All the time the aggregated cost of the PV panels and battery storage
are so high I cannot see solar to electric induction being viable.
Currently  any battery storage I can buy is a couple of times more
expensive than buying from the grid in UK so it doesn't pay me but it
may pay me to heat water from excess PV electricity. Just as PV panels
have halved in price as production capacity has increased it looks
like LIon batteries are coming down by ~15%  as installed capacity
doubles, whether there is enough lithium  mined to sustain this is
another matter and there are other storage technologies.

Michael what is the common failure mode of fancy electronics in your
environment?

The circuits for induction heaters seem remarkably simple, a couple of
MOSFETS  in push pull oscillating at ~150kHz  and a simple control
circuit (the one I bought following Nikhil's promulgation is too
coarse on the control side) but I see no reason to store or distribute
even DC electricity at such a low voltage, 48V seems more sensible
and then the MOSFETS handle less current.
