Zero-export inverter, not backfeed to the grid

Ok thank you. Is this called grid assist?

It's called SUB (Solar Utility Battery) mode.
But it works similar to grid assist. Just without using Battery to assist. Only Solar is assisting the grid.

It can pass the grid through to the loads.
It can blend grid and solar to share the loads.

So this means I can connect ac out from mpp 11k to the grid mains in the house?

How does it not export? Shouldn't it be a clamp on the mains so power goes just in one direction, into the house and not out?

No
The output should never be connected to the grid.
Output is for your loads.
Input can be fed from the grid.

Ok I see. Is it correct that you can connect the ac output on the Sun GTIL 2000w to the grid mains in the house? https://www.amazon.com/Inverter-Limiter-240vac-45-90vdc-190-260vac/dp/B0BL22Z567

Does it exist an inverter similar to the Sun GTIL 2000w but with more power like 11kw and also can charge batteries?

Yes, that's a grid-tied inverter.

That would be a hybrid AIO.
They have features of both, a grid-tied and off grid AIO. They also come with the price of buying both, almost.

And also zero export like GTIL with CT clamp?

Do you have an example of one low budget around 10kw?

What are your voltage requirements?

230v 50hz in Norway
Battery voltage 48v

Look at Deye products. They're top quality for a fair price. And will do everything you want. Their products are also sold under the SunSink brand. Slightly higher price but better firmware and customer service.

Enphase? IQ6/7 micros and one of their IQ combiners w/CTs to manage it. Set it to a no export profile and you're good to go. It's scalable to 48kw doesn't require storage but can add up to 40kw of storage. You can also take their free course on their website to be certified and everything you install yourself will still carry the warranty.

Storage is very very expensive.

Yeah, but if all your wanting is a zero-export system with no storage it's a decent option.

Anbefaler kjøp av Deye. Meget bra kvalitet.
Håper du bor sør i Norge hvis du tenker på solar ^^

Zero-export inverter, not backfeed to the grid

Is there a inverter that supplements/ties with the grid, but does not ever backfeed the grid? When I search it seems this is called zero-export inverter, is that right? Or is it called limiter? I see it's something called zero export to ct, but I don't know what ct means? I just wanna use solar...

Ok, but can I connect the MPP 11k to my loads in the house fusebox so it gives power to all the power outlets in the house?

You have to run the grid to the AIO first. And then your loads connect to the output.

Ok thanks. Then it's not possible to use the grid for the loads? If I want that I have to get hybrid inverter like MPP mki 10kw?

timselectric · Feb 5, 2023

That inverter can pass grid through to the loads, if needed. It has a built-in transfer switch. And can switch between inverter and grid.
