    Happy Solar roof solar-versary to me

    Officially 1 year in service today. This took forever to sort out and get installed. Tesla corporate is probably the worst company I've ever had to deal with. The local crew was great and if not for them, I probably would have given up and abandoned the project. Anyway, we needed a new roof...

    Multiple Gateways - 3 Powerwalls - switch powerwall assignments

    I have two 200 amp services into my home. So when they installed my 3 powerwalls, they split them up and put 2 powerwalls on Gateway A and 1 powerwall on Gateway B. I have since noticed that my power consumption is greater on Gateway B. Question 1: I would like to swap my powerwall configs so...

    Data Export

    I can export Powerwall data from my App, but it's not granular enough. I want to download hourly data for the past year - ie. I want to know exactly how much energy from the I have purchased between 9am-10am, how much solar has been generated at that time across the year, the times when the...

    Which device is the leader?

    Just got solar and powerwalls (PW+ x2, PW2 x2, gateway x2). I'm confused as to which of the 6 boxes are the "leader" when it comes to reporting metrics. I'm assuming it's one of the 2 gateways. Does the app aggregate everything already? It shows PW battery at 75 on one screen and in details it...

    Model Y Home charging using Wall connector + Tesla Solar Panel + Power wall combo

    I have recently got Tesla MY and had wall connector installed from old Main panel. Tesla moved all the controls to new panel and kept the old one as backup relay when they installed solar + powerwall. I already have Tesla solar panel + 1 power wall. But unfortunately Tesla guys did not add any...

    Wondering if anyone has used a Tesla PV/ESS setup with on-demand / tankless (specifically electric) water heaters? TL;DR...could you split a 36kW tankless electric water heater across both your backed up load center and non-backed up (main panel) to have some hot water in the event of a power...

    Can I join Tesla Virtual Power Plant if I don't have solar?

    I'm a PG&E customer with two Tesla Powerwalls and Tesla Backup Gateway 2. I charge the batteries after midnight, and then they discharge during peak and semi-peak hours (3pm-12am). I don't export any energy back to the grid because I don't have solar. Can I still join Tesla Virtual PowerPlant...

    Can you help with Tesla Powerwall+ Invertor MPPT Questions?

    Hey everyone, I am getting 20.4kW Solar, 2 Powerwall+, and 1 Powerwall2. I have questions before I approve the final design. What does the Powerwall+ Input Connectors per MPPT: 1-2-1-2 mean? Tesla's design shows 8 strings to the 2 PW+ but is only using 5 of the 8 MPPTs? Any valid reason? Tesla...

    Tesla replaced my MCI units because of poor production in the winter, but now it's much worse.

    I have a 15.1kW Solar Roof that was powered on March 1, 2021 in a West suburb of Chicago. My peak production in my first summer was about 13+kWh and I was able to store some credit for winter. Once winter hit, my production was virtually nothing and I ate through my credits before December. In...

    Should I get Powerwalls if I am on an essential "circuit/block"?

    I am in the Bay Area (PG&E) and have an order for a 9.6 kW solar + 2 PW in-progress. However, I recently discovered that I am in PG&E's special outage block #50. This means that I am "generally exempt from rotating outages" because "essential services such as hospitals and police and fire...

    PowerWall or not ?

    I just moved in into a new build and I am considering installing solar + battery. I managed to get a quote for solar + Powerwall and solar + Givenergy battery. I also just realised the tariff for the Tesla Energy plan jumped from 12p to 24p with a higher daily fixed charge as well. Now because...

    2 Powerwalls: Switching from stacked to side-by-side install. What to do about the hole they already drilled on the face of the rear Powerwall?

    The installers installed two Powerwalls in my garage in stacked configuration, which required drilling a hole on the front metal cover of the 2nd Powerwall that is currently sitting behind the 1st Powerwall. The hole is several inches wide in diameter. Due to permitting issues, they are now...

    Powerwall operation problems

    Had an interesting Powerwall / Gateway problem today. Yesterday was very cloudy, and although I am on time based control, the PW did not charge up fully the previous night, so I was on full priced power from 4pm.🙁 So, last night, just after the cheap rate came on, I set the reserve % at 50%...

    Gateway 2--How do they work?

    I have one Powerwall 2 + Gateway 2 installed by LA Solar. They told me that this system would back up ALL my 30-amp and lower circuits (about 100 amps from a load calculation), transferring them to the subservice panel. But at the install, I was told I would have to choose critical circuits for...

    PowerWall w/ Solar won’t charge past reserve

    Had 3x PW installed 30 days ago. They will not charge beyond the reserve backup set point in either of the 2 available modes, self powered and Time of Use. If I raise to 100 it charges to 100 if I lower to 30, it discharges to 30

    Is your Tesla inverter or Powerwall+ singing?

    'whole home backup' confusion
