In SA, due to daily loadshedding my deye (sunsynk) solar setup works like a dream!... The hybrid inverter works great with no grid supply, so my question is, would the hybrid inverter still work with a national complete blackout?
*Very informative! Thank you.* The choice of a battery is one of the most critical decisions that need to be made when designing a grid backup or enhanced self-consumption solar PV system. The Performance cycle life from a LiFePO4 Daily Use Battery - 5.12kWh is 8000 cycles. I am considering purchasing a Syn Synk 8kw inverter. The weblink below does not reflect the cycle life for the Syn Synk battery. Please could you provide the Cycle life? Is the Cycle life 6000 cycles or 8000 cycles?
I have 1 sunsync 5.12kWh inverter, and 2 x 5k batteries, with 8 x Canadian 545 - and live in South Africa where we usually have good sun. Does the dual battery installation imply that I will have extended use cover time? I've found, through reading multiple articles, that I can expect about 10hrs from 1 battery if it is connected for fridge, TV with some lights connected - aka - not a heavy use through high draw items aka geyser, stove, hairdrier, and so forth. Does having 2 batteries imply I have twice the time cover, or is this too simplistic an approach?? I would love guidance.
Great video, thank you! If I have two 5 kWh batteries I’m assuming they are connected to the inverter in a parallel manner. Does this mean that in total 2500 W can be supplied on the 0.5 C batteries? Also can these batteries be charged with excess solar when the grid is down? Thanks
@@sunsynk thank you. How? For now us Deye and Sunsynk installers have to ask Pooja😂 she’s helpful but it would be cool if there was a button in the app or something.
Hey! I am from Pakistan and my inverter is a different brand than yours but can someone explain the F18 fault, its the same as in your Inverters that is: AC overload Fault. It happens sometimes when the power goes out which happens very often here and the inverter is on heavy load like 4KW (my inverter is Inverex 5KW). But today in the morning I got the same error but there was no load on it and I believe the power didnt go out too. I check it online through the app and it was running on about 700W. I have a hybrid On-Grid system. So If anyone was able to fix this I'd really appreciate any help. Thanks!
Why is there a voltage ( 48v - 90v) between neutral and earth on AC outgoing side of the inverter. This now causes that voltage in the main board ( 48v-90v between neutral and earth ) This is not good for your appliances
It would be even better if you guys can fix the obvious grammar issues on the Sunsynk app. It's really difficult to explain how you can export excess production when "zero-export" and "solar sell" is ticked at the same time. Time to get rid of the chinglish and work on getting the app to show real time data.
It’s something that we are looking at now, This is not a backward translation more understanding, We change the wording several times. We will review again but generally we don’t have any issues in the understanding Thank you for your comments
So where is the cheap overnight energy? Octopus don't offer any for solar storage, only for EV owners and specific battery only systems. So when we are all hooked on EV's what a shock when the subsidy is removed as per solar. Is the dirt cheap solar pumped back to the grid subsidizing the EV's. You say that the batteries are suitable for floor mounting but surely that only applies but surely that only applies to non inflatable ones such as a concrete garage floor.? In response to one coment, while the business transaction and installation were first class the follow up was appalling and what for them should have been simple solutions became protracted and unresolved. After one month I discovered the UA-cam videos and decided to look at the inverter only to find out that everything was at factory default settings. They sent an incompetent out to adjust the inverter to cover my overnight usage and instead of saving me 30p ended up costing me £1+ more per day. Note, solar is a classic example of the old adage 'look after the pennies and the pounds will look after themselves'. I am now close to full cost savings except where I use the kettle or micro wave but I'm happy to live with that. A big bonus is that I can now exclude the installer and SunSync from changing any settings without my knowledge so I am in total charge as far as I know. My biggest grumble with SunSync is that the do not give simple and precise examples to guide the owner so that we we are not making silly mistakes and are totally installer focused. Another grumble is that they have not issued a restricted version of the app that permits changes to be made via whyfi as my setup is in the loft and it won't be long before I can 't access it.
Really annoying and distracting jingly music. 15 minutes of that over and over again! Please remove it. The explanation is good and ruined by the music. I had to turn off the sound and read the subtitles.
I want to add to my reply of 2 months ago by saying that that the addition of a battery to solar PV for most domestic customers is a waste of time and has been mis sold to us by the manufactures and the trade. We have been duped and had the technical wool pulled over our eyes. Whilst the costings we are shown would appear to be due to the battery this is not actually true and the effectiveness of the battery is dubious. (1) The comparison should be made between a battery system and a comparable non battery system. My 6 kW panel 3.5 kW Sunsync inverter plus 5.2 kW battery cost 10 grand whilst I estimate that a non-battery system with identical panels would have been 6 grand max a saving of 4 grand. (2) The solar conversion for consumption is identical for both systems. (3) Both systems export excess solar to the grid but when the battery is charging it is not exporting whilst the non-battery system is. Octopus GO export tariff is currently paid at half the price capped rate so the cost saving due to the 5kW battery compared to non-battery is reduced to unit cost X 2.5.(4) Battery linked inverters are more complicated, costlier and probably more liable to troubles than bog standard ones. There are no battery costs, maintenance or replacement costs for non-battery systems. (5) Lithium batteries are a potential incendiary device particularly when they are wi-fi connected and controlled by third parties. As the inverter only need one program for both winter and summer there is absolutely no need for third party intervention. (6) If my battery failed I would not replace it and would run as a non-battery system. (7) In the summer when the days are long, the battery full and the nights short there is the least requirement for the battery. In the winter when the days are short and the dark hours long the battery is mostly empty so is contributing little or nothing to cost savings. My battery is now running mostly empty and I have a charge cycle once a day to protect it from being discharged for days on end. (8) Being a modified inverter the SunSync clips peak load to half the battery capacity so that solar export is lost compared to standard inverters. (9) Since these facts were not drawn to my attention when I was sold the system or when contacted by telephone or online quotes I consider that I and everyone similarly affected have been the target of gross mis-selling and if I had the chance again knowing what I know now I would not have purchased a battery linked system.
Wow interesting opinion You have made many bold statements First of all in the uk for about 3 months a year PV system don’t produce that much power but the rest of year is very different. I guess you like to export power during the day and collect 3 or 4p per kWh and buy it back at night for 35p Per kWh Most simulator software for ROI with or without battery you should study some of the 3rd party platforms Your statement about fire risk on lithium batteries can you please substantiate ? Do you know the main fire risk on a PV system is the panels them selves please google it !
@@sunsynkOpinion, opinion, your opinion! It's only your opinion that what I have said is opinion and I'm sure that it is no surprise that I don't agree with your opinion. I live at the top of a small cul de sac with an east west roof orientation so that the eleven blocks of semis running down the street have north south facing roofs and most have had third party solar panels for the past 20 years and none have ever caught fire not even in this summers blistering heat. On the other hand your Keith Gould warns against trying to charge a Lithium battery as if it was a lead acid battery as damage could occur which could initiate a fire if I remember rightly. Now since my inverter can be accessed by SunSync or my installer via the web who can then take control of the equipment; I am already locked out of the 'basic settings' menu, my inverter is at the mercy of incompetents like Tom who was sent by my installer to set the inverter program to save 28p and ended up costing me around £1.20 instead. Or inded any employee with a grudge against their employer. This has been of concern to me since I got to know this fact as there does not appear to be any way to reduce the risk by changing menu preferences and the intransigent attitude of SunSync and the installer to my plights goes unheeded, an absolute disgrace and something that needs addressing. SunSync and I believe other manufacturers behaviour is comparable to a car manufacturer selling one a high performance car which on delivery runs like an old lumpy banger due to a badly set up engine management system and one then has to buy into the car dealers care and maintenance plan to correct and even then you only get what they choose to give you. One also has the same fire risks with SunSync as I believe that chinese companies must have close ties with the chinese government. So as I see it, in the event of a blow up of hostiliies in the South China sea then the inverters can be remotely tampered with by the chinesse government and no one would be any the wiser until it was too late and some lives would be lost as well as the disruption that would occur. Ukrainethe European Union certainly didn't. Also panel fires are external so easily spotted and the chance of getting out high. Not so with internal battery fires many of which would be in the roof space. As you say very little solar is produce from November through to the end of March. So why am I running my battery as an 'empty bucket' when accessibilitymanner that SunSync and the installer refuse to give. Your videos are next to useless regarding the fine detail and your Keith Gould, whilst I admire his enthusiasm is not the right man for the job. I am not against your products which I am sure have a place in many worth while applications world wide and was pleased to have one until my enlightenment, it's just that battery back up is not justified on a cost saving basis for basic domestic PV in Britain but it's good for the dealers and not the customers hence our exclusion. I am an Octopus customer on their price capped tariff which is currently 33p a unit and on their Octopus GO export trariff of 15p a unit and based on the last 2 years pre smart meter consumption with my previous supplier I consume 7 units a day on average which is £2.31 a day. The best the battery can do is 5x0.8 = 4 units a day which is £1.32 a day. So for 2/3 of the year is 243 days at £1.32 which is £320.76. Now when the battery is charging the non battery system is exporting so 4x0.15 x243 = £145.80 so the battery is only saving £160.38 per year. Does this justify an overspend of £4000 minimum based on my over estimate of the non battery system and conservative estimate of the solar plus battery which I have seen as high as £12500 and I'm sure can be higher still with some installers and dividing the overspend by the saving requires 25 years. It beggers the question. Furthermore considering global warming and rape of the planet why are we wasting a precious resource like Lithium on needless batteries.? I'm 80 next but despite that I'm now a man on a mission against solar + battery even though I know I will fail.
@@sunsynk There are some incoherent bits in my comment due to the unnecessary over complicated grammar / spelling corrector which obliterates blocks of what one puts in of its own volition such as, ........

@@sunsynk WOW. I went to open the SunSync app on my phone and found I needed a password, something I hadn't had to do until now particularly as it had been set by the installer and was not as far as I can remember given to me.

I had for some time wondered what the generation meter was actually displaying as it had an average of 3.8 whilst the app was giving an E kWh value of typically 5.3 so why the 2kWh difference. When I took the total E kWh to date and the total generation meter value, they were virtually identical with an average still around 3.8. So why? Well I suddenly realised that the E kWh value includes charging which is storage and not generation / consumption. It does not become consumption until it is released as backup so it is effectively being double clocked by your app. Better still is why when we are two months into winter is the daily generation average being maintained. Simples. I am charging around 1.5 kWh of electric into the flat battery for an hour before midnight which is then discharged as backup by the inverter to the house load. The inverter does not, cannot differentiate between battery power due to solar or the grid. I hope you find this useful and that in future you will be more co-operative to your final customer, the purchaser and user of your equipment.

Yes. 2 batteries mean you have approximately double the time (for the same load) before both batteries have discharged fully.
Does the inverter have single or dual MPPT? I’m expecting dual as I’ll have east/west strings
Where can we buy the sunsynk? We are from the Netherlands. Who has some in stock?
Great video, thank you!
If I have two 5 kWh batteries I’m assuming they are connected to the inverter in a parallel manner. Does this mean that in total 2500 W can be supplied on the 0.5 C batteries?
Also can these batteries be charged with excess solar when the grid is down? Thanks
No double the power over 5kW inverter limited
@sunsynk are you getting deliveries in the Uk? I was due to get my install last week, but nothing.
Several containers due in next week
Have these containers now arrived?
We’ve recently purchased these and we were told we can use the stores energy at night instead of off the grid but this doesn’t seem to be the case??
It is the case if you have the Sunsynk phone App. And I set my system to charge of the grid at off-peak times every night in winter.
Hi,
When will we be allowed to update the inverter firmware ourselves?
Can now
Will look at it

Hi great Channel. For the 3 phase 12kW hybrid inverter, do you get 12kW per phase that is total of 36kW?
It gives out 4kw each phase making it total of 12kw

Technically you can, it's just called Solark. I believe that the software is slightly different but the features are pretty much the same!
