SW Compatibility Was: MonitorÆg== brand kerosene heaters

[Travis Creswell, Ozark Solar]

Bill and Steve,

Yes, I have a 1800HP on loan from the local (mid west) distributor who lives
in the same town as me. It still works on the utility.  When I tried to run
it with the 4048 the inverter was not sleeping.  It does seem like it ran it
before off the inverter.  When I get a chance I'll try it again.   I am very
impressed with the unit.  I've measured the drop across the coil at over 50
degrees in heat pump mode and uses under 700 watts.  It still has a good
starting surge (2x) but not near as bad as other motors that start under
load that I've measured before.  Compare it to a 1500 watt space heater that
only uses 700 watts.  I am figuring a average COP of 2.

FWIW, I always tell my customers that they might loose an appliance or two
and some might not work at all on inverter power.  "It's not just a
independent energy system, It's an adventure!"  It's crap that solar energy
is advertised as "cleaner, purer etc" than grid power and I don't appreciate
Trace and others advertising as such.  Even the purest of inverters commonly
available to us (Exeltech) still injects a little noise on sensitive
equipment sometimes.  Even with its draw backs RE equipment is still very
impressive.
