Received the complete bill since July FIT change leading to drop in credit. I knew it as calculated based on increased supply charge and lower FIT. Still in credit and have three hours free energy which keep me still happy.
In case anyone wants to join use the referral code as I have gas with them, so it would not be wasted

I'm trying to force overnight hot water heating using battery power only instead of grid.
What's happening is:
Smart device uses grid power, or
Hot water heating doesn't happen overnight and only kicks in when PV produces power during the day
It's beginning to feel like a software/system problem.
CONFIG:
App is v4.0.0
Device Software Version v100R001C21
Energy Saving Mode is Performance Mode.
The Current Mode is "Self-Consumption".
Solar producing source priority is:
Battery level settings: Backup SOC is 5%
Smart Home Device settings tried (with hot water drained earlier in the evening):
Scenario 1: timed start 22:00 / stop 24:00, all days, Energy Source Control: Depends on System. Battery Boost: Yes. RESULT: Heats on schedule using Grid import.
Scenario 2: timed start 22:00 / stop 24:00, all days, Energy Source Control: Battery level control, Activation Threshold 5, Deactivation Threshold: 1. Battery Boost: Yes. RESULT: Hot water system powers on, small draw 0.03kWh, doesn't heat during period.
Scenario 3: AI mode. Ran this for a month. Didn't observe overnight heating from battery only.
In both scenarios, the Sanden hot water wi-fi config is: Time setting: block out period 0/0
HARDWARE:
1x INVERTER: SigenStor EC 15.0 TP AU, FW V100R001C21, SW V100R001C21
3x BATTERY: SigenStor BAT 8.0
PV Panel: 18.05 kWp
Energy Gateway: On Grid
Diagnosis has no alerts. Full report shows all normal, only the lack of ethernet connection is called out (expected)
Smart Home Device: Sanden GAUS-315FQTD 315 lite Wi-Fi heat pump hot water system
I have the battery set as a priority to discharge before grid during peak import times. Yet the battery is only discharging at 0.2kw, yet the importing from the grid is at 1.5kw.
Have played with some settings but nothing changed, set them back to default.
Just wondering if anyone know where this limiting setting could be?
I assume people are having similar issues with pv surplus charging session stopping due to low solar generation and the car closing the session when house load or solar generation drops due to clouds, I have put in a feature request to sigenergy, if this also happens to you, feel free to go give it a like in the app so it gets some attention. See photo for details
Got these errors tonight, and the system went off and on grid multiple times within a few hours. I logged a fault with Ausgrid and they will come and check tomorrow.
For reference, my system is 3 phase, 32kwh battery, 15kwh inverter - AC couple with an existing Fronius.
Meanwhile, I am wondering if anyone has experienced similar issues?
My DNSP keeps sending this command every half hour.
Maximum PCS export active power: Depends on the system
What does PCS means or do ?
I'd love to know what people are generating with their solar array given it's winter and the weather's been fairly inconsistent. I'm in Brisbane, QLD, and have had my Sigenergy setup since March. I've been fairly underwhelmed by its performance, with most days failing to fully charge my stack from solar alone.
System: Sigenergy 24kWh battery, 8kW inverter, 10.34kW solar (largely flat roof).
Keen to hear what people are generating, particularly on a good sunny winter day, relative to your panel capacity.
My numbers so far: June averaged 17.93 kWh/day, July (1st-24th) averaged 19.33 kWh/day.
Hi All,
Firstly thank you for any help on this.
I am experiencing many frequency issues with my Sig system thats tripping my grid breaker and going off-grid.
I have checked with my energy distributor, Endeavour Energy, and they assure me that after monitering there is no voltage or frequency issues outside of their allowed parameters.
Anyone with experience as to what to ask sparky to check, or Sigenergy? Sig say its a grid side issue, even though im not conviced due to my street having many batterys Tesla/Sig and im the only one with issues.
Hi all, just wanted a opinion on a quote for solar panel and battery in Adelaide.
19.11 kW 39x Aiko Neostar3P 490watt panel
18.08 kWH SigenStor Bat
I was quoted for $22500, what are people’s thoughts on this?
Hi. I'm trying to figure out if I'm onto a good thing here or not with my energy plan. I'm hoping someone can crunch the numbers to see if I can do better with another provider
I had a 36kw Sigenergy battery with a 15kwh 3 phase inverter installed 2 weeks ago. I've got about 16kw of panels on the roof. I'm in self consumption mode on the Sig app.
My energy retailer (Engie) pays me a 12 cent FIT all day. The daily supply charge is $2.17 and the flat rate is $0.47 per kWh. There is no TOU tariff just a flat rate.
In 14 days I've only imported 4.78 kw from the grid and exported 312.39 kw
I know the DSC and flat rate are high but getting 12c FIT all day is pretty decent.
I have 24kwh battery system ac couple
I'm not talking about battery price, but installation cost will get the same or less. I also need more wiring?
I'm thinking about to get 9kwh module
Have just started using the ev dc charger and it doesn't seem very good with not drawing from the battery in excess solar pv only mode, is this normal or have I got a setting wrong
Had my system since Apr and seems like the wifi just randomly disconnects every 2-4wk.
Found a YouTube vid which shows one fix which is restarting the battery by turning off the inv and DC switches under the cover.
Was wondering if anyone else had the issue and has a better fix?
Im looking at getting a 25kw inverter with 48kwh battery.
What i am confused about is the installer says the full 63A 3 phase can be pulled from grid to backup (house) and there is only a limit of 25kw when pulling from the battery.
However reading the specs of the gateway it says 30kw limit on backup output and 30kw limit on grid connection.
I want to be able to run a 22kw ev charger and full house load (at times more than 12kw) from the grid during the free eletricity period.
Can I use the standard TP gateway or do I need the C60 unit?
Hello gang.
I currently have a 16 kWh battery, 2 x 8 kWh, and am looking at upgrading it once my new garage shed is built. I am also looking at a new job a couple cities over on a 24 hour roster, and will need to be able to charge about 35 kWh into my car between shifts. Ideally I want to charge it using just solar and the four-hour free electricity tariff I get. Easy if I am working overnight, but slightly tricky other times of the day.
Thinking I want an EVDC module so when the free tariff starts I can just chug power from the grid, especially if I may not be home for the full four hours. To that end I am thinking about getting some more battery modules added to the system as well that can store enough power during the day, and regurgitate it into the car, like a proud parent penguin with its chick. I’m led to understand the current battery modules are 10 kWh, so if the budget goes far enough I possibly want to try and get three added. Believe the limit for modules in a stack is eight, so six modules should be fine as I don’t have the space for more stacks.
Currently my battery system charges and discharges at a max rate of 5 kW. Will adding more battery modules alone enable it to charge and discharge faster? Even on a sunny day, my solar can’t generate enough power in a day to charge a battery that big, so I would want it to be able to charge itself completely using the free electricity tariff like my current system is able to.
Finally, can someone give me an idea how much the EVDC and battery modules are going for today? Would also be handy if anyone knows if battery rebates apply to expanding existing systems or new systems only.
Thanks team.
A quick question about these $200 Amazon referral gift cards. We had our system installed June 10th and used a referral code from on here. The referral section of our profile says we claimed the offer successfully. The T&Cs give a very broad window of receiving it before 31/12/26. Just wondering, if anyone has actually received theirs and how long it took? Hoping to use it to buy some travel supplies before we go away at the end of September. I know the email address I have with Sigen is correct, as they’ve sent other emails since installation.
Hi all,
I'm trying to set up a behaviour under time-based control where this happens:
I thought I'd be able to manage this behaviour by setting up a Charging timing block but limiting the "power from Grid to BAT" control to 0 kW. However, this seems to also prevent the solar surplus from charging the battery and instead it just exports the surplus to the grid. Am I doing something wrong? Is there another/better way to get this behaviour?
Hi. We had a sigenergy battery installed two months ago. We never received any documents relating to compliance or warranty. Everything is running fine, just seems odd to have no paper trail...installer seems strangely vague.
Wondering if anyone else has had this issue start. For the last 2 days my battery automation for the evening export has been ignoring the 2.5kW maximum discharge and dumping the battery to the SOC minimum at 5.0kW.
Side note…I wish they would leave things alone. Sig seems to just be changing stuff for the sake of changing stuff.
