Just 1 for now. I plan to add a 2nd in the future.
New Growatt hybrid inverter SPH10000TL- HU-US split phase
- Thread starter 1201
- Start date
The software update that was provided to me Friday fixed the above 2 issues. I was glad to know that the issue was with the inverter's software and not some configuration issue. They seem to be accepting my feedback.
For those interested, I was able to upload the new software to the inverter using the attached document that they provided.
I will now attempt to get them to remove the 36% minimum discharge limit on Time Of Use.
Thanks for the update. Good to know they are working on the software.
How's are you liking the inverter so far?
It has been pretty good so far. Happy to have those above issues fixed. I think the value is decent --- It would be nice to have a larger "pass-through" capability but for my use case I think the cost/features ratio is a good balance.
Copy. Thanks for the feedback. I don't know if I asked but data on the app updates every five minutes?
Why is the growatt SPH 10000TL-HU-US considered an all in one?
I read something about needing another device like the SPH 10000TL-HU-US if wanting to add batteries?
Maybe the info was wrong. I'm looking for a 10kw to 12kw all in one grid tie inverter but wanted everything in one box.
UPDATE: Sorry, I goofed on the model in this post but leaving it as it is so as not to confuse readers. The next posts clarify.

I think this one has everything in one box to do backup split phase power, but maybe you are asking about the ambiguous cases of hybrid/AIO
Some definition of AIO is inverter/charger plus solar charge controller. This lets you exclude grid transfer device (called a Microgrid interconnection device) and neutral forming hardware if needed. MIDs will often include the neutral forming transformer. Sometimes emergency power will require neutral forming transformer and ATS (the growatt MIN? needs it. The ? Is because I don’t know exactly which one).
And the systems that aren’t as “all in one” are still useful to some customers without all the pieces. For instance in Enphase you don’t need their $1500 MID to get self consumption on a battery; it is only needed if you want EPS. And this is sufficient to max out the ROI under a non net metered grid tie setup with battery (IE California NEM3). Since the grid going down 48 hours a year may not be worth $1500 up front to fix

To be clear, yes everything. The rest of his discussion is referring to other products and irrelevant to the sph 1000TL-HU-US.

The previous message said “this is an AIO” and it wasn’t clear that OP knew that AIO is not universally consistent. Even within Growatt, which they have multiple of on their shopping list, this truly all in one one, and the ones that need MID, and the ones that need ATS-US ats plus AT combo.
Thanks for the information. That was a typo. The model I was looking at was the SE11400H-US.
I've been searching for weeks for something that's in the CA certified list for AZ use with little luck.
I'm trying to find a grid tie 10kw inverter that is a true all in one, 240vac, and around the $2500 or less mark.
I'd like batteryless use initially then would add batteries. I thought this could be the one until I read around the optional requirements to use batteries, generator, etc.
I don't know anything about the Growatt inverters. I read that in one of the documents or specs I was reading about the model I posted. I tried finding where I saw it but wasn't able to.

There is a lot of information to digest and decrypt but the sph10000tl hu us is on the list, and it does not require a battery to operate. You can start off without batteries and add them later
Have you read the manual?

It doesn't have 9540 batteries yet so there's a bit of dice roll involved in how much a 9540 system (which would require Growatt to decide to list a battery of their own, or more 9540 DC ESS batteries to come on the market) would end up costing.
-We don't know if 9540 is a requirement where they live
-some people who start without batteries are adding batteries without telling the ahj
-if he uses lead acid batteries he is not subject to 9540
I think we are worrying about a non issue

IMO my pedantry is consistent with what’s smart in my state, and it constitutes a large % of people who might be googling for info on forums.
This is a risky proposition because batteries are very easy for POCO to detect with behavior on smart meter (in the absence of being pretty smart about the settings, which I haven’t seen discussed on this forum) and POCO have ways to demand inspection by AHJ.
This is only true in some jurisdictions.

This is exactly how I plan to do my install, only I'm using 2 of these inverters, and maybe batteries later.

I'm in Arizona and I can tell you that I've checked with my local power company here (SRP) and they just said that everything needs to be on the list, Batteries, Inverters, and Panels. I asked specifically about 9540 and I was told.
"I can’t speak to what other inspectors are requiring so I’ll move to what I can respond to. UL 9540 is not a requirement for any battery, although the battery can be UL 9540 certified depending on if manufacturer decides to do so. We see both UL listings, batteries in our service territory can be either UL 1973 or UL 9540, this is up to the contractor. In addition, we see many battery/inverter combinations from different manufacturers, our only requirement is that both be listed on the CEC in order to be available on dropdown for our PowerClerk entry program. As long as inverter and battery are on the CEC list, and you’re following manufacturers recommended install, you should be good."
Although this was about a year ago... it could be different now.
First, I'm in Arizona. Second, I goofed up when I posted. I seem to have mixed up my notes from searching for too long.
The inverter I was looking at was the SE11400H-US.
I believe this is the page I was looking at that mentions needing a growatt BI-EUSGN backup interface if wanting to add geny and batteries.
However, if I'm reading that right, this BI-EUSGN simply acts as a main transfer switch if you have a more complex system when you want to isolate everything behind the power company. I'm not sure.
I quickly took a look and that device was another couple grand which is why I stopped there since it was not 100% clear if this additional device was in fact needed since the SE11400H-US is called an all in one.
I have 42 panels, 10.5 KW and when I replace panels, I'll probably have to use higher power ones hence the slightly larger inverter.
However, I'm grandfathered in with APS for 10.5KW max.
I'll use the inverter without batteries at first but would be adding batteries over time to become less and less dependent on the power company while still being grid tied. I'd like to get an inverter that will give me battery choices and do already have a generator but it's connected to it's own load with a bypass switch so really, out of this mix.
The one thing that makes me nervous about using Growatt is the marketing material going 'optional' this and that a lot which doesn't make this inverter sound very all in one.
Note, the URL I share DOES show 9540 certified.
UL1741, UL1741 SA, UL1741 SB, UL1741 PCS, UL1699B, UL1998, UL9540, CSA 22.2

Why are we talking about a solar edge inverter in this growatt thread?
If you are looking at that inverter please start a thread on it. Thanks.
Aw jeez. Yup, As I said, my notes are starting to get all mixed up at this point. My apologies.
The only Growatt I've looked at so far is the MIN 11000TL-XH-US.
Again, apologies for the confusion.
oh ,ok lol. no worries.
clear your mind and start here
THIS is what you need, and THIS is all you need.

Take a look at the Solis S6's ( S6-EH1P11.4K-H-US )
Inverters that support high voltage (400v) storage batteries
Hi guys, Second post. I'm in Japan (100v 60hz) and am researching the best inverter brand and model to buy for a DIY solar build. I intend to connect a Leaf 24kWh battery to it for home storage. I'm a member of Dala's EV discord group but have additional questions. So far I've been able to...

Nice, I finally two potential candidates. I'll do some reading and see which might be better.
Over time, as I change my old panels out, I'll have to put higher wattage ones in. I'd like to keep that for the house/batteries as I'll need to send no more than 10.5K to the grid which is my agreement.

Has anyone seen a video or review of this model besides the stuff put out by Growatt?
The Solis uses an hv battery which is going to be a lot more complicated and/or expensive.
There is only one real choice, sorry.
