5. Operating

5.1 LCD Display and Buttons

The inverter features an intuitive LCD display and function buttons for monitoring operating status, input/output power information, and setting various parameters such as battery charging current and energy priority.

5.2 Operating Modes

The hybrid solar inverter offers flexible operating modes to suit different needs and scenarios, allowing you to optimize electricity costs and ensure continuous power supply:

• Solar First: Prioritizes solar power for loads and battery charging.
• Solar and Utility: Uses solar power primarily, with utility grid as a backup.
• Only Solar: Operates solely on solar power.
• Mains First: Prioritizes utility grid, with solar/battery as backup.
• SBU Priority: Solar, Battery, then Utility priority.

Figure 5.1: The inverter supports three safe charging modes (Solar First, Solar and Utility, Only Solar) and three output modes (Mains First, Solar First, SBU priority) for versatile power management.

5.3 Battery-Less Operation

This inverter can operate without a connected battery. In this mode, it uses PV power directly to run loads, provided the PV input voltage exceeds 120VDC.
