4.2 Wiring Instructions

Proper wiring is crucial for safe and efficient operation. Ensure all connections are secure and follow local electrical codes. This inverter outputs 220V AC and does not support 110V. Ground and Neutral are not connected together internally.

• Connect the Ground wire to the Ground terminal.
• Connect Hot Line 1 to the L terminal.
• Connect Hot Line 2 to the N terminal.
• NOTE: Do not connect AC input Neutral or Load Neutral to the inverter.
• Battery cable size: 2AWG. Torque value: 2-3 Nm.

5. Operating Modes and Settings

The inverter offers flexible configuration options via its LCD display to optimize power flow based on your specific needs.

5.1 Charger Source Priority

This setting determines the preferred source for charging the battery.

• Solar First: Solar energy is the primary charging source. Utility power charges the battery only when solar energy is unavailable.
• Utility First: Utility power is the primary charging source. Solar energy charges the battery only when utility power is unavailable.
• Solar and Utility: Both solar energy and utility power will charge the battery simultaneously.
• Only Solar: Only solar energy will charge the battery, regardless of utility power availability.

5.2 Output Source Priority

This setting determines the preferred source for powering the connected loads.

• Solar First (PV Priority): Solar power is the primary source for loads.
• Utility First (Default): Utility power is the primary source for loads.
• SBU Priority: Solar power loads first, then battery, and finally utility power.

6. Maintenance

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

• Cleaning: Periodically clean the inverter's exterior with a dry cloth to remove dust and debris. Ensure ventilation openings are clear and unobstructed.
• Connection Check: Annually inspect all electrical connections (PV, battery, AC input/output) for tightness and signs of corrosion. Re-tighten if necessary.
• Battery Inspection: For lead-acid batteries, check electrolyte levels and terminal cleanliness as per battery manufacturer guidelines. For lithium batteries, monitor their health via the inverter's display or a dedicated BMS.
• Environmental Check: Ensure the installation environment remains within specified temperature and humidity ranges. Protect the inverter from direct sunlight, rain, and excessive dust.
• Firmware Updates: If remote monitoring is enabled, check for available firmware updates from the manufacturer to ensure optimal performance and access to new features.
