Energy
Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt
hours). The energy is the power calculated over time. If, for example, your inverter
operates at a constant power of 20,000 W for half an hour and then at a constant
power of 10,000 W for another half an hour, it has fed 15,000Wh 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

Power Factor
Power factor is the ratio of true power or watts to apparent power or volt amps. They
are identical only when current and voltage are in phase than 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.

Note : Fuse Sizing
In any electrical system, fuses are used to protect wiring and equipment from
excessive currents that can cause damage, heating or in extreme cases even fire. If
the fuse rating is too small it could be blown during normal operation. If the fuse
rating is too large, it cannot provide the needed protection. In PV systems, the
minimum and maximum size of the series fuse is determined by the electrical ratings
of the PV module as well as by UL and National Electrical Code (NEC) requirements.
Be sure to consult with your PV module manufacturer for appropriate fuse ratings.
The minimum size of fuses and conductors are calculated using the Short Circuit
Current Rating (Isc) of the PV module. The NEC requires that all fuses and
conductors be sized for a minimum of 1.56 times the Isc of the PV module used in the
system. The proper size PV string fuse is determined by calculating 1.56 x Isc (of the
PV module) and then rounding up to the next standard fuse size.
Example DC fuse rating: If the Isc of the PV module equals 9.6 Adc, then the fuse
size is determined by 1.56 x 9.6 = 14.98Adc. The next standard fuse size would be a
15A, 1000Vdc fuse.

5.7.2 AC Cable Requirements
The cable must be rated in accordance with the local and national codes. The
requirements for the minimum conductor cross-section derive from these
directives. Influencing factors for cable dimension are the following: nominal AC
current, type of cable, cable length, routing method, cable bundling, ambient

7 Electric arc hazards
7.3 Operation step
7.1 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.
7.3.1 Turn the DC & AC Disconnect to position "O".
Wait for the display to go out.
7.3.2 Perform troubleshooting on the PV system:
7.2 Danger information
Check all PV strings for the correct open-circuit voltage.
7.3.3 After the fault is rectified, restart the inverter:
Turn the DC & AC Disconnect to position "I".
Danger of fire from electric arc
Only test the AFCI for false tripping in the order described
below.
Do not deactivate the AFCI permanently.
The inverter has double MPPT’s, it is recommended for each MPPT to work
independently, do not use parallel wiring at DC side (Parallel wiring can make 2
MPPT’s become 1 MPPT, this can improve the efficiency in some cases). If the
MPPT’s are parallel wired at inverter it may cause the AFCI trigger mistakenly.
If an "Error 112" message is displayed, the red LED is permanently lit and the buzzer
alarms, an electric arc occurred in the PV system. The AFCI has tripped and the
inverter is in permanent shutdown.
The inverter has large electrical potential differences between its conductors. Arc
flashes can occur through air when high-voltage current flows. Do not work on the
product during operation.
When the inverter error 112, please follow the steps:
34
7.3.4 If the AFCI self-test is successful:
The PV inverter switches into the "nominal" mode and the green LED is
permanently lit.
7.3.5 If the AFCI self-test is failed:
The following message appears on the display: "Error 114".
Please restart the system, repeat step 1 to step 3.
7.3.6 If the AFCI self-test continues to fail:
Turn the DC Disconnect to position "0" and switch off the AC disconnect switch
to the inverter; contact Growatt to solve this problem.
