Sure! But you would need about 4 to 6 times more PV panel surface compared to heating collectors to get the same heating power.

Perhaps the use of space is out of line. The person already has 18x545W panels fitted. Based on PV generated at 27kwh a day he has 9-18kwh unused on a good day. This is for Gauteng. No extra cost to just USE this power for the geyser via AUX port.

any ITS owners willing to please send me a video of their units ? I want to gauge how noisy it will be.

 

I will provide whats app detail via pm if anyone is willing to assist

As I indicated via PM will do so when quiet and once we have used hot water as geyser was hot before sunset.

Thanks sir 

Sir hoping you never do it yet and you can also a decibel reading from any free app on iOS or Android

No rush at all as well

Eventually got down to adding a heatpump for the 250L geyser, eskom usage is now down to 2.5kw - 3kw per day. From my previous 50-60kw this is a big win for me.

 

Heat Pump is a Kwikot HP007, uses about 1900 watts and can heat water up to 75 degrees I have mine set to 68 degrees. It takes the same time to heat as the element in the geyser which was 4400 watts however the element was set to lower temp of 60 degrees. Water is hot in 2 hours sometimes less.

It seems like hot water was more than 50% of your consumption. Based on the cost of heat pumps this is a massive saving and not much work involved.

Enjoy it.......

Agreed the new sunsynk system also plays a big part in the reduction of power from Eskom. Before I would turn on the 250L 4.4kw element during PV hours and only turn on the 150l 2.4kw element after the big geyser was hot. Now I can do both at the same time and they draw 4400 watts together. The Kwikot heat pump for the 250l geyser around 1950 watts and the element in the 150l geyser around 2450 watts only heat this once day.

The heat pump also allows me to have a more battery by 6am (35 percent SOC, sometimes more sometimes less depends what the family is running in house).

Overall the heatpump is gonna save me during the rainy days when no Solar power is coming through and I need Eskom to heat, 4.4kw vs 2kw.

I am totally new with this, but here goes.
I am building a house in the west coast. It is a small house with 2 areas. The main unit is the living/kitchen room and a bedroom with a bathroom. The second area is the garage with a guest unit on top with a bathroom. There will be two geysers.  A 100lt for the guest unit and 150 lt for the main room. What i have at this stage is a Deye 5kw inverter vir a Hubble 5kw battery.
That is enough for my lifestyle and my Budget (-)). I only have space for 8 sun panels, on top of the quest unit. So what will be the best solution if I want my two geysers to go on solar as well.  For example, if i use 5 550kw panels for the house and 3 550kw panels for the geysers.  Can i use my smart load function for the geysers, or do i need to get geyserwise  or elon 100 pv kit or do i need a pv kit with the smart load function. As you can see, I am totally confused.
Please advise.
Thanks

I have a SunSynk 5kW with one Hubble 5.5kWh battery and 8 panels. I run my geyser as a smart load on the inverter. On good sunny days, I have excess capacity left after charging the battery and heating up the geyser. On cloudy days - not much left. So, on a good sunny days, you should be able to run both geysers and the battery completely from the solar panels without using the grid. On cloudy days, you will have to compensate with Eskom.

This is 100% possible with just standard geysers. The only caveat is regarding the use of SmartLoad/Aux: this port contributes to inverter maximum. So if your geyser element, combined with your standard household load, exceeds the inverter/battery maximum (5kW), you'll trip the inverter.

So for example if your house pulls 3kW (someone boils the kettle?) and you have a 3kW geyser powered on via SmartLoad/Aux, you'll trip.

Hence in your case, calculate your expected household loads and when you do, it might make sense to stick to 2kW geyser elements if you'd like them on SmartLoad; and you'd then set geyser timers to have them switch on sequentially to keep under the inverter limit and maximize solar utilization.

In my case I run a 5kW Sunsynk with a 4kW Geyser (far too big for SmartLoad/Aux) and a 3kW (also a bit too big). Swapping out the latter element to 2kW would make putting it on SmartLoad feasible.

However in my scenario they're both currently on non-essentials (nothing is connected to SmartLoad yet) and because the inverter is able to push back excess solar capacity to non-essentials, most of their heating takes place from solar when it's sunny anyway, with Eskom contributing only when solar is insufficient or the household load peaks above 5kW. The only real down-side of not having them on SmartLoad/Aux being that they can't run when the grid is down (eg, during load shedding).

 

So both options - non-essentials and SmartLoad/Aux - are available to you; but just pay attention to your load-vs-geyser-element-size if you go for the latter option as both battery and inverter need to be able to handle the combined load.

Hi, I have a luxpower SNA 6000 off grid inverter, and 6 x 615w Jinko panels.

Can I power a 200l electric geyser without using any grid power? ( thinking about the start up surge )
