  1. I think all municipalities are in the same boat. They don't really want home owners to generate their own power, but they can't stop it (or don't want to be seen to be stopping it). They also don't want to see the independent generators that they and Eskom are courting scared off, and they see problems coming with too much power on the grid at the wrong time of day. What they can do is tell you that OF COURSE you can have solar and sell your surplus back (which is the truth) but make sure you'd be crazy to do so (which is the whole truth* I don't think this is an SAn thing BTW. I had
  2. Thanks @FritsS. I haven't noticed any problems. I'm not technical, so don't even know what an acceptable temperature range is.
  3. I agree with this. The reason I don't export - though I could - is that I would have to switch to a different tariff structure that would land me with 6 to 7 hundred rand a month in fixed fees, plus have a two-way meter installed at my expense, and then COJ pay you (IIRC) 0.67c per kw/h. It doesn't add up for me. I would have to export a lot of power to break even on that deal. So better to not export. I do have some sympathy for them regarding pricing. Everybody wants to have a situation like the UK where we have a grid, and, separately, generating companies that feed into that grid
  4. I don't export, but my system is connected to the grid. All grid-tied or hybrid systems will be. And once they connect to the grid they should stay in sync as regards voltage, phase and frequency no? Also there needs to be anti-islanding so that if the supply is cut off, those systems disconnect from grid. In which case the municipality or Eskom is surely entitled to lay down some requirements and check that these are met. Most systems built from brand name components should behave corrrectly, but somebody, somewhere will either try some Heath-Robinson contraption or will bring
  5. Thank you. I was assuming "10MW/h" but the quoted report doesn't say that. You have bought clarification to the argument. As other posters are pointing out, tariffs are everything here. At present, in Jozi, I can sell back to the grid but the tariffs (including the fixed monthly charges and the cost of the required meter) don't make it worth my while, so I don't bother. Even if the tariffs do benefit me financially, City Power / Eskom are going to run into the problem seen in Australia, where they have so much power that didn't cost them much at the wrong time of day that it actuall
  6. Is that 10MW per day? I'd think that's a lot of gear for a house, but a mall or a hospital should find that worthwhile.
  7. I am getting a steady stream of these. They always start after SOC has reached 100% IE I never get them when the battery is charging. Looking at the history, they stop as PV becomes trivial at around16:00. The temperatures shown range from 31 to 48, so I'm not sure temperature is the driver. Should I worry?
  8. OK... so eventually the BYD hardware was reinstalled and the technician who did the job was kind enough to fill in the blanks in my knowledge.
  9. Also I assume I change the battery settings (which I did record) before connecting the battery to the goodwe
  10. I don't want go into the WHY of this, but on the weekend I may have to reinstall a Byd BMS and Bmu as shown here The BMS is the wider bottom box, the Bmu is the smaller box and sits between the BMS and the goodwe. I've got most of the connections figured out. The coms cable between the Bmu and the BMS is missing but I believe that's rs233, easily obtained. I have the cable that runs between the bmu and the goodwe. Then there's the cable that comes out of the back of the Bmu. (see picture I attached) I think this is power. What else could it be? So what do I connect that to? T
  11. The DA in Jhb are not acting on principle. They are opposing the introduction of a new fee for 2021/22 that they themselves tried to impose in 2019/20 when they were running the show. In Jhb they are making a noise about how residents should be incentivised to switch to pre-paid power, but as far as I can tell they have removed those incentives in CT.
  12. Infrastructure, and there is a cost to maintaining accounts and reading meters. Which is why all municipalities should be giving a discount to pre-paid users (increasingly they do not). There are all sorts of costs. Up in Gauteng encroachment onto street power lines by trees has become a big problem and City Power and Eskom are busy trimming in the areas they supply. Not always easy because some of the trees are actually on private property and owners refuse entrance or threaten to sue.
  13. Last thought for now. CTs charge per kw/h is significantly higher than Johannesburg's.
  14. COCT have done a better job of justifying their increases than COJ have. If you think about the sort of things they point out like the number of rubbish bins they deal with per day, then it all looks a lot more justifiable. COJ instead have published long documents full of "international benchmarks" and "best practice" and blah blah blah. You won't understand it, or you'll have fallen asleep by page 15 where they are still dealing with definitions.
  15. Well, City of JHB saying they are increasing electricity by less than the increase Eskom got, but what that really means is that for most brackets on most tariffs the price per kw/h has increased by less than the Eskom increase. Your overall electricity spend may go up by more or less than the Eskom increase. in COJ post-paid users will see only a small increase and scream hooray for the council (or not). But that's because the fixed fee component of their bill is so large already that 15% extra per KW/H will hardly be a blip on their radar. Pre-paid users are going to get hit a lot harder
