The transformerless single-phase inverters have the highest peak and CEC efficiencies, dual MPPT and best performance specs in the industry today. They are built for residential or small commercial installations using single-phase power. A rapid shutdown combiner option may be added to the PVI 3800-7600TL to comply with NEC 2014, Article 690.12.
The PVI 14, 20, 23, 28 and 36TL transformerless inverters are designed with high reliability, efficiency and to be easily installed. These three-phase string inverters are small, lightweight, compact inverters utilized in commercial installations. They have dual MPPT tracking zones and a wide MPPT range.
The PVI 50-100KW and SGI 225-500PE inverters are slated for three-phase commercial installations. Each inverter is designed for easy installation, outdoor resistance with the highest reliabilities and efficiencies in the industry. The state-of-the-art power stage technology houses all of the sensible electronics.
Utility-scale inverters and inverter solutions range from 500 kW to 2 MW. Each inverter or inverter solution is designed to provide customers with the reliability and efficiency desired for large-scale and utility-scale installations. The SGI XT and SGI XTM series’ are external transformer inverters and contain redundant power stages (contain all sensible electronics), therefore a solar array will function with a power stage down. The Megawatt Solar Stations (MSS) connect inverters to medium voltage switchgear to provide a direct connection to the grid.
