Our take on the ProMariner ProIsoCharge Battery Isolator 180Amp 1-Alt 2-Bat

The ProMariner ProIsoCharge 180 is a solid-state battery isolator that splits one alternator's output across two battery banks. It replaces diode isolators and voltage-sensitive relays with digital control, so the start battery is protected and the house bank charges without the voltage drop a diode setup causes. It suits boaters and van owners running a dedicated house battery alongside a starting battery. Compared with diode isolators it avoids the roughly 0.7V loss, and unlike a simple relay it manages both banks automatically.

Pros
  • Zero volt loss isolation for fully charged banks
  • Charges two battery banks from one alternator
  • Protects the engine start battery
  • Replaces diode isolators and voltage-sensitive relays
  • Real-time LED status indicators
  • Ignition controlled operation
Cons
  • Rated 180A, so high-output alternators may exceed it
  • Only handles two battery banks
  • Wiring and installation are more involved than a relay
  • No display beyond status LEDs

About the ProMariner ProIsoCharge Battery Isolator 180Amp 1-Alt 2-Bat

The ProMariner ProIsoCharge 180 is a battery isolator, also called a power distribution system. It is rated for 180 amps and connects one alternator to two batteries. It uses digital control to distribute alternator output while protecting the engine start battery.

It replaces traditional diode-based isolators and the voltage sensitive relays or solenoids that often accompany them. It isolates and charges multiple battery banks at the same time. Isolation has zero volt loss, which allows fully charged batteries and faster charge times.

Real-time LED indicators show the system's status. The unit is ignition controlled.

Questions and answers

How is this different from a diode isolator?
A diode isolator drops voltage across its diodes, so batteries charge slower and less fully. The ProIsoCharge uses digital control with zero volt loss isolation, so charged banks are isolated without that penalty.
Can it charge two battery banks at once?
Yes. It distributes one alternator's output to two battery banks simultaneously while keeping the engine start battery protected.
Do I still need a voltage-sensitive relay?
No. ProMariner designed it to replace both traditional diode isolators and ancillary voltage-sensitive relays or solenoids.
What alternator output can it handle?
It is rated for 180 amps. Check your alternator's output stays within that rating.
Does it work automatically?
Yes. It is ignition controlled and manages charging on its own, with LED indicators showing status.
Where is the ProMariner ProIsoCharge Battery Isolator 180Amp 1-Alt 2-Bat cheapest?
At Consumer Marine Supply, for $124.39, 17% under what the other stores charge, as of our latest check.
Where can I buy the ProMariner ProIsoCharge Battery Isolator 180Amp 1-Alt 2-Bat?
