collection of python scripts handling goodwe inverter

as I'm using in my installation. Please note, my setup is 3 solar fields connected to 2 inverters an each having a battery pack aside. Inverters are Goodwe ET6.5 and batteries are axitec 13.5kWh each.

axitec_hold.py

• axitec_hold.py links on
• allows to set an inverter to hold
• if set to hold the charging power is reduced to 100W
• it is set to hold if SoC is above 40%
• if hold is canceled, bms ist set to selfuse and 6000W
• • axitec_hold.py links off

charge_battery.py

• charge_battery.py 75
• charges both inverters to target-SoC
• use this if dynamic prices are low in winter

charge_bms_on_off.py

• uses bms to charge battery from grid
• use this if i'm charging the car while dynamic price is low but don't want to drain the battery
• • charge_bms_on_off.py "on" 50
  • keeps the battery in charging mode, discharging is not allowed
• charge_bms_on_off.py "on" 6500
• • charges battery with high priority from grid

single_modbus_goodwe2influx.py

• fetches all values from a goodwe inverter
• writes measurements in a influxdb
• works with dashboards delivered in json GoodWe_Axited_xx

goodwe_registerliste.txt

• some notes to registers used in my environment
