WARNING
• The PV system is not suitable to connect equipment that relies on a stable power supply,
such as medical equipment to sustain life. Ensure that no personal injury is occurred when
the system is disconnected.
• Avoid loads with high starting current like high-power water pumps in the PV system.
Otherwise, the back-up output may fail due to excessive instantaneous power.
• Do not start the BACK-UP function if the PV system is not congured with batteries.
Otherwise, the manufacturer shall not be liable for the related system risks.
• Factors such as: temperature, humidity, weather conditions, etc. may limit the battery's
current and aect its load.
• The inverter supports UPS, and the switching time is less than 10ms. The UPS function may
fail to start if the BACK-UP load capacity exceeds the nomial power of the inverter.
• When single overload protection occurs, the inverter can restart automatically; however,
the restarting time will be extended if it happens several times. For a faster restarting, try it
via App.
• Nomral household loads can be supported when the inverter is in back-up mode. Accepted
loads as below:
• Inductive loads: 1.5P non-inverter air conditioner
• Capacitive load: total power ≤ 0.6 times of the inverter’s nomial output power.

smart meter depends on the inverter.
• Daytime: when the electricity price is at its peak, the battery will power the load rst, 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.
NOTICE
• 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.

03 Product Introduction
User Manual V1.0-2023-05-20
Self consumption mode
• When the power generated in the PV system is sucient, the inverter will supply electricity to
the household load as rst priority. The excess power will then charge the batteries rst, and
still remaining power will be fed back into the grid.
• When the power generated in the PV system is insucient, the battery will supply electricity
to the household load rst. If the battery power is insucient, then the load will be powered
by the grid.
• When the battery cannot supply power, the PV system will supply the loads in priority. If the
PV power is insucient, then the loads will be powered by the grid.
• If neither the PV system nor the battery could supply power, the grid would supply power to
the loads and form BYPASS output.
• When the grid is disconnected and the backup function is disabled, the power generated in
the PV system will supply the loads in priority, and the excess power will charge the batteries.
NOTICE
• For solar power, consider self consumption mode in priority: the excess power charges the
battery in day time; the battery supplies power to the load when there is no solar power
generated at night. This will improve the self consumption rate and saves electricity costs.
• It is suitable for areas with high electricity prices and little or no solar power generation
subsidies.

12
03 Product Introduction User Manual V1.0-2023-05-20
Back-up mode
• When the power generated in the PV system is sucient:
• When the grid works properly, the power generated in the PV system will charge the
battery as priority. The excess power will then supply the household load, and still
remaining power will be fed back into the grid.
• When the grid cannot work properly, the power generated in the PV system will supply
the loads rst. And the excess power will charge the batteries. The battery should supply
the househould load if the PV power is insucient.
• When there is no power generated in the PV system:
• The grid will charge the battery and supply the load when the power grid is normal. (Do
not select this mode if the grid is not allowed to charge the battery according to the local
laws and regulations.)
• The inverter will enter o-grid mode and the battery will supply power to the load when
the grid is abnormal.
NOTICE
• The back-up mode is mainly applied to the scenario where the grid is unstable and there
is an important load. When the grid is disconnected, the inverter turns to o-grid mode to
supply power to the load; when the grid is restored, the inverter switches to on-grid mode.
• The battery stops discharging when it reaches low SOC(State of Charge) level. When the PV
system generates power, the battery will supply power to the load again after it is charged
to a certain SOC level.

power exceeds the Import power limit. The grid continues to power the loads while
the PV system charges the battery in priority.
CThe grid charges the battery between the start time (C) and end time (D). The time is
set in SolarGo app. Refer to the SolarGo app user manual at https://en.goodwe.com.
DAfter D, the PV system keeps charging the battery, but the grid stops charging until
the Battery SOC reaches Peak Shaving SOC.
E The battery enters self consumption mode as the Battery SOC is at or higher than
Peak Shaving SOC. The PV system takes priority to power the loads, and the excess
power charges the battery.
F Under self consumption mode, the battery stops discharging for loads as Peak
