Since August 2023, I have been running a 6.8kW, 2 string solar array, 6kW 3-phase Solis inverter and Powerwall 2 with gateway.
The property is a self-build so there is currently minimal/zero energy consumption except when I run tools or charge hand tool batteries. I also have a sim card router running to provide internet access for the Tesla PW2, which rated at 12W -> 288W over a 24 hour period assuming it's running at full-throttle. The Solis inverter is rated at <1W at night or when there is no generation.
When I check my Octopus daily usage via the app with readings taken every 30 minutes. Daily I am seeing a consumption of ~1kW.
My smart meter is capable of vector summing, so I thought any consumption imported (hence chargeable by Octopus) on the phases not connected to the PW2 would be zeroed by the PW2 exporting energy on the phase it is connected to.
I think it's either my 3-phase inverter or PW2 is the culprit here. I expect some usage but I thought the vector summing performed by the gateway would balance/zero this energy import/usage.
Anyone
