  1. Richard, you're right, and you're wrong... Some of us saw this trainwreck coming a long time ago and started working on our own solutions. Becoming power (or water) independent is a long and gradual process to which you must devote decades. We also may or may not have had a long history of trying to sway official policy and direction, to little effect. If you wait for policy to shift you should get used to cooking over an open fire and going to bed when the sun goes down.
  2. OK, so I'm imminently unqualified to enter into a technical discussion on this... but... As Malcolm explained it to me... the Sinetamer monitors the incoming sine waveform and as soon as the waveform starts to trend upwards (ahead of the coming spike - I'm led to believe that this is measurable) beyond a set parameter, it cuts the link!
  3. Can't say. Was recommended to me by Malcolm Koertzen from Segen. They don't supply Sinetamer so would appear to be neutral (groan) in this.
  4. OK. Found the info. The product name is SineTamer. Speak to Marius at Adriatic power 082 889 3663. https://adriaticpower.co.za/sinetamer-electricians/
  5. Couldn't agree more. I started with a 2Kw Growatt direct inverter and 8x250w panels. This allowed me to cut 10kwh per day out of my bill, and learn a ton of lessons. I added a 5Kw Goodwe, 2x2.4Kw Pylons and 22x250w panels. Recently put in a further 4.6Kw Kodak direct inverter and another 12x330w panels. All three systems entirely separate but linked to my mains. If one or even two go down or need to be decommissioned it's no biggie. It's not the most economic way to do things, but it worked for me and allowed me to experiment.
  6. Hmmm... so let me tell you what happens to buried tanks when they are empty, and it rains heavily. Buoyancy happens! They rise up out of the ground like spirits from a graveyard on Halloween (topical, see?). Don't ask me how I know this.
  7. OK... so I'm maintaining a watching brief on this one. I've not even updated the software on my Goodwe 5048ES yet, and draw almost zero data from it. This is a hurdle I have to overcome sometime in the future (after connecting up my 5th array of panels, and finishing off the drip irrigation system in my vegetable field, and the plumbing from my well to the main water tank, and, and, and...). I'm hoping that some clever guy is going to set himself up as the Goodwe expert and I'll be able to hire him to come do all of that for me
  8. They'll take a couple of weeks to get in synch with each other.
  9. Guys... If you're sitting on the fence... JUMP! The very best way to learn is to just start.
  10. Are they connected in series or in parallel?
  11. I see the City of Joburg and all of it's 'services' (water, electricity, waste) now style themselves SOC (State Owned Company). What the hell? They are paid for and owned by the Ratepayers (you and me). They are not supposed to turn a profit. And yet they are run 'for profit'. They NEED to sell you electricity because they turn a large profit on it! They would rather see us sit in darkness than sacrifice a revenue stream.
  12. Flying in the face of the national crisis which is the failing of the national electricity generation capacity, the refusal of national and local authorities to gratefully accept ANY extra watts flowing into the grid by over-producing domestic generation systems is illogical and counter-productive at best, and treasonous at worst.
  13. Yep. About 5 or 6K a unit. At the end of the day still cheaper than blown inverters.
  14. A neighbor tells me that he once had a chunk of concrete about the size of a 5l paint can lying in the bottom of his pool (with a corresponding hole about a meter below the normal, now drained, water level). It looked for all the world like a cannon had blown a hole in his pool, from inside the earth! Eventually they figured out that there was a major lightning strike on the Berario side of the koppie, and the current had travelled through the ground and decided to pick his steel reinforced concrete pool shell to reappear through. Bizarre. I had a tall silky oak in my driveway literally
  15. I sit on a mound of dolorite with thick iron veins running through the rock. One of the highest points in Jhb with crisp, dry air. The lightning here is epic.
  16. I'll try remember the name of the product again. My mind is a huge pile of unordered factoids. They occasionally pop up at the most inopportune moment. The way the product works (as I alluded to) is by monitoring the waveform of the incoming power and when it identifies a certain pattern of buildup it opens the circuit before the voltage surges. Malcolm at Segen told me about it.
  17. Earlier this year I had a major lightning strike on the koppie across the road from my office. It hit me through the earth and blew EVERYTHING, Main DB, electric fence, cameras, pretty much anything plugged in... also my two (two month old) Kodak 4.6Kw direct inverters (through the connection to mains). Blew them internally beyond repair. Insurance (eventually and reluctantly) replaced everything. I had a long chat with the technical manager at Segen Solar and the only thing that can apparently arrest a lightning spike coming through the earth cable is a piece of equipment that can sense th
  18. I'll see your 5-8Kw, and raise you... Currently I throw away 17-20Kw per day. But yesterday, in Joburg, I only just filled my batteries enough for the night. Lesson: Have more than more than enough! I'm going to connect up another 2Kw per hour array (array #5) right now. (Damn... this drug...)
  19. Hi All, Who repairs Voltronic local to burg?
  20. I have a Goodwe ES5048 running the batteries. It communicates with the batteries, but I believe that the Pylon Master battery (the 3000) runs the show. They discharge and charge all together. I started with two 2000s and then added another two 2000s (second hand/6 months old), then added a 3000 after about 3 or 4 months so I can't really judge how they perform. The Goodwe app tells me that the battery bank state of health is 98%.
  21. Yep. Almost a year on and it's working just fine. Will add a second 3.5 shortly, but I've yet to discover that I run short during the night... if SWMBO can be convinced NOT to put on the dishwasher at 17h30 (2 and a half hour wash cycle).
  22. Indeed. Now let's work our corner of the problem.
  23. Agree 100%. I think De Ruyter is actually 'managing' the situation as opposed to letting the situation control him. I also feel that Gweezy, and the NEC (who pull his strings), are what is hindering us all from assisting to solve the problem. All that is required, as you say, is the stroke of a pen. The problem is the complex network of patronage and corruption that is required to pick up that pen.
  24. Climate 'Science', as we have it today, has become a multi-billion dollar industry. The climate has ALWAYS changed, and will continue to always change, regardless of puny human activity. Climate change predates the appearance of humans on this planet by millennia. The notion that we have a discernible effect on the periodic warming and cooling cycles that the earth experiences is presumptuous and preposterous. All the 'real' scientists (actual scientists, not those who had a choice between studying 'climate science' or gender studies at varsity) scoff and disregard the 'evidence' of anthropoge
  25. The "Climate Scientists" they reference are known to us by other names... charlatans, conmen, shysters, crooks, liars, and other less pleasant epithets. The entire anthropogenic global warming hoax is about as scientific as ducking witches to see if they float. Meh!
