  2. Welcome Bazzle - enjoy your stay and I look forward to reading your contributions.
  3. We have had our 3.4kw system ever since solar was introduced commercially here in Vic. Ours was installed back in Jan 2009. We have 2 strings of 10 x 174w Solartech and Topray panels running into 2 x CMS2000 invertors giving a max of 3.4kw normally. Had no real issues with the set ups at all. I do have a spare CMS2000 but not needed it yet. Both invertors have an small aux fan under the heatsink that comes on when inv reaches 40c powered by a 12v panel.

  5. I have the 5kw Sungrow inverter and have no problems at all so far I have also learned recently that if you add a seperate ( I think it’s called ) a Sungrow S100 Energy meter. With this extra meter you can also see via the app the export to the grid amount and many other features over the standard dongle Without the meter you only see your input from the panels to the inverter
  6. Have narrowed my search for a solar system down to 2 suppliers, who would you run with? 13.2kW System Option 1 REC panels Sungrow inverter Master installer certified $10990 Option 2 Canadian Panels Fronius Inverter Uses local, well reviewed installer $9680 Both are semi-local companies who have been to site to evaluate the install and spent time determining my needs. The REC panels from option 1 have a longer warranty (25 vs 12) and the fronius inverter from option 2 has a 13 year warranty vs 10 for the Sungrow. Option 1 comes with Solar analytics, a
  7. A couple of news stories that indicate that solid state batteries are close to being a reality in EVs The expectations are shorter recharge times and longer distance travel time Samsung https://www.whichcar.com.au/car-news/samsung-solid-state-battery-breakthrough Toyota https://thedriven.io/2020/12/14/toyota-plans-revolutionary-solid-state-battery-for-2021/ Other news https://www.wired.co.uk/article/what-is-solid-state-battery-toyota-dyson https://insideevs.com/news/465188/nio-150-kwh-solid-state-batteries-2022/
  8. Thanks Jason Its a wonder why they haven’t contacted me about about a smart meter upgrade after installing the new solar system Looks like I have to take the initiative and contact them Paul
  9. It would be a newer, more modern meter that would be installed. When I had our system installed, before it was allowed to be turned on I had to have a new meter put in. The old one was a digital Time-of-use one. Origin put the new one in, at a cost of $45. The new one is read remotely online, no need for a meter reader to come around. On the Origin website, with the new smart meters you can see your daily usage, and your daily feed-in. They’re well worth having, especially at the very low cost that Origin charges for the installation.
  10. I thought that more information is needed When the first solar system was installed about 15 years ago the analogue spinning wheel meter was replaced with a digital display meter But the digital display meter still needs to be read manually I have found and just read some information about the smart meters Here - https://www.aer.gov.au/consumers/my-energy-service/smart-meters I’m not sure if my current digital meter allows me to allocate use of solar power for household use - I have the inverter set to owner use and export the rest - but not sure if
  11. Going by those numbers it means that your decision to install a solar system was justified As was my decision to upgrade my system from an outdated installation to a new more efficient system
  12. I was wondering if I should have a Power company ( in my case Origin ) smart meter installed We have a small problem - I have a dog and the meter readers will only come into our gated yard if the dog is locked away to read the meter If I was to have one installed they can read my power usage from outside at any time Advice needed * I’m not sure if the power company charges for this meter to be installed * Can I use it to check my own power consumption * Is it a better system than the current manual reading way * And is it secure - just saying “ can it
  13. I'm still waiting for the end of my first billing period, but it's looking pretty good going by the Fronius data. 8.2kW inv, (limited to 5kW export). Since 18/11: PV production = 2,440 kWh (~39 kWh/d average , ~65 kWh/d peak) Self consumption = 526 kWh Total consumption = 981 kWh.
  14. Analysis for the full year of 2020 Total Production: 12.882 MWh Total Consumption: 12.931 MWh Highest Production Day: 59.3 kWh on 11th November Lowest Production Day: 1.9 kWh on 26th July Daily Averages - Production: 35.2 kWh Consumption: 35.3 kWh Own Consumption: 16.6 kWh Export: 18.6 kWh Import: 18.7 kWh Cost: $1.88 Yield: 4.1 kWh/kW
  15. Analysis for December 2020 Daily Averages - Production: 36.0 kWh Consumption: 34.7 kWh Own Consumption: 18.0 kWh Export: 18.0 kWh Import: 16.7 kWh Cost: $1.71 Yield: 4.2 kWh/kW December was a pretty cruddy month weather-wise, with only 90% of predicted production, 1,115 kWh against a predicted 1241 kWh. The best day was December 7th with 58.3 kWh produced. The worst day was December 19th with just 11.1 kWh produced.

Analysis for November 2020 Daily Averages - Production: 44.5 kWh Consumption: 37.6 kWh Own Consumption: 20.6 kWh Export: 23.9 kWh Import: 17.0 kWh Cost: $0.23 Yield: 5.2 kWh/kW November was 13% better than predicted, with production of 1,336 kWh against a predicted 1187 kWh. The best day was November 11th with 59.3 kWh produced, our second best day since install. The worst day was November 5th with just 6.7 kWh produced. In November we
  17. We have just passed our first year since our system was hooked up. The vital stats are: Total Solar Production: 12.96 MWh Total Household Consumption: 12.66 MWh Energy Exported to Grid: 6.96 MWh Energy Imported from Grid: 6.66 MWh Total value of power produced: $2,766 Highest 5-minute output: 8.35 kW (14 October) Highest daily production: 60.604 kWh (28 December) Highest daily consumption: 90.427 kWh (28 November, the last day of the first year, which was a stinking hot day, and the longest we've ever run the air-con) Highest daily exp
  18. Our system has been in for about 1 week and I've been somewhat glued to the fronius app pondering matters of consumption and production. eg. What the hell are those spikes, what's that ~400w baseline consumption We have an 8kW system but 5kW export cap so I've been looking times of excess production and thinking about what consumers I can move to make the most of it.. It's almost reverse consumption anxiety because it's annoying leaving kW on the table so there's times I want to consume more just to see the system hit it's 8kW potential. My mrs on the o
  19. I think you're right. A home network upgrade is on the cards so I'll run a cable. Thanks for the tip and vid. I checked and it was already ON. The logging does seems better now than the first few days. I haven't noticed any big delays (several hours) in history updating recently, but that might be because I'm not looking at as often now the novelty has worn off a little.
  20. @manchu I'd suspect WiFi connection reliability. I never count on wifi, and always run a cable if possible. My Fronius is hard wired, and I never have issues (unless I'm fiddling, which I'm prone to). Another thing to make sure of is that Night Mode is set to 'ON' in your inverter. If you have a Fronius Smart Meter, you MUST have night mode enabled so your logging works correctly. I've made a little video for you here on how to do it. Cheers, Jason.
  21. I had a system installed this week with a Fronius Primo 8.2 & smart meter and am having trouble with the data logging. Day 1. system online ~midday. Installer hadn't set up my viewing permission so I didn't check data at all. Day 2. Logs fine from start of Day 1 to ~7am day 2 but then stopped logging until ~4pm. At 4pm both the website and app accurately updated the missing 7am to 4pm data and continued to log fine to end of day. Day 3. Logged fine from midnight to ~7am then stopped logging, until ~1:30pm, at which time the website updated but data w
  22. 10.3kW in panels. 28 x 370w Jinko. Yes. To be honest I didn't pay much attention to the export limit but now I'm witnessing the un-tapped capacity it's a bit annoying and has me wondering if I've over capitalized on the system. It's certainly true for peak production times if I can't consume the excess, but there'll be good benefits other times so i'm fairly content. My system was showing ~5kW export from ~8am to 4pm yesterday (56kWh for the day), and no problems producing the full 8kW if I switched AC or another load on to make up the difference
  23. Good on you Manchu. How many kW of panels did you end up going with? The Fronius Primo inverters are good, I have the 8.2kW like you, with 8.58kW of panels. Has the installer set it up for 5kW export limit? Luckily here we don’t have to do that, so with the weather lately I’ve been exporting over 7kW peak to the grid most days, with some over 8kW. That Origin plan looks pretty good. A 15c FIT is about the best you can get at the moment, I think you’ do well. Cheers, Jason.
  24. Updating this thread as my system went in yesterday. A whole bunch of the Jinko 370W panels some optimisers for one section and an 8kW Fronius inverter. I didn't end up contacting your installer @Marc as I'd pretty much decided to go through my cousins mate/local installer if I got a good vibe and a price reasonably close to 'cheap' upstart mob, which I did. He squeezed my install in very soon after VIC lockdown eased (others I know who ordered elsewhere before me are still being told a few weeks), and did a great job from what I can tell. I'm limited to 5kW export d
  25. Well my first year is almost up, and Origin have decided that my 21c feed-in tarrif won't continue. They don't appear to offer any more than 12c to anyone any more. I've run my spreadsheet over all the offers I can find, and staying with Origin seems to be my best option. My new electricity rates will be as follows: 55c/kWh Peak 25c/kWh Shoulder 15c/kWh Off-peak The new contract with Origin will give me a 16c/kWh feed-in tarrif. So now I know that my cheapest power is 15c/kWh, which is during the Off-Peak period. Power from my own solar producti
  26. BYD has a nice feature with their new batteries where the battery is modular so you can add more modules later to increase battery size (although inverters will generally require a certain minimum number of modules to get the required power input). Could also make repairs easier as a faulty module could just be swapped out. BYD - https://www.bydbatterybox.com/
  27. This week we are increasing our rooftop PV from 4.5kW to 10kW, mostly to reduce the load on the battery in winter and also to dump excess generation into the car during the day. We have a 17kWh lead-acid gel battery but the load on it was excessive with our current generation/use. Hopefully that'll change with increased generation capacity. We mainly have the battery to guarantee power for electric roof sprinkler pump, we haven't been able to draw more than 3kWh without the battery overheating
