Power Station Parameter Setup
Change the plant name
- Tap the name of the power station to set up on the “Home” screen.
- Click behind the station name, and tap “System Settings” → “System Name” to change the name.
Export Limitation parameters setup
Tips
- At the beginning, the installer sets the export limitation parameters based on user’s requirements.
- If you need to change the parameters later, please manually set the up the export limitation parameters following the local laws and regulations and power grid agreements.
- Tap the name of the power station to set up on the “Home” screen.
- Click behind the station name, and tap “System Settings” — “Export Limitation” to setup the parameters.
Set the energy storage operating mode
Tips
The energy storage system has three operating modes, namely, “Al Mode”, “Self-consumption mode”, “Fully Fed to Grid”. The “Al Mode” is recommended.
- Tap the name of the power station to set up on the “Home” screen.
- Click behind the station name, and tap “System Settings” to change the operating mode.
Al Mode
By recording the peaks and troughs of users’ consumption habits and local electricity prices for one week, Al mode can customize smart electricity solutions to maximise savings for customers.
Self-consumption mode
The excess photovoltaic power output is stored in the battery. When the photovoltaic power generation is insufficient or there is no photovoltaic power generation at night, electric energy’s released from the battery for load operation, so as to improve the percentage of electricity generated for in-house use and the self sufficiency rate of household energy, thus saving electricity costs.
Fully Fed to Grid
The PV power generation can be maximised for sale to the power grid. During the daytime when the PV-generated power is greater than maximum output capacity of the inverter, the inverter stays at maximum output while the excess electricity is stored in batteries; when the PV-generated power is lower than maximum output capacity of the inverter or when no PV power is generated at night, the batteries are discharged to ensure that the inverter can maximize the output.
Backup Reserve
If there is a Gateway in the network, you can manually set the “Backup Reserve” value in Haier Smart Cube App. When the grid is connected, the battery stops discharging when the set backup SOC is reached; when the grid is powered down, the battery power from the backup can be used.
Example: Self-Consumption Mode involves backup SOC.
Charge & discharge settings
- Tap the name of the power station to set up on the “Home” screen.
- Click behind the station name, and tap “System Settings” →“Charge &Discharge”to set up the charge & discharge.
| SN. | Parameter name | Description |
| 1 | Charge Cut-off SOC | Set the capacity at which the battery pack stops charging. |
| 2 | Discharge Cut-off SOC | Set the capacity at which the battery pack stops discharging.
|
Reserve capacity setup
Tips
- When there is a Gateway in the networking, the backup capacity parameter can be set up.
- In grid-connected scenarios, the battery pack will no longer be discharged when it is discharged to the backup capacity level. In off-grid scenarios, the battery pack supplies power to the electrical equipment and stops discharging when it reaches the set “Discharge Cut-off SOC”.
- Users set this manually depending on the region’s power failure frequency and the time away from home.
- You are advised not to set this parameter to 0 to avoid irreversible attenuation caused by the battery pack not being charged in time.
- Tap the name of the power station to set up on the “Home” screen.
- Click behind the station name, and tap “System Settings” “Backup Capacity” to set the backup capacity.
Power Station Diagnosis
- Tap the name of the power station to setup on the “Home” screen.
- Click behind the station name, and tap “System Settings” — “Backup Capacity”to detect.
