Yes I’m looking for input to make the changesThis looks very similar to another thread where @FilterGuy told you that without an interlock this was a dangerous setup. Has anything changed?
There were a few positive comments and you could start there. Does the block diagram which @Mattb4 posted make sense?Yes I’m looking for input to make the changes
Yes in my mind that was my intention just what you wrote, with no examples to go by, but now it makes more sense to shut off the main breaker and to energize my main panel from the sub panel/ inverter to power my load , this is the inverter I have, and I would not dare to try and to switch any thing on until i knew that it was safe and functional,, I also want to thank those that have added a post that’s moving forward to help me with this project , also thanks to all the others for their negative responses, I understand where your all coming from, I’m probably older then most of you and have tough skin ? ?I suspect you are correct, an effort to have dual sources of power
I think he wired every circuit breaker in the main panel with an extra wire coming from the sub panel, I guess the plan would be that you could turn off the breaker in the main panel, and turn on the breaker in the sub panel and even with the CB in the main panel off, the circuit would be powered by the sub.
a frankenstein for sure
One thing I noticed was 40 amp breakers had same size wire as the 15 amp please get a NEC chart for amp ratings for size and insulation rating this will tell you the size of wire and type of wire for the different amp breakersYes I’m looking for input to make the changes
if you insist on powering your main panel from the sub panel with the inverter, then you need a generator interlock in the main panel but that needs an extra breaker in the main panel at top right, and you have no room in the main panel.Yes in my mind that was my intention just what you wrote, with no examples to go by, but now it makes more sense to shut off the main breaker and to energize my main panel from the sub panel/ inverter to power my load , this is the inverter I have, and I would not dare to try and to switch any thing on until i knew that it was safe and functional,, I also want to thank those that have added a post that’s moving forward to help me with this project , also thanks to all the others for their negative responses, I understand where your all coming from, I’m probably older then most of you and have tough skin ? ?
Thank you, this is a very old house, my wife’s parents and I’m sure the panel was probably from the 50’s, I’m seriously looking into changing it at this point, I am greatly appreciative for all the positive feed back ?One thing I noticed was 40 amp breakers had same size wire as the 15 amp please get a NEC chart for amp ratings for size and insulation rating this will tell you the size of wire and type of wire for the different amp breakers
I have both panels and batteries, I just wrote that I’m seriously changing the panel out , thank you for your positive input it’s greatly appreciated and I know I have many changes to make at this time ?if you insist on powering your main panel from the sub panel with the inverter, then you need a generator interlock in the main panel but that needs an extra breaker in the main panel at top right, and you have no room in the main panel.
also if you did that you are setting up an either/or situation. either using all grid or all inverter.
the ability of your inverter to use SUB mode is important and you would lose this option
do you have solar panels or just batteries ?
your welcomeI have both panels and batteries, I just wrote that I’m seriously changing the panel out , thank you for your positive input it’s greatly appreciated and I know I have many changes to make at this time ?
I see a metal conduit system so no ground wires required. The conduit is the ground. Since this is a service panel the neutral should be mechanically and electrically connected to ground no ground bar would be needed, land all the neutrals and ground wires (if they exist) on the neutral bar. Just a note for you DIYers this is the only place that would be permitted, never in a sub panelyour welcome
in looking again at your main panel, I dont see a ground bar or any ground wires
can you confirm this ?
are all the outlets in the house the old kind that only have 2 slots ?
maybe all the wiring in the house have no 3rd ground wire, just a hot and neutral, we will have to think about the implications if that is the case
Well… I would certainly recommend taking detailed pictures before you try to move anything.I have both panels and batteries, I just wrote that I’m seriously changing the panel out , thank you for your positive input it’s greatly appreciated and I know I have many changes to make at this time ?
good information. thanksI see a metal conduit system so no ground wires required. The conduit is the ground.

Looking at this picture, which one is the main panel? The left 100A panel, or the right? Looks like a 100A feed from the left, and the right is being powered from somewhere else?Will Prowse if you could give me you input I would greatly appreciate it.
WILL, My main power is on the left side,, my auxiliary panel that’s connected to the inverter is on the right side, I am back feeding the wires from my inverter auxiliary panel to the main panel circuit breaker wires,, which means that I would have to shut off all the breakers in the main panel from the power source in order to feed the wires from my auxiliary to the house wires! In my mind, I am providing the hot power from the inverter and auxiliary panel to the wires only in the main panel ,,, I so far have not connected a neutral wire from my inverter/auxiliary panel to the main,, as you see I have two wires ready to install into the mains neutral if this is correct ? Can you please advise me if this neutral wire is needed from the auxiliary panel ? Also the ac 240 input on the inverter has line 1 and 2 and shows ground, my feed from the main panel is 2 / 30 amp breakers the does the 3 rd wire go to a ground on the panel? I see that the wiring from the neutral goes out of the box to the water pipe assuming that it’ was built that way many years ago, do I tie into the neutral bar with that ground wire for the inverter ?

you are correct. the main panel is on the left, the right panel is powered by the inverter, its not really a sub panelLooking at this picture, which one is the main panel? The left 100A panel, or the right? Looks like a 100A feed from the left, and the right is being powered from somewhere else?
