its mppt setting, but could be wrong
Have a great sunday,
From Rasmus
