Has anyone done it or is there a better, cheaper alternative?

I chose powerwall 2 since tesla is popular however pricing adn spec were hard to find with tesla and other vendor's storage product.
in a fictional scenario with 1 miner + 5 1080 gtx each running at 120W (180W max) the total power consumed is 600W + ~100W (for board and cpu).
total of 700W. In one day, it can consume 16800W or 16.8KWh of energy.
The max unit storage of Powerwall 2 is 14Kwh. It appears one full powerwall can barely power 1 miner with 5 1080gtx. Obviously it does not take into account that solar panel during day will or could or partially supply power directly to miner, reducing 24 hrs.
I think your confusing K/w hours. The total powerwall can handle is 14Kw (total) single GTX1080 rig your talking about only uses 600w, that means you can multiple of those rigs. 600w isnt in one hour, that's overall.
14,000w/600w = 23~ theoretical rigs.
NO, 14kh = 14000wh is 600w * 24h. Remember what is 1WATT is following def:
The watt-hour (Wh) is a unit of energy equivalent to a single watt (1 Watt) of electricity expended for duration of one hour (1 hour).
You are also confusing watt/kilowatt (w/kw) with watthour (Wh/kWh) Look carefully.
So with that your equation can be re-interpreted as
14000khw/600w = 23h (meaning power wall can operate 1 rig for 23 hours or can operate 23 rigs for 1 hour) but i doubt later is possible because overcurrent limit implied by following in the spec:
Power: 5 kW continuous, 7 kW peak
Assuming 600w per rig, it should not safely run more than ~10 rigs at a time: 5kW / 600w = 5000/600 = ~9 OR ~10
