Growatt ARK ja XH - miten myyn verkkoon?

[lmfmis]

Juuri sain asennettua


Miten shinephonea voi komentaa että purkaa akut verkkoon korkean pörssisähkön aikana? Ei oikein avaudu...

Tuolta device, TOU settings, salasana growattYYYYMMDD ja grid first.

Tienaamaan

 

[varikonniemi]

siis pystyykö tuolla myymään akkuihin varastoitua sähköä? Googlen tekoäly sanoi ettei pysty.

 

[korsteeni]

kerro nyt ihmeessä onnistuuko myynti ko laitteistolla pattereista verkkoon?

tässä on grok käsitys kuluttajalaitteista jotka pystyy myymään akusta verkkoon:

• Sungrow SH-RS Series (3-Phase Hybrid Inverter)
  • Main Utility Grid Export Capability: Yes, the Sungrow SH-RS series is designed to export energy to the main utility grid. It supports grid-tied operation with configurable export modes, including zero-export and limited-export settings, and can use TOU schedules to discharge battery energy to the grid during peak pricing periods, even without solar input. Reviews indicate it can manage battery discharge to the grid independently of solar generation, such as at night, when programmed to optimize for high electricity rates.
    
    
    
  • Evidence: Clean Energy Reviews highlights its ability to export excess energy to the grid and its TOU settings for battery discharge optimization, which implies battery-to-grid export to the main utility grid. The inverter complies with grid standards (e.g., IEEE 1547), ensuring proper synchronization with the utility grid.
  • Local Grid Consideration: The SH-RS also supports a backup mode for local loads during outages, supplying power to a dedicated backup circuit (not the main utility grid). However, its grid-tied mode is explicitly designed for utility grid interaction, and battery discharge can be directed to the main grid when configured appropriately.
  • Note: Local utility regulations must permit battery-to-grid export, and the inverter requires a current transformer (CT) or smart meter at the grid connection point to monitor and control export. Users should confirm with Sungrow or their installer to ensure the firmware supports battery-only export to the main grid.
• Deye Sun 8K to 16K Hybrid Inverters
  • Main Utility Grid Export Capability: Yes, Deye hybrid inverters (branded as Sol-Ark in some regions) are capable of exporting battery-stored energy to the main utility grid. They support grid-tied operation with TOU settings, allowing users to schedule battery discharge to the grid during peak tariff periods, even when solar panels are not generating power. The inverters feature dual AC inputs (grid and generator) and can prioritize battery discharge to the utility grid over local loads when configured.
    
    
    
    
    
    
    
  • Evidence: Clean Energy Reviews notes that Deye inverters can operate in grid-tie mode, exporting excess energy to the utility grid, and their TOU functionality supports battery discharge scheduling. Product specifications confirm compliance with grid interconnection standards, enabling export to the main utility grid.
  • Local Grid Consideration: Deye inverters can also supply a local backup circuit during outages (off-grid mode), but this is separate from their grid-tied export functionality. The grid-tie mode ensures that battery energy can be sent to the main utility grid when the grid is active, not just to a local circuit connected to the inverter’s output.
  • Note: Exporting battery energy to the main grid requires proper configuration (e.g., enabling grid-tie mode and setting TOU schedules) and utility approval. Some regions may restrict battery-to-grid export, so verification with the utility and installer is necessary.
• EcoFlow PowerOcean (Single-Phase and Three-Phase)
  • Main Utility Grid Export Capability: Yes, the EcoFlow PowerOcean is designed to export energy to the main utility grid, including battery-stored energy, under schemes like the Smart Export Guarantee. Its smart energy management system supports TOU settings, allowing battery discharge to the grid during peak pricing periods without solar input (e.g., at night). EcoFlow’s documentation explicitly mentions selling surplus electricity to the utility grid, which includes battery energy when configured.
    
    
    
  • Evidence: EcoFlow’s product page and related reviews emphasize its grid interaction capabilities, including exporting surplus energy to the utility grid under buy-back programs. The inverter’s ability to discharge battery energy during peak rate periods suggests it can export to the main grid without solar generation.
  • Local Grid Consideration: The PowerOcean can also power a local backup circuit during outages, but its grid-tied mode is specifically designed for interaction with the main utility grid. The system uses a smart meter or CT to monitor grid flow, ensuring accurate export to the utility grid rather than just a local circuit.
  • Note: Grid export from the battery requires compatible utility policies and proper system setup. Users should confirm with EcoFlow or their installer that the inverter is configured for battery-to-grid export to the main utility grid.
• Tesla Powerwall 3
  • Main Utility Grid Export Capability: Yes, the Tesla Powerwall 3, with its integrated hybrid inverter, can export battery-stored energy to the main utility grid. It supports TOU optimization, allowing users to discharge battery energy to the grid during peak pricing periods, even when solar panels are not producing (e.g., at night). Tesla’s system is designed for net metering and feed-in tariff programs, enabling battery energy export to the utility grid.
    
    
    
  • Evidence: Tesla’s product specifications and discussions on X indicate that the Powerwall 3 can export excess energy, including from the battery, to the utility grid. Its energy management system prioritizes self-consumption but can be configured to export battery energy to the main grid under TOU settings.
  • Local Grid Consideration: The Powerwall 3 can supply a local backup circuit during outages, powering essential loads through its inverter output. However, its grid-tied mode is designed for main utility grid interaction, and battery discharge can be directed to the utility grid when the grid is active, not just to a local circuit.
  • Note: Utility regulations and Tesla’s app settings (e.g., enabling grid export) are critical. Some regions may limit battery-to-grid export, and users should verify with Tesla or their utility provider to ensure compliance.
