  1. thank you - at least it has been done then. I had the ellies as a loadshed emergency but since then have installed axpert and now need a solution out on a plot. Seemed silly to not use the ellies.
  2. Thank you for the supporting email - I now have confidence that the problem can be solved. I have received a PM from Wolfandy and he will assist me without further burdening the group. Yes, load shedding started this week. (Inland - at least here around Johannesburg - we are experiencing the coldest winter in years. I think that is not helping). And the municipalities seem to have lost some of their vigour in dealing with it - in my area (in Johannesburg) the power came on for a few moments and then tripped out again. It is back on this morning. Wolfandy reports the same thing f
  3. Thanks millions. So if you are still feeling 'adventurous' late in the evening (and you have power back), you can even still make these changes tonight Yes I definitely would have tried. Your advice seems spot on. But the sticky point lies in the term "(and you have power back)". After long efforts been determined that a substation in my suburb got overloaded and tripped out. No power yet and no ETA. This is exactly the kind of problem I want to insure against - I need to go into a loadshed with batteries 100% full and sucking up the sun tomorrow morning photon by photon.
  4. I am concerned that without knowing the settings that have been programmed in ICC, ICC might override whatever changes we program directly on the inverter I suspect this is exactly what is happening. OK I will see what I can do to get the computer part sorted. My installer says VNC access to the Pi has been set up but I need to get it form Centurion Solar on Monday. Can we proceed without it - perhaps tomorrow? I am fearful of doing anything right now while in the middle of a loadshed. I must again thank you again for your incredible assistance. Much appreciated. Le
  5. OK thanks for the help so far - i can comment: This is definitely not the way that your system is currently set up. How did it change then? Because it was set up correctly - at least as I understood it because there was no flipping between solar and mains at all. This came about the moment I tested the system. Do you have direct access to your Raspberry PI? Has a VNC access to the Pi been set up (for you)? I will have to ask the installer. He was very good with the electrics but does not understand the Axpert system very well. To date I have not managed to find one who do
  6. What I see on my ICC. I know just enough to be very concerned. What bothers most is that this started after I tested the system. I.o.w. there was some kind of default reversion to a primitive state. Very threatening. I am in your hands now.
  7. Wofandy: Does this mean that you are also running ICC? If yes, can you please post screenshots from your inverter settings tab? I think I am running ICC. I do not know what an inverter settings tab is. I will attach what I can see in next mail. Can you please help us understand your loadshedding / interruption situation? Are we talking about 'normal' Eskom loadshedding of 2.5h? If yes, then I believe there are ways Answer is yes but there is no such thing as "normal". Load shedding may hit 4 hours or the beloved Jhb Council may trip its substation for a week or they may take 24
  8. Update: Introverter: Try and be a bit more specific about what exactly is the concern, the inverter going back/forth/back/forth between eskom/battery? Not staying on Eskom when you put the mains back on? What the best voltage settings are? I do not know whether I should be concerned. I have no idea what is going on but suspect that the batteries are running themselves into the ground at which point either mains or panels kick in as a last resort. This is my main concern - the batteries are powering the load to the full extent of their charge. Let alone if that happens before the lo
  9. OK I am just back from earning my living. I will incorporate all the above and answer. In the middle of a loadshed right now btw. And all seems OK . . . for now. Tx for all the feedback - will do my best to provide answers.
  10. oK the invoice states: AXPERT Hybrid 5000VA Inverter Charger with 4000W MPPT a picture attached. The machine also makes quite a noise at the moment. Sounds like a car being revved. Label attached
  11. Or was the system sitting there after being installed and you for the first time switched off the mains last night? That is the one. The battery reached a voltage set point (programme/menu 12& 13?) where it then stopped using Eskom to power the loads and started using the battery again....the battery voltage started going down and after 20 minutes the inverter started using Eskom to power the loads and charge the batteries... rinse...repeat...rinse...repeat... How I envy your knowledge - this is exactly what appears to be happening. I will post the detail asap so that
  12. that is no problem - it is the batteries that take the strain when you charge and use all the time. I expect 20 years from the panels. The batteries can be 3 months or 8 years depending on use.
  13. I tried to upload pictures but the forum rules block the pictures as too large.
  14. Please somebody help. I have an Axpert 5kva installed with x4 180amp AGM batteries and x6 330watt panels. A Rasberry Pie is attached. The idea is to only use as a UPS. The panels should only charge when mains are off. Ie charge from panels during a load shed or other interruption. In this way everything lasts maximum lifetime. I lose a bit by only using the panels during a time of crisis but so be it. Been operating this way for a while. Then I tested the system by flipping the mains off. All works like a charm. Except last night I noticed the system switching b
  15. As far as I know you are permitted to produce electricity. But that does not mean you may attach a panel to your landlord's roof.
  16. . I am prohibited from using my own alternative energy source while somewhere NERSA allegedly states that everyone should have fair access to it? ...too bad, you should have checked before you signed? No. Assuming that the NERSA provision grants you a right that stems from legislation (in this case the Electricity Regulation Act), then that right takes precedence over the agreement. Unless legislation specifically permits it, parties are not at liberty to contract out of legislative rights. Eg you cannot agree with your employee that he will not go to the CCMA when you dismiss him unfairl
  17. Amen. Perhaps just this rider - sometimes something is not specifically stated but still absolutely clear - called a tacit term. But we dont have to explore that at this stage.
  18. Thanks guys - as usual the help is formidable and deeply appreciated.
  19. Thanks so much. If I may ask more? Can I add a 2nd panel later? Where in Jhb/Pta area can I go to get everything I need to do a self install?
  20. A similar question has been asked but I was unsure about the answer for this trolley. I want to use my Ellies inverter as a UPS only and only feeding an extension cord. It is on a farm and mains is unreliable. So I need to connect it to a 330 watt panel to charge it at times when there is no main supply. Sometimes all day. It can be connected directly to the batteries? 1. Can that be done? 2. If so what do I need to set it up? 3. Can I solar charge the unit while running equipment of it at the same time? (ie mains are down but I am watching TV while the sun is shini
  21. I am a lawyer. Not sure it helps though. And this is not professional advice - just my impressions - on the face of it. The number one question is not related to NERSA. It relates to your rights as a tenant flowing from the rental agreement and/or any other terms you signed on to. If you have the roof above your own shop the question then is whether you may install on it. That question is answered with reference (first) to the written and tacit terms of the lease agreement and any other applicable sign-on terms. If the agreement is silent on the issue then the common law may ap
  22. OK I will try and check. Someone is coming on Wed to install panels so he can perhaps assist me. Tx so much. The batteries are brand new and hardly used. Is it likely just a connections/fuses?
  23. I use a 5kw Axpert. Drawing about 400 watt at any given time and all is fine. BUT when I switch on a small kettle (750 watt) it trips. Out stone cold. I have to switch it off and back on to revive it. Why is this??
