4. Setup and Installation
Growatt does NOT provide installation support. It is mandatory to contact a certified EPC (Engineering, Procurement & Construction) company to purchase the complete solar kit (panels, wiring, mounting, protection devices) and complete the installation. Improper installation can void the warranty and pose significant safety risks.
4.1 Site Selection
- Choose a location that is well-ventilated and protected from direct sunlight, rain, and snow.
- Ensure adequate clearance around the inverter for proper heat dissipation.
- The mounting surface must be strong enough to support the inverter's weight (approximately 7.4 kg).
4.2 Electrical Connections
All electrical connections (DC input from solar panels, AC output to grid, grounding) must be performed by a qualified electrician following the wiring diagrams provided in the detailed installation guide (typically supplied with the product packaging) and local electrical codes.
- Verify correct polarity for DC connections.
- Ensure all AC connections are securely tightened.
- Proper grounding is essential for safety.
5. Operating Instructions
Once the inverter is professionally installed and all connections are verified, follow these general steps for startup:
- Connect DC Power: Turn on the DC disconnect switch (if present) or connect the solar panel strings to the inverter.
- Connect AC Power: Turn on the AC circuit breaker that connects the inverter to the grid.
- Inverter Startup: The inverter will perform a self-test. Observe the display and status indicators. The 'Normal' indicator should illuminate, and the display will show operational data.
- Monitoring: Use the Growatt Shine App to monitor performance (see Section 6).
The inverter will automatically begin converting solar energy to AC power and feeding it into the grid when conditions are suitable.
6. Monitoring
The Growatt 1000-S features integrated WiFi for remote monitoring of your solar system's performance.
- Download App: Download the 'Growatt Shine App' from your smartphone's app store.

- Connect Inverter: Configure the inverter's WiFi module to connect to your home network. Refer to the specific WiFi module manual for detailed instructions.
- Monitor Data: Once connected, you can view real-time and historical data on energy production, system status, and more directly from your smartphone or computer.
7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your inverter.
- Visual Inspection: Periodically inspect the inverter for any visible damage, loose connections, or signs of corrosion.
- Cleaning: Keep the inverter's ventilation openings clear of dust and debris to ensure proper cooling. Use a soft, dry cloth for cleaning the exterior. Do not use liquids or abrasive cleaners.
- Professional Check: It is recommended to have a qualified technician perform a comprehensive system check annually.
