	Yep, but enough LiPO batteries for a couple of hours isn't too
expensive these days and is getting cheaper steadily. Lead/Acid gel is
still cheaper initially but more expensive long term.

	Yep batteries have much the same problem - except that there's the
option of doing it in pieces consumer side - for example the lighting here
is 12V anyway so putting a battery in the feed for that is fairly simple, a
small UPS would drive the pellet burner and heating pump, a larger one for
the network infrastructure (preferably move as much as possible to 12V or
48V).

	OTOH a central battery arrangement makes hooking in solar and/or
wind charging easier.

	It's all stacked behind a bunch of other projects of course.
