  1. 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.
  2. 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 other hand put the dishwasher on at night earlier this week. tsk tsk.
  3. 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.
  4. 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 was not accurate (shows constant 3.91kW for the 6.5hrs duration but when actual was ~3 to 8kW). It just logged that one data point at 1:30pm then nothing since. The solar web iphone app history page is still showing yesterdays history so is even worse than the website. I've contact my installer and he's not sure what the problem is. I'm suspecting my wifi as the inverter is on the edge of coverage, but the fact the live data always seems fine makes me think not. any suggestions?? anyone had similar issues in the past or lately? cheers
  5. 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. It seems like it. I signed up yesterday. My only gripe at this stage is the Fronius solar web app, and a weird problem with data logging. Yesterday the history logged fine until ~7am then just stopped logging until ~4pm, at which time it updated the 7am to 4pm data and continued to log fine until around 7am today then stopped again and hasn't -restarted. I suspected issues with my wifi connection to inverter (it's on edge of coverage), but don't think it's that since the live data is always showing accurately, including times the history isn't logging.
  6. 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 due to single phase so there's a bit of lost capacity, but probably not too much on average. Now I just need to decide on energy retailer. I'm currently with origin so checked with them. Origin 'Solar boost' plan is as follows. Seems about as good as I'll get for FIT in VIC FIT 15c, no cap, 12month supply rate 30.72 c/kWh (0% disc) supply charge 114c/d
  7. Water heating is gas storage unfortunately. A change to elec might be on the cards once I have solar. House heating is: Gas ducted (whole house), Reverse cycle (main living room), wood burner (main living and rumpus rooms). The gas ducted does a poor job of heating the main living area so it's usually set low (~15deg) to keep the place from getting too cold and we use either the wood burner or air con for that room. From the sound of it there's not much need from the grid so I wouldn't expect to make much money that way. I've been thinking along those lines too but re-glazing even the main rooms would cost a small fortune. what's the best way for me to keep track of consumption, or find out what it has been historically? will my provider give me detailed info? thanks for the input guys. thanks for the input @marc and @rmpfyf
  8. I'm not sure exactly what you mean by that so I'll just explain what I'm generally hoping to achieve by adding a battery, be it this VPP through origin or otherwise. - make better use of the power generated by my panels. eg. give me the ability to consume 'my' power outside of the sunny hours, rather than receiving a pittance through FIT's. That battery will not cover all my needs all the time so I'm happy to pay for power from the grid for any shortfall, expect the system should draw from the battery before taking any power from the grid. - I want the battery system to power everything/anything in my house, within reason of course. Once the load exceeds the battery/inverter 5kW discharge limit the grid should make up the difference. I'm not sure what would happen if the grid is down and I'm consuming more than 5kW at the time.
  9. I came across this Virtual Power Plant scheme that Origin energy offer. https://www.originenergy.com.au/solar/panels-batteries/virtual-power-plant.html In short, you get a discounted price battery and the power co can draw from that battery whenever they want (has never happened in last 4yrs apparently). You get $ credited when they take power. I'm tentatively considering it for my place (have another topic on that here) so made online inquiry yesterday, got a call back quickly and received the quote today. System Cost $15,817 [ 6.6kW Panels (Trina 370w) + 9.8kW battery (LG RESU10) + 5kW Inverter (SMA) ] Less: STC's ($3222), Gov Rebate ($1850), Gov Loan ($1850) Total Payable $8,895. 24 month interest free payback on the lot. Note: They do a 6.5kW battery but sales rep suggested bigger when I mentioned I want all my house circuits off the battery, not just the essentials. (I'm not sure this up-sell was necessary). I'm keen to hear general opinions in this type of setup, and also the quote I received. cheers
  10. Received the quote for the bigger system, consisting of 28 × 370W Panels ( LONGi or JINKO ) + Sungrow 8kW inverter Subtotal $12,175 135 STCs 7 × $37.00 −$4,995 Victorian SolarPV Rebate −$1,850 Victorian SolarPV Loan −$1,850 Total inc. gst = $3,480 up front (post rebate and loan) => total out of pocket = $5330) So, that's a $2280 extra over the 5kW system using the same components. I reckon I'll go for it.
  11. That'd make my blood boil. Seems like a great way to maximise the benefit of your solar. Now if only the EV batteries could be used to power your house!!.
  12. Company is Pristine Solar (came across the deal on ozbargain). yeah, most panels I can afford now is my new thinking. We have the $$ available so it's better to invest in saving money than just offsetting the mortgage. I guess I could afford and have room for more than 8kW of panels, but I think returns would be somewhat diminishing as I'd start encroaching on areas that get partially shaded. Fronius adds another ~$1K on the Sungrow. I did a bit of reasearch into the sungrow and it seems to be one of the better cheap inverters and reasonably well regarded so I think I'll stick with it. another change I was thinking is for Winaico panels. Partly because the better warranty, performance, but also because they offer a 2yr 'insurance'. We had 2 cars written off due to hail storm in Jan so I'm worried how panels will hold up.
  13. I'm now wondering if I should increase the system size and go back to a split design. eg. 8kW with 16x330w panels on east side and 8 x 330w on west side If I'm being realistic I don't think we'll be very good and changing our usage to suit mostly morning energy production, so some on the west side would be good. It might mean I need to trim a few tall trees nearby to reduce the shading, but that's OK.
  14. I received my quote yesterday then tweaked it a little to change layout, inverter and panels . Their proposed layout was 10 panels east side + 10 west side, but due to the west side being much more shaded than the east I thought it was best to keep them all on that side. Panels were changed to higher output (18 x Jinko 370w panels) to allow all to fit on the large south east area of the roof. Inverter changed on installer recommendation (Sungrow SG5K-D inverter 5kW) . Total system = $8082 86 STCs = -$3182 VIC PV rebate = -$1850 VOC PV Loan = -$1850 Total up front = $1200.
