    Generator or Inverter for residential use?

    Yes. I bought some Tigo optimizers from them recently. Wasn’t sure if they were legit so asked to do a collection of 2 optimizers. After seeing they were legit, ordered 4 more. They operate from a house in centurion.

    Generator or Inverter for residential use?

    Others have tried the aux for the geyser and then moved it back to essentials because hot water, especially in winter is a sort of essential requirement. Another option is to just install a separate changeover for the geyser where it can be powered by grid normally and changed to inverter for...

    Generator or Inverter for residential use?

    I guess loud is subjective. Mine was around 3 years old. The fan would stay on when charging or when there was a power failure. I used it for my garage door so I didn’t mind the noise however I would not have been able to manage that in my lounge while watching tv.

    Generator or Inverter for residential use?

    The router ups is tiny and normally has 4 or 8 18650 cells and is typically for small loads of less than 20w. It also give you a 12v output. That cannot be used for the tv. I’m not sure about which trolley is good. I’ve used the mecer 2400va modified sine wave before and that was loud...

    Generator or Inverter for residential use?

    Are these the only items you need powered? Are you sure you will not plan to expand later? If the answers to both the above is yes, then your total load is 162w. Let’s add 20% for efficiency losses, that takes you to 195. Let’s just say 200 for simplicity. You need it for 2.5 hours, that...

    Generator or Inverter for residential use?

    Perhaps but as I mentioned, I don’t know the details so will not comment further. It’s also not a chance I would take. IMO if you don’t have an earth neutral bond, then you are not compliant with SANS anyway so no further testing is required to check if you are compliant or not in an already...

    Generator or Inverter for residential use?

    This is not entirely true. Your earth leakage / rcd is checking the difference in current between live and neutral and if it’s more than 30mA, it trips. It does reduce the sensitivity but I don’t understand the details fully so will not comment

    Generator or Inverter for residential use?

    It’s actually no difference when the grid is on because the inverter is following the grid live and neutral and the neutral is bonded earth on the grid side, so your reference is set. When grid is not present (meaning you are in islanding mode) the inverter will disconnect both live and...

    Generator or Inverter for residential use?

    Thanks. I think I have posted this explanation here before and on PF. You need to test between live and earth and neutral and earth though. Voltage between live and neutral is controlled by the inverter and will be around 220. The bond is about creating a reference point to earth. For those...

    Generator or Inverter for residential use?

    I think there is also a temperature differential that you set. It will heat the water to the set temperature but allow it to drop a few degrees below that, according to the temp differential, before it turns on again. But I think your problem is what speedster mentioned

    Generator or Inverter for residential use?

    Okay. I guess it’s some that are sensitive and others not. unless you have the whole house on the essential circuit, the big users like geysers, ovens, stoves etc will often cause a short feed in spike when they turn off.

    Generator or Inverter for residential use?

    I’m happy my Landis gyr meter doesn’t trip. Probably charges me but I’ve feedback about 7kw in the past 6 months.

    Generator or Inverter for residential use?

    I don’t really understand what this is doing. The title says it’s an all in one device including solar power, so I would have assumed that it has some input for solar panels like some of the other units I’ve seen. These units normal have an AC input and an AC load ups output. You could simply...

    Generator or Inverter for residential use?

    Okay. But you also don’t have the earth neutral bond, right. I initially connected mine after the RCD and it resulted in trips, so I moved it before.

    Generator or Inverter for residential use?

    1. Before. You should not have RCDs in series as you could end up with faulty trips. Also, if you take it after the RCD, you will end up tripping the RCD when the inverter switches back after a grid failure because the inverter takes a minute to change back and your neutrals and earths are still...
