Hi, good vid, review and info. I did see a comment from Sigenergy on another video where they said, they like you to put a small roof over the inverter covers you were complaining about to cover this vent area as insurance against leaf or sticks, dirt, bugs, etc, getting into that vented area on top of the system, I can see why now, and agree with your comments. Cheers
Carefully use vise grips to hold the dynabolt thread end without burring and back off the nut. Use a prybar to lever under the washer to apply more sleeve locking force and at the same time try unthreading the nut all the way to the end of the thread. Use a centre punch with sharp hit to release the dynabolt. Clamp the sleeve onto the bolt thread with vise grips and pull out.
Nice review. The EV DC charge module sits in/on the battery/inverter stack - which is not much good for EV charging unless the stack is located near where the car is parked, e.g. in a garage/car port.
Thanks for the video. Do you have a website with prices for solar + battery packages ? I'm looking for quotes for a new system install in Hamersley WA 6022 thanks
Hi Thanks for messaging me on Facebook, for others reading this no I don’t have a website anymore and I don’t have a price list as such due to all jobs being unique. Please feel free to email me at jason@jeswa.com.au Cheers
just checked and tengen was approved on 9/1/25 by SAA. I have some shade on the roof and I thought 6x 4 port micro inverters can handle 24 440W panels can you recommend a brand and is that the best way to go. The other thing I noticed in you review is the panels where arranged in several directions, is it better to have them all pointing north if possible or is half east and half west acceptable. The only other thing is thank god for Australian RUclips reviewers they are the only ones that show all the gnarley bits and give genuine useful information. Other countries (you know who) seem to think the review is about them more then the product so again thanks
Excellent video. Can I get your opinion on your choice if you were to install a single phase battery system in your own home - Sigenergy verses Tesla Powerwall 3. Thank you.
All current generation GM EVs support Vehicle to Home and it has been activated for use. At least in America, I don't know the status of the software in Australia.
Thats awesome, in Australia we are still waiting to be able to do V2H and V2G. As far as I know only the Nissan Leaf has the ability to do it in Australia as yet anyway. Apparently with Tesla though its just a different software that isnt available to us as yet either.
Great video, very informative. I am looking at getting a single phase home battery system, tossing up between the new Powerwall 3 batteries and the Sigenergy system. What was the capacity of the inverter you installed? Must have been one of the larger units to handle so many panels. I think that system you installed with almost 20kW of solar will still have a lot of power exported with the 8kWh battery or even up to 24kWh. In NSW we are limited to just a 5kW inverter on single phase.
Thank you. That one is 15kw three phase. Export limited to 1.5kw. If you are single phase and have an existing solar system I would go Powerwall2 still.
Is this system automatic switch? I.e does it switch from on grid to off grid by itself and back if for example it detects that there is no power or unstable power on grid, so it switches to off grid supply and if the power is out on the battery, it either switches to on grid if there is power there or it directly inputs through the solar supply. Or if for example there is excessive energy after the battery is full? What does it do if it can no longer store that energy or send it into the grid?
I have a 3 phase string inverter with 8kw of panels and a second 6kw system with Enphase iQ7As. Can I get a Sigenergy battery without decommissioning my existing inverters
I think more people will seel this DC charging opportunity when the power providers move to variable export limits during the day, and you won't be losing out on the DC side of the system if your charging a car before conversion losses to AC. Will be looking into Sigenergy for my installations in 2025.
Very good review. I 'm glad you reviewed the quality of housing etc. and compliance of certain components.
Very honest review. Just what we want to hear. A BIG THANKS.
Thanks mate 👍🏻

You did a good job

Yep tried all that, they were bound up and going nowhere. Thank you for the tips though 😊👍🏻

Yes valid point 👍🏻
Great video. Interesting points about the DC charger and the circuit breaker. Can both be deployed in a modern single phase installation?
Yes, however single phase Sigenergy still not approved for use in Australia as yet I believe.

Great video - just for info the Kia EV's offer vehicle to load, although I've never tried this with my EV6.
Yes but only with a 240v adaptor power socket that you plug into the vehicle I believe👍🏻
I’ve heard really good things about them.
Edit… oh bollox… those bolts!

If you go into settings and tools, then app settings, then notifications, you can select Go-off Grid as an alert
Perfect thank you, I believe that may have just been added to the App.

A good very in-depth look.
I disagree though the sungrow Sh15t(20,25) model inverters are three phase and do have UPS switchover of a slower 10 ms.
thank you
I dont believe the Sungrow has the same capacity when islanding but I will check thank you

Or if for example there is excessive energy after the battery is full? What does it do if it can no longer store that energy or send it into the grid?
Hi yes all automatic between off grid to grid tied. If the battery is full and there is no grid the system simply ramps down solar production.
Hi. What’s the largest single phase inverter they have currently?
Hi
12kw single phase.
@@joondalupelectricalservice3201are the 8 and 10 kw inverters able to be installed in qld?
I have a 3 phase string inverter with 8kw of panels and a second 6kw system with Enphase iQ7As. Can I get a Sigenergy battery without decommissioning my existing inverters
Yes, its called ac coupled solar and is measured with a ct and controlled via frequency shifting from the Sig inverter.
Stainless steel they luv binding up
The EV DC charger is too expensive. I can get 100k km of range on grid power for the price of the DC charger. That just doesn't make sense.
It makes sense if you want to charge from your own solar power, not everyone makes these decisions based on financial benefits 👍🏻
Also take into account its V2X capable, having a backup/off grid option to use your EV battery is a massive bonus
And sell power back to the grid at high peak power FIT prices with Amber with V2G
I think more people will seel this DC charging opportunity when the power providers move to variable export limits during the day, and you won't be losing out on the DC side of the system if your charging a car before conversion losses to AC.
Will be looking into Sigenergy for my installations in 2025.
