  1. Hi Youda, Sorry to hear of the personal issues? I hope you can work it all out? I changed the WIDE AC INPUT RANGE to ON , which seems to reduce this warning message frequency. I also contacted the inverter supplier for technical advice? They suggested changing GENERATOR AS AC SOURCE to ON?? Cant see how this could help, but I havent had the warning message since?? I must mention, that I am located in a small residential area, where there are a few large industrial consumers nearby. We tend to have large fluctuations in the pressure on our water supply, and I imagine, there
  2. Yesterday, I had warning message #07 (AC INPUT ISLAND) on my INFINISOLAR 5kw inverter? According to the user manual, this warning event refers to ISLAND DETECT, and the description says ISLAND OPERATION IS DETECTED? No further information is provided? No recommended action is given either? Has anyone had this warning message before? If so, can someone shed a little more light on this? The inverter is set to NOT ALLOW feed into the grid, and an ANTI-ISLANDING protection device is installed. This unit has not detected and REVERSE POWERFLOW?
  3. Thanks. The bootlaces do make a neat build. You should see my wire markings?LOL. Wrap-around thermal labels, on all the wires. My thinking here was, should I need to move something from Non-essential to Essential load, I would need to move the neutral and earth too, as each is seperated. This way, I don't need to search for wires. To be quite honest, I'm not concerned over a momentary feed-in or spike. What I want, is should the grid go down for any reason, I want the disconnection to be made. Also, I imagine, should any compliance be required later, I seriously doubt that any
  4. Just an update. Installed the REVERSE POWERFLOW PROTECTION RELAY, Rhomberg SP510, and an 80Amp 230vac contactor. The original picture shows a 50amp 4-pole contactor, but I had an issue getting the 10mm² cables into the terminals, so I increased the amp rating to the 80Amp version, and instead of doubling the the contacts, just used the 3-pole version. I also purchased a CT closer to the rated 63amp supply. Tested the unit by inverting the CT, and it definitely trips out the contactor. I'm sure this will suit my need, for an anti-islanding device, should this need arise. The delays an
  5. Hi again Youda, Finally received my infinisolar inverter, and struggling to get my head around all the setting values in SOLARPOWER? Is there anyway you could post screenshots of the settings you are running? This would be of great help, as a comparison tool? Thanks.
  6. I'm trying to get my head around the capacity of battery storage i would need. I have got info from SOLAR MD, that the 3,7kw unit is equivalent to 72 Ahour @52v. Practically, I think this will not be enough for my requirements, and I should therefore be installing the larger 7,4kw unit. Doing a very basic cost comparison between gel acid and lithium, looks as follows..... 200 amp hour gel acid x4 (12vdcx4=48vdc) @R4600 =R18400. Factor in the DOD @50% gives you 100 amp hour for around R20 000? Some shopping around may yield some discounts. Cables, cable accessories, fuses, frame
  7. Cool thx. Your usage looks pretty similar to mine, in summer.... lol.
  8. Hi Nigel, My LANDIS+GYR is a SABRE ED. Interestingly, TOKENS are mentioned in this thread too? In this PDF, there is information listing tokens? Not quite ready to fiddle with the meter yet? Maybe someone, who has had these tripping issues, can share the process of resting or restoring the meter? How the process works? Maybe being familiar with this process, can help us, should we find ourselves in this situation? Thanks, User Guide Sabre Mk5 Rev 0.0.pdf
  9. Awesome information, Phil. Thank you for taking the time to share this information with us. I do have the unit, and have already built the basic setup, and will be installing it next weekend. If I have any new information, I will share it on this thread.
  10. One must also look carefully at the legislation, and take into account the ONLY larger commercial users are given allocations (as I understand it?) and I'm not sure if physical metering is actually performed in some way? Residential use requires only registration, which is free. Never actually completed, but there isn't any cost attached. My borehole/well-point delivers well over 1250/hour and can potentially deliver vast amounts of water over a period of time. I am consuming about 500-600 litres/day AVERAGE, and the local council showed almost no interest in my system what so ever?
  11. Hi Mstott, Can you share more information on your system, and your consumption? I am trying get a feel for the capacity of these units, and which kw size unit will best suit my needs? Thanks.
  12. I have been informed by SOLARMD, that the logger unit mentioned, does not communicate with the INFINISOLAR inverter? Can anyone offer more info on this?
  13. I suppose one could argue, that these water storage tanks require a foundation or footing, and that planning permission is required. Therefore, a fine for non-compliance is a nice way to make some additional revenue? CoCT begged every resident to reduce water consumption to 50 liters/day, and when those that paid the municipal bill, generating the required cash-flow to finance the indigent, low income, and non-paying users, found alternative solutions, and effectively went "off-grid", this cash-flow dried up. As a result, the basic charge was introduced, based on your mains water supply p
  14. Hi Jaco, My main goal is to try to prevent the prepaid meter from tripping, and resulting in issues with the local ESKOM croud if such an event occurred? I agree that disconnecting the AC GRID supply is not a good idea, I hope to not have this happen? Hopefully, and I cant confirm how this unit will react, I am able to prevent reverse power flow in a worst case scenario only? I am also convinced, that this issue will arise again in the future, as local legislation catches up? Has anyone actual had a ZIEHL RELAY prevent reverse power flow where the reaction has been witnessed as
  15. Curious to know what the monitoring system/software is, and what hardware is in use? Thanks.
  16. Even the ZIEHL is rated at 0,05 seconds, which is 50ms by my calculations, and my maths is terrible, lol. I think the only wat, to prevent the prepaid meter from tripping, is to have a meter installed that wont trip, and this is a pile I am not prepared to step in?
  17. I am fully aware of the response time, and have looked at other options too. My main goal is to disconnect from the grid, in the event of a power failure or load shedding. I tried contacting the manufacturer of the prepaid meter, but just got a generic response. The SP510 appears to be the only device available which is designed specifically for this function? I havent been able to find anything else, which clearly states the function of REVERSE FLOW MONITORING? Maybe someone can advise on a faster alternative. An electrical engineer I spoke to, seemed unfamiliar the the terminology,
  18. Decided to try using a RHOMBERG SP510 to monitor RPF, and hopefully prevent the LANDIS+GYR prepaid meter from tripping. A 100A ct will be fitted to the live grid supply cable. The SP510, will control a 40A 4-pole N/O mechanical contactor, where my incoming grid load will be bridged across 2 contacts each. I know electrical engineering design, requires double contacts, decreasing the failure factor. As I am not in the COCT area, and don't have any local requirements to adhere too, I wanted to see how effective this will be. I do not intend exporting to the grid, so just wanted to add an ex
  19. And.... You would be able to generate most of your required energy during normal working hours. If you are operational 24 hours, you would be reducing your electrical bill by at least 30%? Without the batteries of course, a major cost component of the capital investment.
  20. It is also against the law in SA, to grow crops like canola, solely for fuel production. Alternative fuels manufactured from plant based materials, may only utilize WASTE products?
  21. As part of international trade agreements, waste oils are exported, at the $price making it nicely profitable, when local bio diesel producers cannot get their hands on the raw materials needed to produce a cost effective product. Bio diesel production costs are also unaffected by crude oil prices and international exchange rate, making it very difficult to compete in a market where the GREEN factor is ignored in favor of price. I purchase huge quantities of waste sunflower oil, from a bio diesel manufacturer, who finds it more lucrative to sell the raw material, than to produce bi
  22. On average, 600-700kg of waste plastic(high grade, clean waste) may yield around 500 litres of wax based paraffin, of which 20-25% is utilized in the pyrolysis process. The emissions and off-gasses, resulting from this process, will be almost impossible to pass local legislation or environmental by-laws.
  23. This plastic recycling pyrolysis, is not as good as it promises. The end result, is a parrafin wax type based fuel, that stinks to high heaven. I have done extensive experimentation in this field, and this only becomes feasible on a massive scale. Some of the huge industry players, who have all but taken over the raw material market required, have abondoned most of the pyrolysis as uneconomical. I manufacture an industrial heating fuel, using waste vegetable oils, and have yet to see a pyrolysis plant run and actually deliver a cost effective product that is usable or marketable.
