Redback Inverter Modes
Below is a table of the full list of possible modes that the inverter can be set to using the Redback 'Schedule' capability via the API.
Most people will be familiar with the first 6 (Auto, Charge Battery, Discharge Battery, Import Power, Export Power) from using the Redback Portal where only those options have been made available. Those 6 are fairly easy to understand what they do and what impact they have on power flowing through your system and to/from the grid. If you are using the Scheduling capability that has been enabled in the Home Assistant Redback Integration the additional modes are available to use.
The rest which may not be as familiar to you, may need a little time to read, reread again before they start to make sense and what they accomplish, particularly when looking to curtail your export power during negative fit pricing.
They are more advanced modes of operating your Redback inverter and some will require having a Redback battery attached to your system for them to work.
| Mode | Description |
|---|---|
| Auto | PBattery = PInv - Pmeter – Ppv (Discharge/Charge) |
| The battery power is controlled by the meter power when the meter communication is normal. | |
| Charge Battery | PBattery = Xset (Charge) |
| Xset is the charging power of the battery. PV power is preferred. When PV power is insufficient, it will buy power from the power grid. The charging power is also affected by the charging current limit. | |
| Discharge Battery | PBattery = Xset (Discharge) |
| Xset is the discharge power of the battery, and the battery discharge has priority. If the PV power is too large, MPPT will be limited. Discharge power is also affected by discharge current limit. | |
| Import Power | PBattery = Xset + PV (Charge) |
| Xset refers to the power purchased from the power grid. The power purchased from the grid is preferred. If the PV power is too large, the MPPT power will be limited.(grid side load is not considered) | |
| Export Power | PBattery = Xset (Discharge) |
| Xset is to sell power to the grid. PV power is preferred. When PV energy is insufficient, the battery will discharge.PV power will be limited by x.(grid side load is not considered) | |
| Conserve | PBattery = PV (Charge) |
| In on‐grid mode, the battery is continuously charged, and only PV power (AC Couple model takes 10% of the rated power of the power grid) is used. The battery can only discharge in off‐grid mode. | |
| Force Charge Battery | PBattery =Xmax + PV (Charge) |
| Xmax is to allow the power to be taken from the grid, and PV power is preferred. When set to 0, only PV power is used. Charging power will be limited by charging current limit. | |
| Force Discharge Battery | PBattery = Xmax(Discharge) |
| Xmax is the allowable discharge power of the battery. When the power fed into the grid is limited, PV power will be used first. | |
| Buy Power | PBattery = PInv – (Pmeter + Xset)– Ppv (Charge/Discharge) |
| When the meter communication is normal, the power purchased from the power grid is controlled as Xset. When the PV power is too large, the MPPT power will be limited. When the load is too large, the battery will discharge. | |
| Sell Power | PBattery = PInv – (Pmeter – Xset) – Ppv (Charge/Discharge) |
| When the communication of electricity meter is normal, the power sold to the power grid is controlled as Xset, PV power is preferred, and the battery discharges when PV energy is insufficient. PV power will be limited by Xset. | |
| Off Grid | PBattery = Pbackup – Ppv (Charge/Discharge) |
| Forced off-grid operation. | |
| Hibernate | PBattery =0 (Standby) |
| The battery does not charge and discharge. | |
| No Mode |
