When comparing the warranty periods of microinverters and string inverters, microinverters generally offer longer warranty coverage. Here’s a breakdown of their typical warranty periods and what they cover:
Microinverters
- Warranty Period: Microinverters typically come with a 25-year warranty. This lengthy warranty reflects the manufacturer’s confidence in the product’s durability and performance.
- Coverage: Microinverters cover manufacturing defects and performance issues. However, they do not cover environmental damage, improper installation, or unauthorized modifications.
- Examples: Enphase IQ series microinverters are a notable example, with a standard 25-year parts warranty.
String Inverters
- Warranty Period: String inverters usually have a shorter warranty period, ranging from 10 to 12 years.
- Coverage: Similar to microinverters, string inverter warranties typically cover manufacturing defects but may not include labor or shipping costs unless specified by the manufacturer.
- Examples: Companies like SMA and SolarEdge offer standard warranty periods for string inverters around 10-12 years, though SolarEdge’s optimized string inverters may offer longer coverage for power optimizers.
In summary, microinverters have a significantly longer warranty period than string inverters, providing extended protection against manufacturing defects and ensuring long-term performance of the solar system.
