    In your case, if the grid goes down, you need to throttle the air cond way back, and cut your loads to the bone. When smoke from wildfires blows in, even light smoke cuts my harvest 50%. I was running my backup generator in the fires of 2018 because my solar was zilch from the smoke, and I was 90 miles north of Santa Rosa.
    I wish I could get back down to below 30kWh per day but with 2 shed AC units and my RV AC it seems my usage had grown a lot since my move. If I turn off any of the AC units I will have temperature issues with the stuff that is inside those sheds and RV.

    Most people with a large home will burn close to 50kWh a day.

    The price has gone up since I got mine for just shipping, handling and tax. For a $650 charging station it is still a good deal. It may be more than you need for the Prius. However the $5 per month gives it a 4 year payback and and more capacity for a future EV. Howerver it would most likely require a bigger receptacle and new circuit to be installed.
    Thx yeah probably don’t need that for the Prius, but as far as mode it still needs final inspection by PG&E so it’s not connected to the grid yet. Originally they had the battery designed to not be connected to the electric panels and only be used by outlets.
    when the electrician was hooking it up he told us that and we had that changed. they are now connected directly to panels so we may be able to load shaved. Will know more once we get connected.

I don't get charged each month by SCP. It is all on one bill prepared by PGE. I can provide more details since I have attended some of the SCP meetings before C19.

    Maybe I need to start from the beginning Vivint offered to install our solar system at no cost, we agreed to pay Vivint 21cents per kWh for 20 years limited to 3cents/per year rate hike. We either pay SCP POCO only if we don’t produce enough power. At least that’s my understanding.
    We kind of jumped in without much research because PG&E has been such a **** show up here and we saw this as a way to lock-in rates for 20 years and solve our power problems during the summer at no cost.
    If you don't own the system then your options are limited in terms of user settings. Can you tell which mode it is in? I am not sure what the purpose of batteries were if they can't be used for load shaving or backup? I may be missing something, I will reread the thread to see if it is more clear.

    Yes it depends on your usage. Most of the planned power outages we have had in Sonoma County are during clear weather and your solar should be able to provide your power during the day and then, depending on your usage you should be able to get through the evening on batteries.

    Hi my name is Sean,
    We just had a Vivint Solar system installed with two batteries that should produce 15% more power than we currently use. My question was we are currently receiving power thru Sonoma Clean Power but the Vivint guy who set up our system suggested we switch back to PG&E I’ve tried to do research but info is hard to come by. I think SCP rates are slightly lower and the double PG&E rates when settling up at the end of the year. The only down side I could see is SCP each month charges you if you use energy off the grid beyond what your panels produce but PG&E just settles up at the end of the year. Since we should be producing more power than we use that shouldn’t be an issue right? Any info or good source for research would be appreciated!

So I’m almost certain in most cases we will produce more power than we use.
    But unless the power is shut off we aren’t apparently going to running off the batteries. I was told by the designers that they can’t do that. Charge up the batteries then run off batteries instead of the grid.
    But if the grid is down and you have cloudy days what is going to recharge the batteries?

    My guess is that if you get a few days of clouds you will end up purchasing power from your POCO even if you do over produce yearly. Also during the winter your panels will be producing a lot less during the day time which may lead to purchasing power. Is that going to be ok with either POCO or will you be charged by SCP?
