  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 could possibly be some fluctuations in the GRID AC supply specs that the inverter flagged as out of range? Thanks for the time responding. J
  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 anyone will be able to confirm that the this unit would not fulfill the requirement of an ANTI-ISLANDING device. And on the point of tripping the pre-paid meter. I am lead to believe that on my meter, the feature to shut down on reverse power detection, is disabled. I think, if legislation requires a device to prevent REVERSE POWER FLOW, then at +-R2000, this unit should fulfill the requirement. The way I understand this issue, there are 2 clear terminologies that are used? REVERSE POWER FLOW DETECTION, and ANTI-ISLANDING. Reverse power flow detection/prevention, should react to prevent the electricity meter from seeing this as an attack, and Anti-Islanding is isolation from the grid, to protect maintenance workers from electrocution? Lets see some opinions?
  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 and sensitivity are adjustable, and I intend fiddling with these somewhere down the line. I also increased the size of the enclosure, giving me more space for the heavier cabling. I also left the 50amp contactor on the rail, should it be required later.
  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 structure etc etc etc. I would add at least a few thousand rand more? 3,7kw(76 Ahour) SOLAR MD, I can purchase for about R30k, and get at the very least twice the life span. The warrantee alone, is almost twice the expected life of the gels?
  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? I feel strongly, that if they want to regulate my ground water consumption, FIRST they must acknowledge the fact that I have the resource? Until date, all requests to register the well-point/borehole have been met with confusion and outright ignored? Even in COCT, my well-point in Brackenfell the registration process has never gone further than the application to register. They made an effort to visit the premises, to ascertain why the consumption had decreased from 20Kilo-litres/month to under 500litres, but the registration has simply never been processed. I also do not want to completely disconnect, as should the need arise, the council supply of water and electricity, can offer a degree of comfort and assurance, that I have some kind of alternative.
  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 pipe. Now we the same basic charge on the amp rating of your electrical supply. And fines for tanks already installed, and metering with allocation to the ground water. Damned if do! Damned if you dont!
  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 such? Or seen this unit in a test application, where the function can be tested? This appears to be another one of those topics, where in-depth technical information seems hard to find? Although there are a few units on offer being sold as REVERSE POWER FLOW PROTECTION or ANTI-ISLANDING devices, the technical information seems a little unclear, to me at least? Maybe my lack of experience in this field is my downfall here?
