The residential SG series of solar inverters from Sungrow have become very popular due to the competitive price and great reliability. The strong sales figures show they are now the second biggest selling solar inverter in Australia by volume, coming second only to Fronius (according to Formbay data). Also, Sungrow has a great reputation for quality compared to many other Chinese manufacturers, along with good service from the Sydney based support office, which has further helped improve their status.
The Sungrow SG3K-D, SG5K-D & SG8K-D premium inverters are an ideal solar system solution for private & residential homes. They are a very reliable and affordable inverter. As they are a dual input MPPT inverter they can handle modules being installed on different sides of the roof (2 strings). These inverters are installed for single phase systems.
The SG series are lightweight, transformerless, string inverters with a wide MPPT voltage range and Wi-Fi communications included. Like most modern string inverters, the Sungrow residential inverters are cooled via passive cooling using a large rear heat sink. Due to the efficient design, no power de-rating is specified to occur below 45 degC ambient temperature, which is impressive for a passively cooled inverter.
