  1. Say i have 5kw inverter with Voc of 145v and a 5kw with a Voc of 450v. What will the advantages/dis- be between the 2.
  2. Hi, i want to run my CC PI 5v from my 48v battery, load shedding during the night also creat occasional darkness in the inverter room. I thus also want to use a 12v led. Are there any off the shelf 48v to 12v dc, device's available or does someone have a cct to build one. I already have a 12v to 5v device.
  3. Can one add a pylontech 5000 to a pylontech 3000 ? Some people 'suppliers' said no.
  4. Who used one of these starters on their fridges / aircons? Did it work? Where can I buy one? The reason why I asked , i want to use it on my fridges to reduce the inrush current during the night. My 4 fridges kicks in at the same time during the night, which trickers my inverter to change over to utilitiy, which increases my bill.
  5. I have 1 string of 300w, 2 of 310w and 1 of 395W. Thus the voltages per string is with in specs. Now how can I reduce my 400w eskom power. Can I connect 3 more pv's?
  6. Somebody mentioned in the 8K Sunsynk post, an 8K Axpert. Does anybody have an experience on the 8K Axpert? Reliability ect. I have an 5K one for 5 years now and it's very reliabil.
  7. I assume that your house wiring problem was a common neutral and when you split it the problem was solved?
  8. I assume you have 10 panels in series per string ? If that's the case, I see a problem! However I could be wrong and the experts can correct me. Your Sunsync specs states Max solar voltage (VOC) is 370v. If you connect 10 Pv's in series, with VOC of 45.5v, then your input will be or 455v. This could fry your inverter.
  9. Now that you mentioned it , I never measured the voltage. I just added the voltages from the specs of the Pv's, in my argument. I only looked at the wats, which increased, from from under 2kw to a max of about 2k8W. My array also have a mixture of 300w to 395W pv's. Over the last 3 to 4 years I increased my system with either battery or pv's, courtesy of the tax returns. Each time I bought the pv's that was on special, irregardless of the Wats. This didn't bothers me because I knew that I'm going to revert back to the lowest voltage However I deducted from your reasoning that I'm at my max . Now, how am I going to solve the problem of the 400kw eskom bill? Must I change the inverter to a bigger one, go parallel or wat?
  10. The reason why I want to add 3 pv's is eskom still takes 400kw and the sun pays 400kw. Now you gave me 2 answers. 1st I assumed you said yes for 3 more, then you said I must do 2s6p? Can I add 1 2s to make it 2s7p? I had it 2s4p when I change it to 3s3p , this configuration, gave me a better performance. I then added another 3s to make it 3s4p which gave me a bigger saving. I have 9k4w pylontech battery setup. When the finance is ready, I want to add another 3k5 battery. Thnks. for your knowledge so far.
  11. I have a similar problem. y. Hi, I have 12 300w pv's on a 5k/4k axpert. 3S4P. I want to add 3 series pv's in parallel. I'm afraid that I'm going to fry the inverter? The axpert spec's are 4kw max and VOC is 145v. DC input current is 93A and charge current is 60A. The pv's series voltage is 136.5v and parallel sc amps is 37.6 A. If I add another string the amps will increase to 47A. Do I use the input current 93A as parameter? Can I do this.
  12. How does standby alter the workings of a batt?
  13. the terible triplet (dont knowhow to bringup your name) 25kw is nogabile. As you said its difficult to calculate and I dont understand the calculations and its also difficult to express myself. Thats why I asked the experts. I just want a ball park figure to see if I can afford it. At this stage there is no Eskom power and no house yet. So this will be new installation from scratch. I want to see if I can aVoid to pay ESKOM upfront to provide the electr. to the farm.
  14. well if i cut the sunpart backup out what wil i need? may by backup generator. like how many pvs, Li_ion batteries and inverter
  15. I Have a pylontech us 2000 batt. I got a quote from a Comp. for a Narada Li_ion for about R10k can i just couple it to my 5k Axpert with the pylon?
  16. I recently came apon youtubes with supercaps as batteries for solarpower. Has anybody on this forum use them and perhaps where can one buy it.? Whats the pros and cons? can we use with a Li_ion battery?
  17. jislaaik this is very mind boggeling. My monthly consump. is 750kwh 25kwh/day. with all the addons what do I need to run off grid say 2 days with out sun worst case. would appreciate very mutch. I see 1 firm talks about base line of 1.3 kw, what does that mean.
  18. dont worry about the pv and my excisting setup. i want to know which inverter to use WITHOUT batteries please.
  19. I have solar power for my house and dont want to pay for extra batt.
  20. Hi iam an old member. I am looking for a inverter without batters say 3kw to drive a pool pump. my jaccusie has a seperate power feed with its own DB board from my house. I want to drive the pump from its own inverter and PVS but with no batteries. Any suggestions
  21. I am busy installing my rtc 5kva and I misplaced my software cd. I cant find any software downloads on the net. Is there somebody that could please email me a copy of the cd. E address. [email protected] I also have some problems with my db. Can I dril holes into the side of the board for the out/in mains to the inverter.
  22. Plonkster did you dril holes into the existing DB to feed the new DB. Elaborate please
  23. Jaws how did you wire the surface mount db. Did you take out all the old trip switches and were the wires long enough for the new board.
