5.8 Commisioning
Start inverter:
Start inverter after checking all below steps:
·
Check that the device is fixed well on the wall.
·
Make sure all the PV wiring and the AC wiring are completed.
·
Make sure the meter are connected well.
·
Make sure the battery is connected correctly.
·
Turn on the external AC, DC switch.
·
Turn on the DC switch to the ‘ON’ position.
·
Set sysswitch on the screen of the inverter to ‘Turn on’
·
Inverter will start automatically when the PV panel generate enough energy or the battery is charged.
·
Check the status of LED and LCD screen, first LED should be green and the LCD screen should display the main interface.
·
If first LED is not green please check the below:
-All the connections are right.
-All the external disconnect switches are closed.
-The DC switch of the inverter is in the ‘ ON ‘ positon.
·
Enter the setting interface.
·
Set the safety standard as page 28; Set the system time as page 27; PV connection mode as page 28; Set the work mode as
page 27; Set the communication address as page 28; Set the EPS as page 26; Set WIFI according to the wifi manual;
NOTE!
Please set the inverter if it is the first time to start up.
Above steps is for the regular start-up of the inverter. If it is the first time to start up the inverter ,
you need to start up the inverter.
4. DRED
This application meets the requirements of local Australian grid code (AS/NZS 4777.2) which, among specific requirements for
connection, calls for compatibility with Demand Response Enabling Devices (DRED). The DRED is under control of a local
network operator and allows to put the inverter in one of the Demand Response Modes (DRMs) defined by the standard:
·DRM 0 Operate the disconnection device
·DRM 1 Do not consume power
·DRM 2 Do not consume at more than 50% of rated power
·DRM 3 Do not consume at more than 75% of rated power and source reactive power if capable
·DRM 4 Increase power consumption (subject to constraints from other active DRMs)
·DRM 5 Do not generate power
·DRM 6 Do not generate at more than 50% of rated power
·DRM 7 Do not generate at more than 75% of rated power and sink reactive power if capable.
·DRM 8 Increase power generation (subject to constraints from other active DRMs)
Currently, it is mandatory to respond to DRM0, which allows the network manager to remotely decouple the installation from
the distribution network.

1. WIFI or GPRS
Connect the WIFI/GPRS module produced by Renac to the
COM port and install the antenna to the terminal cover.
After successful connection, information such as power
generation and running state of the inverter can be
viewed via the App on the phone. The details please refer
to the module user manual.
