Because I basically have no other way to install it for code reasons, and because I'd like to backup the entire house.

Hmm, not sure how this gets around being limited to 100% and 120% rule (I didn’t look at the load side rules for 2008)
Another thought is going to 2x200A rated service disconnect and somehow using that to get 200A of capacity from the service while also having 200A of inverter. Since it has a 400A busbar.
I guess 2008 also doesn’t allow you to use Power Control System to reduce the backfeed current used in the calculation.

It gets around the 120% rule because it's not a backfed breaker. It's simply feeding the panel thru the main breaker. Local AHJ bought off on the plans and issued me a permit, so I'm not gonna look a gift horse in the mouth. Its certainly not the most elegant solution, but it should work.

A few things to keep in mind when looking at the whole 200A vs 100A passthrough subject:
A few things to keep in mind when looking at the whole 200A vs 100A passthrough subject:
- The goal is usually to have a flicker free transfer to inverter when grid goes down. If this happens you won't find out grid is down, and therefore you won't manually manage peak loads!
- For a DIY install where you keep a close eye on things 200A may be fine. For a professional install fot a customer who just wants seemless back power 200A will likely NOT work. It's really not cut-and-dried for every install.
- Often it's not as simple as "just running the 200A service through the inverter." Often that actually consists of getting a disconnect scheduled with the power company, adding an outdoor knife disconnect, sometimes it means you need to do a line side tap, and if you want a bypass/backup option in case of inverter failure you will also be looking at 200A equipment if you go with a throw style transfer switch for bypass. (Although you can go with a main to bus interlock.)
- In my experience is actually often easier to transfer critical loads to a new panel, than it is to revise the whole service!
- At the end of the day it still comes down to you looking at what is the right setup for your specific needs
There is a proposal to update Indiana to NEC 2023. There are committees working on that now and I expect this will happen perhaps by early 2025.
There are some nice things about NEC 2008, though. It lacks the RSD requirement for solar strings, for example.

that's awesome.
.Try adding your serial number on the website, via pc. It should work that way.

Which app are you having problems with? The local shine tools app or the remote shine phone app?
With the latest version of the local shine tools app I don’t use the scan feature, it doesn’t work well with my phones, I have the serial number typed in “notes” and copy/paste it into the app. Also, you need to use the inverter serial number , not data logger serial number. What error do you get? Screenshot?
Do you have the battery communicating with the inverter? Or are you using it open loop?
RS485 Worked once configured for Growatt on the EG4. Also Tried CAN but that did not seem to work correctly.
So I am trying to use the Shinetools app as it shows in the manual. It just tells me the serial number is invalid every time, so then I cannot proceed through the process. I am using the right serial number and also tried the other ones on the unit but same every time. Also yes typed it in manually.

Mine shipped and arrived fine. Same manual as is available online. I'm probably still months away from the install, so good to see some other installs first.
have you downloaded shinetools? its very easy to connect to the inverter from shinetools. now, its a little bit of a process
- connect to shinetools while on the internet.
- enter your password
- switch to the inverter's wifi
- make your changes, for example connecting the inverter to your home wifi
- disconnect and now you should be able to see your inverter in shinephone
Yes, two things appear wrong.
1. In the Shinetools app when selecting my device it asks for serial number but it will not accept the serial number as correct. Neither the device or the datalogger.
2. There is no visible wifi network to connect to.
in shintools in the first page it asks you to log in.
after that it asks to select a "debugging tool"
are you choosing direct wifi/bluetooth here? or something else?

I’ve noticed that the ShineTools app has started verifying that the serial number entered is a valid inverter for the inverter type you are trying to connect to - I tried to connect ShineTools to my min-us inverters using the SPH inverter selection and get there error you are getting- they probably have either not updated their serial number database or have a bug in the app. I suggest CALLing Growatt support, in my experience you will get much faster fix that way. I’d also contact Self2solar, the individual I was dealing with in April definitely could make things happen within Growatt quickly- he did some stuff for me on the last aro battery I bought.
Growatt support number:
Yeah the manual says to choose direct wifi/Bluetooth, so I do that then select device.
Ok great . Once you do that it should ask you to connect to a network correct?

The newest version of the app does not do it that way, I assume he has the newest version. I have the newest version on one phone but hate it so kept an older version on another phone.
Ok when I choose min th it asks to connect to a network but when I choose sph it brings up the camera to scan the serial or enter it manually.
I think that's the problem @upsideup is having? It doesn't accept the serial number?
No bueno

My phone with newest app does that for both SPH and min-us
