Server Rack Eco-Worthy 48v 100ah and EG4 6000xp comms.

That is why I bought two Solar Assistances. I already had the RP3B so was less than $100.

I never messed with a USB via WiFi before but that is another choice.

@jorby knows what he is doing, he has it all figured out

If only....

With multiple packs in parallel is using closed loop really worth it?

I am wondering the same thing. I have 6 batteries with the hub on closed loop with a inverter. One battery goes into OV Cell alarm and BMS disconnects. The Inverter doesn't care and keeps charging the others.

I unplug 3 of the 6 and inverter doesn't care. I have more issues when the is a communication issue especially when I am fiddling and the inverters turn off.

I have different protocols in my stack and now really wondering if it would be better to go manual absorption/float voltage programming.

I took everything off closed loop and am now using User Defined Mode. Long story but I am confident in my decision. Now if I only had EG4 batteries of one model I may think otherwise.

I have thought about going back to voltage only also. I just wish the EG4 monitor program had the ability to display % remaining from a built in "coulomb counter" or amp hour counter. It would just be software since they already have the hardware built in. I like the % charge line on the graph. Another nice day here but it won't get to 100% because the battery is so big and the day is short:

I could live with 2 SA setups if they could fix the jbd comms to read all 15 of them with one connection. I think it would be even better if they could read multiple bms brands/masters in sequence and report all of them in the battery report. I have 2 jbd masters and 1JK master right now.

You chewed up some electrons today. For me today turned out to be the sunniest day in a long time. Just in time for the next cold front that is half way down FL now.

I have everything maxed out at 100% all balanced and happy. The LP4V1 and E-W all playing nice at 56.6V absorption. I changed the E-W for that to be my 100% BMS set point.

I am almost at the end of my fiddling. I'll jump over to the new BMS next weekend.

I did move over to user mode on AIO and monitoring it with 2 Solar Assistants. Happy with my results.

1JK master right now.

Change out that JK for a JBD!

 

[jorby]

I could do that but would still have the SA problem.

 

[BarracudaBob]

I could do that but would still have the SA problem.

If SA can read 15 JBD batteries each what would the problem be? You would have to have a bunch of 4:1 to USB but I think SA will read them. I have used an external USB hub and had many USB plugged in. I am using 3 right now. Wave share, Vatrer, and EW V2. I had a 4th from the EG4 HUB set in Pylontech protocol it wouldn't read under JBD it had to be in Modus. Ruined that idea.

I am spoiled by the JK which SA can read 16 bms's with just one usb to 485 cable. I assume SA could read any number of JBD's using the JBD protocol over a usb hub connected to multiple quad 485 adapters, each with 4 cables to individual batteries. I have 21 bms's running right now and don't want to have to plug into all 21 of them plus the future ones. I already have 2 JBD masters and the second one can have 13 more added in parallel in the future. I am glad I have SA for the 4 JKs and the EW software for the 17 current, up to 30 total, JBDs. With a 4 port usb hub and long cable, I can look at all of them on the same computer. So I do have it figured out as far as my own needs are concerned, but I always hope for a cleaner, simpler, all in one solution, on one piece of software.

Your numbers are staggering!

I had time while marinating a nice rib eye.

So I connected the V2 RS232 RJ11 to an adapter and plugged it into the SA


Here is the EW V2


Thank you for the motivation

We had another beautiful day. 2 days in a row that I collected 67kwh. Not bad for the middle of winter. I am currently cutting trees that are shading the barn roof and south side-wall where my next arrays will be mounted. I have 540w x 30 on order. now if I could find an "alien technology" battery that had unlimited capacity for summer time.........

raise your barn with a massive air Blatter. You can then let the air out through a turbine.

either that or a up hill lake or water tower

I actually thought about pumped storage but I don't think it would work on a small scale.

You have more SUN there than we do over here LOL... goodonya! Yesterday no sun, today started about 1100, 2 hours earlier than normal.

Sorry to hear that. We had another beauty today as well. Nat weather svc says 3 more days then rain friday. Batteries hit full today, first time since Jan 9th.

 

[chamilun]

so to bump this thread. if the comms can be changed on the EW battery, why cant it communicate with the EG4? seems like should be possible

sorry if already answered above

Yes it'll work just fine with an EG4 inverter but the EG4 batteries only output EG for so that's the problem

Almost every inverter out there can take pylon RS485,

so changing the protocol on the EW rack battery to pylon, still doesnt allow it to parallel with the EG4 battery?

that sucks

 

[BarracudaBob]

If the EG4 won't change its protocol to something that's not locked down proprietary like the EG4 then something has to be open loop you either have the EG4 connect to the inverter closed loop or the Eco or all of them Open loop to the inverter.

And you have to change the eco-worthy top 100% bms reset voltage to 56.6 volts

Then everybody will play very nicely together I've done it both ways

Actually three if you count open loop

 

[chamilun]

guess I'm gonna wait to grab another EW battery. had it in cart at the right place. didnt have credit card security number on me, then they jacked the price back up...

the perils of solar buying lol
