Hello,
Devices:
1x Victron Quattro 15000VA
2x Smartsolar 450V 100A
4x Weco 5K3 Battery
1x Cerbo
When the battery is full and there is more than enough solar power to supply loads, instead of leave the battery in idle state until is required, the system use the battery for the loads and continuously discharge and charge again the batt moving it between 98% and 100%. "Battery Life" is NOT enabled.
Any idea? Thanks.
What are you absorption/float voltage settings. Are they maybe quite right?
In my experience the battery is held at float/absorption voltage and MPPT covers the rest of the load when battery is at 100%.
Hello, it's a lithium batt with ve.can bms, so those parameters should be ignored. Anyway, they are this:
What is your battery voltage when this behaviour is happening?
My guess was it was something to do with absorption/float voltages and that the battery voltage was higher than MPPT setting voltages and therefore MPPT wasn't outputing until battery voltage was back below it's threshold. I'm not familiar with BMS controlling those settings so I'm unsure sorry.
However that would be where I'd start checking first. ie the voltage of battery when this is behaviour is occurring and then BMS settings to see if there's a missmatch somewhere causing the behaviour.
