Battery Isolator / Combiner

Battery Isolator/Combiner

With the Magnum Battery Isolator/Combiner, you can stop trying to figure out how to get your RV house batteries and chassis (engine) batteries to charge from the same source. It takes all the guess work out of your RV's charging system. There isn't any complicated wiring and expensive equipment to deal with.

This battery isolator is an innovative two-bank battery isolator/combiner designed to monitor and charge both battery banks by using a portion of the current that is charging the main (chassis) battery bank to charge the Aux (house) batteries. It can allow up to 25 amps of charging current but if more is needed an optional solenoid drive is built in. It has high and low battery cut-out protection to prevent over/undercharging and automatic 12 or 24 volt operation.

With oversized terminals for easy connection, and basic design, the installation of this battery isolator/combiner is as simple as it can get. The Battery Isolator comes with detailed installation instructions with full color diagrams and drawings.

Some features are:

  • Compatible with 12 or 24 volt Systems
  • Auto-detecting input voltage (12, 24V)
  • Transfers up to 25 Amps
  • Solenoid drive for ampacity requirement greater than 25 Amps
  • Over-temp shutdown
  • Wide voltage range allows maximum charging flexibility
  • Adjustable Voltage settings
  • Over-current shutdown
  • Front panel LED's for status and troubleshooting
  • Reverse polarity protection
