• Enhanced Energy Stability: Provides reliable power through Uninterruptible Power Supply (UPS) functionality and multiple output modes, reducing reliance on traditional energy sources and leading to significant cost savings.
• Segmented Charging/Discharging: Features three output modes (mains priority, battery priority, PV priority) and four charging modes (Only Solar, Mains Priority, Solar Priority, and Mains and Solar hybrid charging). This allows for flexible time-period settings for mains charging/discharging to optimize energy use based on local grid conditions.

3. Setup

Proper installation is crucial for the safe and efficient operation of your ECO-WORTHY Solar Hybrid Inverter Charger. It is recommended that installation be performed by a qualified electrician or solar professional.

3.1 Unpacking and Inspection

• Carefully unpack the inverter and all accessories.
• Inspect the unit for any physical damage that may have occurred during transit. Report any damage to your supplier immediately.
• Verify that all components listed in the packing list are present.

3.2 Mounting the Inverter

• Choose a suitable mounting location that is dry, well-ventilated, and protected from direct sunlight, rain, and dust. Ensure adequate clearance around the unit for proper airflow and cooling.
• Mount the inverter vertically on a sturdy surface using appropriate fasteners.

3.3 Wiring Connections

All wiring must comply with local and national electrical codes. Ensure all power sources are disconnected before making any electrical connections.

• Battery Connection: Connect the 48V battery bank to the inverter's battery terminals. Ensure correct polarity (positive to positive, negative to negative).
• PV Input Connection: Connect your solar panel array to the PV input terminals. Observe the correct voltage and current limits as specified in the technical specifications.
• AC Input/Output Connection: Connect the utility grid (AC input) and your household loads (AC output) to the respective terminals. For parallel operation, follow the specific wiring diagrams provided in the full user manual.
• Grounding: Ensure the inverter is properly grounded to prevent electrical hazards.
• Communication Ports: Connect any necessary communication cables (e.g., for parallel operation, remote monitoring, or external BMS) to the designated ports (RS485, USB, Dry Contact).

4. Operating Modes

The ECO-WORTHY inverter offers flexible operating modes to suit various energy management needs.

4.1 Output Priority Modes

• Mains Priority: The inverter primarily uses utility grid power to supply loads. Battery power is used only when the grid is unavailable.
• Battery Priority: The inverter prioritizes drawing power from the battery bank. Utility grid power is used only when battery voltage is low.
• PV Priority: Solar power is prioritized to supply loads and charge batteries. Utility grid power is used as a backup when solar power is insufficient.

4.2 Charging Modes

• Only Solar: Batteries are charged exclusively by solar power.
• Mains Priority: Utility grid power is the primary source for battery charging. Solar power charges only when the grid is unavailable.
• Solar Priority: Solar power is the primary source for battery charging. Utility grid power is used as a supplement only when solar power is insufficient.
• Mains and Solar Hybrid Charging: Both utility grid and solar power are used simultaneously to charge batteries, providing robust charging capabilities.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter.

• Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure ventilation openings are free from dust and debris to maintain proper cooling.
• Connections Check: Annually inspect all electrical connections (battery, PV, AC input/output) for tightness and signs of corrosion. Loose connections can lead to overheating and poor performance.
• Battery Health: Monitor your battery bank's health according to the battery manufacturer's guidelines. Ensure proper charging and discharging cycles.
• Environmental Conditions: Regularly check that the inverter's operating environment remains within the recommended temperature and humidity ranges.
