Battery Settings

Setting battery-related parameters can optimize battery performance, extend battery life, and achieve intelligent charging and discharging strategies.

Charging Source Prority

• The battery acquires power according to the set order.

• By default priority, PV is placed before Grid, PV solar charges the battery first, Grid supplements the remaining charge.

• In the negative electricity price scenario, Grid can be adjusted to be before PV.

Discharging Source Prority

Battery releases power according to the set order. The battery discharge priority can be configured based on the actual situation.

Battery Level Setting

No.	Parameter name	Description
1	Charge Cut-off SOC	Sets the capacity at which the battery pack stops charging.
2	Discharge Cut-off SOC	Sets the capacity at which the battery pack stops discharging. Value 0% is recommended for this parameter. The priority is given to "Backup Capacity" in backup system wiring mode, while the parameter is applied in non-backup system wiring mode.
3	Peak shaving	Set the battery peak shaving cutoff point.
4	Backup Reserve SOC	You can set this parameter when a gateway exists in the system wiring. In the on-grid scenario, the battery pack stops discharging when the backup capacity value is reached. In the off-grid scenario, the battery pack supplies power to power device and stops discharging when the Discharge Cut-off SOC setting is reached. Users can manually set this parameter according to the power interruption frequency of their regions and leave time. Value 0 is not recommended for this parameter to avoid irreversible attenuation due to failure to charge the battery pack in time.

Battery Preheating scheduling

Pre-adjust the battery temperature to the optimal working range in low temperature environments to prevent performance degradation and safety hazards caused by low temperature.

Residential Energy Storage Station

No.	Parameter name	Description
1	Battery Preheating Scheduling	When set to , the scheduled heating time periods for the battery heating film can be set.
2	Heating	Click to add scheduled heating time periods for the battery heating film.

Commercial & Industrial Energy Storage Station

After Battery Preheating Scheduling set to, the preheating mode needs to be selected.

Manual Setting

In manual mode, it is necessary to manually set the scheduled heating time periods for the battery heating film and the expected charging and discharging power.

No.	Parameter Name	Description
1	Preheating	When set to, activates the scheduled heating function for the battery heating film.
2	Heating	Click to add scheduled heating time periods for the battery heating film.
3	Target Charging Power	Due to low temperatures limiting battery charging power, heating stops when the charging capability exceeds this value after heating starts.
4	Target Discharging Power	Due to low temperatures limiting battery discharging power, heating stops when the discharging capability exceeds this value after heating starts.

Depends on System (Automatic)

Automatic mode is only supported when the station is in TOU scheduling mode.

Battery Power Limit

If you need to set more detailed charging and discharging data, you can set this parameter.

No.	Parameter name	Description
1	Battery Max Charging Power	Set the maximum charging input power allowed by the battery.
2	Battery Max Discharging Power	Set the maximum discharging output power allowed by the battery.

Battery Automation

If this parameter is set, the battery will prioritize executing the parameters set by Battery Automation.

No.	Parameter name	Description
1	Add Time Period	Click to add Time Period.
2	Add your action	Click to add battery operation status. Battery Charging Maximum Charging Power: Set the maximum total input power allowed for the battery charging, including all charging sources. Maximum Charging Power From grid to BAT: Set the maximum charging input power from Grid to BAT. This parameter must be ≤ Maximum Charging Power. Battery Charging From Grid Cut-off SOC: When the battery SOC reaches this threshold, the grid is forced to stop charging the battery. Battery Charging Source Priority: Adjust the battery energy source priority. Battery Discharging Maximum Discharging Power: Set the maximum total discharging output power allowed for the battery. Maximum Discharging Power from BAT to Grid: Set the maximum discharging output power from BAT to Grid.This parameter must be ≤ Maximum Discharging Power. Discharge Cut-off SOC from BAT to Grid: When the battery SOC reaches this threshold, the BAT is forced to stop transmitting power to the grid. Battery Preserve: Maintain the current SOC without change. Battery Self Consumption: The electrical energy of the battery is prioritized for supplying the load, and the remaining energy is sold to the power grid. Maximum Charging Power: Set the maximum charging input power from PV to the battery. Maximum Discharging Power: Set the maximum discharging output power of the battery to the household load.
