Micro Inverters

A solar PV system microinverter is a device that plays a crucial role in converting direct current (DC) electricity generated by individual solar panels into alternating current (AC) electricity, which is the form of electricity used in homes and businesses. Unlike traditional string inverters that are connected to multiple solar panels, each solar panel equipped with a microinverter operates independently.

In summary, a solar PV system microinverter improves the efficiency and reliability of a solar installation by converting DC electricity to AC at the individual panel level, offering better performance in varying conditions and simplifying monitoring and maintenance.

Here’s what to look for during a micro inverter inspection:

1. Physical Condition:

   • Check for signs of physical damage, corrosion, or exposure to harsh weather conditions.

   • Ensure that the micro inverters are securely mounted and properly sealed against environmental elements.

2. Electrical Connections:

   • Examine electrical connections for tightness and signs of overheating.

   • Verify that all cables and connectors are in good condition, without any visible wear or damage.

3. Cooling Mechanism:

   • Inspect the cooling mechanisms, such as heat sinks or fans, to ensure they are clean and functioning correctly.

   • Overheating can impact the efficiency of micro inverters, so proper cooling is crucial.

4. Monitoring System:

   • Check the monitoring system for real-time data on individual micro inverter performance.

   • Look for any anomalies or discrepancies in output that may indicate a malfunctioning unit.

5. Shading and Ventilation:

   • Ensure that micro inverters are installed in areas with proper ventilation to prevent overheating.

   • Assess whether shading from nearby structures or vegetation affects the micro inverters’ exposure to sunlight.

6. Software and Firmware Updates:

   • Verify that the micro inverter’s software and firmware are up-to-date.

   • Check for compatibility with the overall solar PV system and any monitoring platforms in use.

7. Manufacturer's Guidelines:

   • Refer to the manufacturer’s guidelines and specifications to ensure that the micro inverters are installed and operating according to recommendations.

   • Follow any maintenance procedures outlined by the manufacturer.

8. Safety Features:

   • Confirm that safety features, such as rapid shutdown capabilities, are functioning correctly.

   • Ensure compliance with local electrical codes and safety standards.

Our dedicated team understands the unique needs of micro inverter setups, and that’s why we give them an extra dose of attention. We go above and beyond to verify the performance of each micro inverter, ensuring they operate at their peak efficiency. Your micro inverter system deserves the royal treatment, and we’re here to make sure it gets just that.

Circuit Breaker Testing

This post expands on the seventh item in our Solar Panel System Check-Up Guide: PV Circuit Breaker Operation.

As part of all of our solar inspections we take a look at your PV circuit breakers making sure they’re doing their part to keep things safe and efficient.

What is a Circuit Breaker?

If a fuse is the easygoing buddy in electrical circuits, then a circuit breaker, called a “CB” by the pros, is like the superhero version – a real champ! The cool thing about CBs is that they’re resettable. Fuses just blow; circuit breakers have an impressive long life, performing hundreds and thousands of operations. Of course it comes with a bit more cost, but you get what you pay for! Also, circuit breakers are the go-to for handling those higher currents. Super handy, right? 😊

Circuit breaker testing is like giving your electrical system a health check. We evaluate each switching component's performance and the tripping system's overall effectiveness. Basically, we analyze how much current the trip coil consumes while the breaker is doing its thing. This helps us spot any mechanical or electrical issues that could mess with the breaker's function and safety.

Now, let's talk about the fun part – the types of tests we perform:

1. Connection Tests: We make sure the breaker has a solid electrical connection and isn't overheating.

2. Overload Tripping Tests: We crank it up to 300% of the breaker rating to see if it opens automatically. Talk about putting it to the test!

3. Contact Resistance Tests: We measure the resistance across each breaker pole to check for any unusual wear and tear.

4. Instantaneous Magnetic Tripping Tests: This ensures that the magnetic feature is on point and will trip the breaker when needed.

How often should you test your circuit breakers?
We recommend a full inspection every one to three years, with an annual check on each breaker’s operation. Depending on your system’s age, you might want to test more often to stay on top of things.

And guess what? Solar Specialty Group has got the tools and expertise to make it all happen. We offer dependable circuit breaker testing solutions. We regularly check for overloads and electricity flow, visually inspect for damage, and if you sense heat or smell burning, hit that main power switch pronto.
