I have a bit of questions regarding my new potential setup project.
I am looking to put 8 410w panels on a wooden frame mounted to a trailer that would sit in the driveway in summer and in the backyard in another location in the winter.
I am looking to use an EG4 3000EHV-48 again for this setup. But it will be used similar to the handcart builds.
So my questions are surrounding grounding and wiring.
My plan was to leave it plugged in to an outlet in the attached garage most of the time letting it power things with utility as backup, but remain mobile and able to cart around to the other side of the property by being unplugged.
During this i had planned to run a grounding cable from the array on the trailer in with the conductors in a flex conduit to the inverter and let it travel thru the home from the outlet and bond in the main panel to which is connected to both the water pipe coming into the house - and an existing grid tied solar system which is connected to the water pipe as well , but has its array grounded to a separate grounding rod outside the house. (Which confuses me , but was inspected and passed and installed by a major installer)
Now comes the tricky part, when in either the driveway or the backyard positions and disconnected from the house i am now without a ground. So do i put a grounding rod by the driveway and 1 in the backyard with posts with a quick disconnect attached to the ground cable with a switch so that i can connect to and turn on the ground path to whichever rod i am closest to when i move the array on the trailer? Or is there an easier way to do this?
The harder way of doing it i had thought would be to have a switch by the inverter instead for the ground to be Grid or Remote and to leave the grounding rods connected but buried and connected to the other grounding rod hundreds of feet on the other side of the property AND i'm not sure if i would need to connect to the water pipe as well? (this seemed like something i want to avoid having to do) And i'm assuming when they added the grounding rod it became the grounding rod and the water pipe is just considered being grounded to it as well now and i wouldn't need to bother connecting to that as well if i had went this route.
Also is there anything i may be missing in my thinking ? Thanks.
