I have had my PW II for four months now. It took a few weeks to iron out some teething issues. The import/export sensor WiFi connection wasn't reliable and had to be replaced with a hardwired one. Some of the early firmware versions were plagued with minor issues. The app could provide better history data and been more reliable.
But.... in the last 2-3 months it has been perfect.
Nearly 100% self consumption - i.e. less than 50 kWh exported and most of that was a result of the battery being fully charged.
Turnaround losses within 2% of the advertised figure.
All measured via third party certified meters.
It does what it says on the can!
I'm sorry to hear of peoples Solar City experience in this forum but I do think the PW appears to be a sound product so as soon as Tesla get their logistics sorted I will be ordering another one to go with the additional PV I'm buying myself for Christmas.
PS Just seen the new Roadster announcement and checked with the wife and she says "Yes" (OK she said "If you must" but that's as good as a yes) ...as long as it will be available in RHD a deposit will be winging its way.
Life is good, the sun is shining (and the battery is charging)
