Control Fronius GEN24 Plus hybrid inverter charging and discharging - Netgalleria/arska-node GitHub Wiki
Arska 1.3 version supports controlling charging and discharging of batteries connected to Fronius GEN24 Plus hybrid inverters
Channel type Fronius GEN24 Plus charging
To control your inverter from Arska, define a channel of type "Fronius GEN24 Plus charging (int)" with IP address of your inverter. Enable Modbus ( int&SF mode) TCP in your inverter.
Using (dis)charging profiles in a rule set
In the baseline Arska version you define target states (up/down) for rules and additional default state which is applied if none of the rule conditions is matching, see more. For inverter channels you define target control profiles which are applied respectively . In the ruleset of inverter channels control profiles are used:
| profile | note |
|---|---|
| Charge 100%/75%/50%/25% | Charge at respective power |
| Charge 0% | Charging and discharging is blocked |
| Discharge 100%/75%/50%/25% | Discharge at respective power |
| No control | Charging is controlled by the inverter, not by Arska |
Testing and manually controlling control profiles
At the dashboard you can manually schedule charging profiles.
Battery charging level SoC
State of Charging (SoC) is queried from the inverter once per 5 minutes. SoC percentage is updated to variable 600 which can be used channel rules.
In addition SoC level is visible in the dashboard graphics.
