I’ve got one of these, 2x 5.32 kWh batteries and 6400 watts of solar panels, it’s absolutely fantastic, it’s been making 15-16 kw per day and this is July 2024. Over the moon with it. Power shaving is a good feature on the inverter too. Very happy with my purchase.
This SunSynk 3.6 kilowatt hybrid inverter is a great example of the future of home energy management systems. It's a Swiss Army Knife of inverters and eFIXX has done a great job of delving into this topic in depth. Thanks, @life-is-here
Long time viewer, first time commenter. Love this, please make more of this prosumer content. I am on the final stage of my setup - 3kW of panels and 10kWh li-ion storage with a LuxPower hybrid inverter which seems similar to your SunSynk - and that is adding a separate downstairs ring circuit fed from EPS/UPS supply. I buy 10kWh of energy between 12:30am and 4:30am for 15p per unit, as well as running the washer & dryer and charging the car at that time. Very soon I’ll have the lights, boiler and downstairs circuit islanded, to overcome the flaky rural grid around here.
Great video and yes the DC isolators can be omitted if the inverter isolator complies to EN60947-3, the appropriate control measures are in place, trained and competent persons are used to carry out the work. Otherwise, why would you have an isolator before an isolator 🤷♂️
Depending on the inverter disconnect (what we call isolator switches on this side of the pond) means that you would have live PV wires in the inverter unless you shut off any disconnects at the array, as we *never* use MC4 connectors at the inverter. Everything is in conduit or a raceway of some sort.
But you would not have a DC isolator and an AC isolator in series. No cable in the installation is going to be carrying DC and AC at the same time, or even at different times.
I think the battery connection at the top felt the most natural and most of us would have fitted it that way. Knowing what we know now I’d of fabricated a cover to complete the IP rating up the way 💪👍
Is there a maximum length for the CT connection ? My inverter and solar panels will be at the garage 50m away from the incoming meter tails. The garage does have a separate consumer unit but will not be useful for CT connection. Will the signal and wiring manage the 50m distance?
yes but nothing for the end user. I keep trying to find answers to really basic questions for the end user. they don't answer comments or check their own forum. this video is a good overview. love the inverter but it's made for engineers, and even then the installers don't learn the configuration post install.
Hi great vid! My Sunsynk system (same as this but with 2 batteries) has the batteries mounted upside down in the loft, is this a problem or should I be going back to my installer? Thanks!
App goes down a lot and it outputs a high pitch noise at 15kHz. Old firmware capped PV to 3.8kW but has now been fixed. Otherwise not bad. App issue can be solved by installing a pi with solar assistant on it. Noise issue can be fixed by being old.
I’d say DC isolators not needed if the inverter didn’t have a built in isolator that follows the correct guidelines would you fit 2 DC isolators “just in case” if you look at the system I just fitted which is the new slimline attractive models it would be ruined by an industrial looking isolator next to it
Which director does the manual say the battery should be on that manual? Even thou it’s a LFP battery you don’t want the electrolyte not to cover the busbars correctly most manufacturers stress a set direction for use.
The battery can go in any direction, it’s the wiring regs which stipulate the IP4X requirements. Originally they were designed to mount in 19 inch racks.
This sort of setup is best if you have a ground floor utility room (such as a small extension to your garage) where you can hide away all the bits and bobs but allow easy and safe access for maintenance as putting them in your loft really annoys the Squirrels hiding away there
Guys looking for advice , I’ve just nearly bought one of these with 2 x5.2 kw batteries all Sunsynk for £7500 installed . I was quoted that these are the Rolls Royce but when I search on line there seemed to be big abroad but newish to the Uk and I was worried about support. I ended up not committing, have I made a mistake or is there a better option . I already have a 4k solar panels and string inverter but have been told I need to replace inverter. Is the Sunsynk a good buy? Or should I buy an alteration appreciate your advice
Early in the video you refer to the incoming DC as “high voltage” and the shortly afterwards that it is 450V (approx). You may want to clear that statement up. Otherwise I now find myself wanting a brand new setup!
Qtn: I always thought a hybrid inverters can work independently without a battery pack.. is this true? I.e, my house can be powered by solar during the day and switch back to grid in the night or when there's no sun.. I need to make my choices right here on whether I can cut costs by eliminating the batteries. Thank u
Excellent video Gordon , very interesting. Unlike EV , But I can’t help thinking why thaff around with all that stuff why not just do what a lot of Americans do and go completely off grid? . Great video as always 👍
@@Dog-whisperer7494 No there is a house near me which didn't want electricity when they electrified the area in 1956, and today it would cost over £25,000 for the 11kv network to be extended - It's staying off grid.
I just had Sunsynk 5kw plus 2 x 5.32 batteries with 6.4kw panels on 2 strings. It was fitted with DC isolators and 2 AC isolators either side of the export meter (the guy fitting it didn't see the point of 2 or the export meter). But they did not fit battery isolators or fuses as the batteries apparently have something similar built in. True?
I asked the installers and they contacted SS who said it wasn't necessary to be compliant in the UK (South Africa requires them). The batteries BMS has built in protection i was told on the Facebook forum

I've used Enphase before on a mini DIY project, they are great micro inverters and as far as I can tell seem to be the only ones that are officially certified I think. The output wattage is limited. I have some cheapish Chinese micro inverters which work well with high output (linked to Shelley devices). Reading this week tho, I think none of these Chinese inverters are certified and you will not be able to get sign off by your local DNO, which in turn means you cant get paid for your export. I'm not 100% sure as I'm still learning. I'm now more leaning towards the victron Multiplus 2 low frequency inverters. They are more pricey but rock solid from my research. Enphase do offer a battery solution now also, but I don't think its been launched in the UK yet. The optional control unit from Enphase for the microinverters is about £350. From what I've been reading this week, if you want to feedback energy to the grid you then have to purchase this optional unit to keep DNO happy to get paid for the export.
@@stevengajek you thinking of putting cheap Chinese micro inverters on your roof under the panels ? Hope you got your own scaffolding and roofing kit. If its on the roof you don’t want to go there for 20 years. Personally that’s the reason I wouldn’t fit them. There are some advantages if you have shading issues
If like me you don't want the app and transponder the generation meter is an essential part of the set up and a n independent check of overall performance so do not consider it's ommision.
Please tel me you have a fuse protecting the cable from the solar panel to the inside and by that i mean a fuse located at the panel.A good demo will be to show people what happens when you short to pv cables and seperate them ever so slightly with no fuse. ;-)
Still lot of DC voltage after the inverter... If the positive cut in the solar string will it arc on the cement, galvanized iron(coated vs bare metal) and other roof materials???
Most the inverters we use have SPD’s built in for both DC and AC. They also have an alarm that registers the SPD activation. However their manuals also recommend fitting tour own external SPD’s. I imagine this is because it extends inverter lifespan and its easier to change your own SPD than call out an engineer for the inverter.

Your videos are so much better than the actual SUNSYNK ones, which mostly seem to be a guy talking but not showing you things.
Please use the MC4 wrench to tighten those connectors, they do not look tight enough.

You can use these as regular solar inverters and add batteries later if required.

sunynk need to look at the mounting arrangements of the 3.6kw ecco, it always looks like its falling off. Not seen one yet that is vertical.
if you have 2x sunsynk 5kw batteries in parallel what is the max amps you can set the inverter to in order to maximise charging rate?
5kWh, not 5kW.
Battery capacity is measured in kWh, inverter power handling is measured in kW.
but you could still answer Catfaces question @@deang5622
2 x 5kWh fed at 5kW is two hours storage is that a rate of C = 2?
The Sunsync 5kW inverter can charge/discharge a max of 125A, so even for 2x100Ah batteries you can only draw 125A
So in the settings I can set it to 125a and that will max out the settings?@@padraicberry8856
Looks like the install in my loft. 😀

I just had Sunsynk 5kw plus 2 x 5.32 batteries with 6.4kw panels on 2 strings.

But they did not fit battery isolators or fuses as the batteries apparently have something similar built in. True?
All the manuals suggest that battery isolators and fuses / circuit protection should be fitted.
I asked the installers and they contacted SS who said it wasn't necessary to be compliant in the UK (South Africa requires them). The batteries BMS has built in protection i was told on the Facebook forum
Wouldn't do any harm to fit them.
Hey how are you Sunsynk Batteries? Would you recommend them
@@silkstar20 no issues so far
What is the difference between a 3.6kw Sunsynk Hybrid inverter and a 3.6kw Sunsynk ECCO Hybrid inverter please ?
Both isolators are classified 60947-3 which means both of them can be used on AC or DC, are the manufacturers scamming us with the DC-only Isolators?
Here’s a sneak peek 🫣 there is a difference!
ruclips.net/video/YxHCDs03UEg/видео.html
Is a video on the battery performance?
We have a 5kw sunsynk with 10 450w solar panels and we still buy the same amount of electricity every month it's like it's not even there

We haven’t looked at micro inverters yet. Last time we checked Enphase didn’t have a battery solution.
