Frequently Asked Questions.
Q: Can AI mode work with my feed-in tariff?
A: Yes, AI mode can work with your feed-in tariff. Through the open API, SIGEN AI will automatically access the dynamic utility rate platform and obtain dynamic electricity price data provided by power operators. By analyzing the system's operating data and local electricity price information, the AI mode can automatically adjust the system's operating strategy to optimize energy. Take advantage and save costs. This includes maximizing feed-in tariffs by intelligently managing energy consumption and timing of storage.
Q: What is AI mode and how does it work?
A: AI mode is a feature that utilizes artificial intelligence algorithms to analyze and learn from a user's electricity consumption data and local electricity price information. It predicts the user's future electricity demand and price trends. Based on these predictions, AI mode automatically adjusts the system's operation strategy to achieve optimal energy utilization efficiency and cost savings. For example, during periods of low electricity prices, AI mode will adjust the system to store electricity in the battery for later use during peak hours, avoiding the need to purchase expensive electricity from the grid. Conversely, during periods of high electricity prices, AI mode will prioritize using the stored energy in the battery to minimize electricity purchases from the grid and reduce costs.
Q: How do I enable Modbus TCP?
A: When the device is connected to a third-party EMS that needs to use ModBus-TCP communication, click "Settings" on the "Device" page through the mySigen app, and set the following parameters on the "All-in-One Settings" screen. 1.ModBus Server Address: Specifies the IP address of a third-party EMS server when the device functions as the Modbus TCP client. 2.ModBus Server Port: Specifies the port for the device to communicate with a thirdparty EMS when the device functions as the Modbus TCP client. 3.ModBus Local (Slave) Address: Specifies the Modbus address of the device when the Modbus protocol is used. You must set different Modbus addresses for devices in parallel mode. 4.ModBus TCP Server Enable: When this parameter is set to , the device functions as the Modbus TCP server and enables connection with a third-party EMS.
Q: How can I set my battery charge from grid in a low tariff?
A: To charge the battery from grid in a low tariff, please find one of the following options: 1. Time of Use (TOU) Mode Go to "Time-based Control" and set the charging time (according to the low tariff). 2. AI mode As your area has agile tariff, you can turn on AI mode and allow system to learn the system performance, the system will able to charge when the tariff is low.
Q: Why does my battery not charge?
A: The battery charge or discharge rate will be due for multiple conditions, including system setting, battery charging rate, cable connections, and other reasons: System settings 1. Battery reaches charge cut-off SOC. 2. Discharging period in TOU mode. 3. AI mode was set: which will operate the system according to the system consumption and the agile tariff. When the tariff is low; the system will determine and use the grid power first; which has resulted the battery does not charge/discharge. 4. Fully fed into grid mode was set: When storage battery is installed, do not set this mode. 5. The remote EMS scheduling was enabled: This setting will allow 3rd party energy company to control your batteries (known as virtual power plant (VPP), as if the customer have not sign the VPP agreement, the battery will not charge or discharge. 6. Max self-consumption mode was set: PV does not generate electricity or PV generates only enough to supply the load. 7. Import limitation was set. Cable connections Abnormal meter installation: When the tariff is negative, it will be more profitable to buy electricity from the grid than PV generation. Please refer to the FAQ (If the meter is installed correctly?) for specific troubleshooting. Battery charging rate The battery electron movement will be affected by the temperature, when the temperature is lower, the movement will charge slower but consume faster; when the battery does not charge, it might be due to the battery temperature; as the battery has heat plate inside the battery structure, therefore, customers may see the battery is charging slow at the beginning; but after a while, the battery charging speed will tend to faster. Other reasons 1. Hybrid inverter without license: Please contact your distributor to purchase a license. 2. Battery fault: Check if there have related alarms on the App.
Q: Why does my PV not generate?
A: PV generation is generally affected by different variables such as system settings, cable connections and environmental conditions: System settings: 1. Negative tariff with AI mode: When the tariff is negative, it will be more profitable to buy electricity from the grid than PV generation. 2. The remote EMS scheduling was enabled: System operating modes can be affected. Use this feature only if required. 3. Export limitation: If "Export limitation" is enabled and the battery has reached the charge cut-off SOC, the load does not work and the PV will not generate power. 4. System fault: Check if there have related alarms on the App Cable connections: 1. Abnormal meter installation: Abnormal meter installation will affect related readings, system may operate abnormally due to incorrect readings. Please refer to the FAQ (If the meter is installed correctly?) for specific troubleshooting. 2. PV board fault or abnormal PV connection: Use a multimeter to measure the positive and negative voltages of the PV to confirm that the voltage values are normal and not reversed. Abnormal PV connection may be checked via "Diagnosis" on "MySigen App". 3. PV voltage too low: If the PV voltage is lower than the start-up voltage of the system, the PV will not generate power. Three-phase: not less than 220V, single-phase: not less than 120V; 4. PV voltage too low: If the voltage of the PV is too high, the device will trigger overvoltage protection and the PV will no longer generate electricity. Three-phase: not higher than 1000V, single-phase: not higher than 600V; Environmental conditions: 1. Weather: such as temperature and weather forecast will degrade the PV generations, and this is irresistible 2. Shading: such as shadows, sunlight orientations and cloud shading on solar panels will affect the PV generation. Sigenergy will temporarily usie of grid power to balance out of the system and using power from the load. (Grid balancing will occur within 5 mins) 3. Consumption: PV generation will be determined by the load consumption including battery storage, as if the battery capacity is full, and your property has set with zero export to the gird, the PV will generate according to the requirements of load consumption.
