Is Generac Power Wall a good solution?

If you have existing solar and over 10 years on your existing inverters would this be a sensible solution at the point of failure on the inverters.  

Personally the only driving factor for me would be to level out the real peaks in usage as I already have a pretty good grid tie plan and so far the PVP5200s keep ticking along.  Replacements are right at the $3K each.  Pricing information for the Generac seems a bit thin.

    Dave,

    Do you have a link to the product? I am a bit confused... Tesla's brand for solar backup power is "Power Wall"... I could not find anything about Generac Power Wall...

    My buds who install both tesla and generac "walls" say Tesla. Generac had horrible support and it is too new.

    I helped a guy convert a model 2 to offgrid. It was not very hard but no warranty and no app that is pretty nice with Tesla.

     sorry for the confusion it is called the Generac Power Cell. Here is a "third" party review:
    https://news.energysage.com/generac-pwrcell-battery-review/

    here is generac site:

    Looks like you can run your critical loads off grid for some period of time the largest model is 17 kWh and 2 can be strung together.

    BTW 34 kWh would be a real push here to get through about a day or 2 with minimal cooling needed. But there is the emergency level of consumption to consider.  this does look like a good cost shaving for grid tie with extreme TOU rates and can be programmed as such to replace some grid power during expensive rate times.
