My setup is a 220v high frequency hybrid inverter with input and output connections. But I don't use the input port which takes in L1, L2 and grounds. Instead I feed the output to a step down transformer to produce 120v. Then I feed the transformer 120v output to the inverter side on the transfer switch and then I connect the L1 and neutral coming from the main panel disconnect to the grid side of the transfer switch and then I connect the sub panel L1 and neutral to the load side of the transfer switch. My sub have all my load breakers.
My main panel disconnect with just the breaker for the grid alone is located close to my solar setup .Therefore can I use the neutral from it to connect to the load neutral slot on the transfer switch???
Instead of running a 30feet neutral wire from the sub seeing that the neutral in the main panel disconnect is the same like in the sub.
I am only using 1 phase 120v that's why i am only working with the L1 & N from the grid and the L1 and N coming from the step down transformer.
Please note that the neutral and grounds are tied only in the main panel disconnect. Which setup is the correct one and will the switching of the transfer switch to either solar or grid goes smoothly without any issues?
Please note the transfer switches only 2 legs at a time. Either L1 and L2 or L1 or N
