It looks to me that some of the electrics are directly below a water tap. If correct, that's something I wouldn't be happy with given that taps have been known to drip.Ok so we had the power wall fitted on Wednesday as quoted - as they had a little more fiddling with data so they didn't complete install until late in the afternoon.
I am thinking of adding a third PW2 but am concerned to read the dimensions have changed as it may look a little weird stacking a third one in front of two original sized ones.
From my own experience, stacking Powerwalls 3-deep is not an allowed configuration (max is 2). That was what I was told by Tesla, but don’t know if this varies by country (but certainly true in US). If true, your 3rd one would need to go to the side. If so I have some info for you and I think that would be no problem:
Yup, checked today and the recommended max for stacking is three and as mentioned above, there is very little difference in size. On reflection, I will probably just start a second stack anyway as we will probably end up with four eventually as the DNO has signed off another 6kWp PV.
Does anyone have a link of how the powerwalls are installed in stack of 3? I'm looking at getting 3 power walls, and the company I got the most detailed quote from was installing them all individually, with separate shut-offs and critical load centers, thus driving up the price of labor+materials. Is there a difference between their output/performance when stacked versus separate? Are they done in series versus parallel?
