String inverters are the most common type of inverter used in the UK, Europe, Australia, & Asia, and are growing in popularity in the US, where micro inverters are very popular. These inverters are connected to a string of solar panels linked together in series. This review focuses on common 'string' solar inverters, the most popular type of solar inverter. Many different inverters are available for solar and energy storage systems, but here we list the four most common types used for rooftop solar. This will have a much greater financial impact due to system downtime. Most of the 'value' brands also offer 10-year warranties, but some will only repair a faulty unit if it is shipped to them (at the owner's cost) and returned, which can take weeks and sometimes months. Fronius, SMA, Fimer, Goodwe, Sungrow and Huawei are all available with 10-year warranties, while SolarEdge offers a 12-year manufacturer’s warranty as standard. With this in mind, it is worthwhile to pay the additional cost for a quality inverter brand that has been in good business standing for at least five years.įronius and SMA have ranked on top of the list for many years due to the low failure rates and great service, as they usually ship replacement units in 3-5 business days. However, unlike a faulty inverter, degradation of solar panels will generally not result in a complete system shutdown that being said, we recommend using only reputable solar panel brands from a reliable installer. Solar panels can also develop problems or suffer from excessive degradation over time, resulting in poor performance. If direct sunlight cannot be avoided, a protective sun cover will help prolong the life of the inverter. Most importantly, locations exposed to the hot afternoon sun should always be avoided. The life of a solar inverter will be significantly increased by locating it inside a garage, under a carport and out of direct sunlight. However, like any electrical equipment, solar inverters should be installed in a protected or shaded location to avoid extreme weather and large variations in temperature, which can reduce performance and lifespan. Almost all solar inverters are fully weather-rated and can be safely installed outside.
