• Повезивање батерије: Connect the battery bank to the 'BATTERY POS' and 'BATTERY NEG' terminals. Ensure correct polarity.
• АЦ улазна веза: Connect the utility grid or generator AC supply to the 'AC IN' terminal.
• Прикључак на излаз наизменичне струје: Connect your loads (appliances, computers, etc.) to the 'AC OUT' terminal.
• Прикључак за ПВ улаз: Connect your solar panel array to the 'PV IN' terminals. Observe correct polarity and voltagе лимитс.
• Комуникациони портови: Use the RS232 or USB ports for monitoring and configuration with compatible software.

5. Радни режими

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.
• Режим приоритета батерије: The inverter uses battery power as the primary source. Utility or solar power is used to charge batteries or when battery voltagе је низак.
• Нема режима батерије: Certain models can operate without a battery, directly converting solar PV power to AC for loads, provided the PV voltagе је изнад 250 В.

КСНУМКС. Решавање проблема

This section provides solutions to common issues you may encounter with your inverter. For problems not listed here, please contact customer support.

• Inverter not turning on: Check battery connections, ensure battery voltage is within operating range, verify AC input connection if applicable, and check the input breaker.
• No AC output: Check for overload conditions, ensure the inverter is not in fault mode, verify AC output wiring, and check if the utility grid is present if in utility priority mode.
• Батерија се не пуни: Verify solar panel connections and voltage, check AC input if AC charging is enabled, ensure charge settings are correct on the display.
• Аларм за преоптерећење: Reduce the connected load. The inverter will automatically restart after a cool-down period if the overload is removed.
