Re: What happends when you back feed a panel with to much AC?
The backfeed rule is pretty much just a theoretical possiblility, but needs to be adhered to for the tiny fraction of times where it might light a house on fire. I've never even heard of a situation where the main breaker trips do to an actual overload of the panel. The other practice we follow here is to position the solar backfeed breaker on the opposite end of the bus from the main breaker, thus minimizing the chance of both feed currents adding together.

Re: Split Phase vs Single Phase confusion
Yes we picked up on it and good luck, just give it time and think safety. It is a very hard thing to get a grid tie going on a hybrid. Most can't do it or never have tried. That goes for your installer also

I think you are "simply" a fantastic resource. You amaze me at your depth and kind heart. Live long and prosper!
Re: Battery charging
Plucka,
If you are going to invest in lithium do buy a controller with specific lithium settings, any thing else will probably destroy the lithium batteries and you will be burning money...
Re: Help choosing an inverter please
8 AGM batteries in parallel is going to be an expensive nightmare when they start failing. And fail soon they will. I say min-december, you will have walked them down to less than 50% ( I'm assuming you are running this all as a 12v system )
My suggestion - build a battery /power/ generator shed and park that gear in it. Firewall between generator and batteries.
Configure it to 48V with only 2 parallel banks. return the inverters and such and get quality gear. Plug your RV into it, and feed the fridge propane.
When house is complete, wire it to the shed too.
Re: Time to Question the 3 day Rule ?
My guess... In general, adding "new to old" batteries in series is the worst choice... Old batteries (especially flooded cell) tend to have higher self discharge--Vs new FLA batteries that have lower self discharge.
When you charge/equalize a series string--The new batteries tend to get "well over charged" vs the older batteries.

Re: Battery Monitor and/or Multiple temperature sensors
"when in doubt read the manual" It is in there to use only one sensor for a reason. If you think you are more in the know than the people who designed the system do it.
There has to be some sanity here, right?
You are doing the right thing Dicky!
