Any ACTUAL experience with EASun?

[Miles B]

I have read a handful of comments where people ask if EASun and MPP are the same product internally. There have been a few replies stating that "the internal components are lower quality". I am very skeptical. Does anybody have any actual knowledge that EASun is not the same product? I am aware that MPP is possibly a Taiwanese company, and EASun is Chinese. My understanding is that Voltronic do ALL of the manufacturing.

The reason I ask is that there is one MPP importer in Australia, but the comments around their after sales support seem like buying from them is not worth the 30% premium in price vs buying EASun, or possibly importing MPP myself, if I can find a reliable overseas seller.

Does anyone have any concrete evidence of these "lower quality components" or any other experience with EASun?

Alternatively, is there a decent MPP seller in Asia that will ship?

I think EAsun sells inverters made by Voltronic / SRNE / Sumry. I'm not convinced that the internal components would be of inferior quality.

I recently installed the EASun SMW 8k inverter, the equivalent of the MPP PIP-8048MAX.

So far it would appear to be an identical unit based on comparisons to others in the manner it is operating (it has some rather interesting quirks it shares with the 8048MAX) but frankly, without someone doing a full teardown and comparison of the internal components and boards, we will never really know. There may ultimately be firmware differences.

But here's the kicker - there are "genuine" EASun branded units and cloned EASun branded units. I don't even really know which of those mine is.

I wanted to support original developers but at the end of the day MPP Australia were unable to supply the 8048MAX and they kept pushing back the delivery dates. Looking online now it is still listed as out of stock, many many months after they promised they would have them. I was getting all sorts of nonsense stories as to why they were being delayed. It wasn't encouraging. Just tell me the truth.

In my case a bird in the hand was worth two in the bush so I went with an eBay seller of EASun who at the time had stock in an Aussie warehouse.

If you think the level of support from MPP Australia is not worth the premium, don't expect any support from EASun.

I think EAsun/PowLand just resell OEM inverters with their label, they don't manufacture anything.
And what you say is right, do not expect any service from EAsun.

Why make a clone of an EAsun when you can directly clone Voltronic / MPP / SRNE ?

I haven't compared each component of my inverter with its SRNE father, but the cards look alike like two drops of water.

Do you think the Chinese are racking their brains setting up factories to make clones? It's amazing the number of Chinese products sold under different names. I think a lot of the components/boards are shared and they are the OEM product specialists.

This screen is used in a large number of Chinese hybrid inverter produced in different factories.
This screen is just a component produced by factory X and sold to the factories that produce the inverters.

Copying a label and sticking it on the front of an inverter is an easy way to make people think they are buying at least a brand name with some level of recognition rather than an unbranded/unknown name.

Thankyou very much for your post. I was looking at this seller.. think I will probably buy from them.

I think that's who I bought my unit from - they had a stock of some items locally but the business they use to fulfil local orders is pretty crap. It took a bit of to and fro on why my delivery was late but eventually my unit arrived in good order.

If that's the inverter you are after it doesn't look like they are in stock locally, so you'll have to deal with importing and all the headaches which goes with that.

I guess what you're interested in is the price ?
Otherwise you can probably buy better inverters.

Here is a YouTube link where this model built by Voltronic is also sold under the name of WKS Evo Circle has been tested by a specialist in this field. (in French but you can activate the English subtitles).

Here is what Guillaume Piton says about it:

• Easy connection with Pylontech batteries
• No-load consumption between 60W and 80W
• Do not put more than 4800W panels (120A MPPT board)
• Even if it is displayed as 5.6kW it is better not to exceed 4kW to preserve it
• Fairly good AC signal
• SCC MPPT not top at low light
• Given its high internal consumption, you have to check the battery requirement and maybe for the same price you can buy a more expensive inverter that consumes less and less battery

Would fit this model : https://voltronicpower.com/en-US/Product/Detail/Axpert-MKS-4-3.6KVA-5.6KVA

Why would you not put more than 4800W of panels on it? He says "for obvious reasons". Uh, no, there are no obvious reasons. You can happily put a shitload more panels on any MPPT as long as you don't exceed Vocmax. This is common practice to get max output across more hours. Exceeding Iscmax is even not really a problem except possibly to the input contactors, and only if you want them to disconnect in the middle of the day without shutting the MPPT down first. The MPPT is free to just use what it can. He just discusses his particular use of 400W panels. Yeah, there are other panels out there buddy.

Not having a lot of confidence in this fella.

Where does he come up with 4kW? Just "don't run it too hard, I'm guessing.. uh.... 4?"

What "better" inverters are out there? I can buy two of these and have redundancy, capacity for my 12kW array, plenty of charging capacity, and they have a full set of features. I don't see the downside. And I don't see the reason to pay triple.

I don't know, watch the video at 5 min 15 sec.

 

[Miles B]

Yeah I did... he gives no reasons and I have no respect for his opinions.

I advise you to inform yourself well about this inverter before buying it. I just discovered yesterday that my EAsun SMX II 5.6kW also has a high idle consumption and on an isolated site it will be a problem in winter.

Consumption from battery :

Victron will be more expensive but idle consumption is much lower.

Consumption of Victron Phoenix inverter :

24V 3000VA : 20W
48V 800VA : 9,5W
48V 1200VA : 10W
48V 3000VA : 25W
48V 5000VA : 35W

Victron Multi RS Solar 48V 6000VA (hybrid inverter) : 20W ?

 

[Sleeper85]

This is my first experience with a hybrid inverter and I wanted to test EAsun knowingly.

It was only after receiving it that I discovered it was a SRNE.

It was obviously the low price of 543€ that attracted me.

It's been tested at my place for 1 month but not really in production yet.

I voluntarily took a 5600VA while knowing that I was not going to draw more than 4000W occasionally.

I won't use more than 4150W of PV. Currently 3320W.

For the moment it does the job, if afterwards I'm not happy with it I could replace it with better and keep it as a Backup.

I plan to buy a Victron 800VA or 1200VA inverter to save energy in winter / at night. It is necessary not to operate with a single inverter on an isolated site.

For the moment, 3 negative points:
High idle consumption 50W
Unstable MPPT SCC at low light, minimum 150W from PV for stable charging
Very low power factor on low load AC input. (Ex: 400VA / 48W)

Sorry if I put you in doubt, you will buy knowingly.

 

[Sleeper85]

I too was warned by a friend who owns 3 EAsun SMG II 5.6kW.

Here's what my friend said:

All I can say is that when the EAsun work, they work well but they are still a bit short-lived.
Out of 11 in production at home and around me, 6 have already broken down once and often in the first 3 months.
You must handle the PV input with care and never while they are ON, protect yourself well from a short circuit on the battery input and install them in a dry place.

I bought anyway ?

SBU idle or low load: 50W ( it's 1.2kW per day)

48V 5000VA : 35W

Victron Multi RS Solar 48V 6000VA (hybrid inverter) : 20W ?

For the price difference, 15W is nothing. 0.36kWh per day.

Victron also has no charge controller in the unit. And their charge controllers are low voltage which are basically worthless today.

 

[Miles B]

It was only after receiving it that I discovered it was a SRNE.

Right, well that's not even the unit this thread is about, nor the one you linked to in the video, nor is it built by the same manufacturer. I am talking about Voltronic units. Specifically ISolar-SM-IV-5.6KW.

So... read the manual?

I'm talking about my experience with EAsun, that's the title of the topic.

 

[Sleeper85]

For the price difference, 15W is nothing. 0.36kWh per day.

If we compare it to a Victron Multi RS Solar (AIO) given for a consumption of 20W it makes a difference of 40W so almost 1kWh per day more.

So you have to buy more batteries to get the same. And given the price of batteries, maybe a more expensive inverter is worth it.

Why would you not put more than 4800W of panels on it? He says "for obvious reasons". Uh, no, there are no obvious reasons. You can happily put a shitload more panels on any MPPT as long as you don't exceed Vocmax.

I would advise limiting PV on any MPPT to no more than is listed the MPPT's specifications.
