I’m looking for an inverter to power our 45 inch tv while camping. I’m looking to install dual 12v marine/rv batteries to pwr the inverter.

Hi Happycamper, Thank you for sending your inquiry and interest in our products. To properly size a system to meet your needs we would need to know the voltage, amperage, or wattage, and run time of each of your items. This will help us determine how many batteries you would need to run these items for a day and how many panels you would need to charge those batteries within a day of peak solar production. If you could give me a list of your items with these values, I can see what kind of system you may need. Hope this answers your question. Should you have any questions, please contact us at 909-287-7111, Monday through Friday 8:30 am - 3:00 pm PST, and expect long wait times as we also are migrating to a new phone system. Again, thank you for your patience.
