Do you have any tips for good or bad induction hobs to use with my GE system?
GivEnergy inverter power control is fast (faster than it used to be) but not instantaneous. I notice that it sometimes fails to keep perfect track of rapidly changing load such as our coffee maker. I'm planning to buy an induction hob and it's difficult to find information on how they control power. Your thoughts would be appreciated
sunnyjoe I had heard that some brands pulse the power, rather than modulating it smoothly, which is bad for inverters.(I think microwaves doing defrost are similar?) There's a video on YouTube demonstrating it.
We have an AEG and it seems quite well behaved.
I have a Neff induction 5x hob and it seems to provide constant power which the battery deals with fine. Mine is installed to a fused spur and has it's own RCD that was run to my fuse box.
What specifically is your concern about the induction hob? That the battery cannot respond quickly enough?

Yes.
My coffee maker pulses power (small water volume with simple thermostat heat control), In Eco mode, when the coffee machine turns off there is a brief export of power and when it turns on there is a brief import. This doesn't bother me because the coffee machine is only used for short periods. However, if an induction hob used similar on/off pulsed power controls over longer periods, that would be less than ideal.
If an induction machine used other smoother methods of power regulation, that would be much better.

Yes, that illustrates my concern perfectly. How do I avoid this problem?
I have an ElectriQ induction hob which doesn't work well with the inverter at all. At any setting other than 9 it switches on and off every few seconds.
I just figure if the battery will do the toast, I don't mind using the grid for the beans 🙂
Got a Stoves range cooker. The induction hob part seems to work quite well with the GE stuff. It’s the grill that is unfriendly purely because it uses too much!
Our Bosch induction hob seems to be a pretty constant draw, as you would expect with the quality product distinction in that video I guess. I think our Hildebrand Glow is probably going to be the lowest sample interval for power so I will try and monitor/record usage using that next time we are using the hob.
An issue at this time of year is going to be possible variability in heat pump and other usage which might make it difficult to distinguish induction hob usage based only on CT clamp or Smart Meter data.
Belling range oven here. It uses pulse on the hob.
Have a 5 plate Ikea induction hob with bridge zones and multiplex zones. Seems to work fine. Have no idea how all the zones work 😂, but the 5 hotplates all work fine and don't cause any issues with my gen1 and 9.5kW battery.
pwdst We have a bosch.seimens induction hob and watching the Android Inveter Monitor app while cooking on the hob, the readings look pretty normal, even when stuff is on a low simmer.
another vote for the Bosch induction hob. Got ours after having the heat pump installed 12 months ago, so we could stop using gas. Its downside is its limited maximum power, when using several 'rings', but I might replace it when I rebuild the kitchen and upgrade the circuit that feeds it...

Thanks. The Hildebrand Glow is a great device

Me too, Neff 4 ring 13amp plug in which struggles with heavy use. Did not realise the difference the plug would make at the time of buying as I did not research properly.
When it dies I will definitely upgrade and would recommend anyone else to learn from me!
AEG hob works fine on our inverter. It's the garage roller door that occasionally has a hiccup (pause) when closing
