4. Setup and Installation

4.1 Unpacking

Before installation, carefully unpack the unit and inspect it for any damage. Ensure all items listed below are included in the package:

• Hybrid Solar Inverter Unit
• User Manual
• Communication Cable (if applicable)

4.2 Mounting the Inverter

Choose a suitable location for mounting the inverter, considering the following:

1. Mount on a solid surface capable of supporting the inverter's weight.
2. Ensure adequate ventilation around the unit to prevent overheating. Maintain at least 20 cm clearance from other objects.
3. Avoid direct sunlight, moisture, and dust.
4. Mount the inverter vertically to allow for proper heat dissipation.

4.3 Wiring Connections

All wiring must be performed by a qualified electrician in accordance with local electrical codes and regulations. Incorrect wiring can cause damage to the unit, personal injury, or fire.

• Battery Connection: Connect the battery bank to the inverter's battery terminals. Ensure correct polarity (+ to + and - to -). The inverter supports 12V or 24V DC input.
• PV Array Connection: Connect the solar panel array to the PV input terminals. Observe the correct polarity and ensure the PV array voltage is within the specified MPPT range (30V - 400Vdc).
• AC Input Connection: Connect the utility grid or generator AC input to the inverter's AC input terminals.
• AC Output Connection: Connect your AC loads to the inverter's AC output terminals.
• Grounding: Ensure the inverter is properly grounded to prevent electrical hazards.

Before making any connections, ensure all power sources (PV, battery, AC input) are disconnected.

5. Operating Instructions

5.1 Initial Power-Up

1. After all wiring is complete and verified, connect the battery breaker.
2. Connect the PV array breaker.
3. Connect the AC input breaker (if using utility/generator).
4. Turn on the inverter's power switch. The LCD display should illuminate, and the unit will begin its self-test sequence.

5.2 LCD Display and Control Buttons

The LCD display provides real-time operational data, status indicators, and fault codes. The four control buttons allow for navigation and parameter adjustments:

• ESC: Exits the current menu or setting without saving changes.
• UP: Navigates upwards through menu options or increases a parameter value.
• DOWN: Navigates downwards through menu options or decreases a parameter value.
• ENTER: Confirms a selection, enters a menu, or saves a parameter change.

5.3 Operating Modes

The inverter supports various operating modes to suit different power management needs. These modes can typically be configured via the LCD display:

• Utility Priority Mode: AC input (utility/generator) is the primary power source. Solar and battery provide backup.
• Solar Priority Mode: Solar power is the primary source. Battery and utility provide backup.
• Battery Priority Mode: Battery power is the primary source. Solar charges the battery, and utility provides backup when battery is low.

5.4 Parameter Settings

The inverter allows users to customize various parameters, such as output voltage, charging current, battery type, and operating mode. Refer to the detailed menu structure in the full manual for specific parameter settings. Use the UP/DOWN buttons to navigate and ENTER to select/confirm.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your OFAPLFKUR Hybrid Solar Inverter. Always disconnect all power sources before performing any maintenance.

• Cleaning: Periodically clean the exterior of the inverter with a dry cloth. Ensure ventilation openings are free from dust and debris.
• Connection Checks: Annually inspect all wiring connections (battery, PV, AC input/output) for tightness and corrosion. Tighten any loose connections.
• Ventilation: Ensure the area around the inverter remains clear to allow for proper airflow and heat dissipation.
• Battery Inspection: If using lead-acid batteries, check electrolyte levels and terminal condition as per battery manufacturer guidelines.
