BTW the settings were at 230v and have not changed. Spikes are still a bit weird. The ±3kw that just happened at the end of the graph was cooking.

Thanks. Things seem a little more realistic now in terms of the morning geyser draw being a fairly constant ±3kw but I still have high spikes here and there. It could be a geyser spike timed poorly and very coincidently with a kettle brew but.. weird. Anyway, will keep tracking. The efergy people had some application / architecture problems with data queues which stopped the app from working for a while and it still seems quite patchy. I feel a bit better about an 8kw inverter with about 6600 watts of panels.

Update : I ended up needing to replace the element and thermostat on my geyser (coincidental failure - it has worked fine since 2014 without a hiccup). After that, I also moved the clamp to a different area of my Eskom feed and immediately after I was seeing a draw of 3kw while the geyser was heating. It was likely clamp placement I am guessing. Thanks for the input. My new problem is that my efergy engage hub is just not showing as connected at all and their support team are referring me to a data queuing issue on their side which frankly quite ridiculous as I haven't been able to properly use my efergy engage for more than a week now. Oh well. I suspect my solar install is going to be massively overkill as my estimates were based on high utilisation but I'd rather over-bake it and be less reliant on Eskom than more so.

Yes - it is only clamped around one wire. The engage seems to be accurate otherwise - when my pool pump comes on (1.1kw) my consumption appears to jump up accordingly. See the attached graph. My baseline consumption is around 900 watts during the day - in the afternoon the pool pump came up and took us to around 2000 watts. The early morning ~06h30 to 08h00 is the geyser, so are the other spikes. Afternoon/evening was geyser + pool pump + a furious amount of cooking by my wife lol.

It is my efergy engage that is reporting the draw, but I will see if I can't go and buy a handheld clamp meter and put that across the geyser supply directly, thanks.

Hi all I have a Kwikot Dual 600 (https://www.kwikot.com/product-category/domestic-geysers/dsg-150/) which is probably about 6 years old. I noticed that the spec sheet says it has a 3kw element but it typically draws about 6-7kw. I notice sustained high usage after everyone showers in the morning and then every few hours during the rest of the day, there are probably 15 minute spikes of easily 6-7kw. Is this normal? Should I replace the element or drop the temp on the geyser? Anyone had a similar experience and have any recommendations on how to potentially lower this if possible? Regards, Peter
