6. Operating Instructions

Once installed, the inverter can be configured and operated through its LCD display, LED indicators, and smartphone app.

6.1 Powering On/Off

• To Power On: Ensure all connections are secure. Turn on the DC breaker for the battery, then the AC input breaker (if applicable), and finally the inverter's power switch.
• To Power Off: Turn off the inverter's power switch, then the AC input breaker, and finally the DC breaker for the battery.

6.2 LCD Display and Indicators

The inverter features an HD LCD display and three LED indicators to provide real-time system status and allow for configuration.

6.3 Charging Modes

The inverter supports four distinct charging modes, configurable via the LCD settings:

• Solar Priority: Solar power is prioritized for charging batteries and supplying loads. AC power is used only when solar power is insufficient.
• AC Priority: AC utility power is prioritized for charging batteries and supplying loads. Solar power is used only when AC power is unavailable.
• Solar and AC Mixed Charging: Both solar and AC power are used simultaneously to charge batteries and supply loads, optimizing charging efficiency.
• AC Power Priority: AC power is the primary source for loads, with the inverter only activating when AC power is absent.

6.4 Smartphone App Monitoring

Monitor and control your inverter remotely using the dedicated smartphone application. The app provides real-time data, historical records, and allows for remote configuration of settings.
