3.2 Application Scenarios
WARNING
• 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.
• BACK-UP function is not recommended if the PV system is not congured with batteries.
Otherwise, the risk in system power usage is beyond the equipment manufacturer's
warranty scope.
• Factors such as: temperature, humidity, weather, etc. may limit the battery's current and
aect its loading capacity.
• 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.
• When the grid is disconnected, the o-grid function of the inverter will be closed
automatically if the load capacity exceeds the inverter's rated power; to enable it, turn o
the large loads and ensure the load power is less than the rated power of the inverter.
• The BACK-UP output port of the inverter has the overload capability and UPS functionality
(the switching time is <10 ms). It can provide to the normal household load when the grid
is disconnected. To ensure the stability of UPS switching and load power supply, avoid
using loads with higher starting current, such as high-power pumps. The supported loads
are as follows:
• For GW 3000-ES-20, GW 3600-ES-20, GW 5000-ES-20, GW 6000-ES-20, GW 3600-SBP-20,
GW 5000-SBP-20 and GW 6000-SBP-20: the total power of inductive load and capacitive
load is no more than the inverter's rated output power.
• For GW3600M-ES-20, GW5000M-ES-20 and GW6000M-ES-20: the total power of inductive
load and capacitive load is ≤ 0.5 times of the inverter's rated output power.

3.3 Working Mode
3.3.1 System working mode
• Day: when the electricity price is in the peak, use the battery to power the load rst, and the
remaining power can be sold to the grid.
• Night: when the electricity price is in the valley, set the time for the grid to charge the battery.
Economic mode
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 dierence between peak
and valley electricity prices is big.

10
03 Product Introduction User Manual V1.0-2022-07-20
• Day:
• When the power generated in the PV system is sucient, it supplies the household load
as priority. And the excess power charges the batteries rst. The remaining power will be
sold to the grid.
• When the power generated in the PV system is insucient, use the battery supplies the
load rst. If the battery power is insucient, then the load will be powered by the grid.
• Night:
If the battery power is sucient, the load will be powered by the battery. If the battery power
is not enough, the load will be powered by the grid.
Self consumption mode
NOTICE
• For solar power, consider self consumption mode as 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. It improves 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.

11
03 Product IntroductionUser Manual V1.0-2022-07-20
• When the power generated in the PV system is sucient, it charges the battery as priority.
And the excess power charges the load. The remaining power will be sold to the grid.
• When there is no power generated in the PV system:
• The grid supplies the load when the power grid is normal.
• The inverter enters o-grid mode and the battery supplies power to the load when the
grid is abnormal.
Back-up mode
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 SOC. When there is sunlight the next day,
the battery starts to supply power to the load after it is charged to a certain power level.

3.3.2 Inverter operation mode
No. Parts Description
1 Waiting
mode
Waiting stage after the inverter is powered on.
• When the conditions are met, it enters the self-check mode.
• If there is a fault, the inverter enters the fault mode.
2 Self-check
mode
Before the inverter starts up, it continuously performs self-check,
initialization, etc.
• When the conditions are met, it enters the grid-tied mode, and the
inverter starts on grid connection.
• If the grid is not detected, it enters the o-grid mode and the inverter
runs o-grid; if the inverter has no o-grid function, it enters the wait
mode.
• If the self-check is not passed, it enters the fault mode.
3 Grid-Tied
mode
The inverter is grid-tied successfully.
If the grid is not detected, it enters the o-grid mode.
If a fault is detected, it enters the fault mode.
If the conditions do not meet grid-tied requirements and the o-grid
output function is not turned on, it enters the wait mode.
4O-grid
mode
When the grid is powered o, the inverter switches to the o-grid mode
and continues to supply power to the load via BACK-UP port.
If a fault is detected, it enters the fault mode.
If the conditions do not meet grid-tied requirements and the o-grid
output function is not turned on, it enters the wait mode.
If the conditions meet grid-tied requirements and and the o-grid output
function is turned on, it enters the self-check mode.

3.4 Functionality
For a safe operation, the inverter will automatically reduce the output power when the operating
environment is not ideal.
The following are the factors that may occur power derating. Please try to avoid them during
usage.
• Unfavorable environmental conditions, e.g., direct sunlight, high temperature, etc.
• Inverter's output power percentage has been set.
• Over-frequency derating.
• Higher input voltage value.
• Higher input current value.
Power derating
Reason to occur electric arcs
• Damaged connectors in PV or battery system.
• Wrong connected or broken cables.
• Aging connectors and cables.
Method to detect electric arcs
• The inverter has an integrated AFCI function.
• When the inverter detects an electric arc, users can nd the time of the fault and the detailed
phenomenon through the app.
• The alarm can be cleared automatically if the inverter triggers a fault for less than 5 times
within 24 hours. The inverter locks for protection after the 5th electric arc fault. The inverter
can operate normally after the fault is solved. Please refer to the PV Master App User Manual
for detailed operation.
AFCI
The inverter reserves a dry contact controlling port, which supports connecting additional
contactors to enable/disable the load.
The load control methods are as follows:
• Time control: set the time to enable/disable the load, and the load will be turned on or o
automatically within the setting time period.
• Switch control: when the control mode is selected as ON, the load will be enabled; when it is
set as OFF, the load will be disabled.
• BACK-UP load control: the inverter has built-in DO dry contact controlling port, which can
control whether the load is o or not by contactor. In o-grid mode, the load connected to
the DO port can be turned o if the overload at the BACK-UP end is detected or the battery
SOC value is lower than the battery o-grid protection setting.
