September 2, 20241 yr Hi guys, as the topic says, how do i switch my geyser from solar to grid and from grid to solar when required? Hardware 14 panel 550w with Deye 8kw inverter single phase and 2x Dyness batterries Geyser is a 6bar kwikot superline 600 dual. (Will look at reverse pump later as its dual). I installed geyserwise with 2kw ptc geyserwise ac element. This prefeeds my gas geyser. For the geyserwise element i would like the ability to switch it from grid to solar or from solar to grid on the fly. Can this be done? Currently my stove/oven and geyser are on eskom and everything else on solar. Ideally id like something wifo or something on the db board? Have cbi switches. Any ideas? Thanks

Thanks A 2P switchover switch should work, If you have DIN rails something like this could work: https://www.takealot.com/63a-manual-change-over-switch/PLID93231884?gclsrc=aw.ds&gad_source=1&gclid=EAIaIQobChMIlYX7iKCkiAMV5gsGAB0XFx9NEAQYAiABEgKDQvD_BwE&gclsrc=aw.ds
September 2, 20241 yr Author Okay thank you, and its just a matter of flipping the switch? Wont cause any issues? The geyserwise wont lose memery or anything? Ideally id just leave it on solar, in winter or cloudy days id have to intervene though
September 2, 20241 yr What about simply leaving it on Non-Essentials (or Aux on the Deye, if you want to be able to use it when grid is down) - and then let Solar power it (via zero-export) whenever available? Using a regular timer to have the element run whenever the sun's up, will let you power it off solar whenever the sun is shining - and if it's cloudy, it'll dip into grid automatically.

Ideally id just leave it on solar, in winter or cloudy days id have to intervene though Yes, just flip the switch, not sure how sensitive the geyserwise would be to dips in power. You will most likely experience a small dip in power.
