  1. What is your average downtime re load-shedding, 4-5 hrs, how often, every day or once a month ? What is minimum time that you your incubators can stand for with no power? You need the above for accurate calcs to get battery capacity. It looks like you're using about 2kW/hr so for a 5 hr load-shedding time (and no sun) you'll need 12kW battery capacity (80% DoD), 4 X US3000 Pylontechs will give you 14kW @ about R90K (R22k each). If you want to go 10 hrs, just double battery capacity. PV required: In Alexander bay you're getting an average of 5.4kWhr/kWp installed per da
  2. I have both the Goodwe and the Sunsync. Forget about Deye, get the sunsync, it has better support and a better user interface for the same hardware. Goodwe is a very robust machine, but not as finely configurable s the Deye/Sunsync but it does an exceptional job. There is little difference between the 2 inverters otherwise. Goodwe pass through current is 40A, Deye 35...That's about the biggest difference. Goodwe backup max of 4600W, sunsync=5000W (Not really a big deal either) Goodwe talks "nativly" to Pylontech batteries, beautiful. Also, Sunsync has a groun
  3. The "lifespan" is measured in cycles...E.g 6000 cycles at 80% DoD will give you 6000/365 = 16.4 years... BUT at the end of 6000 cycles the battery will only have 80% of its initial charge available for use.. In real life testing, the Pylontechs reach that 80% of initial charge after about 4500 cycles = 12 yrs.
  4. I expect that you will have to get it back into SA and then it will be sent to Segen who will test it and provide a new one of that one is broken...This will probably take a good 2-3 weeks at best, so patience is required. Being in Zim I imagine this will be a real inconvenience.
  5. The Goodwe has a rated 40A pass through current, the sunsync 37A. There's no on-off (switching from one to the other), the hybrid inverters will supply on both sides to their rated capacity. I.e, the goodwe will push 4.6kW on the essential load, from pv and/or/mixture, grid, and 40Ax330V (=W) through the bypass AT THE SAME TIME...When the draw (A) on either of those is exceeded for a period , the inverter will trip, usually on start-up of a motor, hairdryer.. The "5kW" in "5kW Deye" refers to the PV,battery (DC) to AC current conversion capacity, not the total power that can be "car

  7. Sorry, on hold for another buyer.......
  8. New Inverter, never installed, still in original packaging. Project cancelled. Warrant still in place, original invoice will be provided. Comes with WiFi dongle and earth-neutral bonding relay. R20 000. New from supplier will cost R25K. Whatsapp on 084 402 5839 For collection in JHB area.
  9. What size server, how many "U" is required for 4 pylontech batteries?
  10. Well, it depends on what you mean by 2nd hand. You can check how many cycles the battery has done by using the batterymon.exe, just connect to the battery and then check how many cycles the battery has done. You can also check the charge states of the individual cells....Then you can make an informed decision as to whether or not the cells/battery is worth the money. Read here:
  11. Well, as I understand it, you can have as many panels as you like as long as your FEEDBACK to the grid is <= 3.5kW as determined by either hardware (inverter, PV panels) or software, which I think most inverters can do, limit feedback by software... I do believe there were issues in CT initially where it became an issue with the number of panels one had if their capacity was > 3.5kW
  12. Do you actually need 3 phases into what seems like a normal size home? I use 30kWh/day on average and even 40+ when its cold all on 1 phase. You are paying a fortune to have the 3 phases if you do not have a specific requirement for 3 phase power. It would be cheaper to just ditch 2 phases than buying another inverter, panels etc.
  13. I compare my consumption vs pv produced that is reported by the inverter to what usage my elec meter shows for the month. If you assume that battery power used/consumed takes the same amount of pv to recharge then you can ignore the battery usage as well. I find the results to be within 3% of each other...
  14. There is an Australian company that researches a few battery types, checking reliability, lifespan etc. , started in 2016. So far after 3 years, the Pylontechs are the only battery to not have had failures....https://batterytestcentre.com.au/ They have a good BMS as well... Read April 2020 report, Pylontechs still going strong!! "Operational Issues ITP has not experienced any operational issues with the Pylontech battery pack. " "Capacity Fade The full discharge capacity implied by each partial cycle is depicted in Figure 7. The data suggests a SOH of ~85% after ~1,675
