  1. This is indeed an interesting subject. I am now learing of this with an existing Deye install, where the neutrals was joined on the input and output side of the inverter. I have a Goodwe ES unit, but the way I understood NRS097, I installed a brand new earthing point at my house. This point was used for both the solar panels and the inverter. This ground point I join to my neutral on the output of the inverter. So far all working fine and no issues. So, input side of inverter is using council earth and output is using new earth point at my house.
  2. I am sorry, but some of the naming of the options and descriptions does not really make sense to me? Is there a reference document that gives a full description and function of each option?
  3. Attie, why not post a picture like Achmat?
  4. Should the CT not show Zero if everything is working correctly? Perhaps disconnect the battery and the PV and then see what the power flow looks like?
  5. So I have a friend that could not wait to get his Axpert replaced with a Deye unit. Now after a week he calls me in to help. Unit switches off when grid fails. So I went a had a look. Man, what a ballsup... So the "sparky" decided to wire the two Neutral terminal together, thus saving 2m of black wire. When mains fails, the unit still stays on and shows 230V on the output, but measuring shows Zero volts. I suspect the relay card failed? Would this be expensive to replace?
  6. @RikH, at no point did I say you must ground the negative of your PV panels, or you battery for that matter! If you do that, something will blow up or end up killing somebody!!! As @Sammyigt mentioned, all your PV panels needs to be grounded.
  7. As Saint mentioned, you have to enable the Export Power Limit and set the limit to ZERO. If your batteries is not enough to power you through multiple load sheddings, you either have to add more units, or limit the consumption during loadshedding, or increase the DOD for on-grid. In general mode the unit will not charge from mains, as that would be wasting money. Regarding the MPPT, 580V is the max for each string, not the total voltage, so you should be fine there.
  8. Hi Paul99. Welcome to the forum. Yes, rather run 2 completely separate strings. Each string can be configured differently. Say you have your original string of 10 x 400W. Keep that one as is. Connect your new panels onto the 2nd string. Both strings would then operate independently. That is why you have 2 MPPT's Regarding your battery settings, please use the PV Master APP to configure your system correctly. You should be in General mode. Further you have DOD (on-grid) and (off-grid). Here you can now configure the unit to work great. Say 50% for on-grid discharge and 89% for off-grid. Now under normal conditions your batteries will only discharge to 50% and then you still have 39% left for Load Shedding :)
  9. What does your set-up look like on the battery configuration? You have 2 x US2000 selected? Do you have your communication cable correctly connected? Do you have the dip switches configured correctly? Both batteries should be on Default. I have the US3000 units and mine goes up to 88%. They stay there for some time while amps is still flowing in. Then suddenly they would jump form 88% to 100% in a single step.
  10. Hi, Had my Goodwe GW5048D-ES running now for some years with 6.5kw of PV and 450AH of Lead Acid battery backup. End of last year changed to 4 x Pylontech US3000 as the old batteries was dead. To enable the Pylontech to work correctly, I had to update the firmware to 1151508. Only now I start to notice there is a 4.6kw limitation on the PV side since the upgrade. I used to get over 5.5 kw on some days. Anybody else have similar issues?
  11. Got the same question! Was hoping one could just add the extra 2 units and the BMS should take care of it?
  12. Hi, As of late I seem to be missing huge chunks of data on SEMS portal. I connect via WiFi fine to the inverter, so it is not the Wi-fi. I connect to my CCTV fine when away from home, so my internet at home also looks fine. All I can think of is that with our slow international speed, some data gets "lost"? Anybody else have the same problem? Thanks.
  13. With that amount of PV your battery should not discharge during the day!!! How is you PV panels connected to the inverter? All 17 in a single string, or two strings of 8 and 9?
  14. As stated above; R11/kg for collection. R11.50/kg when you drop off.
  15. I have phoned all the guys mentioned above, and they all willing to collect, so no issue there, thanks!!!
