5. Nastavení a instalace
Follow these steps for proper installation and connection of your micro inverter.
5.1 Montáž střídače
The inverter should be mounted in a well-ventilated area, preferably out of direct sunlight, using the provided mounting brackets and screws. Ensure sufficient clearance around the unit for proper heat dissipation.
5.2 Elektrické připojení
Refer to the following video for a visual guide on connecting the micro inverter to solar panels and the grid.
Video: Demonstrates the unboxing and connection process for a similar micro inverter model, including DC input from PV modules and AC output to the grid.
- Připojení DC vstupu: Connect your solar PV modules or battery to the DC input terminals of the inverter. Ensure correct polarity (positive to positive, negative to negative). The inverter supports 20V-60V PV input and 36V/48V batteries.
- Připojení výstupu střídavého proudu: Connect the AC output cable from the inverter to your home's electrical grid. This connection should be performed by a qualified electrician to ensure compliance with local electrical codes.
- Limiter Connection (Optional): If using the external limiter function for zero export, connect the limiter sensor as per the instructions provided with the limiter unit.
For detailed wiring diagrams and safety precautions, consult the included specification sheet and consider professional installation.
6. Provozní režimy
The UDM-GS Micro Inverter supports six distinct operating modes, allowing for flexible power generation and consumption management. These modes can be configured via the mobile application.

Obrázek: Overview of the six available operating modes for the UDM-GS Micro Inverter.
- Storage Zero Export Mode: Connects batteries and PV modules, enabling zero export to the grid.
- Storage On-Grid Mode: Connects batteries and PV modules, disabling zero export to the grid.
- PV Zero Export Mode: Connects PV modules only, enabling zero export to the grid.
- PV On-Grid Mode: Connects PV modules only, disabling zero export to the grid.
- Battery Zero Export Mode: Connects batteries only, enabling zero export to the grid.
- Battery On-Grid Mode: Connects batteries only, disabling zero export to the grid.
The built-in Power Limitation and Zero Export function allows the inverter to generate electricity according to the power consumption of the load, ensuring generated electricity is primarily used internally without outputting power to the external grid when zero export is enabled.
7. Operation & Monitoring
The micro inverter features a built-in WiFi module for remote monitoring and control via a dedicated mobile application. This allows you to track performance and adjust settings from your smartphone or tablet.
