Connection Diagrams for Operating Modes

The UDM-GS Microinverter supports six working modes, allowing flexible configuration with PV modules, batteries, or both. These modes include options for Zero Export (consuming generated electricity internally) and On-Grid (exporting surplus electricity to the grid).

Obrázek 6: Přesview of the six working modes: Storage Mode (Zero Export, On-Grid), PV Mode (Zero Export, On-Grid), and Battery Mode (Zero Export, On-Grid). This diagram illustrates the wide applicability of the inverter for various power generation and storage setups.

Mode 1: Storage Zero Export Mode

Figure 7: Connection for Storage Zero Export Mode, utilizing a 36V/48V battery and PV modules (VOC<60VDC). The system prioritizes internal consumption, preventing electricity export to the grid. Battery connection cables and AC plug cable need to be purchased separately.

Mode 2: Storage On-Grid Mode

Figure 8: Connection for Storage On-Grid Mode, integrating a 36V/48V battery and PV modules (VOC<60VDC) with the home grid. This mode allows for both internal consumption and export of surplus power. Battery connection cables and AC plug cable need to be purchased separately.

Mode 3: PV Zero Export Mode

Figure 9: Connection for PV Zero Export Mode, using two PV panels (VOC<60VDC). Generated power is primarily used for internal loads, with no export to the grid. The AC plug cable needs to be purchased separately.

Mode 4: PV On-Grid Mode

Figure 10: Connection for PV On-Grid Mode, using two PV panels (VOC<60VDC) connected to the home grid. This setup allows for both powering home appliances and exporting excess solar energy to the grid. The AC plug cable needs to be purchased separately.

Mode 5: Battery Zero Export Mode

Figure 11: Connection for Battery Zero Export Mode, utilizing a 36V/48V battery. Power from the battery is used for internal consumption only, with no export to the grid. Battery connection cables and AC plug cable need to be purchased separately.

Mode 6: Battery On-Grid Mode

Figure 12: Connection for Battery On-Grid Mode, using a 36V/48V battery connected to the home grid. This mode allows the battery to power home appliances and potentially export excess power to the grid. Battery connection cables and AC plug cable need to be purchased separately.

3. Obsluha měniče

Monitorování a kontrola

The inverter features a built-in WiFi module for remote monitoring and control via a dedicated mobile application. This allows users to view real-time operational data and adjust settings.

• Úprava nastavení: Configure operating parameters and modes through the app interface.

MPPT Functionality

The integrated MPPT (Maximum Power Point Tracking) technology ensures that the solar panels operate at their peak power output, maximizing energy yield throughout the day, even under varying light conditions.

4. Údržba

To ensure optimal performance and longevity of your POWLSOJX Micro Grid-Tie Inverter, regular maintenance is recommended:

• Čištění: Periodically clean the exterior of the inverter, especially the cooling fins, to prevent dust and debris buildup that could hinder heat dissipation. Use a soft, dry cloth.
• Inspekce: Regularly check all electrical connections for tightness and signs of corrosion or damage. Ensure cables are not frayed or exposed.
• Ochrana životního prostředí: The inverter has an IP65 waterproof rating, making it suitable for outdoor installation. However, avoid direct exposure to extreme weather conditions if possible, and ensure proper ventilation around the unit.
• Aktualizace firmwaru: Check for any available firmware updates via the mobile application to ensure the inverter operates with the latest features and optimizations.

5. Řešení problémů

If you encounter issues with your POWLSOJX Micro Grid-Tie Inverter, consider the following general troubleshooting steps:

• Žádný výkon: Verify that DC input from PV panels or battery is within the specified voltage range. Check all AC and DC connections for proper seating and continuity. Ensure the AC grid connection is active.
• Nízký výstupní výkon: Check for shading on PV panels. Ensure PV panels are clean. Verify that the inverter's operating mode is correctly configured for your setup.
• Kontrolky: Consult the manual for the meaning of different indicator light patterns, which can signal specific operational states or faults.
