I wonder if the midnight unit will be capable of running as an off-grid inverter, with grid interactivity as an option if a person chose not to do any export at all
Sounds like you should buy a "15k"The SA15k $6.8k. IMO, that's not much of a reach from ~$5.5k and in my situation, that extra $1.3 buys 200amp passthrough and proven performance. In my situation, I 'might' be able to get away with 1 15k but it would take 2 MNS to get 200amp passthrough, but yeah, MidNite has a reputation for top notch products and service.
Add a Chargeverter to help charge batteries off the GW.Rosie $3.3k ac coupled to growatt 11.4kw for $1.5k, 18.4kw daytime inverting capacity, 7kw nighttime, and I suspect that Rosie can pull power from grid and supplement with battery to get above the 7kw total capacity
just exploring different configurations/alternatives
MPPT Disconnect is on the left side of the machineI didn’t see battery nor MPPT breakers.
If totally off grid, might be a better choice to use something like 4 stacked EG4 6000XPI wonder if the midnight unit will be capable of running as an off-grid inverter, with grid interactivity as an option if a person chose not to do any export at all
I’m selling a 15K, New in box for $5800 +~$250 shipping.I'd be in for a second sol-ark at $6k. It might not be the unlikely actually with the recent solar slowdown.

I'm curious about this and not sure I understand. What's the chargeverter for?Add a Chargeverter to help charge batteries off the GW.
Interesting idea.
the growatt is a grid tie inverter that can couple to a hybrid inverter. just looking at ways that one could use a rosie and have similar capabilities at the mnaio at a similar price point.Sorry I really don't know what you mean by AC coupling. Is the Growatt 11.4K a grid tie inverter? I don't know what you're getting at, but like my title says, I'm a noob. Are you saying the MN would be connected to the grid, and the Growatt to the MN, or vice versa?
My point is by itself this new AIO is from MNS, not known for being cheap. So with all the features this thing has, not just the inverter and MPPT's, I just don't think it'll be under $5K.
You just have much higher idle consumption, lower efficiency and less featuresIf totally off grid, might be a better choice to use something like 4 stacked EG4 6000XP
Does this mean you are confident and switching over to the Midnite unit?I’m selling a 15K, New in box for $5800 +~$250 shipping.
No, don’t need GT inverter. Going off-grid.Does this mean you are confident and switching over to the Midnite unit?
Possibly both, maybe neither. A couple of the new nhx hybrids from Watts might fill the bill for the price of one MidNite or Solark, as would a pair of the also new to be released stackable SRNE that 420 has praised.Sounds like you should buy a "15k"
Are you trying to convince us or convince yourself?
What "features" does one need if off grid?You just have much higher idle consumption, lower efficiency and less features
Chargeverter to use excess AC power to help charge the batteries. You wanted AC coupled with batteries. Rosie for power when the sun doesn't shine. Rosie DC charger can do 120A, but with large battery banks you will want more charging capacity. At 120A charging, that isn't quite 7Kw. If PV is 11K, you can capture the other 4Kw if load is low.I'm curious about this and not sure I understand. What's the chargeverter for?
Oh, I see what you mean now. 120a charging is quite low. I'm surprised at that.Chargeverter to use excess AC power to help charge the batteries. You wanted AC coupled with batteries.

Off grid features, probably not much, the only ones that come to mind quickly are programmability for dump loads being native, or accepting AC Coupled inverters easily. Or can the 6000XP accept AC Coupling?What "features" does one need if off grid?
You gain more MPPT's, that can easily cover higher idle consumption. The advantage is redundancy, you have spares to keep going.
You are thinking along the lines grid backup and grid assist. None of those things apply with total off grid. You need high output to cover those surge loads, plenty of charging capability and backup power with multiple units.
Remember that the 15K is actually 12KW except for during the day.SolArk 15k for $6800 vs ~$5500 for a new unproven MidNite aio with less capability. My enthusiasm for this new unit is starting to wane.
Yikes! Out of my pricing horizon. Not that it tain't pretty.Ballpark... $5,500. This should be compared more with the Sol-Ark 15K which is quite a bit more I believe.
We are still pricing things out.
boB
Not entirely.Remember that the 15K is actually 12KW except for during the day.
This is why I would like to start referring to the inverters by their Current capabilities.Yes with the SolArk at 275a rating, you can technically get the full 12kw (rated) output down to like 44v. And if battery voltage is at a more modest 52v, then it's capable of 14.3kw.
Not totally off grid, I just do not want anything related to Export, I do not have an interconnect with the PoCo. I want to store all my energy on site ... BUT ... I want to have grid interactive and pass thru features such as being able to switch back to grid automatically when the battery drops below a set SOC, or the ability to load support with grid (features like the Schneider XW Pro).If totally off grid, might be a better choice to use something like 4 stacked EG4 6000XP
