Energy
Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt hours).
The energy is the power calculated over time. For example, your inverter operates at a
constant power of 4600 W for half an hour and then at a constant power of 2300 W for
another half an hour, it has fed 3450Wh of energy into the power distribution grid within
that hour.
Power
Power is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an
instantaneous value. It displays the power your inverter is currently feeding into the
power distribution grid.
Power rate
Power rate is the radio of current power feeding into the power distribution grid and the
maximum power of the inverter that can feed into the power distribution grid.
Power factor
Power factor is the ratio of active power or watts to apparent power or volt amps. They
are identical only when current and voltage are in phase then the power factor is 1.0. The
power in an ac circuit is very seldom equal to the direct product of the volts and amperes.
In order to find the power of a single phase ac circuit the product of volts and amperes
must be multiplied by the power factor.
Wireless communication
The external wireless communication technology is a radio technology that allows the
inverter and other communication products to communicate with each other.The
wireless communication device is not standard. Require to order extral if you need it.

6.9 Backup(optional)
Backup means that the inverter can output 230/400V, 50/60Hz voltage to the load when
there is no grid. The MOD-XA inverter has the Backup function. If you need to use this
function, you need an additional Backup box. The system diagram is as the figure below.
Fig 6.14
6.8 GFCI(Standard)
This inverter includes an integrated residual current device .If the leakage current is
over 300mA and last for more than 300ms,the inverter will report 201 fault and the
OLED will display Residual I High.
The inverter has the function of detecting residual current and protecting the inverter
against residual current. If your inverter must equip a AC breaker which has the function
of detecting residual current ,you must choose a Type A RCD breaker with the rating
residual current more than 300mA.

backup function requires a backup box provided by Growatt.
Debugging 7
1.After connecting the battery (at least three ARK batteries) and turning on the
switch,the inverter display will show the following information:No AC connection
error,the inverter LED will turn red.
If other information is displayed,please refer to Chapter 13.If you encounter any
problems during the debugging process and cannot solve it,please contact customer
service.
2.Close the circuit breaker or switch between the inverter and the grid, the inverter
will start a countdown to the self-check,and after the self-check is normal,it will be
connected to the grid.
3.In normal operation,the leaves of the inverter indicator window will turn green.
4.Finish debugging.
Working Mode 8
8.1 Normal mode
In this mode, the inverter works normally.When the battery and the grid are connected
normally, the inverter counts down and connects to the grid, and the green light is on.
8.2 Failure mode
The inverter controls the chip monitors and adjusts the state of the system in real time.
When the inverter monitors any unexpected conditions,such as system failure and
inverter failure,the display will show the fault information.In the failure mode,the
inverter will indicate the leaves of the window will turn red and the inverter output will
be disconnected from the grid.
