Hi Folks,
New poster here. I was hoping someone might be able to help me with my Powerwall conundrum. It arises because of the 5kW grid export limit imposed by the utility in my area.
The current behavior of the Powerwall is to begin charging in the morning as soon as solar generation > home usage. Once the Powerwall is fully charged (usually before 11am on a sunny summer day) it will switch to grid exports.
By the late morning, the Powerwall is fully charged, and I’m generating over 5kW, which is when my inverter starts throttling back the solar output. I end up with a generation curve with the top ‘chopped off’:
I estimate I’m missing out on nearly 10kWh per day over the middle of summer because of this.
Here's how I would like the Powerwall to behave:
Before 11am, just export to the grid. Don't charge at all.
From 11am - 3pm, charge the battery (but at a capped rate, say 2-3kW)
After 3pm, if the battery isn't already full, charge at an uncapped rate.
My generation graph from before would hopefully look more like this:
Any ideas on how I might achieve this?
I've played around with the advanced time-based mode; effectively trying to 'trick' the system into only charging during off-peak times. Haven't had any success so far though.
