You will need a deep cycle battery bank, either 12 or 24V. If you are planning to use AC power you will need an inverter as well.

Will this unit power a 30 amp rv ac unit?

Asked by Ed July 20, 2020
1
Answer

Assuming 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.

Good kit with panels, cables, connectors, fuses, and PWM controller. Comes with three 100-watt panels and the controller can support up to 500 watts. Controller has Bluetooth capability to connect to the SolarAPP, although I have not been able to get the controller to connect to the app. Also, connecting an inverter to the Load output on the controller resulted in an over-voltage alarm on the inverter. Otherwise, the controller provides a lot of info, settings, and functions for various types of batteries. Overall, it's a good system at a good value for a small installation.
