I have ordered a couple of these power supplies to play with:

They'll take 10-60V as input, and boost it up to 80V - as long as the output voltage exceeds the input voltage.
They're rated for 600W.
On my boat, I have a battery bank for the electric motor at 48V, and a second bank at 12V for the "house".
The thought was that perhaps, for short periods of time, in an emergency, could I run the 48V motor from one of these tied to the house battery?
The simple answer should be "yes, at low power".
The more complicated issue is if I want 1000W or so.
Can I safely tie the output of two of the voltage pump power supplies in parallel??
Should I put a diode after each one before tying them together?
Or maybe a very small resistor?
