  1. On my Infinisolar it stipulated its own seperate neutral. Not to be shared with the incoming connection. It never had a leak from neutral to earth. I suppose its got to do with the design - I know some makes earth their own neutrals. Anyhow, the circuit after the inverter must trip its own earth leakage.
  2. Search “Sunsynk” and you’ll find a similiar problem and the posted solution. On the Sunsynk there is a special connection for a relay.
  3. Please bear in mind that an inverter generates power that can kill. So test your plugs with an earth leakage tester. A 16a plug can only carry 3,5kw +- Like all overloaded electric devices an inverter can fail in a spectacular fashion. If you can push it to beyond its design output it indicates that your overload mcb connecting it to the db is an incorrect size. For my 4kw Infinisolar it was only 20a - I kept it like that with my Sunsynk 8kw as it manages my low amp db. For a 3kw device it should be 15amp.
  4. Dc surge suppression goes to pv panels. The inverter & battery earth wires go to the db earth. The main isolator must be two poles for neutral and live.
  5. “No need to separate essential and non essential loads.” Dependant on your model and amps you’ll draw. I had the 4kw hybrid replaced now with a 8kw Sunsynk) and it would go to 5kw amps overload with mains backup. The Infinisolar performed faultlessly for three years as a backup on a low amp db setup m It is better (my opinion) to look at the amps you pull from the db. I had to create its own neutral to earth connection on its delivery side when I installed it. This gave me lots of problems as my house is old with connections going everywhere and I had to sort all the neutrals
  6. Get yourself an earth leakage tester and do the tests after all the wiring is completed. It is interesting to see at what ma the rcd trips. It will work if the second one has its own earth (tip from Aus).
  7. You realise you’ve bought a 3 phase transfer switch.What do you need it for? Inside the box there are clear instructions. I’ve installed three Hager transfer switches now and it was easy.
  8. Moet nie te gou praat nie - die Vaaldam begin nou eers oorloop op 101% vol.
  9. Welcome to my world Get a clampmeter (not too cheap but they also function as a multimeter) and read the ma between neutral and earth. Remember they all add up. I’ve a fancy borehole controller that gives a high 30ma reading. On its own it can cause a trip when it comes on - requests to the local factory on this issue go unheeded. Surge protectors also add to this load. And the current wet weather will help as well to show up poor insulation of cable cuts and connectors. Sometimes my rcd also trips when the power comes back. If you have several rcds in sub db’s (seems you
  10. I must say I’ll pay Eskom gladly their 0,78c per kwhr which they charge the local robbers. Plus my account will always be up to date. Promise ... I don’t feel under obligation to pay for the caders..
  11. Disagree totally. If they can charge me I must be able to penalise them for loadshedding and power failures. I get supplied by the munisipality who owes them R3b btw. When last could they meet their demand 100% They keep their lips flapping - thats all. No discussions of any kind will save their (and the ainncee) asses.
  12. I remember the Richardts Bay aluminium smelter saga from a few years ago where the consumers were subsidising them due to a very generous contract Eskom had with them. I don’t know what the outcome of that was but my logic tells me that scenarios like that one continues to this day. We often see reports that government departments have not been settling their accounts. Combine that with fraud and I have no sympathy for them. We know their (extremely well renumerated) labour is far more than required. They also tried to get rid of their housing subsidy book some years ago. Rumour h
  13. How far did you open it? 90 degrees?
