Signature Solar EG4 6.5K Off-Grid Inverter | 6500EX-48

[Chaunbot]

Signature solar reached out to me today and resolved my issues. I hope the 61 error code is resolved quickly as I know it is close to if not already figured out.
Thank you signature solar I appreciate it greatly

What was the solution?

What was the solution?

Tech support was able to help me out with settings. On the error code 61 it is different depending on setups so I'm not sure on the solution for that yet.

This is how my single inverter was working, would show fault 61 but has never turned the inverter off until a few days ago now it wont restablish.

Won't reestablish com either. Don't have time to re-pin another cord, too many irons in the fire. EG4 setting seemed a bit conservative anyway.

Yeah other than the constant beeping from fault 61 (muted after the first day) the inverter kept going etc. The error seemd to be mostly at the top or the bottom of the battery SOC then it progressively happened more and more, now nothing. I think sunday was the first time the inverter powered off with 30% SOC on the battery. After it powered off the battery hasn't communicated since.

 

[12VoltInstalls]

Just because everyone is telling me that it can pass inspection does not mean I can make a consistent or reproducible recommendation for install. I also had a few engineers message me specific areas and codes that need to be considered. And they were right.

Not trying to be assumptive, obnoxious, or demanding but *if* someone bought a fixer-upper or otherwise distressed suburban to do the maintenance and upgrades to flip and as part of that got all the documentation together and applied for a permit in say… Las Vegas…
That could be an initially expensive but fun way to do a series of somewhat longer videos showing the steps, hurdles, successes, failures and problems of actually getting a TUV tested box to pass. Or not.

Just a thought. DIY Solar stepping into a different realm for a bit would be a fun weekly show to watch imho

Is there any plans on making a 10/12 or 15k split phase unit that is stackable? It would be nice to have higher wattage units with a more robust surge capacity and split phase so you don't have to buy in pairs right out of the gate. Perhaps MPP can build your units with higher end parts for a more tier 1 reliable system but more competitive price? And, with UL listing? Also, do you guys have any plans on making distribution panels like the mini and full ones for the conext which are also UL listed? If so to any of this do you guys have the specs and timelines / potential price? You should consider having a upcoming new products page on your site. Also, it would be awesome to have the ability to monitor all of this with a built in web server or something for local lan; I don't want to have my system talking to the CCP ..especially in these times of potential war. I don't want them to have any insight or access to my system. Somebody needs to compete with the reliability and build quality of solark / outback skybox but with a much better surge capacity and more competitive price.

We have a few things in the pipeline, but I don't think we have anything this large yet. We will definitely explore it if there is a market for it.

This is exactly how I feel. A single, split phase unit that can handle surges (like the 12000T), simple 200A AC passthrough like the Sol-Ark 15k, but stackable and a good amount of solar input.

There's a marked for it..it's called solark. Also, midnight is coming out with a new DIY rebranded SNRE listing for a 10k unit. Problems with that is how they handled the diy line so far and the lack of confidence they have with a one year warranty. Also, SNRE isn't really know for being reliable.

You know, AIMS Power has split-phase inverter/chargers up to 12kW and they offer one of the most efficient 100A charge controllers on the market. They are not stackable, but there is no rule saying you can't run multiple sub-panels and smaller battery banks for larger systems or redundancy. They have 3X surge capability as well, so it's a 12/36kW Inverter.

Curious since you seem to be in electrical engineering support...why can't you connect multiple sources of AC power to the same main box as long as they are the same voltages but not stackable. Why can't you connect two identical aims to the same panel or say a growatt and a mpp that have the same voltage output? I'm assuming cause multiple sources would get out of phase and cause harmonic issues?

It's like a Push-me-Pull-you. They are both trying to regulate the same voltage so they will fight each other. The way stackable inverters work, there is a communication cable and a current sharing cable between them. Then they are programmed such that ONE of the inverters is a master that provides voltage regulation. The rest are slaves and feed-in current like a grid-tied inverter, but don't try to regulate the voltage. AIMS' inverters are not capable of being slaves so they will fight each other.
It is perfectly acceptable to operate multiple inverters feeding multiple load panels.

THNN #6 wire is fine coming from the inverter to the panel, that's what Will used in his as well.

I am using #6 THNN from inverter to panel and it is working well. I tried using #4 THNN, but the terminal lugs in the inverter were too small for #4.

I bought #4 per the manual and haven't tried it yet. Do you say it won't fit?.

Would not fit on my two. Connector terminals inside inverter too small. 6awg is largest that would fit and it was snug!

 

[realpinochet]

Ya, I assumed it might be a little higher. Very pleased though with the numbers Will got.

Legit question, why didn't you know this already since you rebranded this as your product? This is the same as midnight solar apologizing for not knowing "their product" on questions and issues with their diy inverters which are rebranded SNRE inverters. If you're going to put your name on rebranded products you better have made it better and be able to describe how and why; you should also know the product before releasing it! Instead of just rebranding this foreign stuff why don't USA companies issue their own designs and or modifications and have them build the product for you specifically? Midnight gave this long excuse about how hard it is to build stuff here so they have to go overseas. I get it..our government is compromised; you still could have engineers here design it with better quality guts for more reliability, higher power, better surge etc. Then know your products instead of expecting the diy community to figure it out! Get out front and have a beta test community before releasing stuff. Solark has figured this out, still made in china but they took it from made in china junk to made in china decent. There issue is they got way to arrogant on how awesome they think there product is worth which is why they need a serious competitor in the AIO market.

 

[ToBeSolar]

same 22.5 max ISC, so you're safe with 2 strings

no combiner box needed if 2 strings or 1, you can just use a splitter branch for $8

Could you please spell this out for me to understand completely?
What is the max amp's on Each PV input and What is the max Voltage per PV input?
The manual reads the amps to be 18 per PV input and the voltage 500. It does not read the voltage as per input.
The manual leaves a lot to be desired. Would you elaborate on this?
I called SS on this, they said let me ask someone else, then he came back with the answer of 9 amps per PV input due to the two mppt's are in Parallel inside the unit. And not sure of voltage input.
And that's why I am confused of what is what.

The objective of business is to make profits. Designing, engineering, testing, and getting UL Listing on new inverters in the US is a multi-million $ expenditure. With the razor-thin margins EG4 is selling them at to compete, how many decades will it take to recoup that investment? You're asking a lot, it's an unreasonable expectation in 2022. That's an expectation from 1990!

Ok, I think I have a definitive answer for you. Video link below is EG4 rep and sig solar rep describing EG4 6500. Go to the 6:15 mark in the video and rep says EACH PV input will accept 500v. Which confirms my lack of fault error 11 running 370v on each PV input

I'm sure someone here knows. I'll be the first to admit I don't know every single small detail on these units personally - that's why I have a team of people I work with on every issue and product. If I knew it all I'd probably be a billionaire somewhere. Most of the guys who do know more than me (there's a lot of them) may not feel comfortable being on a public forum but I do so I'm the guy ya'll get to talk to. But it's not just me answering these questions and finding solutions - I am all over the place talking to people and always learning more.
