4. Installation

Proper installation is crucial for the performance and safety of your hybrid solar inverter. Always consult a qualified electrician for installation to ensure compliance with all local and national electrical codes.

Wiring Diagram and Recommendations:

Figure 4.1: This diagram illustrates a typical wiring setup for the hybrid solar inverter, including connections for photovoltaic (PV) modules, batteries, AC input (utility/generator), and AC output to household loads.

• PV Connection: Max. PV array open circuit voltage: 450Vdc. Max. PV array power: 6500W. Suggested wire: 10 AWG/6mm². It is recommended to connect solar modules in series.
• Battery Connection: For 48V lead-acid/lithium battery systems. Recommended wire size: 2 AWG Cable/25mm². Recommended Fuse: 150A.
• AC Input: For 230VAC input. Maximum AC input voltage: 300VAC. Maximum AC charging current: 160A. Suggested cable: 10AWG/6mm². Recommended switch: 63A.
• AC Output: For 220V/230V output. Rated output current: 44.3Amp. Suggested cable: 10AWG/6mm². Recommended switch: 63A.
• Important: The inverter's output is 230V. For 110V/120V appliances, a separate converter (not included) is required to step down the voltage.

5. Operation

The inverter offers flexible operation modes to suit various energy needs. The LCD display and function buttons allow for easy configuration and monitoring.

Charging Modes:

The inverter supports four charging modes:

• Solar Priority: Solar power is the primary source for charging batteries and powering loads. Utility power is used only when solar power is insufficient.
• Utility Priority: Utility power is the primary source for charging batteries and powering loads. Solar power is used only when utility power is unavailable.
• Solar and Utility Only: Both solar and utility power are used to charge batteries and power loads.
• Battery & Solar: Prioritizes battery power, supplemented by solar.

Output Modes:

The inverter provides three output modes:

• Solar Priority: Loads are primarily powered by solar energy.
• Utility Priority: Loads are primarily powered by utility (grid) power.
• SBU Mode (Solar-Battery-Utility): Loads are powered first by solar, then by battery, and finally by utility power as a last resort.

Wi-Fi Monitoring:

The inverter can be monitored remotely using a Wi-Fi module (included) and a compatible mobile application. This allows users to view real-time data and adjust settings from their smartphone.

6. Maintenance

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

• Keep the inverter clean and free from dust. Use a dry cloth for cleaning.
• Ensure adequate airflow around the unit. Do not block ventilation openings.
• Periodically check all connections for tightness and signs of corrosion.
• Monitor the LCD display for any error codes or warnings.
• The intelligent variable speed fan helps dissipate heat efficiently, contributing to the system's lifespan.
