NO TECHNICAL SUPPORT.
Avoid. the powerwall in the UK. The technical support is utterly useless. Bought the powerwall 2 last July. Took nearly six months to get on the Octopus flux tariff. Then a big storm, and powerwall worked to give us power during outage. Then it went on the fritz. Hasn't worked since. Their customer care utterly useless. In nearly 2 months we've been given a reference number for our complaint and been told we've been 'escalated to tier 2' whatever that means. I can't think of any other company that has treated me with such contempt.
