Choosing the Right Home Backup Battery

[@booterone1]

I prefer the server rack batteries, as with the cabinet, makes them very easy to relocate.

[@jerrysmith5495]

Ray, I'm loving you're videos. They are all very imformative and I often seek out your new content. Keep up the good work. 👍

[@diySolarPowerFunWithRay]

Good to hear. I appreciate that. Thank you.

Great Information on Batteries this the area in what I am trying to to plane for my off grid system in the spring 2025

[@terrybrown5883]

I know I plan for 2 or 4 battery depending on the size for my Rv build

[@terrybrown5883]

I am going with 48v batteries Suggestion

[@diySolarPowerFunWithRay]

You'll love those. They also have group 24 size 48 volt batteries... if you want to go with something small and cheap

[@URackADisciprine]

RUIXIU has a 16kWh wall mount battery like the EG4 PowerPro that will be UL certified shortly (supposedly) and cost around $3K USD. Larger capacity for less money over the EG4. Not to mention, EG4 batteries have terrible BMS' in them with high failure rates. Wouldn't touch them with a ten foot pole.

[@Kaalkian]

this is an exciting product i need see a teardown asap vs powerpro. this is gonna be great year for energy diyers

[@tinysparky]

why do I keep on seeing you posting about RUIKIU, are you a sales bot for them? seen you on several channels

[@e6ensperception]

​​@@tinysparky is the Ruixu not as good as it seems? Will profuse did a vid on the same eg4 battery and he tore it apart and said its easy to short out the battery. So Ruixu seems like a better option right?

[@tinysparky]

@@e6ensperception I don't know hence I am trying to learn from all the guys, but when somebody says another brand sucks, i tend to research their comments in other areas and just saw a pattern ether from a fan boy of RUIXIU (i mean who actually capitalizes their name), or a bot for them.

[@e6ensperception]

@@tinysparky you know what thats a good point. I actually unsubbed from will prouse after I noticed a pattern of him doing videos on products he makes commission off of. He seems to choose high quality stuff but money commission is a high priority to him it seems so your point is very valid! Thank you for your perspective

[@NurseAcrobat]

To me the wall mount would be good for an outdoor install if combining with an outdoor inverter like the 18k or solark, saving all your interior garage space. I have no garage so if/when I install something like this it will probably be either on the outside of my house or along the wall of my laundry room, near my outdoor main electrical panel.

[@LesRCnmore]

I see that you have a long run from your solar panels to the batteries 🔋 my question is how thick of a wire u used? And how long is your run??? Btw your videos are awesome!

[@diySolarPowerFunWithRay]

10 gauge and 8 gauge just in case I want to have some panels in parallel. But I think I went on the thick end. the run is around 140 ft

[@Mike-01234]

There is a new battery I just saw has 9540A UL called liniotech tiny bit cheaper then power pros. It looks like they have ESS 9540A UL cert with Sol-ark probably a brand Sol-Ark has approved if you need to get it permitted. I heard even offgrid now some AHJ's are requiring 9540A ESS UL cert in California.

[@diySolarPowerFunWithRay]

That would be awesome! I'm seeing it as pending still. Similar to many other manufactures(liniotech.com/liniotech-20-kwh-lifepo4-power-reserve-power-wall-battery-storage-12-years-warranty/). But yeah, If you live an California I think it's pretty important.

[@fauxque5057]

I like to save money. Lots of money. So I buy 4-12v 100ah Batteries from Amazon with free shipping. Then hook them in series with home made bus bars made from flattened copper tubing covered in heat shrink. The last set of 4 Chins batteries I paid $932. delivered. I use 2 Harbor Freight 3 shelve rolling carts to hold them. Each shelf holds a set of 4 batteries. Currently I have 20.4kw of batteries and add to it when I see a sale on any of the Enjoybot family of batteries. Chins, Ampere Time, Redodo, or Enjoybot. They're all the same manufacturer. The only thing missing is the communication but that's nothing I need. I have balancers on each set of 4 so if I want to see voltages I go look.

[@hamadilawson4471]

Tell us more! How about some pictures or a KZbin video.

[@brucey5585]

You didn't save money.😢 if you want to save money then buy raw cell from batteryhookup. You can get 16 x 3.2v 100 ah cell for $640 then add a 48v bms for $80 then add $80 for mailing. $800 get you 5kwh setup. Also you can build a wood box for $40 or buy a harbor freight modular tool box for $40.

[@surfguy777]

​@@brucey5585agree, the cost of wiring the 4 batteries, fuses, and balancers really add up. DIY raw cells is the least costly for big battery banks.

[@URackADisciprine]

Not saving any money there at all.

[@boblupart862]

Another con is that if one section of that all in one battery fails the entire thing is dead. 6 sever rack batteries means 5 left over.

[@NeverTakeNoShortcuts]

This is the main thing. BMSs die, cells fail. Not often, but often enough i have experienced it in 3 years of having 50kwh bank

[@boblupart862]

@@NeverTakeNoShortcuts That's why I am building for redundancy. 2 6000XPS, 6 LL 48v, extra breakers if they fail. I can't realistically go 'all solar' where I am due to the power company being greedy. So I'll be taking specific rooms off grid with a generator switch/critical loads panel setup. Should be fun and if anything breaks I have a backup of the backup! Ha!

[@NeverTakeNoShortcuts]

@@boblupart862 Good thinking. The difficult thing is that a lot of these models/products go out of production and superseded by newer models pretty quickly with some of these vendors. Getting matching anything is really difficult after a couple of years. I had a SR battery go bad, and now I have a mismatched battery bank because the original battery was no longer available

[@URackADisciprine]

You will need them if you buy EG4 batteries. They have terrible BMS' in them with high failure rates.

[@boblupart862]

@@URackADisciprine I haven't seen a large number of complaints? Mine works well too. Where are you getting this info?

[@InVinoVeritas.]

Thanks for video, very informative! What do you think of Current Connected vs Signature Solar re: customer service & support from equipment purchase to post-purchase technical support? Thanks.

[@diySolarPowerFunWithRay]

I think you'll be fine with either one. I wouldn't have any concerns buying from either one of them. For tough questions, They will ask their work colleagues until they can find the answer for you. I have had more experience with signature solar but current connected seems like they have a very good support team also... they claim to have a smaller more well-trained team but I have only called them a few times.

[@brucey5585]

I would get the wall mount too but i cant get that down to my basement. 😢 heavy ass fuck.

[@joshhartin78]

Do the lifepower4 batteries fit into the Ruixu battery rack? I have been eyeing that 10 space battery rack for a while now and would really love to get it and put my lifepower4 batteries in them.

[@powerguymark]

Do the eg4 Lifepower 4 server rack batteries have fire protection?

[@diySolarPowerFunWithRay]

They do not contain any fire arrestors.

[@ob-4321]

I I have a question for you.I'm in the process of purchasing a system for my house in Puerto Rico.I like the e g 4 But I am only needing 5 kW in the beginning. And then I might step up to 8 depending. How much power I need. What inverter would you recommend? I would need a hybrid inverter. We do have a lot of outages in Puerto Rico. Thanks for getting back.Hope to hear from you soon

[@diySolarPowerFunWithRay]

Is that your your solar array size? So do you want to back feed to the grid? do you want batteries also?

[@ob-4321]

Yes too the size,and to the gid yes and I need a 🔋

[@Madsci-zy8wm]

I suggest you watch "6000xp is not UL9540 certified. YOU CANNOT LEGALLY install in the US along with solar panels" before install these batteries with an EG4 6000XP inverter in your home.

[@dawg2100]

Unless that battery cabinet under your breaker panel has wheels, that is as bad of location possible for it. Its a terrible choice to begin with and a dangerous choice at best with or without wheels.

[@kevinott-ol2ry]

I Think that I would choose the RUIXU But I don't want to buy Chinese.

[@diySolarPowerFunWithRay]

Don't the eg4 batteries also come from china? I think you're going to have a hard time finding batteries that aren't from there.

[@punksjutgbd]

That means you don't want to buy any solar equipment.

[@NeverTakeNoShortcuts]

@@punksjutgbd Yeah. The US has almost zero domestically manufactured solar equipment.

[@LifeLongLearner-om8jx]

Continue waiting until the end of time, the U.S. has no domestic manufacturing in solar or batteries at any real scale. Even the cells used in supposedly America batteries are sourced from China. That’s just reality.

[@kevinott-ol2ry]

@@diySolarPowerFunWithRay Darn, I didn't realize that they all came out of China.
