Would like to get 6000xp and eg4 battery for my off grid setup. I have a reliance transfer switch with a delta pro currently. When I try to AC charge my delta pro, which is connected to the transfer switch it will trip my gfci outlet (same circuit as the ac charging outlet). From my google search, it’s about neutral ground loop created. So I don’t use the ups feature of delta pro for now, only use it as a backup.

Moving on, would like to get 6000xp to connect to the transfer switch to backup and offset part of my electricity bill. Planning on connecting the load of 6000xp to reliance transfer switch. My question is, will I encounter the same gfci tripping problem? What’s the correct way to connect the neutral and ground between 6000xp to transfer switch?

Thank you everyone in advance.
Jeff
 
This search will tell you want you need to know. "Reliance Controls switched neutral" There is a lot of info at Reliance about neutrals.

I tried searching before posting. I couldn’t determine which is the correct/easy way to resolve it. It would be great if you can either point me to the right direction or give me some more direct help. Thanks
 
I’m curious how everyone is doing it off-grid? I can’t find a YouTube video talking about this issue. Anyone connecting 6000xp to a reliance transfer switch here? Everyone is installing that neutral switching kit from reliance ?
 
Not necessarily. If the only use of the neutral is the inverter I wouldn't think you would a switched neutral My 6000xps share the grid neutral. I run a critical loads panel and have experienced no issues.
 
Thanks for responding. For your critical load panel, do you have separate ground and neural bar? Or everything is bond together ground and neural. Maybe I should just get rid of the transfer switch and install a critical panel instead?
 
No the ground and neutral bus bars are separate in the critical panel. I have a grid supplied bypass circuit which is not normally used but the ground and neutral are always connected. So my neutral and grounds are shared between the grid and solar derived sources. I've had no issues. The only ground/neutral bond is in the first disconnect/meter panel supplied from the grid.

I have a 6000xp directly connected to a Reliance 10 circuit transfer switch. When I flip the switches on the transfer switch, the corresponding GFI breaker in the main panel trips. When I called Reliance, they said "yep - it does that". They went on to say "your circuits work, right?" which I said was correct. They said I didn't have to do anything but flip the main panel breakers back on when disengaging the transfer switch. I thought this was odd but figured they knew what they were talking about.

Had the same experience when I used a Reliance 10 circuit transfer switch. Just finished putting in a sub-panel and removed it.

Did you get a permit and everything to have a subpanel installed? I just didn’t wanna go that route becsuse of permit …

I did not get a permit. Read a lot here, read NEC 2023 sections that applied to my install. Have to admit, it was a pita due to recessed panels and a shear wall. Off the next two weeks so finishing the drywall/mud/paint.

Thread 'Recessed 100 amp sub panel install'

I must be missing something. In this video at the 14:00 mark he said that 100amp requires 1/0 and is a new requirement for copper. I thought on the ampacity chart that #3 is fine for both 75° and 90°.

Wow ... I literally just got to that point yesterday. I have not powered up my battery or inverter, but I hooked up my 6000xp to the 10-circuit Protran 2 and simply set all the switches to line power. The single GFI circuit wired into the Protran tripped its main panel breaker. I reset the breaker and everything worked fine.

I would have been obsessing about this if I hadn't seen your post. I think I'll just leave my set up as-is and reset the main breaker whenever I switch over ... which should be rarely.

FWIW:

I had a recessed main panel also and ended up routing my wires through the wall below the panel after mounting a box conduit tray below the panel and drilling through the back of it. I'd first added a 1/2" plywood as a mounting surface. My Reliance Protran wiring was routed through an elbow and then through a hole in the same plywood.

Exactly what I plan to do. How do you wire up to charge your battery from AC？ the load of 6000xp connect to the transfer switch generator in

Question, what is behind the plywood/LB to connect it to your main panel? This is where I struggled initially which I then decided to jump out of the wall cavity using the wire trough up high for AC in on inverter and the return power from inverter.

I installed a 50A two-pole breaker into my main panel and routed red/black from that breaker, through a disconnect switch, and then to the "grid" input of the inverter. I also ran a ground and neutral wire over to the inverter from the main panel.

I have not powered anything up yet, so I'm not sure if there are any inverter settings that have to set in order to charge the battery via AC.

I simply have a 1-1/2" hole in the drywall behind the plywood and routed the wires up by hand through a knock-out in the bottom of the breaker panel ... with an insulating bushing in the knockout hole. The wires are "bare", no conduit or anything behind the plywood. They lie between the insulation and drywall in that cavity, so no abrasion issues. It's a very short run.

Please let us know how it goes after you setup everything. I will have basically the same setup. How about 6000xp load , hardwire to transfer switch input ?

Got it. I didn’t want the bare THHN in the walls which is why I ‘engineered for the lack of a better term’ the way I did to jump out of the drywall via recessed box with extension ring from main panel then 6x6x12 wire trough above.

I think there are only 4,683,134 different ways to do this :rolleyes:

I picked one way based on a YouTube video I saw for something "similar"

No.

There is a ground wire and neutral wire in the bundle of wires routed from the transfer switch to the main panel. Hook up that ground wire inside the main which is connected to the metal case of the transfer switch. Ground is now done. The neutral wire does not have to be connected as the inverter already has that connection. I was confused about the neutral also, so see the related posting in:

Thread 'Wiring Question - Pro/Tran2 Transfer Switch'

I'm installing a Pro/Tran2 Transfer Switch (10 circuit) with my 6000xp Inverter. When I attached all the wires from the Transfer Switch into the Main Panel, there was also a ground wire and Neutral wire that got connected. The ground wire from the main panel is attached to the casing of the transfer switch, but the neutral just hangs out loose within the transfer switch casing (see pic below).

My main breaker panel does not have specific bus bars for ground or neutral, so both ground and neutral are mixed together on the bus bars within the main panel.

I also ran a separate ground and...

What gauge wire did you use for GRID? The manual states 8 AWG but, a 50A breaker usually requires 6 AWG, does it not?

I too have a 50 A breaker in my main panel tied to GRID. Charging from GRID works fine other than a hum that occurs when the changeover occurs from GRID back to inverter on a couple of devices. These devices are two battery backups that contain low impedance transformers in them. Other's have noted a similar hum and there are a couple of threads on it.
