In the case of a flat slab roof, there is no fix. Been there tried that 3 times. Never again. Only solution, put a new roof over the slab. No more problems.
This is what I’m going to do with the garage also.
Well I am one battery richer.
Was crying all they way back home from Jhb. That saying comes to mind, buy once, cry once.
True, but I learned about Hypercrete with additional sealant mixed in. It is gray, like concrete and applied on walls/concrete/inside mines.
Then you paint over it, for more sealing + protection against the sun.
Learned that roof paint, white, lasts the longest on outside walls/roofs. The moment you add color to paint outside … yeah.
Just a thought to ponder on, IF you want to give it one last go before the roof costs. Stopped our walls leaking one time… and they face the North Easter.
Our thoughts are with you … 
Thanks Jaco. These all were eTowers and/or Lite’s also?
Hi, the lites comes with problems of their own. They come with wires from the factory and if you dont cut them, you should be fine. The internal issues, well thats something else, for another day and another thread…
Roger that thanks. Shunt hall diff and all that… 
So the void has been filled.
Very impressed with how the system is performing, save for one little thing. I know this has been discussed a number of times in various threads but I cant seem to find one of the relevant ones now.
I also seem to recall that this could be due to a number of reasons but, the BMS/GX now only allows an 98% SOC.
In my mind, I assume this could be any/some of the following:
- dip switches not correctly configure
- Different software version on the new battery which is now the master
- New MPPT that has not been given identical settings to the other 2 (tail currents, Peukert etc)
- Cells that still needs to balance
So 2% is nothing I know, but oh my OCD will eventually get the better of me.
Do I leave it for a week or 2 and see if if will correct itself?
Keep it on batteries charged? (the scrooge in my screams against this)
I would like to check out the MPPT but this latest one does not have Bluetooth, so I’m assuming it could only be done with a cable and pc and therefor am stuck.
Oh yes and I did let the 3 batteries drain to roughly 50% before the new one was connected. I never got to see the SOC of the 4th one though.
I’ve also managed to see that the 1st 2 MPPT’s is on version 1.61 and the new one still on 1.59
Ok clever me at least got something right.
Managed to updated the MPPT.
Not even going to attempt the Venus or the Multi as this will be a stuff up. TTT usually does this for me. 
My FW tends to sit at 99% for a while before the last step to 100%. Might this be the cell balancing phase?
Perfectly fine, balancing taking place if you check the 143w, 2.6a still going into the batt.
Leave it be for a few weeks.
Mine reaches 98%, and now 97% before 12h00 and then stays there the entire day. If I switch to keep batteries charged, Eskom jumps on the wagon despite there being ample PV.
EDIT. Tried it again now after the update and it seems that PV is being used now and battery is accepting amps.
2ND EDIT Spoke to soon. Sitting at 98% again and no amps in.
Hold the phone guys. It seems I’m able to access my non Bluetooth MPPT through the Victron Connect App on my PC.
Checking the settings now.
And this does not look lekker.
The other 2 MPPT’s are set as user defined.
Absorption and float voltages also completely different!!!
What should equalization voltage be?
On the new one it was set to 67V
On my other two these are disabled. How do I disable it? If I type in 0 Volt it automatically sets it at 32V.
I think for the time being (cause I can’t find the recommended settings for tail current, Peukert etc), I will just go select all MPPT’s as lithium batteries, and not user defined.
The voltage on the battery is too low. Set max charge to 55.6v and it will show 100%.
