Sounds like Tesla is keeping even more money in-house. Time to get some more stock!

What if you already have SE optimizers? Will it it communicate with those over powerline or do you lose the Optimizer data?
My questions for feedback:
1. My tesla advisor says they are going to be using new "tesla branded" string inverters, says they are not going to be using solar edge or delta anymore. Does anyone know if this is true? Efficiency?
2. I'm told with these new inverters they will not use or offer power optimizers. Do people think this is a big deal if I don't have a lot of shade?
3. Despite telling my advisor, they missed a vent on my roof that would need to be moved, is this a big deal?.....
Can you mention how you benefit from SREC? I think they are non-tradable in California, or rather the fees are too high for small traders.
My roof install is scheduled for next month but I saw that there is Solar Renewable Energy Credit for 4 major CA utilities now, PG&E, SCE, SDGE and GPSD. I asked my project advisor about that and I got a new Purchase Agreement to e-Sign, with it there is a $389.00 line item credit from the system cost so my purchase price is reduced by that amount. Not a meaningful amount but I also did not expect it.
it sounds like this inverter will also fill the role of the Powerblaster:
good thing is panels will still get solar edge...
Tesla's renowned expertise in power electronics has been combined with robust safety features and a simple installation process to produce an outstanding solar inverter that is compatible with both Solar Roof and traditional solar panels.
Do all solar systems come with inverters? Tesla sent me spec sheets of both the panels and Powerwalls, but no mention of inverters.
Also, with Powerwalls, does that mean I can shut off my main breaker to the utility line and run simply off my solar system? I'd like to be able to totally disconnect from the grid and see if I can run 100% on solar
Yes to both. I imagine Tesla hasn't drawn up a spec sheet of their own inverter yet, but definitely reach out to your assigned project advisor to ask about which inverter you'll be receiving.
With the Powerwalls, depending on how much of your home circuits you have backed up on them, you can run off grid for a time. You'll need lots of sun, and a relatively efficient home if you're hoping to run off-grid for any extended period of time, however.
Seriously, with two Powerwalls, we are expecting to easily be able to live off-grid most of the time here in sunny Arizona. We just installed a heat pump, hoping that'll be an efficient climate control system.
It's a 24K BTU MrCool heat pump, hopefully it'll work ok off-grid. If not, oh well.A critical factor is if the heat pump was designed to play nice with and off grid system. A large standard start compressor can overload the Powerwalls on startup. Inverter type drives can have lower inrush currents.
I have to think they are at least considering this. One of the nice benefits of this new inverter seems to be eliminating the need for the solar gateway, just as the new energy gateway version 2 potentially eliminated the need for another breaker box. Anything that can help consolidate the number of boxes needed and also add more Tesla branding makes sense. And, as has been a recent topic here, they potentially could include smart features to monitor individual loads.EDIT: at least it will look nice, if its next to a gateway 2 and some powerwalls. Wonder when tesla will come up with a tesla branded load center, so one can have a nice, neat row of tesla branded boxes on the wall together

Yes, you're right, I just confirmed our unit online at Mr. Cool's website. Thanks for pointing this outThat has inverter technology that gives you the 'soft-start' and more efficient running. All of the mini-split heat pumps do AFAIK.
The other observation is that it is interesting it is only coming in two sizes - 3.8 and 7.6 kW. I assume their plan will be to pair one small inverter with each set of 12 panels (4.08 kW - the old "small" system) or one large inverter with each set of 24 panels (8.16 kW.) But it means that more larger installs will require multiple inverters since they don't have the 10kW+ sizes of SolarEdge inverters currently being used.
