Powerwall question

[Rhian]

Hi everyone, we are considering a powerwall - UK.
The question is there a minimum energy/wattage required from the solar panels input to be able to store solar energy into the powerwall?

For example, EVs won’t charge if the output is below 1.5 kw

Thanks in advance.

The PW will use any solar generation not being used for domestic consumption (until the battery is full whereupon it goes into standby and the surplus power goes to the grid). See if you can understand my PVOutput graph but note that to see the battery data (called extended data) you have to click on the right-most square blob under the date selector. The only possible constraint I have noted is that the battery appears to work in power increments of 10W but that may be the reporting system.

Works perfectly with small PV as I have a 1kWp with my PW2.
