    There are many..............................but I seriously just dont have the energy anymore.........

  1. Hi Coulomb. No, I am pretty certain it is a active device. I absolutely see what you are saying, and that being the case, yes ........what is the point? So the only real gains to be had would be improving your smaller / existing inverters surge handling ability to match that of a larger unit but at less of a cost of a larger unit or inverter upgrade. Device label indicates 100A, which at this time I will assume to be a peak/surge rating judging by the small gauge of wiring I see in one of the images. I will get back with more info, thanks Coulomb.
  2. True, it would add to cost space and weight. The additional PFC would be incorporated on the output though in the sense that it is connected to the loads , correcting PF so that the Inverter itself sees primarily resistive load. I dont know how susceptible inverts are to tripping or shutting down when encountering start-up currents , I absolutely stand to be corrected here but sounds though it could be quite a common issue , which if curbed may allow for substantial increase in base load. That all said assuming what I am suggesting does have merit in a theoretical sense.....
  3. Coulomb, I appreciate your inputs thank you very much. Considering the numbers you provided , being able to maintain unity PF should yield considerable reduction in peak current seen by the inverter...... Certainly seems like an avenue to be explored. Does beg the question though.......if there is going to be such a benefit in the ability to curb peak start-up currents improving reliability and operation....why are inverter manufacturers not incorporating PFC's on their outputs?
  4. Hi Guys and Girls, Hope all is well. A question I have after having a discussion about a system I need to install. I have been advised to install , what essentially is a PFC between the inverter output and the loads. ( Device in question is a Turner Morris High Efficient Energy Saver. I would be interested to hear if anybody has any experience with these ........or has any alternate suggestions. Essentially a PFC so connected to households running older fridges, AC's, pumps , flourescent lights etc, I can see that there would be savings to be had, I will be looking into one of these
  5. Thanks @Gerlach. I have taken a look at that BMS........assuming that is the that the Ant BMS? I would be very keen to hear how it works for you. The Orion, Batrium and Chargery BMS's look to be very complete in their development, a finished product with decent functionality (speculation ) with everything in Enclosures etc.......................and the price tag to boot unfortunately. My pick would probably be the Batrium, per my understanding a bunch of Longmons and one BMS would allow me to monitor individual cell on all of the 5 parallelled batteries. T
  6. Thank you @Richard Mackay, I will be sure to check out a few of his vids.
  7. Anybody have any experience with the Chargery BMS systems?
  8. @Gerlach Could you please enlighten me as to which brand this would be?
  9. Hi, Thank you Gerlach. Has there been any one product that peaked your interest? There certainly are products out there but I am hoping to also receive some insight into what might be available locally and have some proven track record among the forum members. Later
  10. Hi Mike. I much appreciate your response, thank you very much. The Batrium definitely looks worth considering. So if I had 5 of these 14s batteries (2.5kWh each for arguments sake) operating in parallel, I would need a Watchmon4 and 5 x 14 of the Longmons. That seem accurate ? The approx cost of this would be in the region ~R25K, before Shipping, Duties and Taxes. This is what confuses the hell out of me. The going rate for lithium batteries (admittedly I could do more homework here) seems to be in the region R5k to R10k per kWh. Considering the above, R2k to
  11. Hi Chaps. Hope you are well. Guys,kindly please share some wisdom with me. I have a few NMC Lithium Batteries. Essentially an enclosure and cells, but no management system. Would you be able to recommend a supplier who could help out? They are 28 Cell units, but charge voltage ~56V , I am expecting that the internal configuration though is 14 pairs of 2 paralleled cells. I will need to physically inspect to confirm . This being the case I guess I would need 14s BMS. Also, would I be correct in assuming that in general: Cell balancing and temperature protectio
  12. Thank you very much for the welcome Jaco. In a nut shell what I am hoping for is to install a hybrid system (my understanding of hybrid at least) that has the ability to : Use solar during the day to supplement our AC power usage and charge batteries Have the intelligence to regulate AC output so as to not export power to the grid (For now at least, as I understand with older meters I will be billed for power I export, and I dont know what the current situation is wrt Net Metering ) Use battery backup to supplement solar during low solar conditions but with a priority
  13. Hi all Name is Kassie, ............and I am a repeat offender......... I repeatedly say nasty words and pull out my hair when I think about the state of electricity supply and our monthly bill....... The time has come to take a serious look at, at minimum supplementing Eskom supply with Solar, and I look forward to learning about this stuff. I see that there are many smart and experienced people on the forum who are willing to share their thoughts and experiences, big thumbs up to you all. I hope to be able to make valuable contribution some day too. Till
