UK Nissan e-NV200 / Leaf 14kw Powerwall 14s4p

Can you make a schematic diagram of the wiring. I think that'll help to figure out what you're doing wrong.

We are fully operational. The VRM portal issue was due to a corrupt configuration file which Victron support was able to fix remotely.
I have rewired my Victron so that the AC-In is now connected to the mains and not AC-OUT1 which it states in the manual. I do not have a critical load configuration in my system for now.
With regards the Batrium side of things, I am currently using ESS and not DVCC and it seems to be working as per the batrium specifications.

I will get a schematic diagram drawn up soon and posted here

That looks really good. Have you done a capacity test to see what you are getting out of the used leaf batteries?

I haven't done a capacity test as I do not have the equipment to test. Any recommendations that should work with leaf batteries (that wont break the bank)?

Fantastic! 
Im working on a Nissan Leaf system using the same Multiplus GX. Using 2 leaf modules in parallel so smaller than your system. Any chance you can share your VE Config file?

Hi BigDav,
Any update on your wiring schematic?  I'm also about to embark on a similar system using up to 48 x LEAF batteries, Victron Multi-Plus II GX and Batrium WotchMon Plus. What are your thoughts on the "best" battery voltage to configure the LEAF batteries and also the Batrium Plus rather than using the WM4 with LeafMon?

Looking forward to your next updates Smile

I have my minimum voltage set to 3.5v per cell and a max voltage of 4.1v to preserve the battery life. (49v-47.4v)
With regards the Batrium, I went for the WM4 and leafmons, simply as that's what most of the other leaf builders recommended to me when I first decided I was going to build a powerwall. The leafmons are custom made for the leaf batteries and even Batrium support recommended the WM4 over any of their other products for my build.
If I get a chance over the weekend I will try and draw a schematic diagram (I can barely draw a straight line with a ruler)

Here is my charge curve for a new Gen2 module that I did on my Icharger 4010 3.2-4.15v  It really sucks up the juice on the higher end of the voltage range.  I dont think i'll bother going below 3.7. 
 
I have 58 new gen 2 cells to put into a powerwall.  I'm thinking 18P3S for my 24V system and going 3.7-4.1 (maybe 4.15)  I'll have them in a conditioned shop, so they should not get any extreme temperatures

Bigdav.  In one of your first post, you were going to bolt the modules together with MDF.  You didn't say why you were advised against that?
