Watts Used Per Hour X Hours of Days Used = Watts Used Per Day

Solar Watts Needed / Hours of Sunlight = Solar Wattage Needed 

For Example: 300 Watts Per Hour X 5 hours of RV use = 1500 Watts of RV Use Per Day

1500 Solar Watts Needed / 5 Hours of Sunlight = 300 Watts of Solar Needed

Simple wattage calculator for devices in your RV

To calculate the wattage of an item it is important to know both the amps and the volts that the item uses. This simple calculator will give you an easy conversion to watts.

The answer to your off-grid refrigerator might just be the Go Power AE-6 kit

Refrigerators in Class A, Class B and Fifth Wheels have gone to residential types. These residentials types will not runn off of your battery bank alone. You need an inverter, a large battery abnk and solar panels to operate seamlessly. A generator on board is always a good choice as well.

Go Power AE-6 Solar Kit

Designed for refrigerators and larger loads

More power from the sun for faster recharge times

Just add a battery bank of 500 to 1000 amp hours, and this kit will usually support your fridge off-grid. There will always be low light weeks where a short generator run or plugin will kepp you going. The AE-6 has the power to keep it charging and running. The six in the name is for 6 solar panels.

Lithium batteries have come down a lot in price over the last 10 years. When we first started selling these batteries, they were hard to come by and a 100 Ah battery would cost over $5000. Today they are much lower cost and the power denisty is getting greater.
