Its unfortunately an inherited system so I’ve got to make the best of what I already have.
Its a 3 phase house on a 3 phase inverter with solar etcc so all of the geysers are 1000w - 1300w elements, pool pump 750w etc… to help balance and not overload any phase.
The bulk of my power management on high draw devices like kettles, microwave, geysers, pool pump, aircons etc… is done through Home Assistant with smart switches and works very well for me, I’ll do things based on battery SOC, time of day, loadshedding status and so on.
I am wanting to get the geysers off and was looking at possibly going with gas geysers but perhaps solar geysers are a better solution, I have enough spare roof space.
Would you mind sharing some info on the solar geysers you’re referring to?
I think Geyserwise have a great solution with this offering (which I have)
It’s a DC system so doesn’t need an inverter.
The PTC element stops heating at 80 degC so it can’t boil the geyser even if the control fails (This is done by enabling the MPPT with the controller)
PS: I see they now have an inverter version. I’m wary of this but my guess is they want a competitive product when tendering since this doesn’t require a PTC element…
PPS: Redirecting...
PV panels @R1/W!
Thanks Richard, I’m definitely going to look into going this route, I have solar panels that are partially shaded so will look to use those for the geysers and add more panels to an area on my roof that gets no shading to improve the solar performance.
Overall this should save quite a bit of electricity and should pay for the Geyserwise option quite quickly.
