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.
The Smartlogger 3000A01EU does not support AC-MBUS PLC communication.
The Smartlogger 3000A03EU supports AC-MBUS PLC communication.
The internal diameter of the supplied current transformers is 24 mm.
As described in the SUN2000-450W-P data sheet, at least the following number of optimisers must be installed in a fully optimised system:
3-10KTL-M1, 12-13KTL-M2: 6x SUN2000-450W-P
2-6KTL-L1: 4x SUN2000-450W-P
The Blackstart button is irrelevant for normal operation, as the battery is automatically activated by the inverter's enable signal. If the enable signal does not work, for example due to a cable break, the battery can be temporarily started manually using the black start button.
The Smart IV-Curve diagnostic function can be activated in FusionSolar with a licence. It analyses the ageing condition and status of the PV system and generates automatic reports, which are of great benefit in the area of operation and maintenance.
100% of the storage capacity can be utilised. With a 15kWh battery system, 15kWh can be discharged.
The Luna must first be recognised in the quick settings for the slave. The cascaded inverter is then recognised.
The optimizer search must first be carried out in the quick settings of the slave inverter. The cascaded slave inverter is then recognised during quick commissioning.
To connect to the Internet, the Ethernet cable must be connected to the WAN connection.

The Huawei Smart Power Sensor must be integrated between the meter (or post-metering fuses) and the loads in the house.

Power meters from third-party providers can only be used when using a SmartLogger.
The list of compatible power meters can be found in the SmartLogger operating instructions.
EMMA must be connected to the pins RS485A - PIN 14 and RS485B1 - PIN 7, not to the same pins as the Smart Power Sensor.
The MB0 inverter must first be updated to the latest version to ensure that the inverter automatically recognises the baud rate of the Smart Meter and the Luna. This is necessary as the MB0 series has a default baud rate of 115200.
The FusionSolar app is not available in the Google Play store.
You can install the FusionSolar app from the Huawei App Gallery on Huawei devices.
On other Android devices, you can also install the Huawei App Gallery and then the FusionSolar app. This also makes it easy to update the FusionSolar app.
Check the RS485 bus cabling and ensure that COM port pins 9 and 10 are connected correctly, as these form the bus input and output.
Check the EMMA voltage connection for the correct installation location and the correct phase sequence, ensure that the EMMA firmware is up-to-date, check the ‘System configuration’ / ‘Internal meter’ setting in the app if the dongle was previously used, carry out updates for the inverter and the EMMA and follow the new commissioning instructions from SKE/Julien Poredos.
If the Chint DTSU666-H 250A/50mA Power Meter shows no consumption, the communication to the Power Meter is interrupted and the communication connection should be checked.
If the inverter does not provide any output power, this may be due to a battery status test, during which the battery charges and discharges 100% from the grid. There is no PV production during this test. This process is carried out once per battery pack and can take up to 48 hours. The system should then run normally again. If the process is interrupted, it starts again from the beginning.
This can be caused by an incorrect phase assignment, an incorrect configuration or too high a load.
Carry out an MBUS update of the inverter and, if necessary, an optimiser update. Then start a new optimiser search.
