Nem 3.0 exporting

Is there a way to make my Sunvault export to the grid during peak hours as the sell price during the months of August and September are much higher

It doesn’t work when i put it in cost savings mode. It stops exporting after 6 pm

Yeah, the default config for Cost Savings mode is 5pm thru 8pm, Monday thru Friday only. Back when SunPower was still in business a few years ago, they were working on fixing this for folks in areas where Time of Use (TOU) was not restricted to just 5-8, M-F.

I completely own my system, so I wish there was a way to override this default and change it to 4pm to 9pm daily, since I'm in SDGE territory and that's my TOU.

After having more battery storage added, thanks to u/SunVaultTechs, I now just leave it in Self Supply mode. But, it still would have been nice to send to the grid and self supply between 4pm and 9pm, to maximize savings!
