Now a few weeks in having our Powerwall 2 upgrade added to last year’s Enphase IQ8 based solar installation.
Very pleased so far. Some testing still to complete but the system appears to be working as advertised so far, and quite well actually.
Very high wind event last night had Xcel utility killing grid power for the better part of 24 hours just north of us. We never lost power but feeling less foolish about this upgrade.
Stormwatch has engaged as expected since we enabled the new hardware.
This kind of pre-emptive grid outage is new for us in our area. I’ve been anticipating this kind of thing since the Marshall fire in 2021.
System:
18 west facing REC Alpha Pure Black 400 panels online since 5/23
3 new east facing REC Alpha Pure Black 405 panels added 3/24
21 IQ8A Enphase micro inverters
1 Enphase Combiner Box
1 Powerwall 2 battery added 3/24
1 Backup Gateway 2 added 3/24
Combined nominal rating: 8.4kW
AC and car charging circuits excluded from back up. All others covered.
Installed by Photon Brothers.
As our baseline usage runs about 16kWh per day, and we don’t live where we need to run the AC long hours hardly ever, we went with the system spec’d above. We have mostly gas heat.
We own a 2019 Leaf SL+ as an urban corridor runabout. It works well for how we use it.
Running 50% backup reserve under self-consumption, and the battery can effortlessly carry the house from sundown to nearly sunrise overnight, unless we’re charging the car.
