What size solar system is needed to run a chest freezer?

Answer 1

If you are referring to solar-electric power, there are no specific power requirements for a chest freezer. The problem is that most solar-electric systems are designed to be connected to the normal power grid. If you have a power failure, your solar power system will automatically shut down.

This is to protect electric utility workers from being shocked and injured by solar power systems providing power to a neighborhood that has been disconnected from the normal grid. In order to use your solar system even when the grid is down, you'll need a device that will isolate your solar system from the grid when the grid power is down.

THEN we can talk about how much solar power you'll need to power your freezer. Remember that when the Sun goes down, you'll lose your solar power; if you intend that the freezer should continue to work at night or bad weather, you'll need either a backup generator or a whopping huge stack of batteries.

Will you want power for anything else? Lights? Refrigerator? Furnace? Add it all up and then double it, so that there will be enough power tomorrow to not only run the system but also recharge the batteries.
