Was the older, pre UL1741, Multiplus II 48/3000/35-50 120V (PMP482305100) approved for UL458?

I find this certificate: [https://www.victronenergy.com/upload/documents/Certificate-Safety-UL-458-MultiPlus-II-12-24-48V-3000VA-120V-080525.pdf](https://www.victronenergy.com/upload/documents/Certificate-Safety-UL-458-MultiPlus-II-12-24-48V-3000VA-120V-080525.pdf) which states conformity for “MultiPlus-II 48/3000/35-50 120V” (and calls that a model number), but has no specific part numbers listed, and by the date I assume it’s only for the newer PMP482305102, which is also UL1741 listed. But, with no specific numbers, the certificate could be read to apply to both. Same with the UL1741 certificate: [https://www.victronenergy.com/upload/documents/Certificate-UL1741-and-CSA-C22.2-MultiPlus-II-48V-3kVA-120V.pdf](https://www.victronenergy.com/upload/documents/Certificate-UL1741-and-CSA-C22.2-MultiPlus-II-48V-3kVA-120V.pdf)

That seems to be a major flaw in the LabTest certifications, as they could be read to apply to older models known not to be compliant. Guessing Victron erred when submitting for testing by not providing specifics, since the product name was unchanged. I don’t see any way to access the referenced reports, “Refer to LC Listing Report no. 10.00.20469-3\_Rev.D” or “Refer to LC Listing Report no. 10.00.20469-1\_Rev.E” to see if they have specifics.

Why did @nickdb move this from “[Q&A and troubleshooting](https://community.victronenergy.com/c/products/4)” to DIY? The question/comment is not specific to DIY, but applies to _all_ uses of the product. In fact, the certification issue is probably more important to professional installers.

I realize this isn’t a support site, but no response? (no thanks to @nickdb moving it to the wrong place, I’m sure)

HI,

I’d like to second this. Mike, you should re-post perhaps.

This isn’t a DIY question.
