Power One PVI-4.2 Transformerless 4200W Inverter

Aurora® grid-tie transformerless inverters offer a unique combination of ultra-high efficiencies, installer-friendly designs, long service life, and competitive initial acquisition costs; signifi cantly increasing return on investment in solar-power installations.

Industry-Leading Features and Performance

• High efficiencies deliver more energy – up to 96.8% (96% CEC).
• Two inputs with independent MPPTs, optimize power from multiple arrays oriented in different directions.
• Compact size and high power density: 4600W max of output power in a box size of just 33 11/16” x 12 13/16” x 8 1/4”.

Unmatched Applications Flexibility

• Full-rated power available up to 50 °C ambient temperature.
• Two input sections, with parallel option, with independent high-speed MPPTs, optimize energy harvesting from multiple arrays oriented in different directions.
• Wide MPPT operating range: 90 to 580 VDC.

Field-Proven Reliability

• IP65 (NEMA 4) rated enclosure withstands the harshest environmental conditions.
• Front-mounted heat sink resists contamination, enhancing cooling and increasing reliability and long-term efficiency.
• Grid-connected operation according to international standards, UL1741/IEEE1547 & CSA-C22.2 N.107.1-01.
• 10-year warranty, optionally extendable to 15 and 20 years.

Installer Friendly

• Reverse-polarity protection minimizes potential damage caused by miswiring during installation.
• Front-panel mounted LCD display provides real-time updates for all critical operating parameters.
• RS-485 and USB communications interfaces.
• Integrated DC switch available in compliance with NEC Standard, Article 690 “Solar Photovoltaic System” (USA).
• Anti-islanding protection.
