Did you get permits? Are you being inspected? Did you enter into a net metering agreement with your electric company?
It’s my understanding that a permit isn’t needed unless you are feeding into the grid. These inverters have limiters that prevent that. Engineer775 when installing a SolArk he said something like when using the zero export then permitting/net metering etc isn’t required. Might be different depending on the area.
I would think they'd still want it documented whats what and where and would want documented proof that it was installed properly, Kinda hard to argue with the safety aspect of that. Anyway, its not like i'm code enforcement. I'm just here because it interests me and I like learning new things.
Yeah they want it documented. If they see solar on your roof they automatically want to look inside. They could simply say they seen backfeeding even if it wasn’t happening. I mean you could try to tell them to prove it but they would just shutoff your electricity. Imo it’s no different than wiring up a generator But not everyone can do that safely either.
Is this somewhat unique to this model/brand SCC, or can all SCC be set to power the inverter first, then battery power with excess?
It's pretty standard for AIO's.
If you read trough the whole thread, the whole point is to NOT have an inspection or draw permits. It's also not that I have any problem doing things to code and being inspected as such - My goal is to do everything better than code. Code is just the maximum younare allowed to suck and get away with it. I have no desire to have my house nor shop burn down.
If any inverters reboot/restart voltage is met, then it should be able to power the loads from pv/charge controller and excess will go into the battery.
I know what code is for. Its not always just about safety for you and your property. It's also about safety for those around you. Neighbors, linemen, etc.
Anyway, Like I said, I'm not code enforcement. I was just pointing out that there are ways to do it without the technical term "grid tie". I also understand that may take more of an investment.
"...more of an investment." It's interesting that you just posted that statement. I just was doing some quick math as you were posting because that is another big reason to do it the way that I am. My neighbor had a 25KW system installed through one of those big companies about two years ago. He paid $40,000.00 back then. At today's prices, I should be able to do the same for around $18,000.00. And I don't need as much power as him. That's a significant difference.
Sounds about right. Paying someone to do it is usually more expensive.
Your gonna like that Iotawatt. I check it every day. The graphing is really good. You can adjust the time to whatever and see what happened.
