RuiXU battery experiences

It will take a few cycles for all cells to balance...
just an update..

I have 19.2 kWh of Ruixu packs in a backyard workshop I am still building and a single MLP 6500 ( = MPP LV6548)

The weather is crummy and I am still finishing the electrical/insulation/drywall so for not the equipment is on idle with only some lights now and then.

I can confirm that the Ruixu cannot detect the idle current draw of the inverter and solar assistant so the SOC never drops. Just something to watch out for. It hit 50V then started tanking while still reporting 98%. It just sat for 13 days on idle. If you are using it and pulling more than 50W continuously you will be fine..

Also I note that the close communication with the inverter works under LI-b protocol but the BMS is requesting a bulk charge and float voltage of 54.6V.... the ruixu manual says charge voltage should be 56V so not sure if the BMS is configured wrong.
 
I just put my Ruixu batteries in production as a UPS for my critical loads with 2 X 6000XP’s.

Pretty happy so far!

Just ordered 4 Ruixu batteries with server rack. no shipping cost, no tax, 10% discount brings price below what I paid for 4 EG4 batteries without rack, 18 months ago, not to mention $400. plus, shipping, from S.S. . No ETA yet, but they need an outdoor enclosure to be built first anyway. 10% discount till end of February [edit]

Hello,

Is anyone else using the Ruixu packs with Solar Assistant? I can only get the stack metrics to show up but temp is not there. I was hoping to have the data for each pack in the stack but maybe that information isn't shared over the LI-b protocol.
 
It’s not on the 6000XP battery compatibility list, but communicates when on L-ion type 6.

@Rachel Wang-RUIXU any idea when it gets on this list?

It may be a little difficult, except Pylontech on the list, other companies have business cooperation with Luxpower.

But that doesn't matter, it's okay to use either the lithium-1 or lithium-6 protocol.

The LI-b protocol contains temperature information

ok thanks,

I would imagine that Solar Assistant has to add this capability to their "Voltronic LI-b" protocol driver... right now all we get on the battery details are total Capacity, power, current, voltage and max current details. It does not split out details for each pack.

Their EG4 battery metrics are massively more detailed than this. I hope they can improve this are Ruixu-type packs become more popular but my interactions with Solar Assistant team are unfortunately not inspiring.

Our warehouse located California,stock is available in California warehouse now.Batteries will be shipped from California warehouse to your address.
We use Roadrunner,Fedex,Central transport and so on. any questions,freely let us know at any time.
Can local customers pickup from your Rancho Cucamonga warehouse?

Can you make custom length cables? Im considering 2 Rx-LFP48100 for an RV installation where each unit will be side-by-side in parallel for 48v x 200ah total.

What is the recommended air gap around each unit for heat dissipation?

Thank you,

Brian
 
Looking for the "state of charge" of the Ruixu batteries when they were delivered.
If anyone measured them before they charged them it would be helpful.

when I got mine it stated 48% on the indicators but only took 3kWh to charge fully (54.6V) as per spec... Which you make it actually closer to ~38%... (1.8/4.8).

now that I have the batteries , I need 20ft. of rs485 communications cable to reach inverters. Does anyone know where to buy it? looked on amazon and ebay, no luck.
 
Thank you, found it easily on amazon. why is it called RS in some places, and RJ in other places?
RJ45 is the connection type I believe and RS485 is the communication standard.

Somewhere in the manual I read about the max length of the communication cable before signal is degraded.. Don't recall at the moment.
 
Perhaps a standard international fee your credit card company charges?
No doubt. I just wasn't expecting it because they have an office in LA. I guess when you place the order it goes outside the US and they give it to their office in the US or wherever.
