A:Answer Thank you for contacting Renogy. 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 share with us a list of your items with these values, I can see what kind of system you may need. If you have any further questions please let us know by contacting 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.
