Step 8 - Complete The Apsystems Installation Map - APsystems QT2-AU User Manual

4. APsystems Microinverter System Installation

4.3.8 Step 8 - Complete the APsystems installation map

a. Each APsystems Microinverter has 2 removable serial number labels.
b. Complete installation map by sticking ID label of each microinverter at the right
location.
c. The second serial number label, could be stuck on the solar module frame, which
could help later to confirm the position of the microinverter without dismantling the
PV module
①. The layout of the microinverters' serial numbers installation map is only suitable for
typical installation
②. Installation Map is available in the last page appendix of this manual.
③. Use ECU_APP (available in the EMA Manager) to scan the serial numbers on the map
when setting up the ECU (see ECU instruction manual for more info).
Power Quality Response Modes
AS 4777.2:2020 Clause 3.3 specify requirements relating to an inverters capability to
contribute to maintaining the power quality at the point of connection or to provide support
to a grid. The intent of volt response modes is to vary the output power of the inverter in
response to the voltage at its terminals.
Power derating for voltage variation (Volt-Watt mode)

The inverter power output will vary in response to the AC grid voltage.This is switched
on by default.
(Details of how to enable this mode are contained in the "APsystems ECU-R Install & User
Manual" or "APsystems ECU-C Install Manual & User Manual", which can be accessed at our
website at https://aunz.apsystems.com/resources/library/.)
Reactive power regulation for voltage variation (Volt-VAr mode)

The power output or input will vary in response to the AC grid voltage. This function is
switched off by default.
(This mode can be enabled via the configuration App. Please refer to the "APsystems ECU-R
Install & User Manual" or "APsystems ECU-C Install Manual & User Manual" on our website at
https://aunz.apsystems.com/resources/library/, or contact Technical Support for more
information.)
Once the power quality and grid se ttings have been selected at commissioning they are
locked to view only.
These settings can be unlocked at a later date in order to update the settings for
changing requirements and in case of wrong settings being entered and requiring
adjustment upon inspection.
