  1. This is a very misleading statement, no (unless you meant 6mm and not 6mm2 cable)? It all depends on the distance. OP said his distance is 20m, so 40m with negative, at which 6mm2 cable will not be sufficient to provide even close to 53A. Please school me if I am missing the bus here.
  2. I have Hexing sub meters in my shopping complex. When in tamper mode, they cut supply of electricity from the source.
  3. it produced the 24 amps at 25 volts which is much less than the 27-28 it does when all 6 panels are connected. not sure if that matters? so you no longer suspect the cable thickness and its length as the problem? the inverter is rated at 50amp (max 80 amp) not 60 by the way for the panels.
  4. I test both sets of 3 panels. They produced EXACTLY the same amount.
  5. Just two things, panels are rated at 8.67 amp x 6 panels = 52 amps. Three panels easily produce 24 amps. So shouldn't 6 produce at least 48 amps? I will climb in the roof today and measure the distance of thd cable myself as that is such an important factor in my opinion. I have a fuse in my AC DB board for the solar panels and that is it. No combiner box. No protection at the panels in the roof. All "professionally" installed.
  6. I missed this sorry. No he did not. But that is not entirely his fault. I bought my house from scumbag human beings who supplied me a fake COC and then left for Australia. I even out of generosity let the wife stay in my house after it was registered, rent free for a month as her flight was only a month after registration. I only discovered the COC was a fake when I compared it to what is actually in the house and the current state of the DB when the cover was off. So this electrician sorted out more or less all the disasters waiting to happen regarding my electrics in the house. So the
  7. Even when I enter, 27v, 45 and 46a (I do actually think those panels are cabable of doing 48 or very near to it perhaps 47) and 15m distance with 5% voltage drop, the tool still gives me 25mm2 cable required. So two 6mm2 is not adequate? Or what am I missing? Or should I think of it this way.....when I tested 3 panels on their own, I got 25v and 24amps (amps are right but volts are very low). So 6mm2 is adequate for 3 panels? If so, then another 6mm2 cable for the other 3 panels should work?
  8. according to this using 31v, 48amp, 15m length both ways (30m total) and 3% voltage drop, I need 50mm2? so even 12mm2 is hopelessly inadequate?
  9. actually was thinking the same thing. but i would really prefer a single cable as my OCD would bug the hell out of me with 4 cables where there should be only 2.
  10. pictures attached. battery cable is 25mm2 and solar panel cable definitely 6mm2 (picture i know isn't too clear, but i could make out its a 6)
  11. with all due respect, i never said that. i said its about as thick as 8 gauge car audio cable which is more than adequate for a 4 channel amplifer drawing 20-40 amps at 12v. speaker cable is between 10-14 gauge.
  12. worst part is, as i am having this conversation with the forum, im sharing all these facts with the installer, and am getting the "but these are the same cables we install on all our installations" story and basically no willingness to take responsibility for the massive oversight/screw up!
  13. so more or less the size of the current battery cable?
  14. I think we are talking past each other here.
  15. Chart in this thread is blurry but is what you want, no? Here
