- | Some solid state isolators have a trigger or exciter input; | + | It is unlikely you will need an HVD with a diode-based isolators because: |
+ | |||
+ | - the isolator can't backfeed voltage back to the starter battery, and | ||
+ | - voltage drops up to 1v in the diodes when passing alternator --> isolator --> house bank | ||
+ | |||
+ | But it is theoretically possible alternator voltage is so high that even with the drop you might want an HVD. | ||
Three lug isolators without exciter input might not be usable with HVD. | Three lug isolators without exciter input might not be usable with HVD. |
