5. Иштөө режимдери
The inverter supports various operating modes, which can be configured via the LCD display. These modes determine the power source priority (utility, solar, or battery) for supplying power to the loads and charging the batteries.

Figure 5.1: Display illustrations showing four operating modes: 1. With battery, solar and AC available. 2. With battery, solar and AC not available. 3. Without battery, solar available. 4. Without battery, AC available. This image also shows a 'Pure Sine Wave 50/60 Hz Auto Detection' graphic.
- Utility Priority Mode: The inverter primarily uses utility power to supply loads and charge batteries. Solar power is used when utility power is unavailable or insufficient.
- Solar Priority Mode: Solar power is the primary source for loads and battery charging. Utility power is used only when solar power is insufficient or unavailable.
- Батареянын артыкчылыктуу режими: The inverter uses battery power as the primary source. Utility or solar power is used to charge batteries or when battery voltage аз.
- Батарея режими жок: Certain models can operate without a battery, directly converting solar PV power to AC for loads, provided the PV voltage 250V жогору.
