Power One Solar Inverter Now Rebranded to ABB

Power One Solar Inverters and ABB Solar Inverters.  Power-One products have been rebranded to ABB. Here you can learn about the full line of solar power inverters by ABB, formerly Power-One.  From micro inverters to central inverters. 

ABB Micro Inverters:

The new ABB MICRO-0.25-I-US AND ABB MICRO-0.3-I-US Micro-Inverters from the line of ABB solar inverters are a superior entry into the exploding Micro Inverter space.  At >96.5% efficiency, the larger 250w and 300w Micro-Inverters pair with the larger solar panels, making them ideal for residential, and even commercial, installations. With Micro-Inverters, the solar panels can be controlled individually and offer the Maximum Power Point Tracking (MPPT) for each panel.  Also, with a Micro-Inverter installation, a low-performing module will not affect the complete system, maximizing performance of the system at all times.  The added flexibility with system design and timing of cost make the Micro-Inverter solution very attractive intoday’s solar market, and the ABB solar inverters line is as good as it gets. The videos below will illustrate the simple installation, along with the monitoring system that can be collected via wireless communication with the PVI-CDD. The data sheet is available below.

ABB PVI-5000 and PVI-6000:

Designed for small commercial PV and residential installations, ABB solar inverters PVI-5000 and PVI-6000 fill a specific area of need in the ABB solar inverters product line that caters to installations which produce between 5kw and 25kw. These inverters have all the usual benefits of an Aurora inverter, like dual inputs for two strings with independent MPPTs, high speed, accurate, MPPT algorithm for live energy tracking and harvesting, in addition to transformerless operation for high efficiency ratings of up to 97%. Wide input range of voltage makes these solar inverters usable for low power installations with lower string size. These outdoor inverters have been designed as completely sealed units that can withstand the harshest weather conditions.

Bonfiglioli solar inverter manual (for reference)

Step 1: Safety Precautions

Before attempting any repairs, ensure that the inverter is disconnected from the power source. Always wear safety gloves and goggles to protect yourself from potential electrical hazards.

Step 2: Visual Inspection

Inspect the Bonfiglioli solar inverter for any visible damage, loose connections, or burnt components. Check the internal cooling fans for blockages or excessive dust accumulation. If any physical damage is observed, consult the manufacturer or a qualified technician for further assistance.

Step 3: Check the Power Supply

Using a multimeter, verify if the inverter is receiving the correct voltage from the power source. Check the circuit breaker and fuses associated with the inverter to ensure they are not tripped or blown. Replace any faulty fuses if necessary.

Step 4: Troubleshooting Common Issues

a. No Output Power: If the inverter is not producing any power, check the DC input voltage from the solar panels. Test the solar panel strings and ensure they are functioning correctly. Verify that the inverter's output settings and configurations are properly set.

b. Fault Indications: If the inverter displays error codes or fault indications, consult the Bonfiglioli manual for a list of possible causes. Test the affected components using a multimeter and replace any defective parts as required.

c. Overheating: Overheating can be caused by insufficient ventilation or malfunctioning cooling fans. Clean or replace the cooling fans if necessary, ensuring they are operating optimally to prevent overheating.

d. Ground Faults: Inspect the grounding connections for any loose or corroded connections. Ensure that the ground fault protection mechanisms are functioning correctly. Re-establish proper grounding if needed.

Step 5: Component Level Repair

If you have identified faulty components, such as capacitors, diodes, or transistors, use a soldering iron and solder to replace them. Ensure you have the correct replacement components as per the manufacturer's specifications.

Step 6: Firmware/Software Updates

Check if there are any available firmware or software updates for the Bonfiglioli solar inverter. Follow the manufacturer's instructions to update the inverter's firmware, which can address software-related issues and enhance overall performance.

Step 7: Testing and Final Checks

After completing the repairs, reconnect the inverter to the power source and perform thorough testing. Ensure the inverter is operating within the expected parameters, including voltage output and efficiency. Monitor the inverter for a sufficient period to ensure that the repairs have resolved the identified issues.

Conclusion:

Repairing Bonfiglioli solar inverters requires careful attention to detail, proper tools, and expertise in electrical systems. By following this comprehensive guide, you should be able to troubleshoot common issues and successfully repair Bonfiglioli
