  1. @phil.g00 Thanks for sharing your experience, learnt quite a bit more today
  2. Only had our system up since mid June so early days but from what i've seen so far, i'm inclined to agree From what i've seen of our Winter figures, I could comfortably add another 2 strings on the roof and still be well within limits of my MPPT Want to run the remaining "seasons" and look at the data - will then figure out if we can add more panels for different times of the year
  3. Hi, yes. The original 6 string are on the roof of our garage oriented NNW. The plan is to add 3 strings mounted vertically on the side walls of the garage, 2 strings facing East (morning) and 1 string West (afternoon). I realise that if all the strings were mounted on the roof at same angle etc, this would exceed the rating of my MPPT. The thinking is that early morning, the East strings would be pushing out close to max while the Roof strings are only starting to "warm up". As the East strings start to drop off, the main roof strings would pickup where they left off. Pic taken at 9 am with PV sitting around 1.9 kw
  4. Love it - we heading into our cloudy/rainy season shortly
  5. 100% The result i'm hoping to achieve is something similar to the pink and green curve in your pic Thanks for your thoughts
  6. I will be making a custom bracket to mount these so they will be well away from the eaves and this shouldn't be a problem but good to know, thanks
  7. Midday is sorted, we mostly getting more PV than we use, getting an extra kw or thereabouts at 8am is going to be really handy, keep the ladies of the house happy since I have instructed them to only start their work from 9 onward - didn't go down to well <g> Going to go for it and monitor carefully - winter should be within limits, summer could be touch and go - if we get to close to the limits, can always disconnect a string, only use it for winter
  8. Thanks Phil All strings will be same specs panels - 6 strings of 285w panels and 3 strings of 280w Original 6 strings are on the roof. The new one's will be vertically mounted on the side of the building so they will only have direct sunlight from mid to late morning
  9. Hi Speedster That's what i'm thinking. My setup is Multiplus-II 5K/48v. Strings are 3 series to SmartSolar MPPT 150/100
  10. Good day all, Current setup is 18 x 285w ArtSolar panels on garage roof facing slightly west of north. Thinking of adding a few more panels on the side of the garage (vertical) to boost early morning and late afternoon, 2 strings due east and a string due west. Artsolar don't offer the 285w any more but have 280w on offer - specs attached. I think I can use the 280w panels with minimal effect but would really appreciate any thoughts from someone more knowledgeable than me. Thanks in advance
  11. Mmmm, makes perfect sense... - this is why this forum is so great - Thank you! Sooo, with this in mind, I have re-jigged the layout and propose to have 1 additional string facing E with the original 3 strings on the roof. Without an E string, by my very rough calcs, we would only have panel power from about 7:30 onward in Summer, probably around 9:00 in Winter. However, with the E string, we should start pumping possibly as early as 5:00 in Summer, Winter around 8:00, possibly earlier Late morning onward, E string will drop off so MPPT shud be happy As for a W string, an absolute winner in Summer, Winter not so much due to available mounting space/angle etc. gonna have to come up with a plan down the road.. Thanks again, have a great day
  12. Ok, makes sense, thanks @phil.g00 Other than having to save for the extra string/s, the spreadsheet seems to be happy with 5th
  13. Apart from doing a lot of great reading, have a question re: Panel config and MPPT Using the Victron spreadsheet, starting with 15 x 285w panels, 3 strings of 5 - this is within the specs (V, A and W) for the 250/100 MPPT If I decide down the line to add a 4th string, the result shows ACCEPTED and Amps "limited" as per attached snap... Is there cause for concern/risk running MPPT at max Amp limit? Thanks Graham
  14. Good Day All, Firstly, huge thank you to all the folks on this forum. I have been lurking for quite some time and have learnt a huge amount from the comments and advice offered here... We are based in Outer West Durban, planning to take the Solar plunge and would appreciate any comments/advice in this regard. Our phase 1 will still have Grid available with change-over for Genny. Phase 2 will be off-grid, Genny as backup - Proposed setup: - Victron 5kVa MultiPlus II - 16 x 285W ARTsolar - 4S4P - 4.5Kw - SmartSolar MPPT 250/100 - 2 x PylonTech US3000 3.5Kwh Stove is full gas and in the process of converting Geyser to Solar Busy gathering quotes for the above - was wondering where/who might be a reputable supplier for PylonTech.? Thanks in advance Graham

    Axpert 5kW

    Hi Cvzyl Just recently started on this solar journey and have no idea as yet what my needs are - just ordered a power moniter to answer these questions On the surface it seems that yr Axpert would be a good option from me to get my feet wet so to speak at a reasonable price Can you provide further detail on the model, specs of the unit you have on offer, assuming it's still available Many thanks Graham
