SCE numbers

[OftheSeven]

Maybe I'm overthinking this, but hopefully, someone can confirm. My Enphase shows I produced 571 kWh during my SCE billing period. I have a 4.6 kW system.
My bill shows "Net generation" of -296 kWh. Is that what SCE sees I sent to the grid, minus usage during the same time? Or should I be concerned about their numbers?

I also have two EVs and wonder if there is any advantage to charge them during the day during generation or at night since I'm on tiered.

I would not be concerned about SCE's numbers unless you have consumption data that disputes the net generation number. I do track usage and production each month.
I charge my EVs during the day from excess solar because there is no incentive for me to end up with a big dollar credit. I do not charge past 4PM because that is when the rate is higher and i do want to get that high value for the few kWhs I generate late in the afternoons. I also charge them at night at low rates and I manage my charging so at True Up I hit the sweet spot. In my case that is when I am a net consumer of energy but have a dollar credit and that results in only paying the minimum charges. I have batteries and that is what allows me to reach that goal.
I am not clear about what rate you are on. I am on Time of Use rates and I thought all recent solar NEM customers had to pick one of the TOU rates. . There is TOU-C and TOU-D and bothare TOU rates but TOU-C has an element of Tiers. There is also an EV TOU rate but it has higher peak rates at unfavorable times so I opted out of that into TOU-C.

I'm on tiered. All the TOU estimates provided by SCE when they removed the original TOU-D were not as cost-effective as tiered. My annual true-up cost is about $1,200. I've been running a monthly credit for the past 6 months due to climate credit.

Getting a battery is definitely an option but the ROI is an issue for me since I have other expenses.

I am on tiered rate with PG&E, similar to SCE's TOU-D . What specific tiered rate are you on? I don't trust the SCE or PG&E rate analyzer and since I track monthly bills by TOU period I did a spreadsheet with last years number and concluded that I would be optimal with a different rate plan. Last year I was a net consumer of one mWh of enery and had a small dollar creidt so it washed and i paid the minimum. You are in an entirely different situation with a $1,200 True Up. That does leave you an opportunity to spend some time and money to see how you can whittle that down. If a $5.000 investment could reduce your annual cost by $1,000 that would be less than a five year return after investment tax credit. It could also give you a hedge on inflation of rates that are only going up. Of course the best return is on energy conservation so perhaps a couple of hundred on an energy monitor would have some return. If nothing else it would give you more cofidence in SCE's net numbers.
