Hi,
I want to use a small victron system as a power station for my home server but my settings don't seem to work. I want to use my grid connected PV system to charge a battery with AC and discharge during the night to keep my home server running on solar power.
Setup:
- PV with sungrow inverter without battery grid connected. SML Meter and AC Loads Smart meter connected to Home Assistant
- Multiplus 48/800, Pylontec 3000c, Raspi + Venus (AC IN connected to Socket, AC out connect to the server)
- Venus OS Dbus Driver: I modified https://github.com/vikt0rm/dbus-shelly-1pm-pvinverter script to forward to sungrow inverter data to venus as a PvInverter and this script https://github.com/fabian-lauer/dbus-shelly-3em-smartmeter to forward the grid data to venus. (works)
- settings according to : https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom
Screenshot discharging:
It should only cover these loads:
350W is the whole house in standby. 133W is the server and network connected to AC-Out.
During the day the PV inverter shows the PV production and the Grid shows the export. However only charging with 6 A not 16A which would be max.
My Goal:
If there is enough power from the PV (sungrow) charge the battery via AC (ideally with dynamic charging current). If there is no excess power feed only AC out with the battery
Problem:
1. When Discharging the battery covers AC in and AC out to balance my whole house.
2. When Charging, it only uses 6A despite having plenty of power available (>1kW).
3. The panel shows AC Loads instead of AC-Out
Thank you for any ideas.
