About the motor speeding up. I explained a little of this in my initial post, but here goes.
What I have found is that when I put a load on the motor it puts the
system "out of balance" which causes batts one and two to drain much,
much faster than they should. When you add a load to battery three, the
motor will speed up. Wait a while and see what happens...no more than
five minutes. If the load you have put on battery three puts the system
back into balance, within that five minutes the motor will speed up
AGAIN (a second time) without you having done ANYTHING. (I said this in
my very first post---go look)
When I'm trying to balance the loads I first put a load on the motor,
then add a load to battery three and the motor will speed up, wait five
minutes, add another small load and the motor will speed up, wait five
minutes, add another small load and the motor will speed up. When the
motor suddenly speeds up again (twice after only adding one load), I
know I am in that 'zone" where nothing is drawn out of batts one and
two, and I can continue to add loads to batt three until it drops out of
that zone (and the motor slows down). This is the hard part though. You
added a load so the motor sped up, which makes it difficult to know if
adding the load really slowed down the motor. You need to add LIKE
loads, so that you know how much the motor SHOULD have sped up. (either
through listening, or rpm's) If it didn't, then you have two
choices...reduce the load on batt three back to where it was, or
increase the load on the motor. You want the motor to operate in that
"zone" which is where all the magic happens. You lose voltage out of the
two primaries until you get there, and you lose voltage out of the
primaries when you leave there, but while you are there, it's Christmas
every day. If you want to be able to run LARGE loads off of battery
three, you need to do it while in the zone. But it is a balancing act,
and it takes PATIENCE. So once you are in the zone, keep track of what
the load on the motor was and what the load on battery three was. Then
it is easy to get back into the zone. You keep seesawing back and forth,
increasing the loads on the motor and then battery three until you have
built up to the point that you are putting out the amount of power off
battery three that you want to put out consistently (enough to run your
inverter steadily), and hopefully that is within the limits of the
ability of your particular motor to keep accelerating. I hope this makes
some sense. At that point you are getting steady power out of the
inverter, your primaries are lasting a really, really long time before
having to rest, and you have the power from the motor for free.
