So, if you apply for and obtain an SGIP rebate on PW's 1 and 2 in a first install (e.g., under the small-scale residential allocation), it sounds like you can file for and obtain a second SGIP rebate on PW 3 in a second install (e.g., again under small-scale residential), as long as your entire...

Tesla sent out "the guy" today and he managed to solve the problem. Apparently it was not a CT issue, but a wiring issue. GW1 was apparently communicating with PW bank 2 and GW2 was communicating with PW bank 1. Very odd.

We'd just like to have one electric car backed-up in case of an emergency, namely a fire evacuation. I doubt we'd have much if anything else running at that time (other than maybe internet and a TV so we can track the fires). Backing up additional cars and/or other toys such as a pool pump...

If we divide by 240 volts, then we are 1/2 of 107.33 amp, i.e., our max amp draw over the course of the last year would be 53.65 amps. That's nowhere near 200 amps. I feel like I must be missing something because this should be a no-brainer to put everything behind a single gateway, despite...

Ok - I think I figured out how to do the green button calculation to arrive at avg. load in amps: (Total monthly kWh) / hours in month * 1,000 (convert to watts) / 240 (local mains voltage). So, for January, we would have: 1,138 kWh (total Jan. 2020 usage) / 744 (hours in Jan.) * 1,000 / 120...

@Vines - I pulled the green button data for the 12 months prior to our solar install (May 2020 to May 2019) (I can't download anything recent) and our maximum kWh usage for any one block is 3.22 kWh. The blocks are in 15 minute increments, so I'm assuming that's 12.88 kWh instantaneous. How do...

As an update, I made a mistake on the first calculation that our well pump was 2 hp, when it is really 1/2 hp. Making that change dropped our "amps" calculation to 198.43 per Generator Sizing Tool | Generator Sizing Calculator for Home Use and Whole House: The whole document is attached...

Totals got cut off - a printout of the gensizer.assurancepower.com website printout is below:

@Vines - in reading through other posts, some have suggested that, while their houses have 400 amp service, the house may actually only need less than 200 amps of service, whereby it would essentially be possible to split the 400 amp service in half and place all the loads behind a single 200...

@power.saver - yes - grid failure with orange x over the grid and an orange rectangular box around the outside. @Vines - yes, and thank you for the suggestion; one reason I decided to try cutting power to one system to see if they were truly independent (overheard Tier 2 support telling the...

Later this morning I turned off the first AC disconnect to try and isolate the two systems in their entirety. Doing this turned off the electricity to the sub-panels behind GW1 (house electricity turned off in certain areas), it turned off GW1, and I could hear the PW1 bank click (I'm assuming...

Here at the readings this morning in "back-up" only mode: SolarEdge app says the combined solar production for our two inverters is about 8.01 kW, so I think the aggregate solar production shown in the Tesla app (3.8 kW + 3.5 kW = 7.3 kW) (and ready by the CT's?) should be close to being...

When I put both GWs into "Backup-Only" mode during the day, all solar from each inverter will charge the respective PWs behind each GW, and the sub-panels behind each GW are powered by the grid. The solar values through the Tesla app have been close to being accurate (each shows about 1/2 of...

@power.saver. You mention that the "negative home in the first one is due to the grid showing negative with no other source". Both of these GWs tie into a common 400 amp sub-panel. Could it be that the GW on the left is seeing the negative going to the grid from the GW on the right (due to...

It does go away (both GWs in "Back-Up only" and both PWs show "Standby"): Left GW: Right GW: The unknown is the actual problem, and how to fix it?
