re-inverters

[worktohobby]

Hi all,

On the subject of battery combiners, those marketed today are
intelligent and only combine when a charge voltage of say 13 volts or
better is present. This works very well.

There is no voltage drop like a battery isolator, so if your running
an intelligent converter, your genset battery will get an excellant
charge.
