@Will Prowse keeps saying this inverter is UL listed. I am a member of the UL database and it is not listed.
I think you know by now that I'm a huge customer advocate. I'm pretty sure I've made that really clear on the forums in general. I read all the email interactions with this customer. The short circuit timeframe doesn't change the fact that without any load at all his inverter by itself has specifications that exceed those listed by the battery. I like to think I am a very fair headed person and make fair decisions for everyone. I'll be speaking with the team and seeing if we can additionally refund a larger portion of the restocking fee - but I really hate to deviate from Signature Solar's published guidelines as it incentivizes people who received the same information and treatment as everyone else to think that they deserve special treatment and exceptions, but those who play by the rules and read the documentation are punished because they don't. I will be researching this further to see if there are any other extenuating circumstances.
It's funny actually, testing exceeded our newest spec sheet (and the one posted) but I'm sure for liability reasons they updated the spec sheet to reduce or extend specific parameters. So, essentially, the battery returned actually would hold up to either.
they are useless, because when i order a Deye 12k, i do so for 2300 euro for the Deye and 2700 for the sunsynk.
Exactly. I am in another thread right now where James from SS who is boasting that the the LV6548 Errr, I mean 6500 is an Automatic UPS with 20ms transfer times. When I pointed out that 20ms is not transfer time for a UPS and that 5ms and under is considered a UPS time and maybe a few items can get away with 10ms but not 20ms as that will Glitch everything in your house, he quickly had one of his people state that it's actually 10ms not 20ms. I am sure the manual for there 6548 is being redone as we speak.
As far as regulatory approval goes, there isn't a difference between ETL, TUV, and UL listings. Inspectors treat them equally as they are all approved by the US Government as NRTLs. The inverter has TUV certification.
I have a printed manual on my desk from about a week ago - it has 20ms for APL setting, 10ms for UPS.
As Will states in the Video "Everything you see on this wall is UL Listed or Compliant" The problem is the inverter is not UL listed, it is just UL compliant and that is going to be an issue with any inspection.
It's kind of funny you say that because the MPP LV6548 has been TUV certified for a long time and everybody has stated that you cannot get it Grid certified because it is not UL listed. People including Will Prowse.
It is UL Compliant though. Which is what he said. We aren't trying to mislead anyone - we posted our certification documents at the same time we had Signature Solar release the inverter for sale.
The broad answer is no - Signature Solar researches every RMA and refund request, so I'm sure there will be cases where a refund is appropriate. Really, anyone attempting to pass an inspection should always have their system designed and submitted for approval before making purchases. If you are buying all your equipment first in these cases, you are going about the entire process the wrong way.
In the first video on the Inverter itself Will stated the Inverter was UL Listed and would pass inspection.
I wish the solar industry would decide what this means - the unit isn't 'grid tied' in the sense it will sell back to the grid (I only point this out because that's what a lot of people take 'grid tied' to mean).
We made several changes to the design of the unit that were typically the reasons that the MPP didn't pass inspection - being UL Listed is not a requirement in most jurisdictions, just the requirement that a National Recognized Testing Laboratories (NRTL) has tested the unit to certain specifications. In most cases, TUV, UL, and CSA are all acceptable and recognized. Of course there are certain jurisdictions that require one or the other, but it's rarely a requirement itself.
The restocking fee and shipping are always on a case by case basis. I can tell you that in 95% or more RMA/refund requests, Signature Solar does not assess these charges. They are pretty clear about this on their website and during the process.
I'll be the first to say it, we 100% recommend people get approval first if this is a requirement. It has never been the stance of EG4 or Signature Solar to simply buy our stuff and hope it passes. In fact, it hurts us more often than not - as I said before we rarely charge restocking fees and shipping, so that's out of pocket for us. But in the end, we can't stop adults from making decisions - there are people who drive cars without licenses etc so we can only give as much information as we can and hope people make the right choices with that information.
I'm currently running my AC with easystart 368 it is a 3.5 ton unit. It is pumping along with no problem utilizing a single 5000es-us from signature solar it hits 70% on Startup and just back down to 50% steady. At night I utilize two of the EG4 48v 100ah batteries. I'm surprised your 7K generator cannot start it. Are you sure it is wired correctly?
LOL No!!This thread is increasingly nasty and mean spirited, not what I’m used to seeing on the forum over the years.
No wonder very few companies are on here.
Amazon has ruined the world! Everything has free shipping free returns. With this they have created a monster of self-righteous customers that take no responsibility for their self.This thread is increasingly nasty and mean spirited, not what I’m used to seeing on the forum over the years.
