This inverter has a range of benefits. One of the key benefits of this inverter is the dual input section to handle two strings with independent MPPT especially useful for rooftop installations with different orientations (i.e. East and West).
Its transformerless operation improves the max efficiency up to 97.6%. The wide input voltage range makes the inverter suitable to low power installations with reduced string size.
This inverter has been designed as a completely sealed unit to withstand the harshest environmental conditions. The Sununo-TL4.4K/5K/6K provides maximum flexibility for plant design, and is the first choice for demanding generator designs.
