In this case you would have the "micro-grid" setting checked.
Which still doesn't explain why the actual peak shaving setting would cause an AC charge.

Ohhhh right there's a setting they changed to make it not do that. We set it to zero so I only force discharge and do schedule charge if necessary. I forgot what the setting was called but if you call them they can change it.
Oh right, I think we changed that setting as well haha
I need to figure out what settings they changed because we changed quite a few settings on the first day or two and now I forgot about them. Need to get back in there and see what they did
Wait isn't that ideal? If solar can't cover my loads, I want the battery to cover the remainder. I'll read through your posts again. Not sure what's wrong in the picture.
It's not ideal in my situation. However Ideal or not it's still not following the settings. I do not have peak shaving enabled, so it should not be shaving. I've not seen any other explanation of why it's using batteries. The only way to get it to stop is limiting it based on some other setting such as "charge first".
Two situations where this is a problem:
- A utility has a demand or TOU charge. I don't want to use my batteries to peak shave my 1kW constant load overnight when that means I'll be out of juice to cover the 5kW load when it turns on in the morning peak before I have enough solar to cover my load.
- Just wanting to save as much power as possible for a potential outage. If I plug my EV in and charge overnight I'll be completely out of storage by midnight.
Regardless, settings should do something instead of nothing or there's no point in having it on the screen.

I think either @Will Prowse or @Gavin Stone (or both) did a load on one leg in their video and it held up very well. Something like 75a on one leg and 14a on the other. I think that was Gavin's.

I think it hit 72 amps in my test from what I recall. Which is massive really.

Please explain this further.

when I got my inverter last October, the grid peak shaving feature work like what says in the manual, but after couple update the behavior of grid peak shaving changed, i did all kind a test and i figured it out that it will charge the battery with ac, if the setting of kw is higher than the load of the inverter and it will charge it with that rate. I believe it does this to make sure there's energy on the battery for future high peak load...

if everything is unchecked the inverter will be in Self Consumption mode, which the inverter will provide power to the house load with solar then battery (if solar production is not enough to cover the house load) then grid will provide power to the house load, if solar and battery is not enough.
if solar is more than the house load, it will charge the battery and export to the grid when battery is full.
if you don't want to discharged energy from your battery use (Charge PV first)(Charge Priority) use the timer when you don't want to discharge it.
pm me if you need help.

I think that's my key issue right there. I personally want to be able to do everything myself without having to call up a support company to manipulate settings into what I want. IMO, the manual has too many places where it falls short.
Just like you're saying, here is most of what's said about peak shaving in the manual (1.3.0, this one just popped online recently)
Used to set maximum power the inverter will draw from the grid. Making the assumption my inverter is working "as intended" this just doesn't match reality at all. I started typing up a whole slew of examples but then I just got too wordy. Point being is I'm 100% certain the interaction of peak shaving with the other modes is not explained in the manual.
That way of wording it actually makes sense and allowed me to recognize this section from the manual
This independently makes complete sense, thank you for pointing this out.
It's very possible I'm the problem when it comes to the manual. If I'm being dumb someone just tell me. I've been known to zone in on the wrong thing.

Here Is some more info im sure you guys will appreciate.
This is all useful.
From the HybridSettingGuidance:
Are you able to share the video or guidance for this function? Most of my confusion on the operation of this unit is centered around this one setting, so I'd love to learn as much as I can on it.

So here's how I would describe this function with my current understanding:
"Peak-Shaving is an AC charge that is limited by maximum grid import. It is useful in situations where the utility issues a demand charge based on peak grid import where there may not be enough battery capacity to cover a high but periodic load over the full operating period without additional charging while the load is off."

It is useful in situations where the utility issues a demand charge based on peak grid import where there may not be enough battery capacity to cover a high but periodic load over the full operating period without additional charging while the load is off."
I could see where commissioning can be a good thing if there is a problem or you cant figure things out and need help. So I'm wondering, will it work right "out of the box" when I get mine in a few days? I wonder if these updates from early on will have been made before it comes to me? If it works fine being used "just off grid" with "AC input only" when needed, and I will not need to commission the unit unless there is a problem?
I'm not so keen on some one making changes to the unit with out telling me first. Not so wild of leaving it connected to the internet all the time.

"commission" is a fancy word for "setting up" the inverter for your particular situation. You will need to "commission" it.
