Why? Or you mean just cuz you have two units and each will display half the total?
SRNE 20KW parallel ASP journey.

Might be a Silly question but have you run them with an imbalance to see when and where it creates a problem?

Yea, because of two units.
Yea, I haven't had any issues. I haven't had the imbalance as high as the ASF because I don't have enough 120V loads. I had that up to ~75% imbalance, I've had the ASPs up around ~40% with no issues. It'd difficult to come up with 10KW of 120V loads on a single leg without really trying and moving stuff around.
Thanks

That would be a huge imbalance. I only have 100a service. Highest imbalance I've ever had was a measly 3.9kw.... Sounds like the right design/load panel setup if it's difficult to acheive a high imbalanced load.

Their both split-phase, there's no 2 phase.

Actually they only refer to two phase when you are wiring them up for 0° between phases.
180° between phases is referred to as split phase.

There's so much misinformation about phasing.
The first thing that you have to understand is what phasing is.
It's timing of separate sources.
Each phase (source) happens at a different time.
Power is created and used in single phases.
When you have multiple phases, they are separated by time.
To use multiple phases, you have to connect multiple loads. Each to their respective phase.
Two phase doesn't exists anymore, except for in a couple of very old factories.
It was abandoned and replaced by 3-phase.
The only options currently available around the world are single phase and 3-phase.
Split-phase is single phase with a center tapped neutral.
3-phase is 3 single phases timed equally at 1/3 of 360° (120° each).
PS: a Chinese manual is not the best place to learn electrical theory.

I am still working on getting to 1MW...
I am up to 2MW on the LVX6048 this year though!

Thank you for the explanation.
Agreed. I've been able to comprehend it much better over the years thanks to posts from you and others.

I still haven't figured out how to decipher how much I have produced to date.
One of these days I will figure it out.

The meter probably reset like the analog meters used to, back when quality vehicles were still built.

It switches to letters after 10k, I just haven't figured it out yet.

Maybe it's hexadecimal?

No idea, but maybe a combination.
Right now it says "C969 kwh".
42OhmsPA

C converted would be 43, so 43,969KWh definitely seems feasible.
C969 would be 43,393,639 seems less plausible based on the timeframe they've been in service.
~43.4 MWh if it's a combination. Very nice.

My system has made 80,286 KWH. I have used the growatt app since day one, it gives me the total of all inverters in one sum.
You Sir are a great teacher, thank you for this explanation

Yeah, it doesn't make sense, yet.
And that's just one unit.
Second unit is getting close to 10k, I'll see what happens on it.
I wasn't paying attention for the first one.

I never was able to get the app working. Which is how I found Solar Assistant.

Polyphase
Polyphase system - Wikipedia
"Higher-phase systems at the same phase-to-ground voltage have less voltage difference between adjacent phases, allowing a tighter conductor spacing. For six- and higher-phase power systems, the dominant effect becomes the phase-to-ground voltage instead.[5]
Six-phase operation thus lets an existing double-circuit transmission line carry more power without requiring additional conductor cable."
I suspect by 6 phase they mean 3 phase, with each sent as split phase on 2 wires. Any other angle would not have uniform voltage between all pairs of adjacent wires. 9 phase however should be 60 degree angle per phase.
"Multi-phase power generation designs with 5, 7, 9, 12, and 15 phases in conjunction with multi-phase induction generators (MPIGs) driven by wind turbines have been proposed."
"Since the rotation speed of a wind turbine may be too slow for a substantial portion of its operation to generate single-phase or even three-phase AC power, higher phase orders allow the system to capture a larger portion of the rotational energy as electric power.[dubious – discuss][citation needed]"
Quite dubious; 3-phase power has constant power delivery. It isn't notchy like single phase.
But you might have many poles. That could make 60 Hz at lower operation. Just like a lower speed motor.
"Once polyphase power is available, it may be converted to any desired number of phases with a suitable arrangement of transformers. Thus, the need for more than three phases is unusual, but higher phase numbers than three have been used."
And as I have noted before, given L1 and L2 of 3-phase, if you're lacking L3 (e.g. because you're in a condo or apartment) you can create the 3rd phase from the first 2.
well if it's hex it should be switching to D pretty soon
wait where do you get 43 from?
