I’m curious what the PW 3 surge rating is?
Anyone know?
And where would it be found, I can’t find it.

No warranty is no warranty. Would love it if Elon would go offgrid.
The model 3 is almost there. I did build an xw into a powerwall with bad
electronics. It is still running.

David, Wrenches,
I would not recommend that as it may be a warranty issue down the road and
last l heard is it must be monitored at all times and if there is not a
grid even though it's AC coupled could ba there issue.

Thanks, Vincent. This is the information I needed.
I did read that at least 1 MCI is needed even if you do not require RSD. The MCI
instructions are a bit confusing. I know for RSD you need one at the start of a
string and at least one every three modules, but it's unclear if you need the

Last time I spoke with Tesla, they did not support either fully off-grid or
installations not connect to the internet. Have they changed their policy
on this?

Correct, but there are some off-grid scenarios where a generator with a
transfer switch would be an adequate redundancy for rare solar/battery
capacity deficiencies.

I hear 3 still can't use a generator from youtube. Pretty cool other
than that.

Keep in mind that 7.5kW is max charge/discharge for 10 sec...it is NOT the

Let’s say a single Powerwall 2 is at 50% SOC and there is a utility outage

You can just land the new PV to the same "generation" panel that already hosts
the 3 Powerwalls and existing PV inverter output breakers. There should be no
loads on this panel. The Powerwall AC coupled solar limit is 7.5 KW AC per
Powerwall, note AC not DC. The DC rating is irrelevant here. If

This customer with an orphan PW, not to compromise the factory warranty on
the batteries, it would be safest to just grid tie any additional PV and
not touch the existing system from the gateway down.

Hello, I hope this helps. I have very little PW experience, the one i was
involved in had a 1741 transfer switch with grid monitoring on the mains.
When the grid failed the switch would disconnect from the Grid and connect
the PW to the panel or sub-panel. The PW charges from the AC source when

Hi Kirk, the maximum actual charge rate is 5kW per Powerwall. When you
exceed that, or start getting full batteries, the Gateway tells the
Powerwalls to frequency shift to 62-66 Hz.
This takes the UL 1741 listed inverters out of the sweet spot, and they
stop or curtail production. However, predict
They used to advocate 7.9kW AC/DC per Powerwall. That number may have gone
down recently. Coupling an inverter on the line side of the backup gateway

Hi Dave,
Yes, your understanding is correct. No access to DC terminals. Definitely
not a great off-grid solution and is complicated and clunky at best to
integrate a gen.

Hi Hilton,
We've done the math for our installed cost on the Powerwall 2. Certainly,
it wouldn't make sense to purchase it just for energy savings alone with
current California residential electricity tariffs. However, most folks are
buying it primarily for backup purposes and then a little bit of
