@Erastus Wow!!! Congrats, wonderful project - your "blow by blow" is awesome, keep it coming...
Just so happens that I have been Youtube'ing for the past few months on this very topic but for me, it is a pipe dream - day job get's in the way of me ever pulling a project like this this off.
Based in Durban interior and hope to be completely off grid in the not too distant future. Winter is our best time for Solar but Spring and Summer is challenging in terms of Solar. We can go an entire week with 100% cloud but thankfully we mostly have wind during these times so this is just what i'm looking to add to our setup.Look forward seeing the final product once you have it all wrapped up...

Hi All,
Weather intervention blew Ethernet Port on my CCGX. Have installed new one, firmware updated, all configs done.
Linked new CCGX in VRM under my account and went thru the sequence of replacing CCGX on my existing installation, rebooted CCGX etc - doesn’t seem to have worked
New install hasn’t been linked to my old installation and all updates are only showing on the new install, no historical data.
The VRM id on my old install looks “odd” in that it has additional explanatory text…?
“fxxxxxxxxxxxx - USEDASREPLACEMENT”Anyone have any insights
Thanks

What did you get
I am planning to go off-grid but not there just yet, still a work in progress. There are a few guys on the forum that have gone the DIY route, buying cells and related components to build your own. You can also buy ready built units. Bain and his team at Lithium Batteries SA (LBSA) provide a quality product/service - link at the bottom
Got my first 48v 120ah (16s) setup in August last year and acquired an additional set each month thereafter - 4 banks, 24kWh. Since I was getting 1 bank/month, initially I ran them as separate banks, each with it's own BMS. While this works, this setup is not ideal as charge/discharge rates differ from bank to bank. I have since acquired a 250a Smart BMS and combined all cells into 1 large battery - 16s4p. BMS has a phone App and one can monitor battery/cells - much better8 hours ago, Scubadude said:how does it integrate with the rest of your system
I have a Victron Quattro and at the moment, the BMS is not connected to the Inverter, so I have my setup charging at reduced voltages to avoid cell voltage runaway - equates to between 90%-95% of battery capacity.
Hope to soon try out a serial battery driver for Victron created by @LouisvdwHere's a thread on DIY build using BMS with no comms
Here's another thread on DIY battery - if I recall, Justin has a Sunsynk inverter
and finally, here's the link to LBSA - https://lithiumbatteriessa.co.za/
Good luck, have fun -

My rough sum was R19000 for a 3kWh battery, 80% DOD and 3000 cycles (half of the claimed 6000 cycles as real world never matches theoretical calculations or similated conditions in a lab) for a conservative R 2.64/kWh
Always an interesting discussion with many different perspectives. I haven't done a detailed analysis but I have a DIY LifePO4 battery (6kWh @ R19300) and using the 3000 cycles/80% figure, I am sitting at R1.34/kWh which beats Eskom by a bit. Battery cost/kWh is pretty much fixed whereas Eskom cost/kWh is a moving target and will increase over time, 15.6% in April for starters. If I treat my batteries with kid gloves, I could achieve more than 3000 cycles which will be a bonus

3kw heat pump it uses on 750w
Morning, looking into heat pumps - which one did you install and if you don't mind, what did you pay for it... thanks

Hi @Louisvdw
Excellent thanks, will do -

I'm looking for people willing to help with testing this driver for other BMS like AntBMS and Daly
Hi Louis, I should have my re-configured battery with a 250A DALY Smart BMS running in the next few days
Setup: Quattro 48/10000, Color Control GX, SmartSolar MPPT, 24KWh DIY LifePo 16s4pI'd been keen to try out your driver but I will most probably need some help
Thanks

We on Eskom direct and have had a fixed charge for years which has been steadily increasing, about R1800/mth at present before we switch anything on - will be off grid later this year
