Find quick and easy answers to frequently asked questions about the products and
solutions from Huawei FusionSolar. Whether inverters, battery storage, optimizers,
backup boxes or accessories - here you will find all the answers online.
In order to determine the correct polarity (PV+; PV-), a resistance or impedance measurement must be carried out on the string.
The procedure is explained in detail in the enclosed operating instructions.
Activation takes place by selecting the system in the overview display and pressing the ‘Kiosk’ button at the top right.
If migration is not possible, the system owner must unbind the system via the FusionSolar app so that the new installer can add it to their account.
The charger must be put into operation with EMMA. If no IAC meter appears, reset the charger to the factory settings and put it into operation via EMMA.

The inverters are each connected to pins 1 (RS485A +) and 3 (RS485B -) to 2 (RS485A +) and 4 (RS485A -), whereby it must be ensured that, starting from the master inverter, the cables are always connected from pins 1 and 3 to 2 and 4.
Please note that the SLAVE inverters must be commissioned first using the FusionSolar app and the MASTER inverter last.
When commissioning the MASTER inverter, please add the cascaded inverters under device management during commissioning and complete commissioning.
ATTENTION:
When using a Smartlogger3000, all devices can be commissioned together.
To commission an inverter, the FusionSolar app must be downloaded to a smartphone or tablet.
If a Smartlogger3000 is installed in the system, commissioning must be carried out using a laptop/PC via the integrated web interface.
For more information on commissioning, you can find an instruction video with the FusionSolar app here:
www.youtube.com/watch
To connect to the Smartlogger3000, you must connect to the LAN port of the Smartlogger with a PC using a network cable.
To access the Smartlogger interface, the following address must be entered in the address line of the browser:
192.168.8.10
A physical layout can be created by pasting, photographing and then uploading the physical template layout included in the scope of delivery to the FusionSolar portal.
A physical layout can also be created manually in the FusionSolar Monitoring Portal.
Please contact your responsible PV installer for this.
They can grant you access to monitor your system via FusionSolar.
Simply send an e-mail with the desired user name and e-mail address to support@ske-solar.com.
This will make you part of the SKE structure and give you faster support and many other benefits.
The settings can only be made in the owner account via the app. Switch off the Shelly device (DO contact, heating cartridge) first during commissioning. Determine the PV surplus threshold for each Shelly device in the EMMA PV current settings and set a schedule. Activate the ‘PV surplus’ function (PV power preferred) to enable automatic switching. Ensure that the Shelly is switched off manually before configuring the above parameters. Once configured, the Shelly will switch on automatically if there is sufficient surplus. If it is switched on manually, it reacts to dynamic switching. If the PV surplus threshold is changed, the schedule must be deactivated and then reactivated. Parameter adjustment is limited to 3 times per day for safety reasons. Ensure that the ‘Maximum grid power’ setting in the ‘System settings’ is configured correctly so that the Shelly is switched off depending on the grid power consumption if the power consumption exceeds the set value.
The licence can be obtained from your dealer.
Check whether the inverter and the LUNA have separate PE conductors with a sufficient cross-section to the house potential equalisation busbar. Ensure that there is no AC grid zero offset due to poor PEN earthing or faulty N conductor connections. An alarm can also occur due to poor house earthing, so a loop impedance measurement of the house earthing system should be carried out even if the inverter and the LUNA are not connected to the main equipotential bonding bar via separate PE conductors. In the event of a Huawei alarm, check the voltage at earth on a TN grid and ensure that the N conductor is connected correctly. Measure the voltage of the N conductor to earth and check the phase voltages L1-L3 on the inverter. This alarm often occurs in conjunction with alarm #2034 (grid overvoltage) or alarm #2032 (grid loss).
The arc fault alarm (DC-arc fault) is triggered when an arc is detected, whereupon the inverter switches off automatically to prevent major damage. This alarm does not disappear automatically and must be acknowledged separately and checked on site. To process the alarm, you should click on the alarm message and follow the steps indicated. Firstly, you should check whether someone has already been on site. It is also important to check the DC connections and the MC4 connections and to take photos of the string connections on the inverter. Often the alarm also occurs in the area of the surge arrester box or the generator connection box. Pay attention to which DC connectors were used and document this with photos. Furthermore, DC RISO measurements should be carried out with a PV measuring device and the measurement results should also be photographed. Finally, it is important to check the DC string configuration to ensure that no parallel strings are connected to the same MPPT-WR input and that the 3G rule is observed. Also pay attention to possible negative DC equalisation currents.
This function is reserved exclusively for the FusionSolar Web Application (html5 version).
To do this, the ‘Upgrade management’ must be opened in the ‘Attachments’ menu.
Then click on ‘Add’ and complete the required fields.
Attention: This function is only available to installers of the system.
To establish a connection with the dongle, the dongle must be unplugged from the inverter and plugged in again. After approx. one minute, a WLAN hotspot of the dongle can be found, which is active for 2 minutes. Now, when commissioning the device, the QR code of the dongle must be scanned instead of the QR code on the inverter.
As soon as you have logged into the dongle as an installer, you will find the corresponding entry for updating the device under the menu item ‘Maintenance’.
You can request the latest firmware version via the SKE support channel.

A maximum of 10 devices can be operated per dongle, with each SUN2000 inverter, each LUNA2000 battery and the Smart Power Sensor being counted as one device.
Two LUNA batteries with 15kWh each can be connected to each compatible inverter.
This results in a total capacity of 30kWh per inverter.
