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.
• 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 SPDT switch:
• For GW100K05-BTC, GW100K06-BTC, and GW100K07-
BTC: the nominal current is ≥250 A and the nominal
voltage is ≥415 V
Depends on the actual using load.
Specifications of the AC breaker depend on the nominal
output current of the grid-tied PV inverter.
The smart meter can be purchased from the inverter
manufacturer. Recommended model: GM3000C.
• 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.
