  1. Hi Gerrie, I connect to the battery fine - I see the green battery icon and can see individual cell temps etc. However, newer versions of BatteryView seemingly show additional info over and above what V2 shows - and I'm specifically looking for event data not appearing in V2 which I'm hoping a newer version will show me. Anyone have a link to a newer version of BatteryView?
  2. Hey guys, I finally got Batteryview running on our US3000A...some questions (@Youda, you seem to be the expert on this :-) I have Batteryview Version B2.0. Seems newer versions give more info, but I cannot find a newer version. Anyone got a link to a newer version of Batteryview? Main reason for connecting via Batteryview was to search the event history / event data, however it comes up empty. We did have the battery shut down once due to excessive power draw during loadshedding - granted, this was a few months ago now, but seeing as no events listed at all I'd have thought it would have stored this event even if old? Reason for wanting to view event history - on our Goodwe, via PVMaster, it shows a recurring Alarm: Error type: BMS Alarm Fault code: 0 Fault Description: Error Clearing (??? What error) Operating mode before error occurred: Normal What the heck does this mean? This fault repeats itself, mostly every hour, sometimes a few hours in between (but always 24minutes past the hour) - no pattern to this one hour vs many hour delay that I can recognize. I was hoping Batteryview's access to event history would tell me more, but as mentioned it comes up empty...Any ideas? Thanks as always... Markus
  3. Hi guys, Weird "error" showing up in our Goodwe alarms. Setup: Goodwe ES with single US3000B (plus panels etc), setup works fine but keeps showing this "error": Fault code: 0 Error type: BMS Alarm Fault description: Error Clearing Always comes up at 13minutes past the hour, sometimes every hour sometimes a few hours in between (see screenshot below). Any ideas?
  4. Interesting story - most of you already know this, but I was dumb struck by the magnitude of the effect... We had an array of 7 panels in series (360Wp each), running just over a year. Yesterday finally installed an 8th panel we'd provisioned for - expecting a 14% increase in yield. Monitoring the PV output this morning, seemingly it was producing extra but wasnt sure and waiting for midday peak - it started consistently dipping around 11am. "Weird, no clouds, what the ???" I thought. It dawned on me - the newly installed panel has a small chimney that may be casting a shadow on the new panel. But surely that can't be? The dip showed lower production than what the 7 panels on their own would produce!!! Surely with shadow on 8th panel I'd still produce 7 panels plus one additional "downgraded" panel??? Anyways, climbed on the roof, and there was indeed a small 8cm by 8cm shadow right at the bottom of the newly installed panel (total array size 8m x 2m, size of each panel 2m x 1m, so the small 8 x 8cm shadow really was comparatively tiny). Long story short, I cut the chimney - no more shadow, and the PV output immediately jumped by almost 25%!!!! (See image below) I understand any shadow will handicap the system somewhat, but didn't realize how much it would actually handicap the entire array! Wow, lesson learnt, if any part of your array gets shadow throughout the day then either get rid of that shadow, or split into 2 or more separate arrays to minimize the effect...
  5. Interesting, thanks guys...why do you say Sunsynk is a better option? What makes it better (besides the price)?
  6. Hi guys, Six months ago I installed a system with the 4.6kw Goodwe (based on the excellent advice I'd received on this forum)...very happy with it! Now a mate of mine wants to install, and I'm suggesting the Goodwe (fits his requirements well as a hybrid grid-tie). But, we all know technology moves at lightning speed...is there anything new on the market that you guys would recommend over the Goodwe? (apart from the previous Victron vs. Goodwe discussion). Cheers, Markus
  7. 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...
  8. 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...
  9. 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. Worth doing to increase battery longevity? Or rather stick with Pylontech battery settings (which cannot be changed)?
  10. 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?
  11. YES, love your work @Kilowatt Power, that's brilliant!
  12. 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.
  13. 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: An audible alarm, similar to a UPS, but which one can "push button" deactivate until the grid is back. ("yes, I hear you, grid is gone, thank you, be quiet now") An indication lamp, which comes on and stays on permanently during load shedding. Even after the audible "acknowledgement" one still sees whether grid is supplying or not. No 2. should be very easy, using a relay you connect the light on inverter power onto the NC portion of a relay, and connect the relay "coil" to grid supply. When grid is present, the relay is switched to NO position, meaning no light, when grid fails the relay flicks back to its standard NC position, voila, the light circuit is closed... No 1. however, similar to No 2. above, but how to wire in a push button deactivate switch? Any other clever solutions you guys have come up with? Cheers, Markus
  14. 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...
  15. 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...
