1.3.3 Glossary
AC
Abbreviation for "Alternating Current”
DC
Abbreviation for "Direct Current”
Energy
Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt hours).
The energy is power multiplied by time. For example, if the inverter operates at a
constant power of 4600 W for 30 minutes and then at a constant power of 2300 W for
30 minutes, it would have generated a total energy output of 3450 Wh in that hour and
fed it into the power distribution grid.
Power
Power is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an
instantaneous value. It displays the power that the inverter is currently feeding into the
power distribution grid.
Power rate
Power rate is the ratio of current power fed into the power distribution grid and the
maximum power of the inverter that can be fed into the power distribution grid.
Power factor
Power factor is the ratio between real power (measured in watts) and apparent power
(measured in Volt-Amps). When the current and voltage are in phase, the power factor is
1.0. In an AC circuit, the power is not always equal to the direct product of volts and
amperes due to reactive components. In order to find the true power of a single-phase
AC circuit, the product of volts and amperes must be multiplied by the power factor.
PV
Abbreviation for photovoltaic.
Wireless communication
The external wireless communication technology is a radio technology that enables
communication between the inverter and other communication products. The external
wireless communication does not require line of sight between the devices and it is a
selective purchasing option.

6.10 AFCI (Optional)
6.10.1 Arc-Fault Circuit Interrupter (AFCI)
In accordance with the National Electrical Code R, Article 690.11, the inverter has a
system for the recognition of electric arc detection and interruption. An electric arc with
a power of 300 W or greater must be interrupted by the AFCI within the time specified by
UL 1699B. A tripped AFCI can only be reset manually. You can deactivate the automatic
arc fault detection and interruption (AFCI) via a communication product in "Installer"
mode if you do not require the function. The 2011 edition of the National Electrical Code
R, Section 690.11 stipulates that newly installed PV systems attached to a building must
be fitted with a means of detecting and disconnecting serial electric arcs (AFCI) on the PV
side.
6.10.2 Danger information
Be aware of fire caused by the electric arc
Only test the AFCI for false tripping in the order described below.
Do not deactivate the AFCI permanently.
If the "Error 200" message is displayed and the buzzer alarms, it indicates that an
electric arc has occurred in the PV system. The AFCI will be tripped, and the inverter is in
a permanent shutdown state. The inverter has significant electrical potential
differences between its conductors, which can result in arc flashes when high-voltage
current flows. Please do not perform operations on an inverter in operation.
The inverter has large electrical potential differences between its conductors. Arc has
flashes can occur through air when high-voltage current flows. Do not work on the
product during operation.
Whenthe inverter reports Error 200, please perform the following steps:
6.10.3 Operation step
6.10.3.1 Turn the DC & AC Switch to the position "OFF".
6.10.3.2 Perform troubleshooting on the PV system:
Wait until the screen is off.
Check if the open-circuit voltage of the PV strings is within the permissible range.
6.10.3.3 After the fault is rectified, restart the inverter:
Turn the DC & AC Switch to the position "ON".

6.11 Backup function (Optional)
The MID-XH series inverters can work in backup mode. In this mode, the inverter can
output power of 230/400 V, 50/60 Hz to the load when the grid goes down. To enable
this mode, you need to install a backup box. The system diagram is shown below:
Fig 6.19
6.9 GFCI (Standard)
6.9.1 Ground fault circuit interrupter (GFCI)
The inverter is equipped with a residual-current device. When the leakage current is over
300 mA and lasts for over 300 ms, the inverter will report Fault 201 and displays
"Residual I High".
The inverter features the function of detecting residual current and protecting the
inverter against residual current. If you need to install an external AC breaker which
supports residual current detection, you are advised to install a Type A RCD breaker with
the rated residual current greater than 300 mA.

1. Turn on the DC switch on the inverter. Once the input DC voltage is greater than 160V,
the inverter will display "No AC connection" and the LED indicator will turn red.
If other error message is displayed, please refer to Section 13. If you encounter any
technical problems, please contact Growatt support.
2. Turn on the circuit breaker or the switch between the inverter and the grid, the inverter
will start a countdown to perform a self-check. If no fault is found, the inverter will be
connected to the grid.
3. When the inverter is working properly, the leaf-shape indicator will turn green.
4. Finish the commissioning process.
8 Working Mode
8.1 Operating mode
In this mode, the inverter works normally.
ØWhen the grid-connected requirements are met - the DC voltage is greater than
200V, and the grid voltage and frequency are within the permissible range, the
inverter will convert the DC power generated by the solar panels into AC power and
feeds it to the grid with the green LED indicator on.
ØWhen the DC voltage falls below 160V, the inverter will automatically disconnect
from the grid and exit the operating mode. It will enter the operating mode and be
connected to the grid automatically once the requirements are met.
8.2 Failure mode
When an unexpected condition occurs, such as a system failure or an inverter failure, the
inverter will report the error message on the screen. In failure mode, the leaf-shape
indicator will turn red and the inverter will be disconnected from the grid.
When PV power is insufficient or no PV power is generated, the inverter will shut down
automatically. In shutdown mode, the inverter does not consume energy from the grid or
the solar panels, and the display and the indicators will be off.
