Using manual transfer switch to distribute power

[TimeOutside]

The application is providing AC to a camper. The goal is to provide AC input to charge a solar 'generator' when the camper is connected to shore power. Then, when the camper is disconnected from shore power the transfer switch is moved to Position #2 for the solar generator to provide AC power to the camper. To accomplish this goal I tap into the camper's existing distribution panel bus bars.

1. When the manual transfer switch is in position #1
   a. Shore power is routed to a Jackery solar generator. The Jackery is limited to a 15 amp AC input, which is the reason for the breaker.
   b. AC output from the Jackery is disconnected.
   Note: AC output from the Jackery is off by default. A button on the unit must be pressed to turn on AC output.
2. When the manual transfer switch is in position #2
   a. AC input to the Jackery is disconnected.
   b. Power is routed to the camper's distribution panel from the Jackery's AC output.
   Note: The circuit breaker is needed here, but I provided it as an additional cutoff.
3. When the manual transfer switch is in position #0
   a. The Jackery is isolated from the circuit.
4. Note: There are positions still available on the transfer switch. I intend to use a couple in Position #2 for some DC distribution that is completely isolated from the AC distribution.

Is this wiring correct? If not, what corrections do I need to make?

Thank you,
Andrew

The diagram looks okay to me, except I'm wondering if the neutral needs to be run through the transfer switch as well as the hot, in order to keep the output/input from/to the Jackery separate (except for the ground).

I'd greatly appreciate some input.

Thank you,
Andrew
