Works great! Barely used in an off-grid set up to charge my plug-in hybrid car. System works so well I decided to upgrade to a 240VAC inverter to so I can use a Level 2 car charger. Unfortunately Giandel doesn't sell a 240VAC model in the U.S. market so I purchased a Sigineer inverter which also works great. I am in the S.F. Bay Area (El Cerrito). Purchase price for the Giandel inverter was $629 but will sell for half that at $314 (shipping not included).
