Power-One PVI-4.2-OUTD-US-A 4.2kW Aurora Transformerless Inverters

PVI-4.2-OUTD-US-A 4.2 kW Single-Phase Transformerless Inverter with Dual MPPT & AFCI

The most common residential inverter is the ideal size for an averagesized family home. This family of single-phase string inverter complements the typical number of rooftop solar panels, allowing home-owners to get the most efficient energy harvesting for the size of the property. This rugged outdoor inverter has been designed as a completely sealed unit to withstand the harshest environmental conditions. One of the key benefits of the Uno family of single-phase inverters 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 high speed MPPT offers real-time power tracking and improved energy harvesting. The transformerless operation gives the highest efficiency of up to 97.0%. The wide input voltage range makes the inverter suitable to low power installations with reduced string size.
