Hey thanks, that does seem like a lot less power consumption, nearly 1/3 in fact. A few more bucks but probably worth it to me. Thank you!

I had a 12v system before on a sailboat and I think in that place it wasn't so bad. Distances were relatively short and the system was small. It was also ~15 years ago when 24v was fancy, 36 edge case, and 48 was something that you'd occasionally hear about. But on a terrestrial system of any...

(edit: original post below but I had a terrible time with this seller, would *not* recommend!) I was on the hunt for one of these to match with my growatt that outputs 240v, and it looks like over the last few weeks everyone has sold out of them. SignatureSolar has a growatt unit but it has the...

Could you tell me what kind of 3 way valve is between your electric heater and the Navi? I'm familiar with manual three way valves but the way you described it sounds automatic. I checked out that Navi and it looks awesome. Edit: Looks like a 3 way diverter valve. I snapped a shot from my text...

Hate to be daft, but do I need to care about any of this in an entirely off grid system with zero grid involvement?

Sure, but that's a separate discussion from the grounding / bonding drama.

Hey thanks a lot, I re-read your post a few times and I think I get it. I was over complicating it a bit and your idea makes a lot more sense. Thanks again!

So I'm on the verge of spending a pile of money on a well. I'm prepared for that, financially if not mentally, but the part that's screwing with me is how to keep the water from freezing. I've always been trying to pump to a cistern higher than the home pad and rely at least a bit on gravity...

I had a terrible time with the seller I linked, wouldn't recommend that at all!

I'm very late to this party but have always liked David Poz. I didn't, and I don't think anyone who's going to dump ~10k on an electrical system should, listen to one guy on youtube. I was going to do the solark but ultimately went with stacked growatts because that's all I really need. I'd...

Oh that looks terrific, and it says it's for "48v battery systems" so I'm assuming it can handle charging voltages a bit above that.

I wanted to offer a small counter point in some circumstances. I live in a somewhat cold place where we get a few sub zero (f) nights, nearly all of winter is lows below freezing, and we get ~20 feet of snow on average. When it's snowy you'll bring that snow inside on your boots and your...

Pretty much the title. I have a 120v Lincoln LE31MP and I use it a lot. I have a lot of batteries and a lot of panels, completely offgrid. I'm looking at a Sol-Ark or the eg4 version as an upgrade, but want to make sure I can run my welder with it. Thanks so much!

Just to be clear, this is for people who bought batteries recently as well? I have a few batteries on order from you right now but I put the order in a few days before the discount on the chargers. I'd like to get that, I can just use my account and it will figure it out in the shopping cart...

We're standing up a new array and I'm building a simple box/cabinet out of 1/2" plywood to house some items that will be at the array. Right now I've got: AIMS disconnect. Two identical 6 panel strings going into that, each string going into one input side. Parallel cables, taking the string...

Hey there! I'm looking for some new all-in-one boxes and I thinking about the LV6548V. My array is 360v and 4080 watts but the LV6548V says its maximum PV wattage is 4kw. Does it matter that I'm 80 watts over? Will it hurt the unit or just only allow 4kw through? I'm fine losing the 80 watts.

Awesome, thanks man.

I'm not sure, but I like their build quality and approach. I haven't seen a lot of independent views of their products from trusted sources so I know I'll be taking a bit of a risk. My own experience with wind is that it needs to be in a very high location, double the height of anything on the...

I haven't talked to them, I got my growatt from someone else as signaturesolar.com is out of stock at the moment. But I did get my gyll batteries from them, so hopefully no funny business there.

Hey there! Curious about the configuration for smart load when you parallel / stack EG4 18k units. As in, if you have two units in parallel now you have two smart load ports. Do you only use one of the units for wiring or can each unit be configured separately? IE: unit A has X parameters and...

Just talked to a guy over there, got all squared away, thanks so much!

Isn't that because of the possibility of running low voltage? At 340v DC or 240v AC there's no reason to run big wires like that. Edit: yep, in the documentation it says pretty clearly to use the right size wires for the power you'll be providing.

We're putting an 80 gallon hybrid / heat pump tank in but I'd like to also have a propane instant heater that can kick on if needed. I've heard some instant heaters can and can't handle pre-warmed water. Does anyone have a recommendation on some manufacturers / models that would do a good job of...

So I'm not nearly as up to speed as you all on this, but am curious. I really want an all-in-one-inverter for my offgrid world. And I really like the smart load concept that both the EG and SolARK will do (when 90% charge and keeping up with loads, divert the excess solar somewhere else). I got...

My PV array is putting out ~240v and I need to connect the array's output to some large underground cables. Typically I'd use terminal posts to do that and put lug fittings on the solar output and lugs on the big cables, and connect them with the fasteners at the posts. The problem I have is...

Hello all, first time poster long time lurker. I have some experience with small solar systems but this is my first time building something larger and bigger. It's going to run a ranch style property (all offgrid). I'm trying to wrap my head around the legs/phases wiring that I've seen you...

Sorry to be another one of the DC breaker questions and I reviewed the documentation that I could find, but a really basic problem is jumping out at me here. Pictures below. So (when in the "on" position) the bottom left (++) is chained all the way to the bottom right (--). In fact when I ran a...

Thanks. Unfortunately my underground cables are 4/0 (huge, like the size of my thumb) hence why I was trying to put lugs on the ends and hook them into posts. It's just really hard for me to understand how 10 gauge wire is capable of supporting up to ~500v dc but these huge terminal bolts are not.
