The ABB transformerless inverter is a rugged outdoor inverter that has been designed as a completely sealed unit to withstand the harshest environmental conditions. One of the key benefits of this inverter is the dual input section to process two strings with independent MPPT especially useful for rooftop installations with two different orientations (ie East and West).
The ABB model series A includes an integrated Arc-Fault Protection feature to comply with new NEC requirements. The high speed MPPT offers real-time power tracking and improved energy harvesting. The transformerless operation gives the highest efficiency of up to 96.8%. The wide input voltage range makes the inverter suitable to low power installations with reduced string size.
