Thanks for your input on the UL 1741 standards conformance process. I have been reading over the documents from my utility for their requirements, and they are vague about what they require as proof that the device is certified. It is possible that they might accept the form that SRNE has on...
I completely agree that the 3k inverters are only exporting power in the SUB mode. I tested all of the modes extensively over the past several months while arguing with the EG4 tech people that they had an issue. They wanted to blame it on my installation with every lame possibility you can...
I installed my setup last October and was running SUB mode so that I could utilize solar when it was available, and switch to utility when it was not. If the grid went down, I automatically went to battery power. In the SBU mode, I found that the lights were always flickering and my wife did...
It is a possibility, as it did not show reverse power in Solar Assistant, but I cannot be sure that the smart meter will not still detect something. My unit is still with the warranty service technicians (for over a month) so I could not try it if I wanted. Since I am now on the utility...
First I want to thank all who are replying for their help. The solar panels I installed are 550 watt bifacial Renogy units. Currently they are in a series mode to give me a voltage that would run the inverter I bought. I installed these on a detached shed roof behind my home and ran 10 awg to...
When looking at the documents on some of the lower wattage panels, I am finding that they give a suggestion that they may be trying to get UL 1741 certification, but there is no actual certificate, The CE mark is not the same thing in the United States and is not recognized by the utility...
In reference to the 6000 XP power information, I downloaded the manual for installation requirements and used these to submit the plan to install that the power company will have to approve. I realize that their numbers are definitely conservative, but if there is a problem I am back to where I...
While I was waiting on a reply from my power company, I have been doing more research into the Solark 5k unit. Solark seems to no longer cover any of the lower wattage units on their website. I guess there is not enough business in the lower end units to keep them in this market. I think that...
The EG4 3k says it is and off grid AIO as well, but since it occasionally backfeeds the grid, it means they have a say in it being plugged into their utility. This is not a legal issue I wish to fight in court.
I looked at the SRNE unit that was suggested, but even though I am sure it is a good unit, it is the same basic unit as the other 3k inverters. I also cannot find a UL 1741 certificate.
I checked out the SolArk 5K-1P that was suggested and it sounds like a pretty good match for my requirements. It is a bit of overkill for my needs, and I would still have to go to 8 awg wire for the power i/o, but that would be easy enough. It is about twice the cost of the 6000 XP, but it...
I understand that these are CE mark and ETL tested to comply with UL 1741, but this is not the same as being UL listed and certified by a national testing agency. Utilities in our country require that they have an actual certificate to show this before they will consider them. The companies...
My loads on the subpanel were around 300-500 watts average. The only inductive load I had was a refrigerator and the rest were lights, coffee pot,etc. When I looked at my data on Solar Assistant after I was caught, I could occasionally see a negative wattage showing up going back to when the...
Doing the testing for a product in their lab and saying it meets ul 1741 requirements is not the same as getting UL Listed. If you look at inverters online, you will see that only a few will say that they are UL 1741 listed. This is because the process a recognized lab must use to legally...
After receiving a call from my utility company about backfeeding the grid with my EG4 3kw inverter that I was running in an off grid mode, I am attempting to replace this unit in my system. I plan to try to get a level 1 connection permit from Kentucky Utilities since they tell me that this may...
Back in March, I also received a call from my utility company, Kentucky Utilities, that I was occasionally backfeeding the grid. I had decided last year to put in an EG4 3k 48 volt system as a backup for a couple of critical load circuits, and had been running in the Solar/Utility/Battery mode...
