Sunsynk customer service

[Isetech]

Maybe this will help you make a decision:

I can supply you the equipment, the prices must be good because I supply other contractors and I have family I need visit where you live .

I have done a fair amount of research and completed a number of installations, dont need the manual anymore and you have my direct number.

The tech support has improved to a point that I feel comfortable, giving them 9/10, why only 9/10, there is still room for improvement, which I am sure Keith will get sorted out.

The only downside to Sunsynk at the moment is brand specific training, I have had to learn the hard way, which I like because I get to learn more than the people who dont experience any challenges. They need to up their game if they want to stay ahead of the rest.

Some might say Deye is a better product, if you havent figured that they come out of the same factory, same prices and the same tech support, I am on all the support groups, if you dont offer proper training you gonna end up with 10 000 messages on groups asking the same question over and over, lots of warranty claims. Some might say you can watch all the videos, I dare to to try stay awake longer than 2 videos. I have watched all the videos (every single one) and read all the manuals more than once and still asking questions.

Some might say there is another product which is the Rolls Royce of inverters, I am not convinced.

One important piece of advice, which every brand you select, dont mix products. I have customers who saved a few pennies buying other brands of batteries and mixed with Sunsynk, DONT. If you do decide to go Sunsynk make sure you buy a Sunsynk battery. We only install Sunsynk IP 65 5.1 kwh batteries, rack and stack them. Some will say the 5.1 is a C0.5 rated battery and the Sunsynk 5.3 kwh is a C1 battery, burnt once, twice shy.

If the design is correct, installation is done properly, parameters set correctly, circuits split as required to prevent overloading, you going to wonder why people complain about load shedding and save a few bucks. We hardly ever install systems for load shedding anymore, now it is more about saving money.

Will I be doing myself a mischief buying one ?

Must apologise to Isetech for hijacking his thread but seeing that feeding back into "my" grid was explained, there's still something that I'm grappling with to understand.

Ok, so my db is split into essential and non essential. Inverter ( real hybrid ) feeds the essentials. Now any eccess power generated by the panels can be fed to the non essentials without loading the inverter.

My question is. How does the excess power from the panels (dc) get converted to 230vac and feed the non essentials without going through or loading the inverter ?

The " excess power " from solar is fed back on the same line/terminals that mains power is fed into the inverter

On the grid side it has to have grid to follow , it cannot create grid and will only fed in and supplement " eskom power"

For us sparky' s it is a difficult concept to understand but it does work

Thank you, brother. So this can only happen when there is Eskom grid available.

[Isetech]

Go to system mode-grid trickle feed.

I have a bunch of Sunsynk plants on my profile that I mange, if any of the regulars on this platform need help with Sunsynk or want to me to log into your plant, I sort of have an idea what how to setup the Sunsynk units. I dont do parallel units and dont plan on doing any.

Was not aware that one could program the minimum power on the Sunsync.

You have my number, if you need advise or a good price for Solar panels, inverters or batteries, I dont forget people who do nice things for others, my new hydraulic crimper works a lot more than I even expected, perfect for all the battery terminals we make up.

I have a supplier in your area. they just dont do solar panels deliveries unless you buy a pallet. We just hire a trailer and collect.

By the way I got the new price list this morning, there has been a another decent price decrease again.

Something to note, I am trying to get the bank to give me a few hundred thousand so that I can buy my system and install it before the elections. they say we are only going to go to stage 2 after the elections, and load shedding was to be sorted out by 2009.

People say that the service delivery is due to the elections, I am wonder if the it not more about trying to get as many tenders started before the elections, so that payments can be made ASAP, even if it is just partial payments for projects.

I have never seen so much grass cutting, road repairs, freeway bush cutting, lines being painted etc in the past 16 years that I have lived in this area

It has become such a pleasure dealing with Sunsynk tech support.

Today I needed help with something, logged into Sunsynk.net - go to application centre - customer support - start a live chat and bingo within a couple seconds you get a response.

If they cant help they redirect to the people in know.

They get 5 stars for the awesome service.

@ Isetech. Not ready to buy yet. Still checking prices. For me the main motivating factor is price. It does seem as far as solar is concerned, the longer one waits, the cheaper they become.

I only work with cash, so price is important. Today I got a price of R2700 inc vat for 545W panels. I remember not so long ago they were 4K a piece, so it seems that the longer one can hang in there and survive without an inverter, the cheaper it's going to be eventually when the decision is made to buy.

Pressure was put onto a couple of my friends by their wives to install systems so they went out, made loans and obliged. Fortunately I'm married to a boeremeisie who completed all her studies with the light from candles and parrafin lamps. She knows how to survive without having electricity and has passed those skills over to me. Yep, they are skills. The first time her parents had an electrified house was after we got married and I decided to surprise them and arrived on the farm with everything needed to electrify the house. 3 days later they had power and her father made it quite clear that he was not impressed. It cost him an absolute fortune to go out and stock up on electrical appliances.

I feel guilty to this day. I don't think he ever forgave me.

Anyway, sorry for the essay. Just wanted you to know that I've got the cash, but ain't in a hurry at the moment.

BTW, I'm still battling to understand how the inverter can take the excess dc from the panels and add it to the AC input without it first being inverted to AC. I'm digging and won't stop until I understand how it works.

Chow for now.

Check this How To Convert DC to AC | Direct current Inverting | 3D Animation, you can fast forward to approximately 4 minutes where it really starts getting interesting, if you already understand AC and DC. Unfortunately there may be some advertising at the start.

Thank you, brother. So this can only happen when there is Eskom grid available.

Yes it only happens on grid present

It is basically being converted from DC to AC and then " fed" to the grid - It is not being " drawn" from the inverter

On the essential side the inverter has to supply the load and that load will determine the current and if the current is over the capabilities of the inverter it will trip

On the grid tie size - the inverter will only feed back excess power , it is not really worried about the load - the load will demand from the grid

[Derlyn]

Ok brother. Now I eventually understand. I'm a slow learner, but once I understand it, I very seldom forget.

What I was grappling with is the fact that the inverter does not take that excess into account as far as it's overload limit is concerned. I found that difficult to understand as the inverter is still inverting that excess dc before sending it to the grid.

I cannot think of anything more frustrating than dealing with a technical support centre that has unskilled people in that field, and every time you ask a question they put you on hold while they ask someone else for the answer.

This is why I make sure I figure out who the people are who know their stuff.

I opened a chat with Sunsynk tech the day before yesterday, advised the person of the issue and they requested the SN and gateway key, a couple minutes later the problem on the one site was resolved, I was then informed that the others would take a while to update.

So today I opened the app on the phone and imagine that, "NO DATA" , I opened another chat and asked the same question, shared the SN and gateway key, this time I was told that they cannot resolve that type of issue and I would have to contact Susnynk.org

[Isetech]

What I have learnt about IP 65 5.1 kwh Sunsynk batteries:

1/ All the battery data is visible right down to cell level, state of the battery, number of cycles etc.

2/ You can get firmware updates done online, the same people who do the inverter firmware upgrades, can also upgrade the battery firmware on line.

3/ IF you go to the sunsynk app - equipment - battery you can see every detail about your battery, including the firmware version and everything else you need to know about the battery.

4/ If the the battery info is not displayed on the app under equipment, then you need to log into Sunsynk.net go to application centre, then customer support, open a chat and request they authorize to link the batteries to the plant. It should be done within a couple of minutes, if not you are in for a bit of head banging.

5/ I would suggest you get the installer to make sure the data is visible before they leave site, it should only take a couple of minutes if it doesn't load automatically.
