Grid Settings
Setting grid-related parameters can ensure safe grid connection, compliant electricity sales, and maximum revenue.
Grid Exporting Priority
By default priority, PV is placed before Battery. PV power prioritizes grid feed-in, with battery supplementing grid sales.
In the negative electricity price scenario, Battery can be adjusted to be before PV.
The device sells electricity to the grid according to the set order.
Grid power setting
1
Grid Export Power Limit
Set the system's maximum power for selling electricity to the grid.
2
Grid Import Power Limit
Set the system's maximum power for buying electricity from the grid.
Peak Shaving
The electricity bill in some regions is calculated as follows: Total electricity bill = Cost at peak power + cost for electricity usage + other costs. Wherein, peak power refers to the maximum power imported from the grid. This mode is suitable for areas with peak and valley electricity prices and significant price differences.
The Peak Shaving function can be used with all working modes, configuring the maximum peak power drawn from the grid to reduce the maximum peak power drawn from the grid during peak periods, thereby lowering the electricity bill.
Active Power Control
1
Peak shaving SOC
This parameter setting affects the capacity of peak shaving, and the system charges the battery to the set SOC value during the off-peak period. The larger the parameter setting, the stronger the peak shaving capability.
2
Schedule
A maximum of 24 timetables can be added.
3
Maximum Peak Power
Set the maximum peak power for drawing electricity from the grid for household loads and battery packcharging.
Example 1: Self-Consumption Mode Settings for Peak Shaving
Assume that the peak shaving SOC is set to 50% and the maximum peak power is 2kW. Because Total electricity bill = Cost at peak power + cost for electricity usage + other costs. Wherein, peak power refers to the maximum power imported from the grid. After Self-Consumption Mode is set to Peak Shaving, the power purchased from the grid drops from 5 kW to 2 kW, so the total electricity bill is reduced.
Example 2: Time-based Control Mode Settings for Peak Shaving
Assume that the peak shaving SOC is set to 50% and the maximum peak power is 2kW. Because Total electricity bill = Cost at peak power + cost for electricity usage + other costs. Wherein, peak power refers to the maximum power imported from the grid. After Time-based Control Mode is set to Peak Shaving, the power purchased from the grid drops from 5 kW to 2 kW, so the total electricity bill is reduced.
