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.
Three current transformers are included with the DTSU666-H.
One current transformer is included with the DDSU666-H.
Yes, the hinged current transformers are included as standard.
No, the Smartlogger3000 cannot currently communicate with the power optimisers.
Warranty extensions can be purchased for the inverters in 5-year increments.
The Huawei Smart Battery System (storage system) in combination with the Smart Backup Box automatically starts operation in the following case: PV generator/inverter provides no power / battery 0% capacity / grid failure continues overnight - i.e. the WR starts automatically at 200Vdc the next day *
!IMPORTANT! does not apply to fully optimised systems!
There is no repair in the rare case of a defect you will receive a new device!
If the PV system was connected to the Internet and the FusionSolar server during commissioning on site, you can carry out the updates in the FusionSolar web portal.
In order to operate a Smart Power Sensor with the SUN2000-60KTL-M0, a Smartlogger3000 must be installed. The Smart Power Sensor is then connected to one of the three COM ports on the Smartlogger.
Yes, this is possible with a SmartDongle. However, only the SmartDongle 4G is compatible with the 60KTL-M0 and 100KTL-M1.
No, with the SmartLogger3000 systems can be connected to the Internet via Ethernet/LAN or with a SIM card via the mobile phone network.
No, only the supplied current transformers can be used.
Yes, it is only important that the ‘AFCI’ function is deactivated on the inverter during commissioning on site.
Settings -> Function parameters -> AFCI
Yes, 15% SOC residual capacity is set by default so that a minimum amount of energy is available in backup mode.
Yes, depending on the inverter type, an RCD/FI type A is recommended.
These are as follows:
SUN2000-3-10KTL-M1 -> 100mA
SUN2000-12-20KTL-M2 -> 300mA
SUN2000-30KTL-M3 -> 300mA
SUN2000-36/40KTL-M1 -> 500mA
SUN2000-33KTL-A -> 300mA
SUN2000-36KTL -> 500mA
SUN2000-60KTL-M0 -> 750mA
SUN2000-215KTL-H3 -> 1850mA
If the feature is available on your inverter, it is activated on your device by default.
In principle, this function is not mandatory in Austria, but it is usually recommended to leave it activated.
Yes, after commissioning the inverter, if a backup box is present, the ‘Grid decoupled mode’ function will appear under Settings -> Function parameters.
This must be activated for the emergency power mode to function properly.
Yes, all inverters in the SUN2000 series are equipped with integrated type II overvoltage protection on the AC and DC side.
Yes, the backup box also works without a Luna battery. However, the system makes much more sense with a battery.
The SmartLogger cannot connect to the Internet via WLAN. You can connect to it via a smartphone using the SmartLogger's WLAN signal to make settings.
PEN bracket:
This can be set manually with 4-pole switching using a ‘jumper’ - i.e. zeroing in the backup case is given - 1x RCD is sufficient!
To do this, the inverter must first be accessed using the FusionSolar app and a USB commissioning stick.
After successfully logging in with the ‘extended user’, the required APN data of the Internet provider can be entered in the main menu under Settings -> Communication configuration -> 4G communication.
The communication stick can now be swapped with the 4G dongle.
Attention: The SIM PIN lock must be cancelled beforehand.
In order to activate the DHCP function on the Smartlogger3000, you must connect to the Smartlogger with your smartphone or tablet, as when commissioning the inverter.
To activate the Smartlogger hotspot, the device must be switched off and then switched on again.
After a minute, the device's hotspot will now activate briefly so that you can connect to the Smartlogger3000.
After entering the standard installer password, you will find the corresponding setting under Settings -> Wired network -> DHCP.
The voltage rise suppression can be found under the menu item ‘Function parameters’ in the FusionSolar app and in the Monitoring Portal.
The FusionSolar app must be installed via the Huawei AppGallery.
The app can be downloaded from the following website:
consumer.huawei.com/at/mobileservices/appgallery/
As soon as the Huawei AppGallery has been installed, the FusionSolar app can be downloaded.
The FusionSolar app can be downloaded from the Apple App Store.
Support tools such as TeamViewer and Enspire should be used to configure the DI control and AC feed-in limitation in the Smartlogger. Ensure that the DI ports are set as follows: Go to Setting / DI, select the activation status, define the floating DI1 and activate the Close option. Activate the Trigger shutdown and Trigger startup columns. For the AC limitation, navigate to Settings / Active power control and activate Start. This configuration supports 0%/100% DI control with an external signal line from the grid operator. With two control lines or multiple power levels, an external parking controller is required.
The residual capacity for emergency power operation can be set in the settings under ‘Function parameters’ -> ‘Emergency power SOC’.
We recommend using the FusionSolar web application for this.
