The SW requires and inductor to operate in current mode for grid tie. Maybe someone remembers the part number. It may be hard to find. David Katz

Date: Sat, Jun 30, 2012 5:10 pm RE-Wrenches: Have a potential customer who wants to connect to the grid after many years of off-grid living. He is asking if his older Trace inverter (SW4024 inverter; Date of manufacture: 3rd quarter of 1998; S/N: W07878; 120 volts and 33.3 Amps) would still be OK to use in a grid-tie system. What say you? Does it still comply with the latest standards for grid-tie inverters? Should he start over with a new inverter? Bob Clark SolarWind Energy Systems, LLC
