Hey, you're getting pretty good at this KZbin stuff! Great video as usual. I'm with you on being excited about the direction things seem to be going. I think there's going to be some good stuff coming down the pipeline this year. Definitely going to be some upgrades in my future. Looking at this setup, I can see a number of use cases for standalone setup in remote buildings, water well, etc., not to mention it would be a great way for anyone to get going with solar without breaking the bank. Thanks!

[@Upliftyourbrothers]

Power companies going to start sweating here soon. These options are making off grid in the suburbs an actual thing.

[@GavinStoneDIY]

Exactly. While utility prices rise. Solar prices are dropping. And that’s not even taking into account the tax credit.

[@joesmith6972]

Great video, Gavin. Should there should be some sort of non-conductive material between the cells and the metal cover? Seems like it wouldn't be hard to bump the cover with something (especially in a garage installation) and making contact with the cells. Which wouldn't be good.

[@GavinStoneDIY]

Yeah it’s domed off quite a bit. But I know what you’re saying.

[@SawtoothWild]

Hey I have one EG4-LL-S 48V battery, can I get one of these and connect it to the system with full communication and not risk having the one LL-S battery constantly be the first to discharge?

[@GavinStoneDIY]

Yeah you should be good to go. They stay balanced. I have the pro battery set to the master and my LL’s behind it.

[@prepsolar787]

awesome video. I agree with you the industry is making it simpler for us diy

[@GavinStoneDIY]

Yeah things have changed so much just in the last couple years. Really nice stuff available now.

[@donbrenczeizinger6571]

Good job on the video!

[@mattpurgason2371]

What are the options for connecting a chargeverter to the battery?

[@GavinStoneDIY]

That’s a good question. I was just talking about that with someone else. I’m going to check on that and see.

[@danmccoy6164]

Other than the cabinet not being sealed. Is there any difference between the batteries. Are the specs the same. Output. Input. Being able to remotw start your generator ect. Exactly the same.

[@GavinStoneDIY]

The battery specs are basically the same besides being indoor rated. All the same amperage numbers. As far as remote start are we referring to the inverter? Yeah that has dry contacts for remote starting

[@danmccoy6164]

Sorry I just got off work 12hr shift. Got my wires crossed. With the 18k inverter. 😂

[@rudycastillo4150]

I wonder whats better tesla powerwall 3 or these batteries

[@GavinStoneDIY]

These are still less expensive I believe. And it’s the same chemistry.

[@rudycastillo4150]

@@GavinStoneDIY that's true , we thinking of have Tesla 3 powerwalls 3 installed for 26k but I'm wondering if the eg4 is a better choice

[@GavinStoneDIY]

@@rudycastillo4150 from what I’ve heard there’s more user controlled options on the EG4. But I haven’t tested a Tesla power wall to really compare the two. The Tesla’s sure look cool.

[@og6537]

You can get 3 rack batteries for $999 each with 100amp bms for 300 total and they ship out the same week…

[@GavinStoneDIY]

These batteries will ship soon without issue also. Which brand batteries are referring to?

[@AdamDeLay07]

Slick! Cheaper if you wanted to put the battery in a barn but still needed the cells to stay warm in the winter....hmm...

[@GavinStoneDIY]

Exactly!

[@martyhanson1902]

I think the batteries have built in heaters

[@sspyder181]

At about 200 bucks a kwh its really coming down. Been building 14.3kwh packs at 2200.00 my cost. Almost not worth it anymore!

[@GavinStoneDIY]

Especially with the wire busbars and heaters.

[@unionse7en]

unless maybe the individual cell prices drop too, but yes right now it's tough to decide build or buy for larger systems.

[@unionse7en]

Other advantage for some of us is the prebuilt are UL9540 as an ESS

[@Roll2Videos]

Nice setup! Battery looks amazing

[@GavinStoneDIY]

Thanks man

[@frankenstake]

This is a helpful video, thank you! Figure 3 of the EG4 instructions show the wiring diagram to connect 3 batteries to one inverter. It uses the center battery to connect to inverter. Do you think it's ok to use one of the end batteries to run to the inverter? I cannot locate batteries directly under inverter so using the center battery will mean long cable runs.

[@GavinStoneDIY]

You’d have slightly more resistance to the final battery. Which is one reason why they recommend you connect them to a central point. Whether that will make a huge difference? It’s to say really. I would probably do it.

[@GhitaA]

How does this compare to powerwall 3? The price difference is HUGE!

[@GavinStoneDIY]

I haven’t researched those Tesla systems much. I know it’s hard to beat these new eg4 systems for the price. Lots of power and expandable for a good price.

[@prepsolar787]

I have a question if I was going to install two 5kwh lithium batteries using busbar should I use 2/0 awg cable from the busbars to the inverter 600xp?

[@GavinStoneDIY]

Anywhere from 1 awg-2/0 cable is fine. All of those can handle the amperage.

[@prepsolar787]

@GavinStoneDIY ok thanks

[@SolarinStarke-kt2lm]

Wow you have really had all types of battery and inverter inventory. Did you connect your DIY batteries to your 6000xp or 18kPV?

[@GavinStoneDIY]

To the 18kpv yes. They worked great in open loop.

[@joetripp123]

Hey Gavin. I like this new PowerPro budget model. I have a little buyers remorse with buying LLs , but I like having redundancy in the battery area. If I was to set up a system for my parents or a friend it would be a 6000XP and the budget PP battery. Very nice looking setup, easy to install, and a good sized system. Two thumbs up EG4. I'm confused about the firmware statements so I'll rewatch the video. Was this new battery firmware? What version? I've not updated either the battery or inverter firmware on my 2 month old setup, seems a little intimidating.

[@GavinStoneDIY]

It’s the newer version of firmware they released on the batteries about a month ago. They have a walkthrough guide on the firmware to tell you exactly how to upload it on to the batteries. The good news is you’ll only have to do it once.

[@0900McShizzle]

I have a Victron system comprised of 2 multiplus II inverters in parallel and a charge controller, can I wire these directly to the bus bar and skip out on using the distributor? They’ll be fused of course, I just don’t see the point of having the distributor

[@GavinStoneDIY]

I would think so. The distributor helps for people that have different battery types amongst other things I guess. These would communicate directly with the Victron system.

[@enwinn]

What is the measurement from bottom of battery case to top and bottom of case to floor (e.g. length of feet)? Specs show a height of 36.4 in. Does that include the length of the feet?

[@GavinStoneDIY]

That includes the feet screwed all the way down. They do have adjustment so it would be a bit higher if you use them for leveling

[@ericjansen9042]

Great video, sir! Most informative of the ones that I've seen so far. In doing a poll though, I think the community has spoken, and they want to see the fire suppression system get tested. ;)

[@GavinStoneDIY]

Let me get my torch. 🔥

[@unionse7en]

can the all weather version and the indoor communicate to the 18pv together?

[@GavinStoneDIY]

Yes. They can communicate with each other without any issues.

[@dangoras9152]

Hey brother can u have 3 of those batteries hooked up to one 6000xp

[@GavinStoneDIY]

Yes. You could have as many as you like. But they are designed to hook 3 at a time to an inverter. Without using an extra busbar. If you follow the link, the manual will show different options for hooking them up. Honestly with one 6000 xp you could use the internal busbars and hook more then 3 at a time pretty easily.

[@dbarnclay]

Hey Gavin, Great video. Nearly answered all my questions about combining a rack of 6 Lifepower4 Batteries with the one Powerpro I received with my 18K upgrade from the 2 6500's. Do you know if the software will track both to the 18K? I know the Lifepowers can only handle max charge and discharge of 100 amps and the Powerpro is 200A. I was thinking of limiting the charge current to 120A over all of the batteries to protect the Lifepower4 and link them all via the powerpro busbar. Would also fuse the rack with a 200A fuse. Plan to talk to the Techs when I commision the system but would like so advice as I set it all up. Thanks

[@GavinStoneDIY]

So I don’t think there’s an official firmware out yet for combining the lifepowrs with the pro batteries. Not only is it different Ah rating but a different BMS. So at the moment I don’t think you you’d get the same closed loop readings I showed here. At least not with both types of batteries in it.

[@dbarnclay]

Thanks! I sent a similar question to the EG4 techs and see what they have to say. I have also considered purchasing a single 6000xp for the powerpro and running it as in as a generator to the 18K, but does the 18K have to deplete the rack battery 1st before it shifts to the 6000xp/Powerpro power, then finally to utility? So many questions. Thanks for your thoughts on it.@@GavinStoneDIY

[@joetripp123]

@@dbarnclay There's a setting in the 6000XP for "Generator charge start battery SOC%". There's also an end battery SOC%. I'd guess the 18k has something similar. So just set it to whatever % you want it to trigger the 6000XP to start/end feeding the 18k.

[@sjbill1793]

Another great video. Thank you for all you do in this solar space. I was wondering if you could maybe do a video on connecting an external generator to the 6000xp for battery charging and how to get the right settings for the particular generator. Again thanks

[@GavinStoneDIY]

I may try to make a video on that. I’ve got quite a few lined up already. Personally I prefer the chargeveter for hooking the generator to. That way the inverter can keep doing what it’s doing while the batteries get charged

[@sjbill1793]

@@GavinStoneDIY Thanks. I'm kinda at a loss with how to connect the chargverter to the Power Pro battery. I appreciate your videos a lot as i'm not very bright when it comes to solar stuff.

[@GavinStoneDIY]

@@sjbill1793 I’m working on a video now about the chargeveter. Eg4 is working on an easier solution to connect them together. I’m glad my videos are helpful. I remember when I first started, I needed all the info I could get.

[@jasongoldenberg973]

The UL testing won’t allow these batteries to be placed closer than 3 feet. I would be surprised if any ahj allows that to happen with a permit.

[@GavinStoneDIY]

They mention 12” in the manual still. So it likely would pass inspection with that. It’s hard to say. Some localities are way easier to deal with than others.

[@jasongoldenberg973]

@GavinStoneDIY the UL requirement is 3 feet spacing. The manual can say whatever they want but it's not what any ahj will require. I just went through this in vegas. Also the batteries don't have a nema rating and only an ip rating which is not acceptable. Indoors those don't matter but outdoors they do.

[@GavinStoneDIY]

@@jasongoldenberg973I know quite a few people that have these at 12” or less and passed inspection. I understand what you’re saying. I’m just pointing out that can vary quite a bit depending on your location.

[@paulbaker3144]

In the desert we got the outdoor sealed PowwrPro model because the dust gets into everything even inside a shed. I hope they survive the heat inside this shed. We will have to leave the shed door open in summer.

[@GavinStoneDIY]

They do have a maximum temperature disconnect. But a fan might help them stay cooler.

[@turtle1723]

Can you add one of the solar EG4 minisplit ACs to your shed?

[@paulbaker3144]

@@GavinStoneDIY I agree. A fan will be needed. There’s should be plenty of surplus power during the day. I just helped the owner design it. It was all very rushed so no fans ordered yet.

[@jamieroland538]

can you use these in an RV?

[@GavinStoneDIY]

You could. It would just depend on the weight. Lifting them in there would be a pain.

[@javiergonzalez-us5is]

Can the battery be charging with the chargevrter while the inverter is running?

[@GavinStoneDIY]

Yes. That works just fine.

[@javiergonzalez-us5is]

Would I connect it directly in to the wall mount battery?

[@paulbaker3144]

If we have a Sunny Boy grid tie inverter and want to go off grid can be just feed the 240vac output of the Sunny Boy into the grid input terminals of the 6000xp inverter? Thanks.

[@GavinStoneDIY]

@@javiergonzalez-us5is yes you’d connect it directly to the bus bars in the wall mount battery
