  1. Had our internet go down for a few hours once, and data obviously wasn't logging. Internet back, and a few hours later the data was uploaded, so yes it does seem to store and send later - a few hours worth at least. But better someone really in the know answers this in more detail...
  2. Yes, I am very happy with the Goodwe (now three months running), but do wish one had more configuration options....ce la vie, answers to another post of mine here had warned me about this lack of Goodwe customisation; although very happy I do find myself dreaming of a blue upgrade p.s. when I have some time I will try set the battery to "other" and manually see what parameters I can set - SOC shouldn't be too difficult to limit with a reduced voltage (please anyone if I'm being an idiot with this comment / assumption do let me know). Will revert back with my findings...
  3. Is there really no way to limit with the Goodwe? What about setting the battery as "Other" (not specifying its a Pylon) and setting custom parameters? Or is it rather recommended to stick to setting specifically Pylontech (maybe one needs to set this for correct communications with the BMS?) Ultimately I really would like to set the battery to charge only to +- 80% (with on grid discharge to 40% DOD). This will keep the battery at between 60% to 80% while connected to the grid. Furthermore, I'd like to limit the charge / discharge during grid connect to only 15A or so. Wort
  4. Back to original question - Is it better to cycle (exercise) a Pylon, or keep it charged? (For this question please disregard Eskom savings, this is purely a question of battery longevity). They say better not keep it at 100%. No problem to keep it at 50% - 60% for extended periods... To phrase it differently - what degrades a Pylon more, keeping at high charge or cycling up and down to say 60% daily?
  5. YES, love your work @Kilowatt Power, that's brilliant!
  6. Because the pool pump is, unfortunately, on the same circuit as some outside essentials...but I'm not too worried about that, it's a very efficient "multi-speed" pump (around 300w continuous) and will obviously run only during the day - obviously a cloudy day will call for it to be switched off.
  7. Hey guys, What have the clever okes out there done to be notified when there's load shedding? A decent hybrid setup automatically kicks over to battery when grid supply fails, which is brilliant! However, only the non-essential loads get kicked off, most of which we never monitor... My issue with this is: You'll happily continue running the pool pump and other appliances which drain the battery unnecessarily. More importantly, the maid unknowingly plugs in the iron for example, which is beyond the current rating of the battery. So, I'm thinking a 2 stage warning system:
  8. Hey guys, Just a quick update on the above: I had an old pre-paid meter lying around which I re-commissioned and wired into my panel for 2 weeks for testing. End result: Goodwe Smartmeter with CT-clamp is about as accurate as can be! Efergy Engage CT-clamp meter is completely unreliable - I could live with 5%, maybe 10% out, but the Efergy over-reads by anything between 10% up to 100%! Municipal Meter reading slightly high, may get them out to replace at some point...
  9. Hi Plonkster, What you say about both circuits needing a light makes sense, but that's in contradiction to your original post further up? Your one light on essentials also won't warn the electrician to grid power when he switches off the inverter supply... Anyways, I can have the Goodwe SmartMeters' light act as my "Grid power live" light. Just need to install a "inverter live" light...
  10. @plonkster, to expand on your SOP, what about putting in a single light, difference being that it's mostly off and only comes ON when the grid is disconnected? My reason behind this would be to have some visual warning that there's load shedding, and of course it will double up as an indicator light in case the electrician cuts the grid. A simple relay would do the trick... An additional audible warning would be first prize - load shedding creates an annoying buzzer that you have to acknowledge to switch it off. Anyone know how best to design such a audible warning system? (I pr
  11. Mine is just a single battery, produced Jan this year, so ya I guess it'd be fair to expect that sort of 10% drop since then...
  12. Wow. Interesting, would've thought higher...thx for the info...
  13. Hey guys, Just finished our Pylontech US3000 install on a Goodwe inverter. What SOC do these batteries ship with? Ours was at 50% - would've thought for extended "storage" (or shipping from factory) one wants it charged up to a higher SOC?
  14. Hello all, Goodwe system now running since three months - very happy. Finally took the plunge and bought a Pylontech battery yesterday - a single US3000. The optional brackets are quite pricey and to my mind don't serve much purpose unless you're paralleling a few batteries... For a single Pylon: Is such a bracket necessary? Possibly for cooling, but surely same could be achieved by appropriate placement (mounting) of the battery? A certain supplier tried to sell me a cabinet, saying that the battery warranty is void if not mounted in the cabinet. I walked strai
  15. Yep, that's my setup at the moment till I find the cash to invest in some batteries - Goodwe ES with a couple of panels, works a charm!
