MC Electrical, an installer in SEQ
Old mate must be feeling the pinch lately and has started criticizing any product he doesn't have an agreement to sell.
It's a shame as some of his earlier videos were informative.
It’s a bit like Tesla in the old days, they took an existing product and made it a lot better.
Out of interest, what house battery product was around before the power wall?
LFP batteries are bulletproof, I haven’t heard of any failures even in cars.
Then you haven't looked very hard. BYD LFP EV batteries have failed in OZ and needed replacing.
The failure rate of any EV batteries is generally very low, but it isn't without failures, like most things in this world you always get some duds.
Young company: only two years old.
This is my biggest worry as well. It's a new company, a design flaw that pops up in a few years time could be very costly for them and take ages to get fixed. Think LG Chem.
We are also getting basically V1 of the product, generally these companies roll out a V2 to fix all the things they don't like about V1 and often that isn't backwards compatible with V1.
PW1 was very short lived, then PW2 arrived for ages then finally PW3.
Are we at the PW1 stage or PW2 stage?
All that said, if you have 3 phase, then Sigenergy is the way to go, no questions asked.
The reality is that product development takes time... Regardless of how many geniuses you hire ..
Real world testing brings out the worst (and best) of something.. iterations are required.
The (my) concern with Sig is how young the company is, and what backing support do they have (outside of the CCP – which is not not non-trivial)...
MC is right, it's a risk.
Personally I think it will be fine.
!remind me 5 years.. :P
The (my) concern with Sig is how young the company is, and what backing support do they have (outside of the CCP – which is not not non-trivial)...
Sigenergy appears to already be the best supported Chinese inverter in Australia. I'm pretty certain they have more staff than all the established Chinese inverter manufacturers. Remember, at the moment Sigenergy are not supporting hundreds of thousands of legacy inverters failing under warrenty, they really only have 6 months of sales to look after.
My understanding is that he loves the stuff he sells, everything else: not so much.
Yes MC loves to slam products they don't like, like the Zappi, yet 100ks are installed without issues. Yet they got the only two with overheating issues. (goggle Zappi overheating and its hard pressed to find a unit with the same issue).

Same, its young. While they might have hired/been born from some great engineers. 2 years is a short time for a development and testing cycle for a product like this.
The 2 year warranty on the gateway is a valid concern when others like the PW2/3 come with a 10 year warranty.
Personally I think it will be fine.
If I had 3 phase, I would risk it. If I had single phase, I would go with the PW3. But that's just me.

Easy to do when as you said
they really only have 6 months of sales to look after.
The real test will be in a few years time when things start to fail and they are looking after a lot more installs. At this point in time, all these installs are very 'personal' as we have seen from some of the MD comments here.
We've ruled out Tesla anything.
Agreed, I dont hold it against current Tesla owners of course, but now that a certain individual seems to have lost the plot entirely, I wont be sending any more cash his way.
You could call that hypocritical given I bought a BYD and am looking at Sig for a BESS...
Aren’t people fickle :P

Ahh yes, the CCP has fine examples of human rights and doing the right thing.
No company is perfect, so choose your poison and go with it.

Same – plus to get anything similar to the equiv of my 24kWh battery I would have had to install 2 x PW3's ($$$$)
The Left-Right political spectrum is a circle rather than a straight line. Extremes of both are well.....extreme!!

At this point in time you have to go double PW3, but you would also get double of everything so double solar inverter, double output etc. Which could be handy in some cases.

There is no middle anymore. Both sides fail to see that.

A good thing our <unspeakable brand> battery is hiding/lurking in the garage and not open to public derision ;-]

Please can we just go one thread without this turning into a Tesla vs CCP debate. I have been on WP for over 20 years and I don’t remember it being this divisive. Let’s just talk about the tech!!! :)
Back on topic, what other 3 phase backup solutions are out there? I may just consider moving the whole unit into the garage instead of the south side of the house, but it means bollards. I can make room for it.
At the end of the day they are a young company, but all companies start that way and if nobody supported them then they’d cease to exist. I think it looks like a great product.

I dont think he's necessarily wrong. I'm close to signing up to get a Sigenery battery but I agree with his sentiment about a lot of it. It is a new company and a new product, nobody knows how it will hold up in 7 years time or so. I think they say that the battery is good and they hope to be proven wrong.
I think they are just very cautious with the products they recommend/support and I dont think they can be blamed for that.
The 2y warranty on the gateway is my main concern

Few listed here https://www.solarquotes.com.a

Also remember the extra costs for cabling etc back to the main switch panel.

Agreed, but people do need to be aware of the risks. It's a big outlay for most people. While I don't think sigenergy backers will let it fail anytime soon. They are still very new and very small, so growing pains are to be expected at some point.
The 2y warranty on the gateway is my main concern
I was a bit surprised by this being so short, and I agree with all your other points.
It certainly is going to be a time will tell type of purchase.
MC Electrical, an installer in SEQ, has reviewed Sigenergy system on YT
Watched the video a couple of days ago. Hmmmmm. Not impressed with their attitude towards the Sigenergy system. However, his other videos are generally of a very high standard.
I need some reassurance, as I have ordered an install and paid the deposit.
My Sigenergy BESS is finally about to be installed, now that United Energy (Melbourne DNSP) has lifted the grid protection limit from 30kVA to 200kVA, in line with the recently updated Australian Standards.
I have a 3 phase, 25kW/40kWh, stack on order. MC Electrical's video has not deterred me from buying Sigenergy, even though their issues are somewhat valid.'
Sigenergy have systems installed in many countries around the world. Australia, New Zealand, South Africa, USA as Point Guard branded and other locations. I haven't hear or read about any serious issues with their systems. Only very good news. So by now, with many systems installed, I have confidence that my Sigenergy BESS will perform as expected.
Take a look at this very recent press release from Sigenergy

We've ruled out Tesla anything.
I only ruled out Tesla for my home BESS because it's single phase and I have 3 phase home supply. If Tesla had 3 phase BESS, it would be considered. So it's Sigenergy all the way.
Also remember the extra costs for cabling etc back to the main switch panel.
It’s a new build and just across the wall anyway, so a very short run. It’s just that it will eat into my garage space and also the extra heat in there during warmer months (QLD west facing!). As we all know heat is bad for batteries. The outside wall is south facing with no sun exposure but some exposure to rain. I could build a little cover for it?
Decisions decisions. I’ve got about a month or two to decide before the wiring goes in.

This is the nature of "Product Reviews" from solar installers
Although he does go to good detail and provide good proof for his opinions (or sales-pitch), its like getting medical advice from a pharmaceutical company.
