Powerwall 3 Metering Examples
Site Metering: Powerwall 3 with Backup Switch
| Whole or Partial Home Backup | Location of Non-Backup Loads | Site Metering |
|---|---|---|
| Whole Home | N/A | Backup Switch (Meter Z) |
| Partial Home Backup | Upstream of Backup Switch (Backup Switch is installed in a second meter socket) | Option 1: Tesla Remote
Meter CTs
connected to Tesla Remote
Meter, configured
as Site Note When Tesla Remote
Meter is
capturing all Site, Meter Z is configured as None. Note Powerwall 3 is not
compatible with Neurio Remote Energy Meters. |
| Option
2: Backup Switch Meter Z (Configured as Site) AND
Remote Energy Meter CTs connected to Tesla Remote Energy Meter,
configured as Site Note With this
configuration, ensure there is an overlap in the Site
monitoring. No load should be
double-monitored. |
Site Metering: Powerwall 3 with Gateway 3
| Whole or Partial Home Backup | Location of Non-Backup Loads | Site Metering |
|---|---|---|
| Whole Home | N/A | Gateway 3 (Meter Z) |
| Partial Home Backup | Upstream of Gateway 3 | Option 1: Tesla Remote
Meter CTs
connected to Tesla Remote
Meter, configured
as Site Note When Tesla Remote
Meter is
capturing all Site, Meter Z is configured as None. Note Powerwall 3 is not
compatible with Neurio Remote Energy Meters. |
| Option
2: Gateway 3 Meter Z (Configured as Site) AND
Remote Energy Meter CTs connected to Tesla Remote Energy Meter,
configured as Site Note With this
configuration, ensure there is an overlap in the Site
monitoring. No load should be
double-monitored. |
Site Metering: Powerwall 3 with Backup Gateway 2
| Whole or Partial Home Backup | Location of Non-Backup Loads | Site Metering |
|---|---|---|
| Whole Home | N/A | Backup Gateway 2 Meter X |
| Partial Home Backup | Connected to Backup Gateway 2 Non-Backup Lugs | Backup Gateway 2 Meter X |
| Partial Home Backup | Upstream of Backup Gateway 2 | Option 1: Backup Gateway 2 Meter X (configured as Site) AND Tesla CTs connected to Backup Gateway 2 Meter Y, configured as Site (backup loads must be within 100 m of Backup Gateway 2 and <100A) |
| Option
2: Tesla CTs connected to Backup Gateway 2 Meter Y,
configured as Site (backup loads must be within 100 m of Backup
Gateway 2 and <100A) Note With Meter Y
capturing all Site, Meter X is configured as None. |
||
| Option 3: Backup Gateway 2 Meter X (configured as Site) AND Remote Energy Meter CTs connected to Tesla Remote Meter, configured as Site | ||
| Option
4: Remote Energy Meter CTs connected to Tesla Remote
Meter, configured
as Site Note With Tesla Remote
Meter
capturing all Site, Meter X is configured as None. Note Powerwall 3 is not
compatible with Neurio Remote Energy Meters. |
Solar Metering
| Configuration | Powerwall 3 Solar Metering (includes SREC where required) | Solar Inverter Solar Metering | Solar Inverter Solar Metering where SREC Required |
|---|---|---|---|
| Powerwall 3 | Powerwall 3 internal metering | N/A | N/A |
| Powerwall 3 with Tesla Solar Inverter | Powerwall 3 internal metering | Option 1 (Backup Gateway 2 installs only): Tesla CT connected to Backup Gateway 2 Meter Y, configured as Solar (1CTx2) (must be within 100 m of Backup Gateway 2 and <100A) | Factory-installed Neurio meter (paired with Solar Inverter) and CT, configure Neurio CT as Solar RGM |
| Option 2: Remote Energy Meter CTs connected to Tesla Remote Meter (paired with Powerwall 3), configured as Solar (1CTx2) | |||
| Powerwall 3 with third party solar inverter | Powerwall 3 internal metering | Option 1 (Backup Gateway 2 installs only): Tesla CT connected to Backup Gateway 2 Meter Y, configured as Solar (1CTx2) (must be within 100 m of Backup Gateway 2 and <100A) | Use third party inverter integrated RGM if available (no additional Tesla metering is installed for SREC solar metering) |
| Option 2: Remote Energy Meter CTs connected to Tesla Remote Meter (paired with Powerwall 3), configured as Solar (1CTx2) |
Note
Powerwall 3 is not compatible with Neurio Remote Energy Meters.
