  1. Yeah thats what I'm getting at with the extra heat storage capacity being useful, if you store 300L at high temperature (generated during the day with solar) than drawing e.g. 1 or 2 showers from that after sunset will still leave you with lots of hot water at decent temperature and no need to start heating from the grid before the next morning. While with only 200L you might not have enough and might need to start heating from the grid after usage. A larger capacity (within reason) is therefore quite desirable and compliments any kind of solar water heating (IMO at least). Geyser 1
  2. Just as a follow up to this, now that I actually pulled the trigger on something. I did finally track down an option, Tecron will actually "custom" make a geyser with two element positions (one at bottom of tank, one at middle of tank) if you ask them. It ends up at R9500 for a 200L geyser with two elements, this is a bit pricey but I guess there are (depending on your opinion) some added benefits to copper, not having to keep changing the anode etc. Another nice things is the tecrons take a standard "1 1/4 inch screw" type element, which many low voltage DC elements are available for o
  3. I was never able to track down an off the shelf part for this, so I'm pretty sure whats in the photo there is a custom made part. The best option for two elements seems to be to just add an additional pre-feed geyser or similar
  4. Does anyone know of anywhere selling DC rated geyser elements in the country, other than the geyserwise ones? The only other place I can find is elexco (no stock) Yes I realise that regular AC elements can be used with DC current as well, but the output of these is reduce quite a bit by lower DC system voltages, especially as we are a 240V country with our elements designed for 240v. So specifically wondering if any 48V or lower elements are available.
  5. Managed to locate at least one local place that has these now: https://www.lumaxenergy.co.za/product/lm-cgw-2/ https://www.lumaxenergy.co.za/product/lm-sgw/
  6. I find this a tricky one. What I like about pylontech is that they are clearly a solid product, they're generally known to be good with quite widespread usage, with independent tests in which they do very well and outperform a lot (most) of the other lithium batteries tested. I'm very happy with the one I have now and strongly considering to just expand with them, they're a solid product. I feel like I can buy a system that will use them right now, punch the numbers into my ROI formula to see what ROI will be like over 10 years and expect them to actually last 10 years, and that if they d
  7. There are solutions to ensure anodizing doesn't cause a problem and that all panels/mounting have a conductive connection, however they don't seem to be very popular or readily available in the country for whatever reason. Or maybe its just a case of people not being aware that it is an issue or that there is a solution? http://www.we-llc.com/products/weeb-washer
  8. Busy shopping around for panels, ideally looking for 310Wp upward (400Wp panels would be nice). Best price I'm seeing currently is in the R4.80/Wp excl.VAT region - was wondering if anyone had run into any really good prices recently
  9. Yes CBI, purchased through cronlec but likely most electrical places can organise them
  10. No experience on these specific panels but I've had other artsolar panels since 2015 and can't find any fault with them
  11. Not at all, 2 seperate elements (quite common overseas; seemingly incredibly rare here): 'Dual' elements on a single 'boss' (some small market availability here in various shapes/forms):
  12. Other than generally being considered more efficient for various other reasons (and thus more common overseas) In the case of solar two elements makes it easier and cleaner to have one element powered by solar and one by mains, with different temperature settings while still being appropriately sized. This is how most people who dump excess solar as heat seem to do it overseas.
  13. Somewhat related to this discussion, and also a long time coming: https://www.pcworld.com/article/3518831/how-intels-changing-the-future-of-power-supplies-with-its-atx12vo-spec.amp.html
  14. Does seem like the way to go, looks like two smaller geysers barely costs much more than a single large one, and its kind of neat in a way having the two mostly separated from each other. I'm convinced Now I just need to decide which of the dozens of potential options for feeding PV into the PV one is going to be the most sane.
  15. Yeah, I've seen both of these, neither of them is really as good as an actual unit thats just designed for two elements though. Also from both a safety and efficiency perspective I'd (personally) like some decent space between the two elements (wiring further apart and so on) I guess the other option and probably closest I can get to a proper two element geyser, is to go for two geysers that just connect to one another.
