    switched from old diode type

    my traditional diode setup kept dropping voltage and getting hot, so i swapped to this digital 120 amp unit. the priority charging software actually works by shifting current to the house bank when needed. delivery took an extra day but performance is spot on.

    good isolator minor box damage

    box was slightly squished when the order arrived but the unit itself is solid. hooked it up to manage my 12v dual battery bank on the boat and it keeps the starter battery protected nicely. zero voltage loss is real compared to my old analog isolator, charges much faster now.
