I'm in California and looking to upgrade my solar array prior to NEM3 going into effect (4/14/2023).
My system is 3.71 kWp and covers approx. 50% of my energy needs - leaving me with a $400+ true-up bill at the end of the year.
The current system comprises:
Inverter:
1 x SolarEdge SE5000H-US

Power Optimizer:
13 x SolarEdge P320
https://knowledge-center.solaredge....rame-mounted-power-optimizer-datasheet-na.pdf
Solar Panels:
1 string of 13 panels - Hanwha Q-Cells Q.PLUS BFR-G4.1 285 (285W) Solar Panel
I discovered that I can upgrade my inverter at any point while remaining NEM2 compliant, so there's no particular rush at the moment. However, I can only increase the size of my array by 10% or 1 kWh (whichever is met first) without triggering NEM3 billing - Unless I get a plan approved before 4/14/2023.
I've got the following questions that all the googling in the world can't seem to provide an answer:
- Does this inverter REQUIRE P320 optimizers for each panel?
- Can I add a second string of higher-wattage PV panels to this inverter without downgrading to the lowest string wattage?
- Is Sol-Ark my best option for AC coupling to this inverter for the purpose of battery storage, or is there another better option?
- If AC coupling is the best option, would it make more sense to add a second string to that inverter vs. my current grid-tied inverter?
- If planning to AC couple a hybrid inverter with a separate array - wouldn't this technically qualify as an off-grid system and, generally, not fall under municipal code until/unless it is AC coupled?
It seems that I may be missing some basic concepts, so I realize these may be silly questions to some. Feel free to point me in the right direction if you know of a resource that helped you get the basics down.
Thanks for your help!
