DNEA inverters

[Flouw]

Good day all. 

I stumbled on these inverters. 

Does anyone know them or recognize the casing from some clone?

Grid tied with CT coil. And it being 24v sounds rather nifty. 

Im trying to help my parents get a system going at the holiday home. It doesnt have huge power draws. But the power is out alot of time besides load shedding.

That looks like an interesting little budget grid-tie inverter.
I must maybe try getting one and testing it out for budget installs.
That price looks pretty good for a small grid-tie system.

The specs and interface does look impressive. And it being 24v makes the battery options limited, but much cheaper as a load shedding essential kit aswell. With the benefit of pushing back into non essentials during daytime

 

I have found a video mentioning Sorotec Revo inverter that looks similar. End of the day. All of them comes from China.

You can come test it out in my house... hint hint nudge nudge.

As ill have to build the kit and test anyway before i move it to the holiday home. And the fact that it can also work without battery. But can add at a later stage makes it even more attractive.

 

Lets hope someone else has more information or experience with mentioned inverter.

Seems like a new South African Enterprise that is affiliated with or owned by https://chintglobal.com/ and their brand name is used on this range of Chinese products.
On that global site it seems that Chint has quite a few suppliers themselves

found one on china website with specs

No mention of anti-islanding protection, not too much of an issue for DIY or small budget installs as anti-islanding protection can easily be added.

Looks discontinued, so maybe a dodgy website here in SA or they are dumping stock to SA

Looking at the model number and doing a search brings up a sunways one, which is the same inverter branded in the Manual as Sorotec.

 

From what I could quickly pickup is that other forums mentions it under the sorotec banner without major complaints.

Here are my two worthless cents about this:

1. Grid-tie doesn't make sense to me in SA.
2. Grid-tie makes even less sense on small inverters such as this 3KVA.
3. Holliday homes are often standing empty for long stretches of time.  I would certainly not put a lot of solar panels up on the roof.  The likelihood of theft is enormous, especial in the current situation.
4. For the above reason, an inverter with  a 145V MPPT should be sufficient.
5. 10K I regard as expensive.  Especially on an unknown product.  For instance, you can buy the Kodak OG3.24 at the Power Forum Store for R 9315, and they show plenty stock available.  We know that Kodak is not a clone and although I didn't compare the specifications line-by-line, I would expect more or less compatible specs.  The OG2.24 also uses a high voltage MPPT.

But I will not stop you from buying a DNEA.  We need people to be riskier with their money than what I am, and then report back.  Only this way can we expand and grow and separate the Good from the Bad.   Who knows, maybe DNEA will become a household name in 3 years time.

From the looks of it Dnea is just a rebrand of the same inverter and not per say a clone, as it looks like the Sorotec is a well known name actually, but I only did some quick checks.

Normal grid tie does not make much sense in SA at the moment, you are right. Like the Solis pure grid-tie type inverters, as we do not have a decent stable day-time power supply.
There are in SA and here on the forum some clever folk who use solis type grid-tie inverters in very creative ways and I have not heard any complaints yet.

BUT!! - A hybrid grid-tie to me makes perfect sense no matter how small it is as you can push your excess power to your non-essentials seamlessly.
That's why the sunsynk/deye inverters are so popular every bit of power you can harness counts in my books.
Remember not everyone are high power users so there is always room for these smaller type hybrid grid-tie inverters.

As soon as I get my hands on one of these I will put it through it's paces and then see if it is worth the sub 10k price for a low usage scenario.

Now look at this 100kW grid-tie system
Makes my sunsynk grid-tie system look tiny in comparison

I just love your 1st 2 points.

I am sure the municipality will be very happy as well....  to be able to buy some electricity back at next to nothing rates, to then sell to the average Joe at the full rate.

Selling electricity does make sense for large industrial sites such as manufacturers that might not operate on weekends and thus have Saturday & Sunday solar over production.  But for everyone else, they can shove their misery few cents/ KWh where the sun ain't shining !!!!  Especially with 1000s of rands worth of bi-directional meter costs and monthly levies.  Boy, these guys are sick.

Has anyone found more information on these DNEA inverters? 

or an supplier? 

load shedding is getting worse by the day.... even though my battery and inverter is capable of doing the 4 hour outages with ease. the non essentials is the issue. getting laundry done is becoming an issue. again. the battery is able to run the washing machine. but that dips deep into the battery capacity over 4 hours of load shedding.

You should rather have a look at the LUXPOWER ECO Hybrid, a bit more expensive but at least you know you are getting a decent inverter with good Support in SA.
It has all the same functionality that the deye/sunsynks have but at half the price.
The video below demonstrates quite nicely how the non-essentials can also get powered.

thank you. but the CT function is missing. 

 

what i would like:

either a 24v inverter with CT. that way i can keep the essentials connected to the inverter, and excess PV feed back to the non essential side, that way making most of the panels. and night time we only have essentials running during load shedding anyway. 

 

OR

 

dual output inverter, essentials one side. non essentials other side. also making most of the panels, but then the inverter needs to be sized properly so everything can be connected to the inverter, and they normally not available in 24v.

 

battery storage is rather expensive, and since 2.54kwh is sufficient to carry the essentials for a 4 hour load shedding. i dont see the need to increase capacity. not trying to get off the grid, but instead use all PV available during the day without oversizing the system. 

 

other alternative is to get a grid tie solar inverter, the issue is, the drop off once the grid disappears.....

or buy a 5kw inverter that can run without battery, and let that supply the non essential inverter and from there the DB. once the country falls appart completely splash out on a 48v battery. (i have a 24v 3kw Mecer system already, PV capability is just very low, only 600w)
