All things Sunsynk (Deye, Inge, etc...)

Luxpower are axpert based as well - well the cheaper one is. Axpert is a catch all for inverters with similar internals - i think its easier to white label axperts than others, so your Mecer, Kodak etc all fall in the generic axpert bucket

are these more for lower usage and time periods ?

cos im seeing a mecer inverter with 2 litihum batteries is around R30k

cos right now im not sure what i want and whats my budget

I dont think thats true. I think its its own design, just competes against the axperts.

Best is to do it the other way round figure out what you want and then look for recommendation on hardware.

The mecer inverters aka axpert aka voltronic are generally built as UPS's by design so work better as such.

But there are so many variations of the axpert and other options that it will be difficult for anyone to advise without knowing what your setup and requirements are.

Questions you need to ask yourself as example:

Do I want loadshedding protection or more?
Do I want to go off grid and to what level?

What do I want on the inverter? (Some lights, internet and a few plugs or everything including geyser)

What kind of warantee?

Do I want solar panels?

Etc

I dont think thats true. I think its its own design, just competes against the axperts.

I could be wrong, just that the interface on the inverter itself is very similar to the Axperts, hence my assertion. But I could be wrong indeed, happy to be corrected

This is a good approach. The other good thing is that the systems are herbal modular so you can add on to it in future

Voltronic is the manufacturer they build all sorts of inverters that are rebranded and reconfigured and sold by different companies some with their own firmware or just the generic "axpert" one.

I cant find any proof of what im saying. But the specs dont match up to other axperts ive seen. Also this comparison from solar europe lists them seperately:

 

[RonSwanson]

what you mean about separating neutrals? Between non essentials and essentials I assume.

Correct. Don't just move the live, you have to use a neutral from busbar on the non-essentials side as well. If you use the essentials neutral with a live from non-essentials it will trip. Might sound silly but many have made that rookie mistake.

he geyser has been super efficient up to now - it switches off at 5pm and is piping hot at 8am the next day... We tend to shower in the mornings. Granted that's summer. Mid term I'm adding another 12 x 450w panels (24 total) and have 11kw on the inverter side available to me, so the geyser will then just sit on a timer on the inverter... or we will simply have a switch to switch between essentials and non-essentials for the geyser.

Yep, but non-essentials availability is subject to Eskom working. If you are OK with that then it's probably alright. Non-essentials isn't great when there is stage 6-8 load shedding..

Can you elaborate on the Aux

All Sunsynk Hybrids have an Aux / Gen port. Download the latest manual from Sunsynk.org, lots of valuable info there.

Quick question... So I have two 5kw machines to be set up in parallel. I'd like to use solar assistant... Can anyone vouch for it working with a parallel setup? I'll be connecting the two using the comms cable for paralelling so assume I'll have to do Solar assistant via DB9. Do both machines need to connect to the Pi? I would assume so. Ta!

*Edit* got my answer: https://solar-assistant.io/shop/products/sunsynk_rs485

Their prices for cables really are a ripoff.

What is interesting is in their example of the Axpert inverters in parallel they say you can read both inverters with one cable. Not sure why the Sunsynk is different here.

thats what i want some pro to come out see what i have and advise

cos i want to still know if i will be saving eskom usage and spending less

so whatever i save i can put back into the solar investment

i have a house with a seperate entrance and a pool . no aircons as yet but in future will be adding on

so need to know whats possible and what i should budget for

 

[I.am.Sam]

unless i start a thread and ask

 

[xrapidx]

There's a plug near by - I'll power off that - then - thanks to my camera setup - I have a network port in the garage, so install should be quick.

Looks like I'm in for 2x cables and 1x software. Next months beer money gone.

Great - now I can't find my spare Pi3 that's been lying around the office for years. Even more beer money to spend.

 

[RonSwanson]

So I have two 5.5kw sunsynks on this firmware:
The older one:
COMM: E428
MCU: 3382-0513

The new one is:
COMM: E428
MCU: 3382-1515

Question - which would you set up as the slave and which the master?

Neither. Request that both are updated to the latest version, and keep them in sync. You can expect nothing but issues if you parallel two inverters with different firmware levels.

 

[RonSwanson]

How many times do you think I need to get them on the same version?

I would think that once is enough. And then when you upgrade one, upgrade the other too.

How sure are you that the MCU slave version doesn't relate to the hardware?

Not sure what you are asking there. The software isn't that well documented for assumptions to be made as to what is applicable and what isn't. So just follow the sage advice of Sunsynk, and Keith Gough, and keep them in sync.

 

[RonSwanson]

I got the new one and decided we'll go with that firmware on both. Requested an upgrade and received it, but instead of doing the version I requested, they upgraded to something newer. I then requested an upgrade of the old one and that one got something newer on the MCU version, so I requested an upgrade via an installer on the SA group and got to where I am now. I've just sent another request via the website. Let's see if hey can do this.

If you are not an installer, then your installer should be managing this.
If you are an installer, then you should be on one of the Whatsapp support groups organised by your upstream supplier, it becomes a little easier to co-ordinate this.

I can't follow advice when they can't either provide upgrade files or do the upgrade for me. My R30k investment has been doing squat for going on two weeks. I'm getting fed up with Sunsynk to be honest. Deye seems to have better support these days.

Then get a Deye then if you think that it is so much better. Here's a tip though, the exact same people in India do support for both Deye and Sunsynk. It's at the higher levels of support that they start to differ.

 

[RonSwanson]

Are installers magically able to communicate something different? The last request was done by an installer.

Legitimate installers who have acquired their inverters from a legitimate Sunsynk partner would know what support channels are available and how they work.

Lol. This isnt rocket science. What is there to co-ordinate? The online form asks the version you're on and the version you want.

Yet either you or your installer seem to think that this is the only channel available for upgrades.

I certainly don't have that kind of time on my hands to manage the process of replacing two units.

Cool, then leave it to a competent installer to do.

For some reason my installer can get Deye updates on demand... I.e. he initiates them. He can't with Sunsynk. He's been trying to sell me Deye units to replace.

Then maybe he needs to try to find out exactly what Sunsynk resources are available to him as an installer, both from Sunsynk as well as his channel partner that supplied the inverter.

 

[RonSwanson]

It's a firmware update.
A 12 year old can do it with a bit of guidance.

A glance at the Sunsynk forum says all you need to know about their support. They really should just shut the forum down.

Cool, you should be sorted then, but here you are.

 

[RonSwanson]

Because Sunsynk are doing it.

Doing what?

 

[RonSwanson]

Attempting to upgrade my firmware.

So Sunsynk is to blame for that?

 

[jezzad]

Here I sit, inverter battery and all components ready to go. Install due today and cannot for the life of me find any cabling in Cape Town.
