Without definitive terms we misunderstand each other.

Agree.

Which is precisely why the use of the term "hybrid" to distinguish whether an inverter is capable of bi-directional energy flow with the grid makes little sense, creates confusion and misunderstanding. There's nothing "hybrid" about that particular feature. It's not a mixing or blending of anything.

I did put in a huge pic with the definition :LOL: With a red box. With the link.

That's not a technical definition. It's just a product statement.

I've been trying to find a definition in the literature but I'm not so familiar with searching electrical engineering papers (I'm not an electrical engineer).

There are papers where the term is used, for example many papers like this one talk about Hybrid multilevel inverters (binary, trinary etc):

In these papers the term "hybrid inverter" refers to the combination of various technical means of producing near sine wave output forms / reduction of distortion from variable DC voltage input(s).

I accept its use has been mangled. It happens a lot. Heck, "shock absorbers" in cars don't absorb shocks (they just dampen the motion of the spring), "coolant" added to cars doesn't help cooling (its purpose is simply to lower the freezing point and raise the boiling point of the cooling fluid, indeed "coolant" reduces the heat transfer capacity of the water its mixed with), and car "radiators" don't use radiation for heat exchange either.
 
When a newbie comes on the list and mentions "hybrid inverter" I ask for clarification or just move on.
IME its mostly newbies that use the word and it means whatever they think it means.
It just increases the cognitive load on those trying to help.

Great to hear about Phasing, I'm residential, but I lost my garage to fire, and the Phoenix is a 25x25 with lift, compressor, welder, lathe. etc currently split 240 from the pole, proper3 phase would make for better machine tool choice, thats all

I have a pad area 6'x25' next to the garage. great place for batteries and I am open to any electron storage system.
some kind of battery farm can grow there, lead acid , salt water , whats cheep and reliable? No need for a pretty fire hazard bolted to my bedroom wall

LiFePO4 is the most stable nowadays.
But it needs climate control. Can not be charged under 0 Celsius. And best to used under 45 Celsius.
Can be put outside but then it needs a heating and cooling system (like Tesla has in the PowerWall)

I'll grab hard data, and make a proper list of draw of course, but I have nuthin close to the AC, its a newish 2 ton. I assume if I size to turn that on with all the other notables running, it will succeed.

Yes, solid plan to size for that. For that you will need the info of how many W is this unit uses.
Also if it is not an inverter AC then it will have a huge inrush when it starts.
That is the most important information because the inverter(s) have to have enough juice for that.

I wouldn’t go so far as to call this a technical forum. Certainly there are highly technical activities on here…

this is a DIY forum where learning and helping others do a project safely and adequately…

there is a forum for definitions on here.

I am a noob to BMS etc,
pretty familiar with forum jabbing
I was gonna say yesterday, looking at post #9, Looks like I'm building an Inverted Hybrid.....

Sometimes terms define, sometimes terms are to market. sometimes, simple inertia

What it seems you want is an Off-grid With grid support (Without solar) system ... or short it is called an UPS system ;)

So the Pad I mentioned is, by its location, essentially in permashade. So, I can assume ambient temps of 35~95

What can live in those extremes ?
 
He He

My first troll post, gosh they grow up so quick
my dad used em for his PC's

SInce it may very well lead to it, the 13 foot x 25 foot due south facing steel garage roof.

Were that to be covered with panels, would it be enough to keep the batteries up?

say I'm using 1200/month high side

close? not even?

My vote, 3x Growatt inverters paralleled into 3phase, critical loads panel and a battery from big battery.com and youll have a UPS

My turn to bite

is there really a site called bigbattery dotcom?

I was about to hop over...
