5. Installation
Follow these steps for proper installation of your grid-tie micro inverter. Refer to the wiring diagram and video for visual guidance.
Installation Steps:
- Mounting: Choose a suitable location for mounting the inverter. Ensure it is a cool, dry, and well-ventilated area, protected from direct sunlight and moisture.
- DC Connection (Step 1 in video): Connect the DC input cables from your solar panels or wind turbine to the DC input terminals on the inverter. Ensure correct polarity (positive to positive, negative to negative). The video demonstrates connecting the DC input first.
- AC Connection (Step 3 in video): Connect the AC output cable from the inverter's AC GRID port to your home's electrical system or directly to the utility grid, following local electrical codes. The video shows plugging in the AC power cord.
- Grounding: Ensure the inverter is properly grounded according to local electrical standards.

Video: This official Marsrock Power video demonstrates the connection process for the GTI1300 inverter, including DC input and AC grid connection, and shows the indicator lights during startup and operation.
6. Operating Instructions
Once installed, operating the inverter is straightforward.
- Power On (Step 2 in video): After ensuring all connections are secure, turn on the inverter using the power switch on the AC side. The red ERROR light will illuminate briefly, then turn off.
- Grid Connection: Plug the AC power cord into the AC GRID port. The blue AC GRID light will turn on.
- Startup Sequence: The green RUN light will begin flashing, indicating the inverter is performing its self-test and synchronizing with the grid. This process may take a few seconds.
- Normal Operation: Once synchronized, the green RUN light will become solid, indicating that the inverter is actively converting DC power to AC and feeding it into the grid. The video shows the green light becoming solid as power generation begins.
- Monitoring: You can monitor the power output using an external power meter (not included) connected to your system, as shown in the wiring diagram and video.

9. Troubleshooting
If you encounter issues with your inverter, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not power on (no lights) | No DC input power; Blown DC fuse; Faulty power switch. | Check DC input connections and voltage; Replace DC fuses; Ensure power switch is ON. |
| Red ERROR light is on | DC input voltage out of range; Over-temperature; Internal fault. | Verify DC input voltage (20-50V); Ensure adequate ventilation; Contact support if issue persists. |
| Green RUN light flashing, not solid | Inverter is synchronizing with grid; Grid voltage/frequency unstable. | Wait for synchronization (up to 30 seconds); Check grid stability; Ensure AC connection is secure. |
| Low power output | Insufficient DC input power; Shading on solar panels; Suboptimal MPPT operation. | Check solar panel output; Clear any shading; Ensure panels are clean. |
| Inverter overheats and shuts down | Poor ventilation; Blocked fan; Excessive ambient temperature. | Ensure clear airflow around inverter; Clean fan and vents; Relocate to a cooler area if necessary. |
If troubleshooting steps do not resolve the issue, contact customer support for further assistance.
