  1. While working for company Nigel Diesel many years ago a John Deere tractor was brought in . The dieselpump and injectors was reconditioned and the enjin was overhauled by another company but still no power . Connected it to the Dyno to check hp . First the basic test was done . Fuel , water , oil ect . Result aircleaner completly block . Have you ever seen a angry farmer
  2. I use the Dry contact signal to switch high load of when it is cloudy . Do not want to use the batteries . Don't have utility .
  3. We use a 5kw Axpert on a off grid installation . It does have some value for us . Did not use much power after 10:00 today
  4. Like Coulomb stated above it is not wise to withdraw more than 20% of the power of all lead acid battery . Withdrawing 200 watt for 7 hours from a 12v 200 ah battery is not good practice . Your question is why does the battery last longer on the Trailboss inverter . The only way to find out is to get a meter to find out what power is really used . Have you measured the amps taken from the battery . This can be done using a clamp meter on the battery cable or Victron has a battery management system that can do this very good but the cost is about R2200 . You can also use a digital power monitor that works with a shunt PZEM -051 . The cost is less about R280 . This will give you an better idea of the power ( kWh ) you take out of the battery . If the power used is still a lot more on the Axpert there is some fault with your Axpert or installation . The PZEM can also measure the amount of power going into the battery when charging . Keep in mind that there are losses when charging . The best to do now is to keep the batteries fully charged to limit any more damage to your batteries . Get a specification sheet of the batteries so you know what is good practice with them .
  5. Used a Arduino with a light sensor to control the switching of water pump . Cant that be used to determine the amount of light available .
  6. Yes that is true . The connecters of the Sonoff basic and POW 2 can be improved . Very easy to make a bad connection . I still like them but triple check the connections .
  7. Using a 10amp Sonoff on a 750 w swimming pool pump with startup current off 8 amp for more than a year and so far no problems .
  8. @Adri Trojan have a very good website with all the info you need . Charging , equalisation , maintenance , specifications , storage and training videos . Trojan . com will be all you need
  9. New batteries can be shipped dry . Then discharging is no problem .
  10. Left Axpert switched on Right Axpert switched off no load . When the Axpert is switched of the discharge is very little . Hope this helps you .
  11. What size battery is this . The 5 kW Mercer use 600 to 700 watts from 6pm to 6am if it is switched on with no load .
  12. The more efficient charging of lithium batteries makes extra energy available . Boiling a kettle or 2 is hardly noticed .
  13. PiShop Vereniging do have stock of some Sonoff switches . Check their web site , availability can be checked
  14. Thanks , have not used any of these Sonoff wall switches .
  15. Because of excess electricity we installed a 2 plate Elba countertop hob . With these electric plates the higher settings use more watts .The large 2000w plate is 2000 w on setting 6 , 1100w on setting 5 . LP gas reduce by 60 %
  16. Don't know about EU/UK/US tipes . All the Sonoff switches I bought local and import have a voltage input range 90 - 100 v to 240 - 250 v AC and RF433 MHz .
  17. For the pool I also use Sonoff RF . Remote is handy in my pocket to switch for what ever reason . Clouds , backwash ect . I can see if it is cloudy on the CCTV then switch the pump off using Wi-Fi if not at home .
  18. @Tsa I use Sonoff RF switches with the Sonoff remote . For the lights the Sonoff is installed inline with the curcuitbreaker in the db. The lights we want on is switched on at the switch . The pool Sonoff is also in the db . The Sonoff timer is set for times when needed . Also a panic alarm connected with Sonoff remote The RF is quick and always available when in range . Our WiFi sometimes needs to reconnect to Sonoff but is also handy .
  19. Falken I see you do a lot more cycles than what I do in the same period . Do we know what influence of DOD have on Total AH over time . Thanks
  20. Royals are not deep cycle batteries . What is the real state of these batteries ? . If you can get the date code on the top of the batteries we can determine how old they are . Then have a load test done on them to see how many is still useable . I would not cycle them more than 15% DOD which is about 1.4kwh avialable. If you take more out of them they won't last . I will suggest if you want to use the batteries , buy a 1000 watt Axpert and use it as a UPS . As long as you keep it offgrid it is legal . I will not buy storage box for the batteries they are sealed and kept clean easy . Don't run the battery voltage lower than 24.6 v on the inverter display (12.3 v per battery ) and you can get some service out off them . You can then deside if you want to ad panels later .
  21. @Valken My 3 x 3000 Pylontech batteries was installed 8 August 2019 and have done 87 cycles . It has not lost any capacity so far . When fully charged it shows AH remaining 221.1
  22. I also use Lead Crystal batteries . Setting 26 - 58v Setting 27 - 55v The charging specs on the batteries for my storing temperature . Lead Crystal
  23. @ Rusti. The recommended charging rate is 37 amps . The inverter can only be set in values of 10 . Setting no 2 maximum charging solar plus grid set at 30 amp . Setting no 11 maximum charging for grid set at 30 amp . Battery should charge from grid in about 2 hours .
  24. If have seen this happen on a 1000 watt inverter running a small load , when the freezer starts it shuts down .
  25. @GVC I like what you are doing . Can you please tell me which version of Python you used I've downloaded version 3.2.3 but then I get an error No module named serial. I would appreciate your assistance, thanks Marlene Louw
