Will this unit power a 30 amp rv ac unit?
Asked by Ed July 20, 2020Assuming a 120 volt AC unit, it would run continuously at 3600 watts. Assuming ideal mounting conditions and that your panels are in direct sunlight, you could power your AC unit for approximately 15 minutes per day, which is probably insufficient. Don't hesitate to contact Grape Solar at info@grapesolar.com to get assistance in sizing an off-grid kit for your RV.
