The reason for having an unbroken 1000 mile transmission line, at least for
the existing high voltage DC lines, is to get hydropower from the NW, down
to southern CA and Las Vegas to waste it down there. Not a whole lot of

NiMh is still commonly used in handheld radios. Lithium is being switched
to for may of them, but mostly because of weight, not necessarily other
advantages. It seems like for cars, lithium has a big weight advantage, so
kind of makes NiMh not as important any more. It's a shame that it took us

The last studies I saw (which I can try to dig up) showed PV energy payback
at between 1 and 4 years -- so with a 25+ year lifespan, they should easily
pay back, even in a climate like Seattle or Germany.

I believe the way to do it codewise would be to add a subpanel at the base

I am not sure about the leaf batteries in particular, but my experience
with lithium batteries in general is that voltage cannot be used to
determine SOC for most of the range between 20% and 90% SOC. The curve is
just too flat to be meaningful. Above 90% and below 20% it gets steeper

Ah, thanks ALEC.
I had heard that SRP was doing that.
On the inverter issue, you're going to need one designed for use both with
batteries and grid tie... Or one just for batteries if you go completely off
grid. Either way, your current inverter will not work. For one, it can't mAke

Most of the current battery based inverters can handle a swing from 40

I don't think that swing is from discharge to charge but rather a big

I don't know of any currently available battery based inverters that can
accept a PV array input. They all assume that you are using a charge
controller for the DC power coming into the batteries, and they only handle
the power going out for the DC-AC conversion, or charge the batteries from
an AC
Do you have any metering of motor current? I'm not familiar with how the
AXE controller works with a shunt motor as I've only used them with series
motors, but I imagine that if you are at low throttle, the motor current
could actually be very high, while the battery current is low.
