Jackery Smart Transfer Switch
The short answer
Jackery lists this part for one power station on this site. Here is what they say.
An electrician must install this
This part connects backup power to your home's wiring. You need a licensed electrician. Most places also require a permit and an inspection.
Do not try a shortcut. Never run a cord from a generator into a wall outlet. Power flows backward into the street and can kill the crew fixing your line. Electricians call this backfeeding. More on staying safe.
What the maker says
Compatible with 5000 Plus
These are the maker's exact words, copied from their own page. We do not reword them. That way you can see for yourself how strong the claim is. "Sold with this model" is a weaker claim than "works with this model".
