I currently have 26 solar panels generating 6kw. I’ve added a new Tesla vehicle, and am ordering a new 9 panel system generating 2.6kw, and a Powerwall.
The designer is suggesting that the new battery be installed on a sub panel with the house, existing PV system, and car charger. They are recommending putting the new PV system on the power line side of the gateway, in order to keep the maximum load from the PV below 7.6kw for the single Powerwall.
Under normal operations, this seems fine, but if we lose grid power, we’ll also lose power from the second system.
Is it possible/desirable to provide some way to utilize the power from the second system during a grid failure without overloading the Powerwall?
We typically feed power into the grid during the day, unless I’m charging the car, in which case I’m drawing power from it.
Does the gateway interact with the Tesla home connector to set the appropriate charging rate depending on available PV energy?
Are the tools in the Tesla app sufficient to monitor charging versus grid power if one of the PV systems is on the line side of the gateway?
