Attached is a screen shot of my computer screen

Ooooh yeah... that's got my attention!

Wow! That is good!
Eddy if you go back into that last post of yours (EDIT) by clicking on the pencil up the top rt side of that post and then pretend you are going to add another photo. You can see the photo in the list already in there.
Scroll back to the words you wrote in the post & put your cursor after the words & then down below click "place inline".
Just gets rid on that temp line around the photo. This allows you to place the photo anywhere in the post.
Comes in handy if you want to write a description below each photo.

Looks good, no idea why it shows cell 1 and cell 2 and missed the middle 4 and then cell 7 and cell 8 .... or did you intentionally wire it like that ?
The external temp looks to read -45*C while the internal temp is 28.5*C, is the external temp sensor not connected?

My 2 units were here waiting for me when I returned from the Crystal Brook job, now I need time to do my house install so I can test one. I might install the other one on the Crystal Brook job when we do the upgrade, seems his grid feed in inverter has died and they want big $$ to replace it, so he's looking at more battery capacity and rewiring the grid connect panels to also charge the battery, then take the house off grid. The grid system is 3kW so close enough to the 120 amps max capacity of one of these bigger Electrodacus units so I can use it to control them, the other system we installed there is 5.7kW so it would have required both of them.

The unit tells you which wires to hook up when you only have 4 cells.

Hi Terry
I didn't connect the external temp sensor - do you think I need to ?

I would, that way you get a cause and effect record but at least that explains the odd reading. Should have thought to read the instruction regarding installing to a 12v system, then I wouldn't have asked the other dumb question but everyone knows the technical flow path is "when all else fails read the instructions" so I would have got there eventually

Finally got around to getting some lithium cells, got 200ah Winston cells from a Trev at the back shed.
Fitted everything up (still to refine the wiring) the solar cells have charged the battery up to 13.62v with the cells within 26mv of each other.
About 130ah went in.
Is this an acceptable difference?

[BruceS]

Yep. That little difference is good.... if it stays that way!!
Your total charge is a bit low but you can boot it higher every so often to rectify...

[froggy]

What would you suggest to set the cell and pack settings at. This is just at Dacian’s Standard settings.
