Solar Inverters: Extending Lifespan, Types & Maintenance Tips
Solar inverter technology is crucial for converting DC power from solar panels into usable AC power. Two main types exist: string inverters and microinverters. Proper maintenance can extend their lifespan, with some warranties reaching 25 years.
String inverters, with a typical lifespan of 10-15 years, are prone to the 'Christmas light' effect. This occurs when one underperforming panel limits the production of others connected in series. However, some string inverters come with bypass diodes to mitigate this issue. They usually have standard warranties ranging from 5-10 years, extendable to 20 years.
Microinverters, on the other hand, offer longer lifespans, often lasting 20-25 years, with matching warranties. Hoymiles and APSystems currently provide microinverters with a 25-year warranty on balcony power systems, covering the entire system. Growatt microinverters typically have a 10-year warranty.
Both microinverters and DC optimizers are beneficial for roofs with shading conditions or sub-optimal orientation. They can help maximize energy production in such situations. However, 80% of solar array failures occur at the inverter level due to grid faults, MLPE faults, or improper installation.
Inverter maintenance, including regular inspections and professional check-ups every five years, can significantly extend their lifespan. String inverters and microinverters each have their advantages and disadvantages, with warranties ranging from 5-25 years. Understanding these differences can help in choosing the right inverter for a solar power system.
