EG4 6500EX-48 torque spec for PV input

[boxvan]

The EG4 6500EX-48 manual on page 15, step 3, reads: "Make sure the wires are fully inserted and the terminals are torqued to spec." But I don't see the spec anywhere. I know a lot of other people are using this model so I thought someone might have encountered the same issue and found a resolution - does anyone know what the spec is? I'll call EG4 Signature Solar next time I get the chance during business hours to check, but that may be a few days due to a weird schedule.

Don’t know what the official spec is since it’s not in the manual, I just made it nice and snug without over-tightening.

If you do find out, please share!

Will do for sure! Not sure if it helps at all but here's a photo of the mysterious fasteners (banana-coloured tape in cm for scale):

Update: I talked to Nick in tech support at Signature Solar today and he said they've gotten the question before, but there is no torque listed for it, so I cranked them down the same way you mentioned and I guess use cable clamps as an additional precaution.

Thanks for checking! Guess I’ll have to add that to my list of documentation inconsistencies/oddities.

Go back after a few weeks of use and retorque every cable connection especially stranded ones.

More follow-up: go ahead and remove one item from your list; I got another update today from tech support at SS and we have a spec now!

I did a little digging to get the correct torque specs, but it looks like you should torque the terminals to 0.8 N•m (7 lb-in). I apologize for the oversight in the manual, and will let EG4 know that the manual for the 6500 is missing these specs. Thanks for contacting us about this!

Awesome! I’ll write that down in my copy. Thanks again for checking!
