Starting this thread to discuss Powerwall operation strategies for PG&E customers that are net generators. Trying to keep track of all the nuances can make your head spin. I'm on NEM2 EV2A and have made the following observations/conclusions: The most efficient use is directly consuming from...

I have solar and Powerwalls and I've been TBC for a while now. I'm on PG&E EV2A and have set the times and buy rates to match EV2A. I set the sell rate rate at $0.03 less to account for NBCs. When recharging the Powerwalls in the mornings it works the way I want. It prioritizes my solar...

There is a storm here in northern California but Storm Watch wasn't triggered so I decided to top off my Powerwalls from the grid. I enabled charging from the grid and set my reserve to 100%. The app is showing power coming from solar (which is more than is possible on a rainy day) and the...

Summertime in the Sierra Nevada foothills means frequent power outages. I've made an interesting observation during my last outage. I have an older 4kW string system and a newer 6kW Enphase IQ7 microinverter system. Last year during power outages when I had 2 Powerwalls and prior to lowering...

I use Time Based control on PG&E's EV2-A rate plan. I had Peak set to 4PM-9PM and Off-Peak all other hours. This morning I just happened to notice that my Powerealls didn't power my home yesterday during the hours of 4PM-9PM. I went into the Powerwall menu and there is no longer an...

I'm in a unique situation where I have the opportunity to have a 3rd Powerwall installed on my whole house backup for ~$4400 which would be ~$3300 after ITC. I'm already a net producer so I only get reimbursed ~$0.03/kWh at True-Up. The ROI for any additional surplus doesn't justify the cost...

This morning I noticed that I couldn't get data from my Powerwalls to see the status. I tried the Tesla app, connecting through my LAN (my Gateway connected to my LAN by Ethernet), and Powerwall Companion. I had the option to "Connect" via the LAN connection so I pressed that. It then said...

I mentioned this in another thread but I thought it would be better to start a dedicated thread for this. I have not been able to get definitive written answer from PG&E for this. I installed a 4kW rooftop solar system under NEM1 in 2009. I installed an additional 5.9 kW rooftop system under...

During off-peak I'd like the house to run off solar with the excess recharging the Powerwalls, and then excess solar to the grid once the Powerwalls are charged; and NEVER discharge the Powerwalls during this period. During peak I'd like the house to run off solar with the excess going to the...

Obviously, Cost Saving mode takes the different TOU rate periods into consideration. But does it take NBCs into consideration? How about battery cycle life? Or the round efficiency loss? I'm assuming it only takes the rate periods into consideration but was wondering if anyone knows for sure.

My Gateway is inconsistent at what level it commands solar to start generating again. I'm currently is a PSPS. Once the Powerwalls are full and solar has been commanded off, it appears my Gateway normally commands solar to start generating again when the Powerwalls are down to about 97%. I...

My understanding is that the Gateway uses a Neurio PB1 for power monitoring. Some Neurio home monitoring models have an app that can detect and learn to monitor appliance power consumption. I'm wondering if Tesla has any plans to incorporate appliance detection into the app or if the Neurio...

Not a Tesla car owner. Popping over from the energy forum. There is a debate on another forum on why hoods are accidentally opening while driving. How does the hood latch mechanism work on Teslas? My understanding is a single button push will fully release the latch on a Tesla. There is...

I have a newer 6kW Enphase/Panasonic system and an older (2009) 4kW string system. The system is installed on an uninhabited metal building. I'm planning on getting 2 Powerwalls. My understanding is the Powerwalls will work with both inverters but I'm concerned about the old string inverter. It...

I've hit a little bit of a snag in my SGIP Residential Equity Resiliency incentive application. My configuration is for a whole home backup (partially due to the cost/complexity of having a separate critical loads panel). My application has been kicked back because the answer to "Indicate...

Does the Gateway cell modem support the Verizon network? Also, how quick/seamless is the fallback if WiFi/Ethernet is the primary internet access and access is lost? Thanks

If power is lost and the Powerwalls shut down because the load exceeds demand, will they try again after a certain time period? Or will I need to manually need to reset the Gateway after I've removed the excess load?

I've committed to purchase and install 2 powerwalls from Tesla. I'm concerned that they've underestimate the installation cost since my system is more complicated than most. I've tried to communicate my concerns with Tesla but communication is a one way street with them. Can they refuse to...
