    This is a suggestion of @Coulomb . The existing capacitors have a life of 2000 hrs . The upgraded capacitors 10000 hrs . I believe a lot of MOSFET and driver breakdowns is caused by faulty capacitors . Coulomb is the electonic brain and I believe .

    Recieved the capacitors and upgraded 1 inverter today . The MOSFETs K100E08N1 is not upgraded . Will do the spare inverter later this week .
  3. Sorry can't help . Courier cost at Mouser R600 for 250 gram . If we beg maybe a electronic expert can disable the alarm .
  4. The SUNON is the wrong fan . Seems they made the hole larger to fit it . The right fan is only 60x60 . The ADDA fan only have 3 wires not 4 like the 5kW . The 2nd photo is a fan from a later version .
  5. @Weasel mine is the same as yours . No fuse
  6. Don't know witch is best . The Geyser wise system have a 7Ah 12 volt back up battery for times when there is no electricity . The pump is rated 7.5 Watt . The battery should last a few hours . On cloudy days the pump does not really work . I have installed flatpanel and EV tubes and instal the non - return valve on the cold water pipe just after the pump . I also install anti shipon loops on hot and cold water pipes . I heard of people battling with pump if not done like this .
  7. Bought from them and had good service . Best to pay at warehouse and collect .Even had a repairs done during guarantee . No problems .
  8. I use the 12 v because it also power some cooling fans . Just keep it within recommended range .
  9. @Amine you must connect a power supply , the dry contact is just a switch . I use a 12 v power supply and a 1A fuse .
  10. I use the contact NC & C to switch a relay . Program 1 is set Sol . Our setup is offgrid . I use program 12 set 50 v to switch the relay off and 13 set to 51v to switch relay on . If you use the NO & C contact you can set 12 to switch on the light and 13 to switch off . Settings 12 and 13 can only adjust in full volts . You can also use program 1 Utility and set on low DC warning .
  11. If you go this way what do you use to control and monitor your batteries . I use ICC with Pylontech . What is the benefits . Does Victron make a 48v inverter only . Only with battery and AC out connection for offgrid application .
  12. No the hour rating is still 2000 hrs on the Jamicon and I can't get specs on the Jainghai . So I try to get hold of United chemical - con 10000hrs . Thanks
  13. The 5000 Watt Mecer produced March 2018 was fitted with CSD19505KCS MOSFETs 80 volt . The capacitors is 2 Jamicon 80 volt 3300 uf and 2 Jainghai CD 294. 80 volt 2200 uf . The capacitors is now 22 mm diameter not 18 mm . Would you still recommend United chemi - con EKZN 800 ELL 182 mm 405 1800 uf 10 000 hrs .Thanks for always sharing your knowledge with us .
