SMA – Inverter

Description

SMA are a highly respected inverter manufacturer with German heritage and headquarters. The previously German manufactured product was widely regarded as the best inverter on the market but since SMA moved manufacturing to China the brand has lost its elite position here in Australia with Fronius now filling that spot.

Are SMA good solar inverters?

Yes. SMA inverters are a quality solar inverter manufacturer. A German company founded in 1981, the longevity of the brand is reflected in the reliability of the inverters. Especially the fully German-made ones made prior to 2017. Since 2017 SMA commenced manufacturing in China and quality control may have been compromised. Up until 2017 and for the first SMA was the most popular solar inverter in Australia.

SMA inverters are known for their advanced technology, such as their OptiTrac Global Peak system, which optimizes energy output by continuously searching for the highest power point of the PV array, even in partially shaded or low-light conditions. Additionally, SMA inverters have a high efficiency rating and are compatible with a variety of solar panel types and system configurations.
