Power-One is an Italy-based company that manufactures a range of power conversion and management products, and is well-known in the solar PV industry for its quality solar inverters for residential and commercial solar applications–especially its Aurora inverter line. The company was established in 1973, and began producing components for renewable energy systems in 2006. The Power-One solar catalogue offers a range of transformerless inverters and monitoring equipment for solar power systems.

The importance of choosing the right inverter
An inverter is essentially the ‘brain’ of any solar power system. Inverters convert the DC electricity produced by a system’s solar panels into grid- and appliance-compatible AC electricity. Inverters tend to have shorter lifetimes and warranties than solar panels–5 to 10 years as opposed to 25 or 30–and also tend to be the most expensive part of a system. Generally speaking, looking for a high-end inverter from a reputable manufacturer is arguably even more important than focusing on the quality of the system’s solar panel array. Indeed, a strategy of many Solar Choice customers is to opt for solar PV systems with mid-quality panels but high-quality inverters, to safeguard possible malfunction.
