    Hi
    Apart from the aesthetics and having a single source manufacturer solution in one box, what's the benefit over something like a Victron Multiplus solution which effectively provides the same technical benefits when correctly specified and installed, with the added advantage of likely providing a more future-proofed scalable solution at a lower initial price?

    I'm a fan of Victron. That said, 3 points appear to favour Tesla:

    1) Victron installer base is arguably more niche than Tesla
    2) Tesla aftesales/ tech support is good. 
    3) App integration is market leading

    Not sure if the Multiplus can match the disclosed specifications (charge/ discharge rate of 11.5 kWh as an example)? but if it can then it is definitely a viable alternative.

    Hi
    I believe their 48/10000 is rated for 8kW continuous at typical operating temperatures, peaking to 18kW for a supposedly decent time-span (minutes, not seconds!) and there are unit options both larger (eg 15/27kW) & smaller to suit individual requirements.
    What I do like is that their units can be fully operated & data/performance interrogated without access to on-line services, which is probably a decent thing when considering outages or suppliers not maintaining on-line services, ramping up costs of those services, or going bump ...

    Just one - took a full day to commission and this was a long time ago. Definitely not a plug and play solution but to ZE's point, highly customizable and good performance when done. Definitely worth hunting down an experienced installer.
