Constant background music is annoying.. Your messaging is good, but the music causes an annoying distraction.

You are very biased in your Tesla comments. You seem to only point out the negative points with the Powerwall 3 and completely ignoring their many advantages.

Powerwall 3 allows for AC coupling so you don’t have to use Tesla panels or their inverter. I have enphase microinverters connected to my PW3

I Totally disagree. Only 20 percent of pv systems need MLPE’s for shade mitigation. Also all new modules have multiple bypass diodes that prevent entire strings getting effected by one shaded module. Like in any situations use the right product for the job. 80% of jobs are perfect for string inverters and less failure points.

Don't worry. Rather than Tesla buying Span, they are developing their own system. It will be released in 4 or 5 years, just when the rest of the market has moved on to something much cheaper and more efficient.

Solaredge is not a good "cost competitive option" option due to the high faiulre rate of createing both a weak link in optimization and a central inverter.This is proven in there plummeting stock price and installer abandonment.Microinverters are not necessary in locations with 3 or less sub arrays to a central inverter due to multiple MPPT inputs on a central inverter.We should also be talking about Enphase's requirements for monitoring (The gateway..) that is only warranted for 5 years and costs $700-$1000 to replace to honor their 25 year microinverter warranty. Modern 100+ cell panels have built in shade mitigation that makes microinverters unjustified with there initial cost in most cases. The biggest hurdel for residential solar has always been the upfront cost and return on investment. Despite Teslas short comings (wich there are more than a couple) I believe that it is smart business to make solar more affordable for consumers with equipment that is much more cost effective than the Enphase and Serviceedge technologys. SMA was the most dependable central inverter ever made and i can prove it with there inverters i put in 18 years ago. They handed Tesla there market share with there new hybrid only option that is not cost competitive. BTW, i did a Powerwall 3 install today that is AC coupled to a SMA -41 inverter, so your information is not accurate.

I jsut had a PW3 installed. I switched to their inverter by choice but didn't have to change my panels, just my MCIs for the panels. Was not a big deal. Still a one day install and now my system is actually more efficient than it was with solar edge. Furthermore the software tesla uses is so much better than the solar edge software, it's scary. Solar edge was not very good to be honest.

You can use any panels you want. Your videos are usually very accurate but this is misleading

As a Tesla owner and investor I 100% agree and can’t understand why Tesla hasn’t gone to mirco inverters on their panels vs string to the Powerwall 3!

intelligent load control So you're saying people aren't smart enough to just Turn off what they don't need.

I feel like Powerwall 3 is directly targeted at NEM 3.0.

When microinverters and power optimizers (often referred to as

Powerwall 3 is definitely a step forward:

- Closed system - Well sure you cant use other battery systems or inverters because the new PW3 is just that an all in one unit. That being said Tesla still offers the Powerwall 2 as far as I am aware for anyone that needs that flexibility.

As an experienced installer, my bias is toward system components that are all from the same company. Frankenstein systems made up of components from different manufacturers have given me a lot of problems. Personally, I also favour string inverters because I do ground-mount solar and much prefer to run higher voltage DC. You did make some great points re generator support .. I’ll have to look to see what Tesla had in mind for that. Shutting down loads isn’t a big deal IMO .. humans can use their brains and not roast a turkey when the power is out.

I chose a microinverter system over Tesla's plain-vanilla because of my serious differential shading issues. Tesla punished me when it came to the Powerwalls because I hadn't gone with their solar program. And yeah, Tesla became harder and harder to reach, downright scary.

I enjoy your videos and have learned so much about solar and have recently begun the project to bring solar to our home! Thanks Joe!

You can add the Tesla gateway to be able to use the micro inverters. Take a look at Tesla meter switch. Game changer for installers.

I had Tesla solar installed this year. The whole process went very smoothly, and I am quite satisfied with the system and service provided so far. 4kw solar panels, no battery. The panels are the 405watt Qcells, I believe they're assembled in Dalton, GA.

The Lumin Smart Panel has state of charge integration with Powerwall 3 and provides intelligent load control based on customer preference and grid status :).
