Sunsynk MAX 16 KW !

solardad · Feb 16, 2022

Came across this announcement from Sunsunk.

There version of DEYE that looks to be killer.

That's an awesome monster.

I'm interested to know what the rated PV voltage is. Hopefully it is the same as the 3phase models which have a rating of 800V (MPPT range of 200-650V)

Otherwise if it just has 3 MPPTs rated at 450V, then it would be a struggle getting anywhere near 16kWp of solar without using parallel strings.

I just stumbled across the datasheet for this. Sadly Vocmax is only 450V. It has 3 MPPTs that can each take two parallel strings.

Also, note Deye has announced the same inverter, which will no doubt have the exact same specs at a cheaper price.

Price in SA is 60,000Rand which is US$4027, or about 3 times the price of the 5kW version.

I'll be sticking to 3 of the 5kW version for the 6 separate MPPTs and a bit of redundancy.

That is a Deya inverter. SunSink , just puts their name on it. But, they don't try to rape or bs their customers.

What is this raping and BSing of customers that you speak of? I'd be keen to hear more.

I have already formed my opinion of Sunsynk and the CEO Keith based on him ignoring my questions on the Sunsynk forums and his youtube videos.

And I have so far had great assistance from the Deye team.

I believe he is referring to the SolArk, which is rebranded Deye sold at 3x the price. In addition SolArks are marketed as being all American Hoorah USA veteran built etc. all of that is tough to accept when you know that it’s a Chinese designed and manufactured product.

Yup

Deye, is a great product.
SunSink, rebranded for a fair price.
Sol-ark, would steal from little old ladies, and not feel bad about it.

I wish it was that simple ??

Love all your videos. I got some questions for ya if you could spare the time.
What was your role regarding the GTIL2s?

So maybe you can put another discussion to rest. There’s been lengthy discussions about this..
Is the SolArk just a Deye inverter that they slightly changed and slapped there name on it for a much higher price?
Which came out first,, the SolArk or Deye hybrid?
Same question for SunSink hybrid but at its fair price instead of much higher?

Keith Gough said:
It’s mppt string v is much higher

Thanks for your replies Keith.

Can you advise what the max string voltage is? I was basing my information off this datasheet which specified 450Vocmax.

Hi this is Keith, I receive upto 1000 emails what’s app we chat, feedbacks a day please accept my apologies if I can’t physically reply to everyone

Not sure what you mean cheaper price, as sister companies we price match you can choose which operating system and Apps you like

True, my comment about the Deye being at a cheaper price is probably unjustified. I was mainly referring to what I expected the Sunsynk would cost me to import from somewhere (Australia? South Africa? UK?...) (no local supplier here in New Zealand) vs what it would cost be to import Deye inverters from China.

I'm sure if I was living in one of those countries with a Sunsynk and Deye importer, the prices would be comparable.

I understand, I was wanting to determine if the Sunsynk software supports an external meter connected via RS485 like the Deye does.

cods4 · May 31, 2022

A headsup to the Australians and New Zealanders. Some of the Sunsynk inverters are now approved and listed by the CEC.

I have a sunsynk 8kw inverter. Sunsynk's firmware compared to Deye's Firmware is way better.
Better GUI, better mobile application for remote monitoring and making remote adjustments to the inverter.
Simply hate the deye flow chart.

Wet1 · Aug 27, 2022

Keith, are you selling your products in the US? I asked on many of your videos, and also inquired on your site, I never once got a response. I took that to be "no" so I went ahead and finally purchased a SA. I'd still like to know the answer though since Deye wont sell here.

You will find that he can't because of sol-arks exclusivity agreement with Deye.

Deye won't sell split phase inverters to anyone other than solark

SunSink doesn't sell a split-phase inverter, as far as I know.
I have plans for a couple Deye in the future. But not interested in split-phase, anyway.

You might be able to get a single phase inverter from deye directly then.

That's the plan, but will have to purchase through a friend in the UK.

I’d like to say everybody who uses Sunsynk thank you very much for your support and we will keep striving to make the best operating system and best backend server/apps in the world

Unfortunately due to contractual reasons we’re not allowed to sell in United States, You’re probably a aware the Inverter has three versions of the operating system.
Sunsynk
Deye
Sol ark

Sunsynk focus mainly on Western Europe, Australia, Hong Kong Southern and central Africa

Thank you for the clarification Keith.

themizz · Aug 29, 2022

@Keith Gough, I saw you mention on a video it is possible to flash a Sunsynk with Deye firmware and it would still function with some limited features......is is possible to do the opposite?, Flash a Deye with your firmware and still have it be functional?

I'm specifically asking about a split phase Deye.

Thanks!

The neat ”trick” the sunsynk hybrid inverters have of matching their phase to the mains then using tightly controlled output voltage to supply just the power the house needs without going high enough in voltage to export to grid - I suppose this is shared by the Deye and Sol-Ark inverters being mentioned in this thread as closely related (same?) products?

Are there any other hybrid inverter manufacturers using this approach? I would be interested in a smaller version which supports lower PV string voltages and 12V (4S) LiFePO4 battery, but this does not seem to exist in the Sunsynk / Deye range. So I‘m wondering if this smart power distribution control technology used by the SunSynks / Deyes etc might also exist on inverters from other manufacturers which are designed for smaller systems such as mine.

Wet1 · Aug 29, 2022

The smaller (and cheaper) 1000W and 2000W SUN limiting GT inverters found on ebay can do it as well, but you'd need a seperate charge controller. Again, these are not hybrids though.
