Hi there!
Our Victron system is continuously jumping between inverting and bulk and I'm not sure why this is the case. This happens fairy predictably every 30 or so odd seconds and the GX screen also seems to indicate that the grid is online/offline, while this is definitely not the case. The system was still running fine yesterday, and seems to have started jumping between inverting and bulk somewhere during the evening.
The system is comprised of the following components:
- Gateway - Color Control GX
- VE.Bus - 3x Quattro 48/15000/200-2x100 (Freedomwon 40/28)
- Battery monitor - Generic Can-bus BMS battery
- Solar charger - SmartSolar Charger MPPT 250/100 rev2
- Solar charger - SmartSolar Charger MPPT 250/100 rev2
My electricity provider has also already been at the premises to validate that the line voltage is correct and the power quality is supposedly good.
I can also hear relays switching each time it jumps between bulk and inverting. Is such frequent switching detrimental to the expected life time of the system, or would it be ok to leave the system running as is?
Some of the VRM measurements are as follows. The battery was around 36% during.
