54kWh doesn't go far for air conditioning in September in Southwest
Florida. Trust me. Most homes have $200+ electric bills at $0.10/kWh
this time of year, sometimes substantially more.
Generator backup, even with 4 Powerwalls, is necessary for
mission-critical grid-tied backup situations. Sadly, you can't charge
Powerwalls with a generator. You just bypass battery storage and run
loads straight off the generator, which means the generator needs to
be sized for the whole home. It would be nice to have a generator
input for supplemental charging at least with a small portable unit.
There is no perfect solution for this application. At least no
cost-effective solution.

Hi Bill -
I completely agree with your statement about all off-grid
applications. Most if not all need generators. And, I do think
there are some grid tied applications where generators make sense
too, especially for folks who live way out in the woods as you
mention. I was speaking about the mass market in CA in cities or
towns where the grid is typically fairly reliable. If you install
four Powerwalls, for example, you have up to 54 kWh of storage
available. There are applications where generators make sense,
and all these fires and smoke and heat waves prove the point. I
think AC is critical for some parts of the country, and energy
storage + PV alone just won't cut it for those critical applications.
But, yes, good point.

August,
Quite frankly and with due respect about the
comment about more PV and battery to forego the need for a
generator, I disagree. Those folks living off-grid in the
sticks (um,er, myself included), it would be a very bad thing
not to have Gen input. The current situation here in Plumas
county (and many other counties right now) is another
perfect example. It is so smokey that my daily KWhrs has
been cut in half and of course every other off-grid home is
having the same issue. This has been going on for almost a
month with only occasional breaks. There are also CC
failures, FET board craps out, other excrement occurs.
We all know there are many critical needs for
power especially to run a pump for fire protection, frig for
food, communication to know what the hell may coming your way
during some event (fire, flood, bad weather) medical needs,
etc. In the winter there are at least a few times when there
is little or no sun for 1 maybe 2 weeks...that gets to be a
spendy array and battery. Certainly, the idea of going that
route works for some scenarios but not off-grid. Generators
are still a much needed necessary evil. Maybe its a big deal
to incorporate that feature in an inverter?? Sounds like
bean counting.

In CA the market for ESS is primarily grid tied support
features driven by SGIP + backup (public safety power
shutoffs, folks who live in less stable grid areas, folks
worried about natural disasters) so the ESS is designed to
replace generators. This might be a little trickier for
areas that need air conditioning during a grid outage (or
for all electric homes), but one tactic is just to go bigger
with the ESS and PV system. I guess what I'm saying is that
the value proposition might already be getting better just
to skip the generator and go bigger with the storage. Even
Generac might be going that route.

We are seeing tons of companies in Florida offering
Generac/Pika now. They didn't do it when it was Pika, so
why would they now that it has an orange label? Crazy.
No generator input makes zero sense and even less sense
for a generator manufacturer.

Jeremy,
Pika was bought out by Generac and rebranded as
their PWR cell. Most of the old crew from Pika are
now working for Generac. It's beyond me that Generac
bought them and yet they still don't have a
generator input. That's why I could never sign on to
the Pika product line. Good luck.
