Quoting Lee Hart via EV <[email protected]>:
QUESTION ON A PROPOSED 32/48 VOLT DC MIX:
Since I just monitor the EVDL, I have not learned the correct
procedures to post. I hope that jumping in here with a question will
be acceptable.
Question: Will a vintage 2800 watt, 32 Volt Jacobs wind generator
charge an L16 FLA, Interstate 48 Volt battery?
The Proposed System:
A 48 Volt DC to 120/240 AC Out Back inverter would be fed by a 4000
or 8000 Watt PV panel. My question then, is it feasible to add the 32
volt wind plant to charge the battery on a cloudy day?
My hope is that despite the wire size(for 32 volt) of the generator
windings, the generator field will"see" the 48 volt battery in a
positive way. I could adjust the wind plant governor. I see this as
an experiment so I can use all the help I can get should I proceed in
that direction.
The Goal:
Our Tesla Model 3 rejects the AC output of our present tracking 3 KW
PV 120DC/120AC system. We plan to add the second, independent, non
tracking system since the Out Back inverter produces a sine wave that
is acceptable to the Tesla as was proven by Jerry lilyerd at Sun Energy.
Thanks for the service you provide,
Ron Solberg

Keep in mind that many hand held meters cannot accurately report mOhms. You
should look up the specs on your meter to see what it is actually capable
of.
Indeed, most normal meters are inaccurate below about 1 ohm. Their
own lead wires and internal circuitry adds more resistance than that.
There are special meters for measuring very low resistance values
(usually called "milli-ohm" or "micro-ohm" meters. They usually make
4-wire measurements. Four wires connect to the unknown resistance;
two supply a known current, and the other two measure the (tiny)
voltage produced by this current. This method cancels out the
resistance of the wires and connections themselves.
