  1. v series inverter running self consumption 20A inverter supply 63A Eskom supply breaker use max 6.5 kw 0 DC battery demand unless eishkom off 10a charge from inverter 35 A PV max current 0A export but can do 1.2 kw cheers
  2. just an idea might fit your scenario since you want grid tied high voltage panels like this https://www.sustainable.co.za/renewsys-deserv-260w-high-voltage-solar-panel.html there are others out there as well grid tied likes high voltage check it out cheers
  3. great reading guys just a quick question there seems to be that 2 fuses are mentioned a lot why the chances of the two fuses blowing at the same time are minimal are there scenarios of sometimes the positive leg fuse verses neg leg fuse ? just curious cheers
  4. thanks guys @Jaco de Jongh there wont be any icc but I love the battery monitor idea cheers
  5. thanks guys but no lipo no pylons as I believe they need to talk to the inverter remember I have a pwm cc to consider looking at 4 x 200ah in series or something trying to get to the 20 k range for complete set also want a victron battery monitor to switch back to Eskom any ideas on that would be appreciated cheers
  6. have a guy that needs new batteries at present he has 8 100 ah bats 4s 2p being a old 48v system with about 3.4 kw panels and 2 pwm charge controllers I told him to go with 4 series 12v 200 ah bats to simplify things Now the big questions battery recommendations excl lipo I have been impressed with Omni power in the general range of 2500 cycle lives Trojans are good but seem to be in the 1750 cycle life range or maybe I'm looking at it wrong cheers all
  7. hi there always loved this idea but where's the 50 v come from what mods do you do cheers
  8. at the point where you show the two meters whats the load on the inverter does it match the output of the out meter
  9. HI there what geyser do you have and how many people in the house cheers
  10. sounds like you have a floating earth on your old panels are you sure the old panels are actually earthed and to where did you have shoes on when you got the tingly feeling do you still get shocked if panels are not connected to the inverter is your inverter earthed
  11. I have a v series which I run in self consumption mode does the goodwe not have that or at least a swap back to Eskom maybe as batteries are expensive thanks for the great info interesting reading cheers
  12. hi guys am I reading this right at about 8ish your batteries are at about 25% soc . does that mean 75 % depth of discharge ? what are the cable sizes from the panels . thin bad thick is good just asking cheers
  13. Ok guys the spare panel and test was just my way of explaining how I got the idea sorry I didn't make myself clear, my bad my big picture or question is would it be possible to use this idea on a bigger scale like connecting to a house that has a larger solar set up ? first of all could it work ? and if so, what do we need to do it so on and so forth so my theory is that when the batteries are full or the load is small then all excess energy goes to heating (geyser) and is not being wasted like having an inline dump load my thoughts go along the
  14. Bare with me for a moment and you might see something interesting so I have a spare 37 voc 250 w panel and was wondering if I could charge a 12v battery with it but im concerned that the controller could not accept 37 v or at least 31 while starting ( yes it pulls the panel down to 12v while charging but still concerned) so I have a 110v 1500w geyser element lying around which I placed in line with the solar panel this caused a voltdrop over the element of 18v which meant that the controller now also got about 18 v which it should be quite happy with ( 18v x
  15. I also have the v series and think its the best thing since chappies you can have the grid tie function on or off I run mine in what I believe is called self consumption mode meaning ie it subsidises the solar with Eskom or whatever solar cannot supply it takes Eskom for the rest my main reason for buying this unit was not to cycle the batteries today at 12 I see 10 -40 w at the supply to the inverter, this fluctuates as the load /sun does esp cloudy days im not sure but this could be importing or exporting as the load/sun fluctuates my concern is tha
