3.3 Working Mode

3.3.1 System working mode

Economic mode
• Select Economic mode only when it meets the local laws and regulations, e.g., whether the
grid is allowed to charge the battery. If not, do not use this mode.
• It is recommended to use economic mode in scenarios when the peak-valley electricity price
varies a lot.
• Daytime: when the electricity price is at its peak, the battery will power the load first, and the
remaining power can be sold to the grid.
• Night: when the electricity price is at its valley, set the time for the grid to charge the battery.
• For one inverter model, specifications of the BACK-UP load
breakers and ON-GRID load breakers shall be the same. AC
circuit breakers should be prepared by the customers.
• An SPDT switch is recommended to ensure that the BACK-
UP loads do not stop working when the inverter is off or in
maintenance.
• Recommended specifications of AC circuit breaker and SPDT:
• For GW5K-BT and GW6K-BT: the nominal current is ≥25A and
the nominal voltage is ≥400V
• For GW8K-BT and GW10K-BT: the nominal current is ≥32A and
the nominal voltage is ≥400V
Specifications of the AC breaker depend on the rated output
current of the Grid-Tied PV inverter.
Depend on the actual using load.
Included in the deliverables of the inverter. Recommended model:
GM3000.
• When a GoodWe inverter is applied, GM3000 is recommended.
• When the inverter is from other manufacturer, model of the
smart meter depends on the inverter.
