. Do have a 50 amp alternator
on the engine but I try to use the engine as little as possible.
As others have mentioned, the diode type isolators do have a voltage drop on the output side (though that is somewhat mitigated by using appropriate diodes, like the Schottky type...]
However, the voltage drop can be compensated for by making sure the voltage regulator
voltage sensing wires are connected to the battery side of the isolator. That way your alternator reg and solar reg, etc., output increased voltage to make up for the loss...
Before installing make sure it is compatible with your alternator and regulator(s) [e.g., typically diode isolators and self-exciting alternators are incompatible...]
I hope this is helpful.
