  1. Deye appears to be the original manufacturer and all others are branded versions of the Deye with possibly different firmware as well.
  2. @ThatGuy what do you buy that's Made in (the EU)? I wonder, I think most everything these days is made in the far east.
  3. Well @Smarti84, Brexit or not, Sunsynk (http://www.sunsynk.org/) is based in Hong Kong/China, I'd say contact Keith and see what he says.
  4. Sunsynk and if that's not available the Deye unit (Sunsynk is Deye rebranded...) would get my vote... been running a 5kW Sunsynk since end June last year.
  5. I would have suggested a Sunsynk 8kW or 2 Sunsynk 5kW units... don't know the Axpert, but the Narada spec sheet says the battery has RS232 and 2 X RS485 ports, so , presumably you'd plug the RS485 from the 1st battery into the 1st inverter and the 2nd battery's RS485 into the 1st battery, not sure about how the power is paralleled up between the inverters, presumably one would need to also plug the RS485 from the 2nd battery into the 2nd inverter, but which inverter charges both batteries? etc. that setup could get interesting. Also I'm assuming the inverters have RS485 for BMS connection to t
  6. So, looking at the piccies, both inverters are trying to charge//discharge the batteries, but no actual DMS comms between batteries and inverters exist... that seems dumb to me, also, if you *actually* need 10kW peak power, I'd say that you should probably have 2 batteries per inverter and no DC interconnect between the inverters, but certainly BMS's from the batteries talking to the inverters. Based on the last piccie, is the left hand battery claiming 0% SOC? its got the shortest cable and would probably be required to deliver more of the power...
  7. Powering from DC I'd recommend the following:150+66 Avoid lead acid, else you will have to come up with a "BMS" for these to ensure you only draw a certain %age out of the battery, lets say 20% and have a decent charging circuit that won't get the battery into gassing territory on re-charge to enable a reasonable life out of these I recommend a LiFePO4 pack per application with BMS and charging circuit for the the battery pack, again limited discharge and ideally also charge, if you can calculate your need per consumer item/battery pack and keep the charge to 90% max and on the botto
  8. Not sure, but could it be that by the time you switch to SBU the battery has been charged and this would have generated some heat? Does the temperature stay high if you were to leave it in SUB mode?
  9. Command line stuff, more likely I would think, @Peet Welthagen use ssh from the terminal window on your Mac to log in and get a shell prompt from the Pi. I'd imagine that ICC should be accessible, once configured, via a web browser/Safari from your Mac.
  10. Forgot to add the obvious, Eksdom ain't getting any cheaper, it may still be the cheapest battery in 5 years time, but unlikely to be the most reliable, but that, I guess, depends on how you treat batteries, chemical or otherwise you may use as replacement for Eksdom.
  11. I doubt it, since that would depend... what E-Skom/Municipal rates are you paying etc. also what your actual power needs are, which would determine how large a setup you'd require etc. What is 100% true right now, is that E-Skom is the cheapest battery, but that's total BS, since when that battery is dead (rollling thingymajigs) then the cost doesn't really matter, after all the cheapest car that doesn't run is just a pile of scrap metal with more value than Eksdom when they're down. So, going solar/wind/wave/whatever else energy is not necessarily for everyone. Solar is the lea
  12. Ok, lets re-look at this... the problem with my suggestion would be that you'd have grid coming in to earth leakage and then inverter, output of inverter feeding the rest of the house which would have to be decoupled from the input/grid connection, but not fed by way of earth leakage. This is problematic, so yes, what you want is to leave the loads where they are and use the current transformer to prevent the feed to the grid, but allow feed to your load devices on the input side of the inverter.
  13. That way of connecting it would be fine, if you're trying to grid feed as well, I guess, if you do not want to feed back to the grid you should connect your load to the output and not enable grid feed.
  14. Somewhere around St Helena Baai, that Eksdom are doing quoting should pretty much indicate that Cape Town does not cover this far out of town...
  15. Until the grid disappears.... Also your option is only financially viable if you're already on the grid and the energy provider will allow feed in. I have an acquaintance who's about to build somewhere outside the CT municipal area, along the west coast and he was talking about somewhere around 60 to 80kR for Eksdom to put in a prepaid meter and power line, there is no power on his premises at this stage, I suggested solar + hybrid inverter + wind turbine + some battery capacity and when all is smeared with what hit the fan a little generator to add some 'lectrons to the batteries.
