All hooked up and everything works..sorta

[fazeshift]

@fazeshift..using a multi, I’m getting 62v floating as you calculated.
Assuming the jumper wire trick you mentioned worked in my case, what would be the permanent fix for this? Any ideas?

The ground/neutral bonding box utilizing the dry contacts on the inverter is probably the most correct answer, though I am failing to find a technical reason why the neutral jumper is "bad" as a permanent fix.

Seems the jumper between neutrals is what watts 24/7 suggests on their MPP units, and he seems to be familiar with the issue.

MPP Solar LV5048 Bonding & Grounding question.

I'm working on slow install of my LV-5048 and I had a question and a crude diagram of my question. 1. Do I bond my Neutral and Ground on the critical loads panel? 2. Should I run a ground wire from my main service panel to my Critical loads panel grounding bar? Im not sure how MPP solar...

Thanks for that, looks like the gang has a working fix I’ll have to try. Neither Signature or Growatt wants to address my missing program 24, so looks like I’m on my own. I wrote GW, and here’s reply. I asked for a copy of this special manual, that doesn’t seem to exist on interweb.
“ I have forwarded this issue over to the team.
They have checked the latest manual for this inverter and confirmed that
this inverter does not have a program 24.”

Guys doing off grid having same issues, but they’re bonding N and G, and bypassing case ground.

Open Ground when testing outlets on inverter

When testing, all my outlets report Open Ground. My inverter is properly grounded to a grounding rod outside, but I believe the reason for the Open Ground, is because inside my inverter the Ground & Neutral wires are not bonded. I'm wondering if there is a shock risk, if there was ever a short...

Made the jump, and now showing ground on AC out. Hope the band aid is bulletproof.

@fazeshift not sure is this addresses your problem, but looks like it might.
