4.1 Mounting the Inverter

• Choose a dry, well-ventilated area, away from direct sunlight and heat sources.
• Mount the inverter vertically on a sturdy surface.
• Ensure sufficient clearance around the unit for proper airflow (at least 20 cm on all sides).

4.2 Wiring Connections

1. Battery Connection: Connect the battery bank to the "Battery positive" and "Battery negative" terminals. Ensure correct polarity. Use appropriate gauge wiring for the current draw.
2. Solar Panel Connection: Connect the solar array to the PV input terminals. Observe correct polarity and ensure the PV voltage is within the inverter's specified range.
3. AC Input Connection: Connect the utility grid or generator AC supply to the "AC input" terminals.
4. AC Output Connection: Connect your AC loads (e.g., household appliances) to the "AC output" terminals.
5. Grounding: Connect the "Safety (earth) ground" terminal to a reliable earth ground.

Note: All wiring should comply with local electrical codes and regulations. Consult a qualified electrician if you are unsure about any part of the installation process.

5. Operating Instructions

5.1 Powering On/Off

• To Power On: After all connections are secure, switch on the battery breaker (if applicable), then the solar array breaker (if applicable), and finally the AC input breaker. Press the "ON/OFF" button on the inverter.
• To Power Off: First, disconnect all AC loads. Then, switch off the AC input breaker, followed by the solar array breaker, and finally the battery breaker. Press and hold the "ON/OFF" button on the inverter until it shuts down.

5.2 LCD Display and Settings

The LCD display provides real-time information about the inverter's operation. Use the function buttons to navigate through the display screens and adjust settings. Refer to Section 3.2 for a detailed explanation of the LCD icons and indicators.

Key configurable settings typically include:

• AC input voltage range (e.g., for PC or home appliances).
• Charger priority (Solar first, Utility first, Solar and Utility).
• Output source priority (Utility first, Solar first, SBU - Solar, Battery, Utility).
• Battery type and charging parameters.
• Alarm settings.

Consult the detailed settings menu in the full product manual for specific parameter adjustments.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your RESKIU Hybrid Solar Inverter.
