  1. Greetings Jaco, do you still have the Canadian solar panels or can you advise on requirements for a Growatt 3kva 24v.

  2. I am showing you the error in what you said about the MPPT, I am not saying anything about any Hybrids, but to be honest, I did not expect you to understand.
  3. That is not the way Victron operates. I will PM you the details of someone you can contact at Victron, He will sort you out. Victron themselves will not tolerate something like this.
  4. You can of coarse connect it to the output of a 3kva Victron with batteries. The PV inverter wll then take the place of the MPPT in the system , that should be the most effective way of doing it.. Doing it that way, you will even harvest the sun while the grid is off. If the unit is too old, and without Sunspeck, you would need a Carlo to tell the ESS what the PV inverter is generating. (it is needed for control)
  5. That is correct.. although i have seen 10mm used on a 60amp breaker over very short distances. I still prefer the 16mm...
  6. Because this is a monitoring device and not a load, I use a 2.5mm neutral wire from the load side of the main breaker/Neutral bar (Before the inverter) to one of the 2 poles. No fuse needed as non of the other neutral wires in your board are fused. It literary only gives a return path for the current that is drawn by the electronic circuits, and even in the highly unlikely, very slim, 1 in a million change that a dead short might occur within this device.. the electronic circuit should fry long before it reaches the 25Amp rating of a 2.5mm wire.. This is just my 2 cents worth...
  7. When you are on municipal supply, do you use the borehole for something else? And can you share how you do the changeover, do you physically need to connect/disconnect something..
  8. Hi Beat these figures are not correct at all, please refer to the SANS regulation for correct figures.
  9. 2620476.vff Just remember you will loose the Config file when you update, so please back it up before you flash the firmware.
  10. Yes you can, pm me your details.
  11. Only in some homes, I a lot of cases, there is loads like lights, stove and geyser not connected after the earth leakage, in that case you would need to use the Main Switch / Isolator to kill the power. It is done in a three phase installation with only a three phase breaker. I personally would prefer a 4 pole breaker and breaking the neutral as well, but its only a personal choice. As long as the Neutral is bonded to earth at the transformer/mini-sub it will be safe. There will be no potential difference between live and neutral and you would not be able to get shocked by touching the neutral. Edit: Unless you disconnect a neutral from the neutral bar, and then hold that neutral wire in one hand and the neutral bar with the other while the load is switched on..
  12. The inverter size. Your inverter is a 3kva/2400watt. In this case your load seems to be a resistive load, so the 3000va will apply. It will take from the panels what it can and add from the batteries to make up the 3000va (Rating of inverter) - losses. The balance then has to come from the grid. 3289 (Load) -2267 (PV Production) -445 (Battery) -837 (Grid) = -260Watt (conversion losses). If you had a 5kva unit, everything in this case would have come from panels and battery, nothing from the grid..
  13. Looks great, but, what does the "now" mean. Will it ever be sold in the future? It would be great to use free software, but what a shock if it stops working after 6 months and "now" you have to pay...
