So I purchased one of these Elon Smart Water Heaters, pretty easy to install and have it connected to 4 x 330W panels all in Series. Yesterday was the first full day of Solar being delivered to the device and it did it's job. Heated the water temp from 39 degrees to about 64 degrees by about 14h00, so overall happy so far. Definitely slower then conventional AC power. Now to organise CoC.

Good morning Forum, I did a quick search but couldn't find anything on the Elon Smart Water Heater, although it seems similar to the Elon100. This product: The Elon Smart Water Heating Unit | Kwikot Has anyone worked with it and have any experience with it? I am thinking of connecting it to 6 x 330W panels which I currently have no use for: Although ideally, 3 would be for my 1 geyser and the other 3 would be for other geyser. Thanks.

Panels are: 2 x Canadian Solar 330W Panels 4 x Mecer 330W Panels

Looks to me like a 3kw (Geyser 1) and 4kw (Geyser 2). Attached are images of Geyser 1 (mounted outside) and Geyser 2 (which has the Kwikot 600 Dual sticker on it). Geyser 1: Geyser 2

Hey Scoobs, Unfortunately no. :(

Nope, this is the only time they run. I don’t have them set to run over night.

On average, geyser one draws about 5kw a day and geyser 2 about 4kw.

Hey Hennie, I’m not 100% sure, but by viewing the draw on the inverter. Geyser one is 3kw and geyser 2 would be 4kw. Panels face north at 21degrees. Max power I’m currently getting from the panels is about 3-3.2kw. I have a feeling the batteries are just never catching up, so they charge but don’t ever seem to hit the 100% mark. So when the geysers kick on, the 3kw draw and 3.5-4kw draw from the geysers take battery power. I’m hoping for a relatively inexpensive way to assist the geysers heating so the dar isn’t as long when they run through the inverter.

I guess what could add as well is average usage is between 400-500W. But additional items that run daily: toaster (2slice) Washing machine (1-2 loads)

Hey Hennie, Current Inverter: Mecer SOL-I-AX-5P Panels: 8x545W connected in 4P2S GEYSER 1 1 geyser is for showers and it’s used at night from about 18:00 by three users (this is the 150l geyser) GEYSER 2 1 geyser is for the kitchen and is purely for washing and occasionally a guest in the guest bathroom (this is the 200l geyser) Geyser 1 runs via the inverter from 11:30 to 13:00. Geyser 2 runs via the inverter from 13:30 to 14:30. Hope this helps. Unfortunately I don’t have much further info with the older style inverter. Batteries are 2 x EasyPower Elithium 51.2V100Ah (5120W) connected in parallel so 200Ah in battery. Utility kicks in at 51V and turns off at 54V on the battery.

Good afternoon Forum, I'm looking for a solution to heating water. I have 6 330W panels that are currently collectiong dust but I would like to use them to assist in the heating of water for 2 geysers (they are 150l and 200l kwivot geysers) at my home. Currently both geysers run on a timer through a 5kw inverter, but they're killing the batteries (2 x 51.2V100Ah lithium batteries in parrallel) and I'm wondering if there is something I could do to assist with warming the geysers before the geysers have to run through the inverter that would help stop them running the batteries down. Thoughts?

If you could, that would be greatly appreciated. Or let me know what the formula is and I can do it myself.

So, ideally, my wiring should look similar to this? Wouldn't running two strings into 1 neg have the same effect of running my old setup? i.e. too many amps through the cable?

Hmmm, but that would mean I would need to run 6mm for each string before paralleling them in the box. A fair amount more to spend in on cable In that case.

Thank you Youda, lets see what others have to say and take it from there.
