1. Introduction
This manual provides essential information for the safe and efficient operation of your POWLSOJX Solar Grid Tie Micro Inverter. This device is designed to convert direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which can then be fed into the utility grid. Featuring Maximum Power Point Tracking (MPPT) technology, it optimizes power collection from your solar array.
The POWLSOJX Micro Inverter series includes models T-180W, T-500W, and T-700W, each designed for specific power outputs and solar panel configurations. Please refer to the specifications section for details relevant to your specific model.
2. Safety Instructions
Read all instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Qualified Personnel: Installation and maintenance should only be performed by qualified personnel with knowledge of electrical systems and solar power.
- Ventilation: The grid-tie inverter generates heat during operation. Install it in a well-ventilated, dry, and cool location. In hot climates, consider using a small fan for additional heat dissipation.
- Water Protection: The inverter features an IP65 waterproof streamline design to prevent rainwater erosion. However, ensure all connections are secure and protected from direct water exposure.
- DC Terminal Connections: Use appropriate connectors and ensure secure connections. Poorly connected banana plugs can cause short circuits at the DC terminals, leading to instantaneous voltage surges and potential damage.
- Voltage Range: Ensure the solar panel's Vmp (Maximum Power Voltage) is within the specified MPPT range of the inverter for optimal performance and to prevent damage. Refer to the product specifications for your model's voltage limits.
- Disconnection: Before performing any maintenance or troubleshooting, disconnect the inverter from both the solar panels (DC input) and the utility grid (AC output).
3. Product Overview
The POWLSOJX Solar Grid Tie Micro Inverter is designed for efficient and reliable solar power conversion. Key features include:
- Powerful MPPT Algorithm: Built-in Maximum Power Point Tracking (MPPT) optimizes power collection from solar panels, accurately tracking and locking in the point of maximum output power to significantly increase power generation.
- Reverse Transmission Technology: Achieves up to 99.9% efficiency, transmitting power in the reverse direction in grid-connected output mode. It automatically detects and prioritizes loads in the circuit, improving transmission efficiency.
- Pure Sine Wave Output: Utilizes SPWM (Sine Pulse Width Modulation) to generate a pure sine wave directly. This ensures good waveform, low distortion, and low noise, which is beneficial for sensitive electronic devices and communication equipment.
- Grid-Connected Stacking Mode: Multiple inverters can be stacked and connected in parallel to achieve grid-connected power generation. The system allows for synchronous output once the main monitoring system sends out the main control signal.

4. Setup and Installation
Proper installation is critical for the safety and performance of your micro inverter. Consult a qualified electrician if you are unsure about any steps.
- Mounting Location: Choose a cool, dry, and well-ventilated area, preferably shaded, to mount the inverter. Ensure adequate airflow around the unit to prevent overheating.
- Mounting: Securely mount the inverter to a stable surface using appropriate hardware. Ensure it is mounted vertically or in a way that facilitates heat dissipation.
- DC Input Connection: Connect the DC output cables from your solar panel(s) to the DC input terminals of the micro inverter. Observe correct polarity (+ to + and - to -). Ensure the solar panel's operating voltage (Vmp) is within the inverter's specified DC input range (e.g., 20-50V for most models, but 180W model can only reach a maximum of 30V).
- AC Output Connection: Connect the AC output cable from the micro inverter to your electrical grid. This typically involves connecting to a dedicated circuit breaker in your electrical panel. Ensure all AC connections are secure and meet local electrical codes.
- Grounding: Ensure the inverter is properly grounded according to local electrical regulations.
- Inspection: Before powering on, double-check all connections for tightness, correct polarity, and insulation.
5. Operating Instructions
Once installed and all connections are verified:
- Power On: Turn on the AC circuit breaker connected to the inverter. Then, ensure the solar panels are receiving sufficient sunlight to generate DC power.
- Indicator Lights: The inverter will typically have indicator lights (e.g., green LED) to show its operational status. A steady green light usually indicates normal operation and grid connection. A blinking light might indicate startup, searching for MPPT, or a fault.
- Monitoring: Some models may offer monitoring capabilities to track power generation. Refer to specific product documentation for details on monitoring systems.
- Automatic Operation: The micro inverter is designed to operate automatically, converting solar DC power to AC and feeding it into the grid whenever sufficient sunlight is available. It will automatically shut down if the grid power is lost (anti-islanding protection).
6. Maintenance
The POWLSOJX Micro Inverter requires minimal maintenance to ensure long-term performance.
- Regular Inspection: Periodically inspect the inverter and all connections for any signs of damage, corrosion, or loose wiring.
- Cleaning: Keep the inverter's exterior clean and free from dust and debris. Use a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation openings are not obstructed.
- Environmental Conditions: Ensure the installation environment remains within the recommended temperature and humidity ranges. Address any issues that might lead to excessive heat buildup.
7. Troubleshooting
If you encounter issues with your micro inverter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output / Inverter not starting | No DC input from solar panels; AC grid not connected; Faulty wiring; Insufficient sunlight. | Check solar panel connections and sunlight exposure. Verify AC grid connection and circuit breaker. Inspect all wiring. |
| Inverter shuts down frequently | Overheating; DC input voltage out of range; Grid instability. | Ensure proper ventilation and consider a cooling fan in hot conditions. Verify solar panel voltage is within specifications. Consult utility provider for grid issues. |
| Low power output | Shading on solar panels; Suboptimal DC input voltage; Dirty solar panels. | Clear any shading. Verify solar panel voltage. Clean solar panels. |
| Green light blinking continuously | Normal startup sequence; Searching for MPPT; Minor fault. | Allow time for startup. If persistent, check connections and refer to specific model's fault codes if available. |
| Inverter gets very hot | Insufficient ventilation; High ambient temperature; Overload. | Improve ventilation. Relocate to a cooler spot or add a fan. Ensure total wattage does not exceed inverter capacity. |
If problems persist, contact customer support or a qualified technician.
