    DLG LiFePo batteries from globalsources ?

    Has anyone tried these? I'm new to all this but price is better than EG4 for the 48V 100aH... They also say 10 year warranty and UL Cert... https://www.globalsources.com/LiFePO4-battery/LFP-Battery-Pack-1186826607p.htm

    When do I need a transformer?

    I guess all I can do is put a plan together and see what the code compliance office says... I really kinda like Growatt inverters and the eg4-LL batteries (and that they can communicated) but then none of Growatt's are UL listed yet and I'm not sure if batteries need to meet certain code...

    When do I need a transformer?

    See. I don't know the difference between listed and compliant. That's part of my issue. Because I want to build my own system at my residence, but I don't know what listings or certifications are required for each component. Being confident that I can build something and building something that...

    When do I need a transformer?

    According to the email I got from Ian at Watts247, those LV6548s that you have are the only UL listed ones they carry. Have they been pretty solid for you? What is your setup? Do you have a diagram, or can you just explain?

    Education on Certifications

    I emailed Watts247 and growatt-america asking about UL certifications for certain units. I don't know the differences in certifications and/or if UL is required for me to install these units... What I do know is that I will get a permit and have it inspected and need it to meet code...

    When do I need a transformer?

    @Lt.Dan It doesn't look like the LVX6048 is UL certified. Although I don't plan to be grid-tied, so I'll have to check with my city code inspector to see if that matters for off-grid. I should note that I didn't check UL cert for any of the other inverters discussed in this thread (it's just...

    When do I need a transformer?

    Also. Doesn't this 'split phase' mean that it supports 120v and 240v output?? https://www.amazon.com/Fencia-Inverter-Controller-Supports-Monitoring/dp/B097PJGKBH If so, I could avoid a transformer altogether and just run a 240v to the AC input. right? or no? Would it support only 1 of the two...

    When do I need a transformer?

    @Struc I've watched some David Poz but he even comments that his transformer setup is not ideal (apparently some YT commenters said something about his design), so I don't want to copy him if that is the case. Also, very good point about the switch and taking the transformer out of the...

    When do I need a transformer?

    This is kinda what I as thinking, so that SFP5000 would probably be great. I'd just need to know how to put the transformer in this diagram, and exactly how it would be wired. Plus I don't even know, at this point, if that switch that I put in the diagram is displayed correctly. What I want is...

    When do I need a transformer?

    That's odd that you can get either an inverter with dual-AC or inverter hybrid with charge controller (but then require a transformer if you want dual-AC). There probably is a hybrid unit out there that can do it all, right? But I bet it's super pricey if there is one. EDIT: Actually, does this...

    When do I need a transformer?

    These would still need charge controllers, though, right? Looks like I'd have to buy them separate.

    When do I need a transformer?

    Yes. Michigan. My house has a standard 200 amp service right now. I may overthink things at times. But I don't think that's all bad when it comes to electrical because I don't want to fry anything, or worse, burn shit down... LOL. However, if there's hybrid inverters out there that are already...

    When do I need a transformer?

    I'm just in the early planning phase. Still deciding on everything. One thing I'm still struggling with is knowing if/when I need a transformer. I'm looking at the 5kW Stackable 48V 240VAC 100A 450VDC Off-Grid Inverter by Growatt. I'm not sure how much it will matter yet, but guessing I'll be...
