Suggestion reducing solar system clipping while maximizing net-metered account setup

@eg4eric Thoughts?

I should add to the above background info that my house is fully electric using heat pump for winter heating & existing battery capacity can easily be used up in colder winter temps during the 4-9pm highest electricity rate period especially given the other electrical loads normally occurring during this time in the house.

Suggestion #2 (that could be stacked on top of the simpler idea above)

feature:

• have a PV charge priority mode that will trigger based on SOC + time and have the SOC trigger vary based on calculated excess solar for the day (ie that portion of solar that would have otherwise been clipped if maxing out 18kPV's 12 kW output or reaching max grid export & batteries were already fully charged)
• variable SOC trigger could initially be taken from the weather optimize feature however a better solution would be for the monitor app to learn over time the best SOC trigger setting that would allow for optimum capture of excess solar during a day
  • learned SOC trigger: a smarter weather optimize which would:
    • factor in the system's predicted solar production for the next day; &
    • allow the user to select the building's electrical consumption factors of influence (ie in my case it is largely dependent on HDD & CDD depending on the season:  HDD = heating degree days; CDD = cooling degree days; both of which are tied to the outdoor temperature)

working mode setup:

• 2300-0700: AC charge mode to 100% SOC
• 0700-1600: PV charge mode kicks in at variable SOC trigger otherwise system reverts to self consumption until the SOC trigger (goal is to have 100% SOC by 1600)
• 1600-2300: self-consumption mode to avoid highest electricity rates

benefits:

• would allow system owners to use AC charge mode to fully charge batteries using lowest overnight electricity rates then when higher rates kick in during the day (0700) system would initially run in self-consumption mode since:
  • battery SOC > PV charge priority trigger
• at 0700, batteries would initially discharge covering loads until the SOC trigger at which point system would revert to PV charge priority
• PV charge priority would then operate as per original suggestion above increasing/decreasing the PV charge power as solar output varies 
• overall this would add a period in the morning that leverages the batteries stored electrical energy that had been charged using lower overnight rates but not allow the system to discharge lower than what can be put back into the batteries based on the calculated excess solar later in the day when PV system output is at its highest

Perhaps my original suggestion (as well as suggestion #2) above would be better suited to be in their own working mode.  How about naming it "Grid Export Priority Mode".  This would make it clear to users that the intent of this mode is to maximize grid export for those using their system in a net-metered setup.
