MYPV AC-THOR or AC ELWA-E
my-PV and Huawei recommend communication via a local area network (LAN). The
corresponding control type at my-PV is called “Huawei (Modbus TCP) Manual”.
Alternatively, the AC•THOR could be controlled via Modbus RTU. If a battery
storage is present, then “Huawei (Modbus TCP) Manual” is to be used however
expressly!
Default settings on AC•THOR or AC ELWA-E
Before commissioning, it is essential that you read the assembly instructions
that accompany the device, as well as the operating instructions available on
line.
Find the AC•THOR operation manual here.
Find the AC ELWA-E operation manual here.
Communication of AC•THOR or AC ELWA-E with Huawei via local network
(recommended)
AC•THOR or AC ELWA-E are connected to Huawei in the network via a router.
Within this network, the device receives the information how much surplus PV
power is available from Huawei.
Do not connect the device directly to the inverter or battery system!
When controlled by an inverter, a feed-in meter is required in the system.
Otherwise, the query of the inverter does not provide any data.
Settings on AC•THOR or AC ELWA-E
For the AC•THOR, select “Huawei (Modbus TCP) Manual” for the control type
either on the display or in the web interface. The IP address of the signal
source must then be statically entered on the display under “Ctrl IP”.
Alternatively, these settings can also be made on the web interface of the
AC•THOR. In the web setup, the parameters “Device ID” and “Device Port” can
also be set by Huawei.
For the control “Huawei (Modbus TCP) Manual”, my-PV presets device ID 1 and
device port 502.
For AC ELWA-E, configuration is only possible in the web setup.
The “power timeout” is preset to 60 seconds.
If there is a battery storage (ESS) in the system and it is to be charged with
priority, then the “Target value of the control” should be set to -150 W.
Otherwise, we recommend leaving -50 W.
Settings on Huawei for Modbus TCP with the Smart Dongle
When communicating with Huawei via network, the IP address of the inverter
must not change during operation (e.g. by a DHCP router), otherwise AC•THOR or
AC ELWA-E will lose the control signal!
The following information and illustrations have been kindly provided to my-PV
by Huawei. my-PV cannot guarantee the accuracy of the information or that the
views are up-to-date.
Overview
- All Huawei inverters up to 40kW rated power with SmartDongle WLAN-FE are compatible with MODBUS TCP
- SUN2000 2 to 6 KTL-L1
- SUN2000 3 to 10KLT-MO/M1
- SUN2000 12 to 20KLT-MO/M2
- SUN2000 30 to 40KTL-M3
- Huawei inverter is connected to the router with theSmartDongle WLAN-FE via FE cable (FE = Fast Ethernet) or WLAN in the local network.
- It is recommended to install the latest software version (xxxSPC153 in April 2023) on the SmartDongle WLAN-FE (SDongleA-05); it is recommended to perform the software upgrade in the FusionSolar Portal.
- Afterwards, the communication must be opened in the SmartDongle WLAN-FE so that the values can be read from the inverter via MODBUS TCP. •Display the local IP address of the inverter.
Software Upgrade in FusionSolar Portal
- Read the latest software from SDongleA-05
- Log in to FusionSolar Portal
- Plant – Device management
- Upgrade software from SDongleA-05
- Plants -> Upgrade management > Add
- Update Now • Device Type Dongle
- Targetversion V100R001C00SPC153 or higher
- Select device and check device name
- Confirm – Message «Operation done»
- Progress of upgrade is displayed
- New entry appears in the table, progress is shown in %.
- Resulte: Failed:0, Successful: 1 3
Software Upgrade with APP (Alternative)
- The software upgrade can also be carried out with the FusionSolar APP; however, the method is more complex than in the portal.
- Save V100R001C00SPC153 or higher on the smartphone.
- Upgrade is done on the SmartDongle; therefore connect the FusionSolar APP directly to the SmartDongle.
- WLAN of the SmartDongle is only active for a few minutes; check in the Android settings whether the WLAN with SSID SDongleA-HVxxx is visible.
- If the WLAN is not visible, disconnect the SmartDongle from the inverter and reconnect it, wait a while until SDongleA-HVxxx appears.
- Connect with SmartDongle • FusionSolar APP-> | – Commissioning
- Scan QR code of SmartDongle WLAN -FE – WLAN Password= Changeme
- Login Installer and password 00000aSmartDongle appears in the picture)
- Maintenance > Devices up to date (update)
- Global Search -> SDongleV100R001C00SPC153_package or higher
- Upgrade freeze step is displayed
- SmartDongle restarts after approx 10 minutes
Please always use the latest APP version!!!
Enable Communication in FusionSolar Portal
With the SmartDongle software XXSPC153 or higher, energy management systems
car control the SUN2000 inverter via MODBUS TCP (read and write). Port 502 is
used for this purpose. This is closed by default and must be opened.
SmartDongle MODBUS TCP open
- In FusionSolar Portallogin
- Choose Plant-
- Switch to the register Devices
- SmartDongle choose
- Parameter settings
- Register access parameters
- Connection / MODBUS TCP «Enable (unrestricted »
- Settings
Enable Communication with APP (Alternative)
With the XxSPC153 SmartDongle software, energy management systems can control
the SUN2000 inverter and the LUNA2000 battery via Modus (read and write). Port
502 is used for this purpose. This is closed by default and must be opened for
SolarManager.
Modus TCP enable
- Connect to inverter (QR Code)
- Settings – Communication configuration
- Dongle-Parametereinstellungen
- Modbus-TCP
- Change to «Enable (unrestricted)» * Confirm
Read out IP address from APP
- The IP address of the inverter in the local network can ONLY be read out with the FusionSolar APP
- Read IP address • Connect FusionSolarAPP to the inverter (QR code)
- Settings -> Communications configuration
- Select Router connection settings
- Select WLAN connection or FE connection (LAN cable)
- Expand details > IP-Adress Read
Read out MODBUS ID from APP
- ID-Adress Read
- Connect FusionSolarAPP to the inverter (QR code) – Settings
- Communications configuration – RS485 1
- Com adress is also the MODBUS TCP address
The inverter with the Smart Dongle usually has the address 1 and the other inverters a higher number. Please check! Please always use the latest APP version!!!
Communication of AC•THOR with Huawei via Modbus RTU
If the Huawei Smart Dongle is used on the inverter, communication problems may
occur with this type of connection. We therefore recommend using the control
type
Huawei (Modbus TCP) Manual” if possible (see chapter 2), especially if a
battery storage is available!
The control signal is received via Modbus RTU (RS485, A B GND).
Use shielded twisted pair cable!
RTU bus must be provided with a 120 Ohm terminating resistor!
(Not included in the scope of delivery)
When controlling via Modbus RTU, the operating mode M7 cannot be used!
With the AC•THOR, select “Huawei (Modbus RTU)” for the control type either on
the display or –
if a network connection is available – in the web interface.
