RuiXU battery experiences

Buying the 10-rack with 5 batteries may be the way to start off. I'm certainly happy with the 10-rack, but well - it's a lot of battery.

Granted that it's certainly better to have too much battery than too little,

In Atlanta right now in June I'm having trouble charging it. I often see people say "My batteries are full by noon", and that certainly isn't the case for me.

I do charge the battery with inexpensive overnight power, to 40%. When we wake up, morning Air Conditioning use typically pulls it down to 35%. Then solar slowly comes alive, and by 3:30pm the SOC is typically 85%, but then the Air Conditioners are really working hard and the SOC starts declining.

My System specs are :
Sol-Ark 15K
10.9 KW of REC Alpha Pure 2 420 panels.

Advantage of the current approach: Since the batteries never get to 100%, I can store all the PV power, and never waste any.
Disadvantage of the current approach: Since the batteries never get to 100%, they don't top-balance.

[I do not get credit for any Grid-sell, so that's waste].

I'm thinking I'll charge them to 100% once a month just to balance them.
Longer term I may need to add a few more panels. We'll see what happens when it cools off and there's less AC.
 
I think, at a minimum, you need enough panel to generate your maximum total daily kwh usage on your heaviest use day, on a your best solar day. I'd go with more panels as soon as possible.

Covering all of the load was never a goal because of low TOU rates overnight.

But yeah, we did design for expansion.
 
Well, a few posts up from here I asked if everyone was still happy. I ordered, received, installed... and I too am very happy with the 10-rack Ruixu battery rack.

It shipped Fedex freight, arrived in suburban Atlanta in about a week. VERY HEAVY. Very fortunate that my basement had a side-door, so I could wheel everything around on a handcard, one at a time. The 10-rack cabinet is very difficult to move around.

When loaded, the cabinet is very heavy. It's on wheels, but they move very slowly from the very heavy weight. However, the cabinet is well-built, and strong. Assembly is... challenging because the batteries are each very heavy.

Funny story, this is my first time working with server-rack batteries. Previously when watching Youtubers like Will using the hydraulic lift table with these batteries, I'd dismiss the youtuber as clearly not very strong... those batteries can't possibly be that heavy....? Well, it turns out they are that heavy, and a hydraulic lift table would have been helpful. Or a strong pair of teenagers. But I'm 50 years old, so I nominated my wife to help. We got it done, two people to lift each battery. Server-rack batteries are heavy.

Anyways, the cabinet is great. No concerns, even loaded with 10 batteries.

For safety, I added a 200-amp MRBF to every cell, and added a 350a class-T fuse to the entire rack.

It integrated to the Sol-Ark 15K easily. Closed-loop communications works great. So far, charging-wise, with 10kw of solar, I'm raising the SOC from 30% -> 70% each day, in Atlanta in June, while also running two 3-ton Air-conditioners. Wired with a single 4/0 cable to the Sol-Ark, with a Homegrid Bus-Bar on the inverter terminals.

For Testing I charged to 100%, then turned off my solar at midnight. I then ran a normal day with my 2 3-ton air-conditioners, normal living, normal lights, even ran the electric clothes dryer once. At 11:15pm SOC hit 20%, and I enabled overnight charging. So far I haven't yet taken it below 20% SOC.

Is it still recommended to test batteries all the way to Zero? I'm too timid right now.
What size RBF to every cell did you install?
Thanks

Many thanks for your support. regarding the SOC,pls download our new firmware (LD14 FIRMWARE) here:1. The forced charging threshold has been modified (changed from 20% to 10%) 2. the SRNE inverter (WOW) communication protocol has been added. anything we can help,pls contact us at any time. https://www.ruixubattery.com/forum/download/ld14-firmware
 
Has anyone had experience connecting Ruixu batteries to Schneider's InsightHome / XW Pro?

I have not, but found a link on their site how to
they also have document here at the bottom of the above link
 
I'm also considering trying a couple of these. Don't need a rack as I have several heavy duty 19" cabinets.

My main concern is warranty and difficulty of getting in touch with support.

It's also not clear if each battery comes with interconnect cables or if those have to be purchased separately and what those model numbers would be.

I'm in AZ, any recommendations on best price/shipping out there?

Thanks.

Standard Included
(1) RUiXU 48V Server Rack battery (RX-LFP48100)
(1) RJ45/CAT5e Patch Cables
(1) Ground Cable
(1) Set of Parallel 4AWG Cables per battery

I am not sure what the advantage of the Ruixu battery is over the SunGoldPower SGP48100P. The SGP48100P uses a PACE BMS which makes monitoring with third party software such as Solar Assistant much easier. A number of folks on this forum own SGP48100P batteries. Research and decide.

It's the BUS BARS that make the factory cabinet nice. I wish I'd gotten the tall one.
 
I'm about ready to give up on RUiXU, I can't get a proper answer from anyone, not RUiXU themselves or renewableoutdoors sales.
No one can confirm what is in the box 100% with these batteries or what I would need to order separately.

I don't need their cab since I have some of my own.
However, trying to order is a bit confusing so far.

Info on the RUiXU and renewableoutdoors sites lists what comes with each battery but my config is a bit different.

>1.6 slot cabinet installation, 300MM cable (battery to cabinet busbar) included.
These seem to have the RUiXU connectors on them but I would need terminals to connect to my Growatt.
Cannot seem to find such cables.

And,
>2.No busbar connection, 250MM cable (battery to battery) included,only available for 48V system 2000W-5000W.
This means I would have to order a set of interconnect cables.

I was wondering why my questions were taking so long also, yesterday AM got a response from lead/main contact over there she'd been on holiday.
My cabinet came with a lot of mounting parts but from the cabinets bus bar to inverter I had to make my own 0/2 to the inverters battery connection. If your not using their cabinet you'd have to get those special connectors at the battery end and make your own from battery to inverter/combiner.
Not sure I follow #2 if your not using their cabinet, does your cabinets have a bus bar?
 
It's really hard to get good info from sellers but I think I've got it now and your post HardYakka seems to confirm it.
Correct, that is not mentioned anywhere that you'd have to make your own so they are assuming you're buying their cabinet.

I think the box comes with one set of interconnect cables, to connect to another battery so done on that part.
I think it also comes with one set of longer cables, to connect from their bus bar to an inverter using the same connections, presumably, RUiXU.
This is all that's needed for anyone using their special connectors from one end to the other.

For anyone else needing their special connector to terminals cables;
It is not clear if this package comes with those three cables or how long they are so yet again, would have to ask for clarity but sales is not very helpful either RUiXU or resellers so far.

In my case, I would use the interconnect cables that come with the battery but would have to cut the ends off to put my own terminals on them to connect to my own (terminal) bus bar.

From my bus bar, I have to make 2awg cables with terminals at both ends to go to inverter.

I just received and installed a set. (I bought their cabinet as well.) But, you should be able to use the cables that come with the battery to connect to any busbar. The special plug is only on the battery side. The other is a regular terminal to fit an M8 bolt. Just make sure to order them for the rack mounted set up, not the battery to battery set up.

I just received a set of 6 Ruixu heated server rack batteries with the cabinet. Shipped on time and packaged very well as others have mentioned. Install and setup was a breeze. Replaced a lead acid bank. I'm running victron Quattro 10kva, mppt 250-100 and a cerbo gx with a 500a smart shunt. I used the victron cable purchased from Ruixu and the system instantly recognized the BMS and let it drive. Overall I'm very pleased.

I do have a couple questions though. I set the voltages for the quattro and mppt as recommended in the battery manual (56 absorbtion and 54.6 float). But when I look in the remote console under the battery>parameters it shows the charge voltage limit as 54.6. Watching the charging pattern the last two days, the bms took the charge up to 54.6 and then went to float. I thought it should go up to 56 to top balance and then drop to float. But, I am new to LiFePo, so not sure if I am carrying my lead acid thought process somewhere I shouldn't. Is this something I need to correct? or is it good to go?

Currently the lowest cell voltage is 3.316 and the highest is 3.325. Is that close enough to balanced? or do we want a much smaller delta there?

I am guessing (from previous threads) step one is a firmware update. I just tried connecting a pc using a victron MK3-usb and an rs485 cable using Ruixu's tool, but it didn't recognize the bms. I ordered a usb-rs485 cable from amazon and will try again when that gets here. I saw on the Ruixu website the last firmware listed was 18...but the one that said heated model was like v10 or so.

Thanks for any insight.

Initially I thought there were issues with two of the RUIXU's bought late spring but it was only the firmware version. Once I brought them all up to LD18 no LED/SOC issues.
But ... I'm getting the same charging problem, RUIXU said to charge them up but the 6000XP will not go past 54.6 even if I run the 20KW generator for an extra hour. We are really OFFGRID, no grid connection. Then there is no 'on demand' charging, no generator start time... EG4 fails IMHO after Magnums for 25+years, luckily I have 2 new 4448PAE in boxes that I didn't install, after this inspection those 2 XP's can go to outbuildings. But Magnum has shut production, and so it goes.

I set the GEN setting to 7kw.
Now Saturday whilst commissioning the Pioneer HVAC (3 head 36kbtu) we ran the generator and supplied power to unit via 6000XP. It cranked up to 5.1kw house supply so I know the gen is capable and still supplied charging to battery, around 1.1kw. Running back and forth to HVAC so forgot to take a picture.

Another 'unique' feature I stumbled across. Accidentally left battery type (Li) to 12, not 6 and I saw 3.43kw going to batteries.

Ran the HVAC's largest head (24K) overnight set at 62F/16.6C as temps were below 32F/0 and to see battery draw down from 87% to 66% (6 pak of server rack batteries) farthest room in house was 62. RUIXU's looked good, tried to charge after getting powerhouse up to 40+ and could only see 2.12 max.

Have you tried changing the charge voltage limit in the BMS? I think that is the issue with mine, but I don't have the cable to connect my pc to the batteries. I can only view thru my Cerbo GX. The charge profiles on my Quattro and MPPT are set to 56 but the BMS is overriding and telling them to shut down at 54.6. Prior to hitting 54.6 they are taking all the juice the system can provide, up to 100a +or - when my MPPT is maxxed.

No I haven't based on what the magical inverter displayed yesterday, lower right hand corner. Repurposed an ole Dell yesterday, cleaning up the disks and taking it to Power House to become a dedicated inverter/battery display. I have the Magnum network unit so once I make the switch I'll still have monitoring. In all these years what the simple Magnum displays is just fine.

If I have time tomorrow I'll hook up the laptop and see if I can locate them using the RUIXU tools.
Thanks for suggestion

Because the interface specifications of different inverters may vary,you can obtain the cables between the battery and the inverter as follows:purchase our S30,or S80,or S200 cables(only differing in length).These cables are 4 AWG and suitable for various inverters,
https://www.ruixubattery.com/product-page/4awg-2000mm-pure-copper-battery-cables-black-and-red.If these cables are not compatible with your inverter interface,you can purchase cables with ring terminals on both ends that are compatibie with your inverter and DIY connect them with our S30/S80/S200 cables.
