Discover AES batteries are closed loop plug and play with Schneider XWPro and 600/100 MPPT.
Looking forward to the follow-up on this. Thanks!
Great review on the system. One correction to make. The Rackmount batteries in the Slimline enclosure are fully rated to UL9540 DC ESS, allowing the system to be matched with any inverter with Ul1741 SB for a fully compliant system for AHJs nationwide.
Can't wait to see the installation when it's done.
Good to see you guys lurking on these channels. I love my 4 7.4kWh AES. The plug and play closed loop SOC with Schneider is a thing of beauty.
I have 4 7.4kWh Discovery AES batteries with direct CanBus SOC control with Schneider XWPro. No Lynx hub required. 12.86kWp of ground mount solar. 2 racks of 8s2p each going into their own 600/100 MPPT. One rack 180 degrees, the other 230. Produces solar power well into PGE TOU. Can’t say enough good about those 7.4kWh AES batteries. Plug and play with Schneider. Couldn’t have been easier.
Very interesting concept. If the “remote storage and generation” becomes code everywhere, you’ll be ahed of the curve. This is also a kit you could work with discover on and provide a “pre-wired” solution. A true “land your wires and go” solution is very desirable for some clients and electricians.
As far as the new code goes, I don’t see it being easy to implement in the northern or southern 1/4 of the US. Northern US will need an insulated cabinet to keep heating of the batteries efficient, and southern US will need active cooling for the batteries.
I work with remotely located telco equipment. A large US phone/internet provider found out the hard way that even lead acid batteries don’t handle temperature extremes well long term. They were even using equipment that was “rated” for it.
Will any of those new battery codes even take affect in the country after the supreme court case limiting the ability of regulator to put in new regulation?
Thanks for taking the time to show us this new product! I like putting the SolArk 15k on the box, everything all together. I'm wondering what you were thinking about generator location. Sounds like near the inverter is best, to simplify wiring runs.
What I like about Discover is simple - 6 batteries per cabinet instead of 4. It makes the cabinet cost way more cost-effective (as customers really need about 75% of daily energy use in a battery for a good "whole home backup" experience. Combine with 2 breaker ports on a Sol-Ark 15K and that's up to 60 kwh of storage that can easily be connected. Then the outdoor aspect is very nice. How about a dust cover for the winter to help with battery heat retention.
Some clarificatios:
1) LFP by default is 1C Discharge / 0.5C Charge, newer chemistries like LMFP can do 1C/1C+ but is not readily available for ESS Usage (its all going to EV's).
2) Those Rack Mount battery packs are intended to be "upright" to that the" cell vents" are facing "up". Cells on the sides often leak and if installed on their sides, they should be in the wide flat side so the electrolytes within over the "jelly roll".
Several companies like Iron Edison, Revolt (now bankrupt due to claims & failures) and several others made by GSL (Chinese sub-contractor) had cells fail, leak electrolyte which corroded wires & electronics ad a few caused electrical fires. Unofrtunately I cannot paste Photo's of these failures... We've seen many on our forums.
CSL has since changed designs to keep cells upright as have other companies now and increasingly so.
3) LFP in Pouch Format are not dependent on Cell orientation. Same applies to LFP/LMFP Cells like BYD's Blade Cells and similar but you will not find those in ESS systems unless from the Home Company (BYD makes ESS systems with them) Note that CATL, EVE also have similar cells.
! - PLEASE - ! : Do open one of those Battery Packs, note the internal installation and how it's done especially how the cells are arranged. It "may" be possible they are not using LFP Prismatic Cells (Big Blue Blocks) (hopefully that is the case).
We have noted that it takes on average between 2-4 years of General Average duty for battery packs with cells on their sides to start leaking. It is NOT a joke or FUD it is real world experience as posted by several of our Forum Members who have suffered such issues with commercially assembled, UL Certified packs.
How much of this is a size/weight mechanical issue vs. a vent issue? Im wondering if it has more to do with the size/weight ratio of cylindrical cells on their sides specifically, or even prismatic cells on their sides specifically... or might it not apply to pouch (similar to blade as you mention)?
This is where I think Scott is a bit wrong about outdoor install - thermal expansion one way or another can't help battery issues so any form of sheltered protection like a garage should be a default if possible and adequately sized. I'd put the discover batteries inside the garage until they hit the 80 kwh mark, given that each cabinet is a DC ESS.
@@pvbatts Let's not get confused here.
Prismatic (square blue cells) have vents on their tops.
Cylindrical cells have no vents.
Pouch or CTP Type cells like the BYD-Blades are also different.
Take 16 LFP Prismatic cells (100AH cell weigh 2kg, ea.)
Stack them all up and the bottom cell has to carry the weight of the 17 cells above it. That's 34kg pressure on the bottom cell. EXCLUDING any Compression/"Fixing" pressure which may be applied.
The most common configuration is 8 cells per row with 2 rows. So effectively the weight of 7 cells per 1 "bottom" cell.
CAN'T PUT LINKS or Photo's here... Grrr.
Thermal Expansion & Contraction is a constant with prismatics as they go through their cycles. Of course this is affected not only by Temps (ambient & Internal to cell) but also the charging level (volts/amps).
Where I live, we see -35C/-31F to 40C/104F. Would I put an LFP system outside even with heated packs ? NO ! 1 OOPS can make for a very bad day ! or more !! I have a heated powerhouse that keeps everything at 15C/59F and all the packs in parallel are very happy with that.
I have been working with LFP for a long time and have assorted involvements with manufacturers & suppliers. Gosh have I seen "things" over the years to raise eyebrows to new heights. Ironically a few really Very Obvious stupid Mistakes made by companies that really should know better. Shockingly & inconceivably some of that actually passed UL~ . They are now changing things up to weed that out, stand-by for 6 months. ETL has caught up on some of those issues now.
LFP is certainly nothing like the other Lithium Based chemistries YET "admin-politicals" lump all Lithium Together and treat accordingly (very stupid). Then they take "krap" from the Lead Acid days and also apply such (Batteries outside in fire proof "vaults" etc etc etc) and other nonsensical things like active venting (no hydrogen but they think so) etc...
I see no reason that they have be ostrasized and shoved outside. But proper & safe installation is critical regardless and they should not be stuffed into a closet with a pile of junk either... Unfortunately, protecting against Stupid and what it will do is a terrible task to keep up with.
People have more problems about their Inverters, AIO's or SCC's making fan noise (which can be insane) compared to anything else.
BTW: I am running 50kWh of LFP using 280AH cells - gave up on the small stuff long ago.
Funny part of all this... Top Grade Certified by manufacturers with Verification tests 105AH cells can be had for
Always something NEW! Would love to see you do a project in the Northeast! What areas do you cover, or are you all over the country?
What a fun project.
Thanks for the video! I wish you success! Ukraine.
Stopped by to see what you Discovered!
Thanks Scott
How hot can these batteries get? I live in Central Texas so outside batteries don't seem like a great idea.
He will learn quickly that stuffing that cabinet with 6 batteries is going to get toasty.
The max temp specs are in the brochure, and I think the manual has recommendations too, but these are installed in Arizona in hotter places than central TX. They also make a fan kit for the cabinet to assist with cooling.
Great idea!!👍
Love it!
Such weird code, they know Lithium Ion and LiFePO4 are radically different in safety right?
Great system.
Great looking setup! I'm interested to know how people are getting on with the Sol-Ark new system, now that the PV-PRO APP has been abandoned?
MySolArk is working for me, no real difference.
Where can see c rated on the battery or data sheet
ENGINEER 775, Thanks for sharing the debut of the Discover Outdoor Battery Rack!
We have 2 KiloVault HAB v4 7.5 kWh each at 150Ah Nominal Capacity, but our EcoSmart 11 Instant Hot Water Heaters draw is too much Amperage, so the Grid Assist in the Load.
We are looking for high amperage batteries 🔋🔋 30 kWh that can handle the load with our Sol-Ark 15k.
WHAT WOULD YOU SUGGEST?
Practical prepped power plant!
Do these batteries have heaters? If not then they really are not outdoor rated for anything north of Phoenix.
From what I see Most advise a 0.5C so you get the max amount of cycles. My EVE cells can do 3.0C if I want 3000 cycles or 0.5C if I want 8000 cycles. With my 4 battery banks I never go over 0.2C per bank. I have 280ah cells instead of the 100ah cells. Also have the better JK BMS (4 1 for each bank). So balancing works like a dream.
In using the latest JK BMS, is it compatible in communication with the Sol-Ark 15? What inverter(s) do you use? I'm looking at some larger battery systems with the newest JK BMS, but I don't want to get them and find they have communication issues.
@@tquinn63 build your own. get the JK BMS Smart Inverter. it talks to anything. I built my system on a budget. I have 2 Growatt 5kus inverters. right now you can build a 15kw battery for around $1900 for all. MB30/31 sells which have around 330ah for $1200 a case for $550 and the Inverter BMS for $160-205. The Inverter BMS is the latest and greatest. GO watch OFF-Grid Garage.
New to this Solar and battery power for a home. Up north in Michigan it seems temps would be too cold in the Winter time during certain weather cycles (Temp related) when temps get at freezing or below, so I’m assuming in Michigan you’d have to have your battery bank stored below ground, and somewhat heated, as for the rest of the season in the temps are good for this.
they always gotta mess with the codes, to always make it harder for the average joe.
I think “government” it really trying to do away with DIY projects.
No more hand crafted shitty 18650 packs
If you ever ever come to California for a install please contact me would love to give a hand
