Solar systems widely available but... questions get no "Real" answers.

They still have them if you know where to look

And last time I checked there wasn't any considerable difference in price for all the trouble of assembling the components.

I started looking in building my own batteries. It is not a complicated concept and despite what everyone say, on paper it looks to be a lot cheaper

When I did my research into building my own batteries there wasn't much difference in cost. It didn't seem worth it to me.

To make an equivalent of a pylontech us3000 battery (48V 100Ah).

Affordable Lithium Batteries

Putting the power back into your hands

lithiumbatteriessa.co.za

15 of the above cells at R1,024.95 each = R15374

I haven't added pricing for a BMS yet, or an enclosure, or wiring, etc.

A pylontech us3000 can be had for around R17500? And that's assembled and tested and working, in a nice clean/neat enclosure, ready to go, with a warranty.

The biggest factor that puts me off from building my own lithium battery is looking at information from:

ITP’s Battery Test Centre | ITP Renewables

batterytestcentre.com.au

These guys test a whole bunch of different batteries from different manufacturers. There are a LOT of failures from big manufacturers.

Seems pretty unlikely that I can do a bit of 'research' on google/forums and put together a better battery than these big companies with huge R&D budgets and years of experience.

TL/DR: My feelings is it's not cheaper to DIY and I can't build a battery as good as I need if big experienced companies are even struggling occasionally.

Agree.

Also, the warranty offered by the likes of Pylon and Hubble, FreedomWon etc makes the slight extra cost worth it.

I considered Hubbles but went for these...

Could you give a breakdown on why you went for these. There are quite a few threads where people went with batteries but no one really explain why the bought this battery instead of that battery.

It was basically reputation, I have friends, colleagues, neighbours and a friend who installs systems with them with zero issues and great feedback. We are looking at using Hubble’s in my inlaws upcoming 3 phase install with a 12kw SunSynk inverter and may do the same at our next house when we find it.
