Export Limit with Growatt inverters?

[Cheap 4-life]

I admit that looks promising.

But that is a single-phase 240V model, correct?

I have not been able to find any manual for the MIN XH-US (240V/120V split-phase) model…

In any case, welcome to the thread !

If it’s a grid tie inverter then it doesn’t have to be splitphase or 120v single phase.. Loads continue to use the grids transformers neutral to acquire 120v.. the grids meter only has one Ct in it and doesn’t use neutral at all in its calculations, nor does the meter care how much power a 120v load is using because it reads the homes power via the 240v sinewave.

Single-phase zero-export inverters may well function that way, but I doubt they’ll ever get UL-listed for use in split-phase service feeds…

Tried those links - they all lead me back to the same page…

Just tried the link. It takes you to the technical specs. A the bottom there is a download section. Under Manuals there is three part download of the manual.

There is also a spec sheet, installation guide, and certificates area.

The page does not load well on mobile. I had to request the desktop site. From a computer it loads fine.

As I read more about the Min series that I have linked I really like them. All except the Battery being the High Voltage DC. Deal buster for me but man they look good on paper. The SPH is missing a lot in comparison but does 48V batteries.. Hrmmmm..

It’s gotta be only a matter of time before they introduce a 48V version of the Min.

What are the main features you see the Min supporting that the SPH does not?

comparing the 6000 in each to make it apples to apples..

	MIN 6000TL-XH-US	SPH6000TL BL-US
Max PV Input	12000W	8000W
Max DC Voltage	600	550
Start Voltage	50	150
Operating Range	50-550	150-550
MPPT Inputs	3 (2 strings per for a total of 6 strings inputs)	2 (1 string per for a total of 2 strings inputs)
battery voltage	360-550	42-59
Max Efficiency	98.4	97
W/H/D Inches	15.75/22.41/6.98	26.3/22.2/7
Weights Pounds	32.3	73.85

Just a quick comparison and what I see as the main differences.. I may well be missing stuff or misinterpreted.

I got the following Pricing in Canadian
GRO-3800TL-XH(3.8kW, 240VAC, stackable to 6x)-$1106
GRO-6000TL-XH (6kW, 240VAC, Stackable to 6x + WiFi module + Tigo transmitter)-$1526.
GRO-10000TL-XH (10kW, 240VAC, stackable to 6x + WiFi module)-$1855.
GRO-ARO 9.9 (9.9KWK, 360VDC battery for XH)-$9108.
SPH/XH ATS 5000T (25A, up to 5kW secondary circuit)-$674
SPH/XH ATS 11400T ( 50A, up to 5kW secondary circuit)-$897
SPH/XH ATS SYN 200TL (200A, up to 10kW secondary w/ smart meter)- $1947.
Smart Electricity Meter SM-US-20- $267

They are from https://microgreen.ca/growatt-residential/inverters-overview

So for me.. Looking at the 10000TL-XH
I would also need an ATS, so maybe the SPH/XH ATS 11400T. Not sure the difference between the the 11400T and 5000T as they both say up to 5kW Secondary circuit.

If I get my permit from my hydro company I might skit the Smart Meter. I am not sure what it gives you if your able to export to grid.

I found this diagram helpful for me to wrap my brain around the wiring:
View attachment 74032



I took this from Growatts installation guide found here: https://www.growatt-america.com/show-9-633.html
page 29

I need to read more about the ATS and the batteries they support.

I cannot see the difference between the 11400T & 5000T ATS. Also the diagram does not show a main bonding jumper in the main panel.

Hi, with my SPH4000 I got a CT sensor with RJ45 interface.

Does anyone know which pins on RJ45 are active?

It’s gotta be only a matter of time before they introduce a 48V version of the Min.

I'm assuming still no word on this (48V version of the MIN)?
