Hi Guys,

today I finally decided to by a Batrium WM4 starter kit for my Powerwall.
It was not an easy decission as it will cost me around 1T including TAX and everything.
As a first step I'm building 14s60P, which I will then connect the WM4 to.
I hope this was the last Expensive invetsigation now for my system now.

And I sure as hell will need support from you to set it up the right way.

I'm going on Holiday for the next week and after that I will start adding the busbars to my packs.

So, wish me luck :D

regards

Congrats ....I think you will really like the Batrium once you get it going. But as one that has learned some hard lessons ....double and triple check when connecting items such as fans, shunt trip breakers etc. to it. Know your current demands etc. before connecting anything to the outputs especially. This comment is notmeant as a negative just a cautionary one. Enjoy the Batrium!

Hi Headrc,

thats's why I said I will need support.
This equipment is much to expensive to be not carefully ans check more then once.

Thanks.

Gentlemen,

I can confirm, my new Batrium equipment has just been delivered today. Didn't expect it so fast.
What I don't understand, I didn't have to pay any taxes or extra fees or toll.
Does anyone have an explanation for this, or do I have to expect a letter from the government in the next days?

Now I have to speed up with my Bus Bars and cabeling.

Almost certainly.

Here in the UK DHL tend to either send notification that you've got an import tax bill owing before they deliver, or they'll deliver but expect instant payment before they allow you to have the item - or they'll wait just long enough for you to think you aren't going to get a bill, and then they'll send it.
 
Hi Guys,

as expected, first issues appeared on installation:

1. Toolkit is telling me, that there is a newer software avalable,although the icon is green ( I think the toolkit Software is ment here, my Version is from the homepage 2.0.12.0 ) When I try to update it for WM4 I get the error message in the right corner: No Installer update available for this", which is a message I didn't see in the documentation on the Batrium Homepage. So no update possible.

2. Toolkit is telling me also, that the Supervisor needs a firmware update, although eventhis icon is green.
When I start the update I get a succes message at the end, but Toolkit still says, update necessary.

Connection icon and Wizard Icon are green also. Actuall Firmware Version is 4.9 as Connection selector tells me.
This doesn't change after a firmware update is announced to be successfull.
I used the original USB cable and two different Pcs for testing.

Has anyone an idea how to solve this?

What I realized now, the cellmon cables are different.
I got 16 overall, 3 have a black and red cable for connecting to the battries, 13 hav only a red cable.
In any description I always see that this cable should have always black and red cables.
Or is this a new solution? Does anyone have some input on this?

regards

For #1 and #2....
When I first got my Batrium I had the same 'update' symptoms/issues. In my case I had downloaded 1.0.31 toolkit and I needed the 2.0.rc7 toolkit... e.g. Batrium was not able tohandle all the different versions of toolkit. So I suggest checking with Batrium or checking to see if you can find an different versiontoolkit that matches your WM4.

Cabeling - there are plenty of helpful web pages at www.batrium.com:
I have longmons. Each of mycables has has a 4pin connector withred/black -> battery and yellow/blue -> 2pin connector for next mon.
Like this:https://www.batrium.com/products/cable-longmon

You probably have a CellMon extension cable that facillitates connecting the watchmon to the chain of mons...
Like this:https://www.batrium.com/products/extension-cable-with-cellmon-connector

You might have a shunt cable as well?
 
Hi,


I will check for a different Toolkit Version.

Here's a quick pic of what kind of Longmon cables I got.

I also got a CMU cable for connecting the Longmons to the WM4, but I still think, the Longmon cables are wrong, because in all pictures on the Batrium side, they always have a black and a red connector for the cells.

Did you get Leafmon wires?

Hi daromer,

I don't know, did I?

Are three wire cables for leafmon?
I will check online.

Thanks for the hint.

No , they are not leafmon wires, on my 13 cables the black cable is completely missing.

I will check with Batrium tomorrow.

You have received 3x longmon cables and 13x blockmon cables... Blockmon cables don't have a black wire because the blockmon connects directly to the cell -ve terminal.

Hi HughF,

you're right , just got the feedback today from Batrium,

they are Blockmon cables and I will get replacments for the wrong ones.

I hope to be done with adding the busbars until the new cables arrive.

Gentlemen, it's alive, finally :)

With support from Daniel and a new Toolkit version from Batrium today I finally got the system running. Big Thanx for this.
But I must admit, the journey is not at it's end, means I have no clue, how to configure the system to handle my Batteries.
I watched all available videos on youtube, e.g. from daromer, hbpowerwall or average Joe, and I still don't understand where I have to tweak the system exaclty the way that my Cellpacks are keept in my prefered rang:
Can someone please help me here:

I want to keep my cells between 3,5V(lowest) and 4.0V(highest) and have them fully loaded at the end of the day.
My Inverter is set to
Bulk 54,9V
Float 54,4V

image_kcooss.jpg


I think it should be set to 56 V for full capacity?

But which values do I need to set in the Batrium Toolkit?

You'll kill those 3 mons if you run them at that temp.

Ok, can you tell me how to avoid this, which parameter is responsible for this?

I have added my settings, maybe someone can check and correct me where I'm wrong.
Like I said, I want to keep the voltage of my packs between 3.5 and 4.0.

Cellmon:

In Cellmon, reducethe bypass current limit - probably down to around .6A - you could manually drop those three cells with a resistance, that would be kinder to the mons, rather than having them run at or above their thermal max.

Thanks for this tip, will try to find an external resistor solution.

Can it be done, while the pack is still connected?

I changed the bypass limit now to 0.6, as you recommended.

This is how it looks like atm.

image_xsfubx.jpg


But how do I get them all to the top, maybe around 3.95V, atm there seems to be no charging...

Update: I changed the Float value on the Inverter to 55V and now it has started with charging
 
You can set autolevel or you configure the Charge voltage to a level where the bypass function kicks in on the top ones

Ok,

I set it to auto level, but still don't understand the action and where to tweak that all cells keep on the same level.
Especially cell 13 and 14 are lower then the others and I don't see any kind of charging on these cells.

Or do I need to be more patien, because this needs time?


image_svnyqk.jpg


Any further recommendations, which values I need to set correctly? Should I upload my settings maybe again?

Still trying to understand the function, watching videos over and over.

By the way, can I somehow export the settings to keep them save before changing something, or to import it later again?

You appear to have the charger Vmax set to 56v, and your pack voltage (measured by the Batrium shunt) is also 56v - so given some small allowance for error it's no surprise that you'll see little if any charge current - the charger thinks the battery is full.

How much PV is attached to the charger, and do you see an increase in charge current if you increase the bulk charge voltage (temporarily) by 1 volt ?

Also, you previously appear to have bypass voltage CV9 set to 3.98 - that's the voltage at which all cell voltages will converge - the last image illustrates that you've now altered that - perhaps to 4.03 - you'll obviously need some charge input to bring the remaining cells up into bypass.
