My daughter’s system was finally updated yesterday. Installer added 14 x 445w panels and 2 UP5000 Pylontechs, and she had the inverter and batteries moved to her garage, to save space in their small spare office.
As her house is already outfitted with a 5kW ITS heatpump, my old Goodwe 4.6 should serve her and the grand kids well.
Very proud of the fact that she saved up for more than a year in order to do this upgrade, and would not accept my financial help to get it done earlier.
That looks like a very neat installation.
I would not put that much faith in the holding capacity of my walls, but I saw them being built and corners being cut, so quite possibly all other walls are better…
Thanks, a very good point regarding load carrying capabilities of walls.
I may look into building a small “cupboard” under those batteries, to help support their weight.
Just an idea if I may.
Current WIP:
Had this shutterply 22mm thick x 2440 high floor-to-ceiling board installed for mounting my setup.
The weight is on the floor - board has feet to keep it “safe” from people washing the floor.
2 screws on the bottom, 4 on top the keep it upright.
Will look like this when done:
Not sure the exact size of those brackets but they look about 350 x 350 x 30 or thereabouts. Even the cheap crappy ones are rated at min. 100kg/pair load capacity, the better ones are rated at 300kg/pair. Shear strength of 3 wall bolts in each one will easily carry the weight of 2 x 45kg batteries unless she is living in a mud hut 
True, and I have not yet had a change to go and view her new installation and to “stand back, mutter under my breath, shake the brackets a bit and declare, It will do” like a true Dad
