So technically the time between install and PTO could be ideal since it’s pre-loan payment but self consumption mode with a large enough solar and battery system can run independently fairly long.

When the powerwalls were full, and the panels would drop output to almost 0, was it less than the house was consuming? Meaning did they drop below the power needs of the home forcing grid usage or did they drop low because they could only supply to the demand?

Ah interesting. Good point. I’m thinking in my case the powerwalls will drain significantly overnight and their refilling plus home usage in summer will use a lot of the available solar generated power. That’s the hope at least!

Yeah definitely get this. Also why the panels are 23.49 but inverter is 20.9 because that 20.9 will cover likely 95% plus of production times over the course of the year, assuming there is maybe 5% during the peak of summer where maybe I get full production. Still unlikely in my case since 24 of...

I plan to the house on PWs overnight during self-consumption time period which should leave a good runway for them to charge by solar during day. I have 2 Model Ys so charging the cars with excess solar that would be otherwise wasted during the day is a good idea. However, I think between the...

Oh right - so this means, for example, if I have 4 Powerwall 2s at 25% charged and 23.49kw DC / 20.9kw AC panel system, in ideal conditions, the panels should be able to generate up to their full potential, right? The Reddit poster has 2 PWs and their 6.48kw system in full sunlight is only...

I get this if it was their policy. But why turn it on and limit it's power capabilities? Interesting. My system will be whole-home backup as well, but my advisor told me I will be able to operate in self-consumption mode between install and PTO. It was not my normal project advisor whom I...

Just got off of a call with my project advisor and he said the system would be in "self-consumption" mode prior to PTO after installation, and output would be limited. I asked him whether this means limited in that it will not export to grid (known) or actually power limited. He said limited...

Just had a call with a Project Advisor (not my normal one, he was "out today") and was told that down payment is due after inspector signs off on install, but full payment not due until ~60-75 days after PTO is given. So that was good news! Just stinks that it has now been 3 weeks and they...

This is what my paperwork says, I just looked. Thanks. However my advisor told me payment in full would be due 1 week after installation is completed last time I spoke with him. Have another meeting with him tomorrow so will touch on this again. Thanks.

Ok I better be able to since they told me payment will be due after install (technically after approval by town a week later). So I don’t want to be paying both my electric full price and the loan for months.

Do you have a "blanket" around the water heater. In your case this would likely help with efficiency quite a bit! Something like this:

I currently have gas hot water heater and gas oven/range. So I think my lowest hanging fruit will be things like optimizing car charging to excess solar, doing laundry during excess solar times, and removing extra refrigerators/freezers.

Were you able to operate after installation, or after county inspection in off-grid mode? Or were you not able to turn anything on until permission to operate from PEPCO?

Looks like my system will be similar to yours. I'm very curious to see how 23.49 DC into 20.9 AC feeding my home and 4x Powerwalls will look with different configurations of when/where/how power is distributed. My plan to remove some of our unused refrigerators and other unnecessary electrical...
