Is it DIY? I know a lot of the non-DIY kits require you to do stuff with the freon or whatever chemical and it has to be pressurized right which means you need another kit to do that. edit: I read the link and it is DIY .... so cool ...

Sorry, I was searching for the right words and made that mistake in the title.

I'm looking into buying this unit since its has the split phase with L1 and L2 without needing a parallel box. Are people still buying this despite the 155w idle draw? Any better models?

So, my options are to get a 220/240v inverter with a transformer that splits the phase or get an inverter like This that already splits the phase, or get a 120v inverter that can be put in parallel and buy 2 of those.

I did what you wanted to do, but the wrong way, at least in terms of knowing how to match components together. I tried doing 8 panels, and AIO and a 48v 50AH battery. I overpayed for the panels (amazon) and will eventually have to use better and different panels. I choose an inverter that was...

I agree. I think I was too eager to play with the panels and just didn't know enough so I made purchases without having enough information. Better to buy what I need in the long run then buy twice. I'll use what I have for now in terms of panels and when I get to the point that I need more...

Already found 300w panels for $50, thanks again!

The inverter does have a utility input and output but it sounds like I'm still running a risk? Or I could get an auto-transformer so that the inverter can supply l1 and l2?

Thanks for that! That's what I had thought and understood but with my growing awareness of how much I don't know I thought to ask in case I was wrong. Thanks again.

Had to run that through my head twice, but I get it. At 12awg, a 15A breaker should protect it from bursting in flames.

This one. Sorry I pasted the wrong link somehow and I'll take a look at the video asap.

I've been looking at four models of inverters and their manuals but only one states that the PV array can handle 27A, the others don't. At least not that I can see. Is there a way to determine how many strings you can use on one inverter?

It's a lifepo 50v/48v 50AH, it hadn't been connected to anything in about a month and I neglected to measure it before connecting it to the AIO. It's supposed to have a BMS to protect from overcharge and over discharge. But the AIO reads the voltage at 10v, and climbing but never higher than...

Before I start fiddling I thought I'd ask questions and figure things out first, unlike last time. I bought the Sungoldpower TP6048 and man is it heavy! I wanted to ask advice on what settings for the battery would be best. I currently have a lifepo4 48V 50AH battery, just one for now and...

It's been a tough life lesson about measure twice and cut once. I should have done more planning but now I'm trying to play catchup with myself as I go. The battery is just to hold over the equipment over night when the panels can't be used but the grid will be used when the battery is...

So, in four of the manuals that I've read for off grid AIOs, each one recommends a battery size of 200ah, 250ah, or 300ah. Is that what is required to use the AIO safely, is it a marketing tactic or just the amperage that most people use when designing their solar system?

I am a noob. But I think at 40-45 panels of 400w each you'll see much more than 16-18kW. Unless you mean 16-18kW per hour?

I have an off-the-grid DIY solar panel kit that has one 120 volt line leading into the subpanel in my garage. Before I install the solar panel there were two 120 volt lines coming in from the house I removed both lines and connected the line from the solar panel inverter to the subpanel box but...

I was wrong and you're right, they're actually the eco-worthy but the manual states 22.8

It's This battery that's 48v 50AH, but the specs say it goes past 48v, I've seen it go up to 55v if the lcd read out on my current inverter is to be believed. However, the inverter that I'm planning on buying says that it draws 127Amps on average, which is why they recommend 150A if that's to...

I was looking at a slightly different model where the manual said 150v and this model seemed to have the same manual, but I should confirm that before I make any decisions. I don't get -25c at least not normally. I'm sorry, but where did you get the 80 from? Was I correct that in order to...

The external charger seems to have worked. It charges the battery to 53.6v and said it was full. I plugged it in and the inverter was able to turn on. The support guy had me set the discharge stop at 46v and the dc low cut off at 44v. Could those be too low and so when the battery was at 48v...

Thanks for the heads up ... one way to find out and hope for the best!

I wanted to circle round back to this. I bought the dihool 160A but I'm not sure where it's supposed to be mounted but it feels like I'm Jerry rigging it by getting 4-5 inch screws to put it onto the wall without a housing. Is there a way I should attach it to the wall? Kinda feels like I...

The middle of this story is that I bought a 120v AIO when I needed a 240v split phase before better understanding what I was doing and what I needed. So, thank you to everyone who has patiently answered my questions and thanks to everyone who asked questions before me. It looks like I'm going...

I'll rephrase. I didn't see any that it would fit inside natively. But if you're saying you found boxes that this breaker would fit in I'll definitely check again.

I'm going to make fun of every single person who ever said you don't need math in school! With 8 370w in the series it comes to 404.8v VOC @ -20c, so I'd probably be only able to use 7. 4 195w panels at -20c the VOC comes to 104.8. Sizing 7 370w panels at -20c VOC is .54.2, so that goes over...

Good points. I have this so I'll use the dihool, I just didn't expect it to be this large. I think I'll have to use toggle anchors even though the wall is wood, just to be safe. I didn't see any project boxes to put this in on Amazon. Any particular specifications? It came with a 3-4 inch...

Alright, I'll have to purchase something to charge it without the inverter.

I wish I was. I didn't know about that until I researched it just now. Any chance there's a simple way of doing that?
