US Certification for Victron Inverters

I'm trying to figure out if Victron inverters are US certified?

My solar installer is saying he can't use Victron because it won't pass inspection in Washington state (US).

I found the below certificates on victron's site, but my installer says he doesn't see a listing for US or at least one that Washington State recognizes so he can't legally install it.

I sent a mail to Victron to ask for clarification, but figured I might post here as well just in case someone here was able to help figure this out.

I'm going to assume from the lack of response here, and also not hearing anything back from my email to Victron support directly that this is not officially supported for US residential instillation.


It's a shame, I need to be legal in my area though and so I'm off to look for another inverter.

There are MultiPlus 12V 3kVA and 24V 3kVA models in 120V that have been certified to UL1741, CSA 22.2, and UL 458 for North America. Please see the links below from the Certificates section of the Victron Energy website. Note several other products, such as the SmartSolar and BlueSolar MPPTs also have been similarly certified, with more models to follow.

Thank you very much for the above links.

I double checked with a local electrician, and it is indeed the LabTest certification mark that is needed in order to pass inspection here. However, it looks like only the 12V and 24V MultiPlus are covered in the in the links you provided.

Unfortunately, I need a 48V inverter for my instillation.


I'm guessing the answers to my below questions are going to be no, but just in case, I'll ask them point blank.


The certificates linked above (both) specifically lists the 12v and 24v multiPlus inverters.

Does this mean the 48v multiPlus inverters are not LabTest certified?

Does Victron have any LabTest certified 48v inverters?

Are there any Quattro inverters covered under a LabTest certification?

I was more interested in the Quattro line as it has higher capacity ratings, but could definitely make due with multiPlus if needed.

No 48V model is certified yet indeed. Soonest will be somewhere next year. We’re aiming for earlier rather than later in the year. Though for now thats all future and nothing definitive can be said about it.

Note that this will be modifed hardware: anything you buy now will be different from the 48 V hardware that we’re working on for UL1741(SA).

or other Victron Staff able to clarify...

Per the two aforementioned UL Certificates Rich has shared, both do not mention specific SKU numbers of the MultiPlus units bearing the certification(s), just the product model description.

For the MultiPlus 24/3000/70-50-120V, there are two SKUs:

PMP243021102 - non certified

PMP242301102 - UL certified

Is there a difference in the actual hardware in these two SKUs, or does the second one simply bare the certification logo on the cover?

I ask because in this thread, mvader mentioned the following regarding future certification of 48V models:

Note that this will be modifed hardware: anything you buy now will be different from the 48 V hardware that we’re working on for UL1741(SA).

Is there a difference in the MSRP (list price) between the two?

Thank you!

Is there any update to the status of the UL 1741 certifications in the past year?

Another request for updates of certification for 48V Quattros ... We have a pair of old Trace SW systems that failed, and I would really like to put in a Quatto 10k. If not it will be a pair of Schneider XW+5548 ...

Local certifications requirements are best directed towards the local installers:

https://www.victronenergy.com/where-to-buy

You can use the map, or Select USA, Washington

If they are unable to help, please try and contact the Victron Sales Managers for North America: https://www.victronenergy.com/contact#Sales_Manager_North_America

In this case Rich has already answered, but those references are useful in the future if someone else is looking for the up to date information.

You should check again. I'm now seeing this model is now available on my local Victron installer website: https://www.thesolarbiz.com/victron-multiplus-ii-48-5000-70-50-inverter.html

Thanks @Oliman for the question and @RichS for a useful answer. I don't have another answer, but a couple of related questions. First I'd like to point out this Victron Blog post (BlueSolar MPPTs awarded UL 1741 and CSA C22.2 certification) from John Rushworth, July 24th, 2017 which says that all 120V Multi's and Quattro's are expected to be certified by "the end of the year" (2017). Obviously that didn't happen. My first questions: Why not, and is it likely to happen anytime soon now? Is the newer UL 1741-SA getting in the way here?

My second question is whether the existing UL Certified Multiplus models can be used to run ESS in a UL1741 Country (eg: the USA)? If so, will UL-1741 appear as an option when choosing a country code for these models?

And, finally is there a recommendation for an energy meter to be used for the North American standard split-phase power system? I gather that a Carlo Gavazzi EM24 model might work due to another question & answers on this forum, but I've seen no input from Victron on this question. I am interested in running a parallel system that would require a meter.

Thanks in advance for any answers that anyone here might have.

You can pay to have the Victron inverters certified when they will be part of a certified system under programs such as SPE-1000. I had the Quattro line from 4 years ago approved this way, and then I was able to sell them under that approval in small numbers (under 100 per year).

Intertek did this inspection for me and the cost was mid 4 digits.

The inverter they tested was put through hell, and it passed without issue.

Keep in mind this is in Canada, but it's likely you have similar programs in your area. Just call the inspection companies directly and ask about special accreditations for low volume manufacturing.

Hi @Vincent I am very interested about this certification you are mentioning above as we are trying to certify our systems in the US and Canada and seems that we can share our experiences on this together and hopefully benefit from each other. Would you mind to give me your contact details so we can have a chat?

This thread being half a decade old, much of the information here is outdated. Please discuss available certifications with your local distributor and installers, which you can find here: https://www.victronenergy.com/where-to-buy
