Charge Combiner 3

2 Input Split Charge for 3 battery system boats

The advanced digital, Charge Combiner 3 is designed for marine applications that typically have 2 engines, each with an alternator feeding a shared House battery bank.

Default settings are suitable for the majority of applications, however custom settings such as longer time delay and or differing pull-in and/or drop-out voltages can be easily changed in-situ via the optional Interface and Software.

Heavy Duty 200A contactors.

Extremely low power consumption by controller unit, and auto-seeking of source supply voltage in the event of a flat main battery, to supply automatic emergency start.

Batteries unsuitable for cranking duty are programmed out by installer when fitting.

Discharging batteries automatically isolated to prevent drain from other batteries. All batteries individually isolated when not charging from alternator. Isolates supply during over-voltage conditions (adjustable). 

Typical Applications:

Marine applications with 2 Alternators and a shared House bank.



  • Designed for vehicles and boats with 3 battery systems made up of Engine battery and 2 Auxiliary battery banks
  • Baks 2 and 3 can be timed delayed in to reduce sudden full load on the alternator
  • Battery prioritisation to protect against system overload
  • Intelligent automatic emergency start
  • Over-Voltage isolation
  • Very low power consumption
  • Available in 12V or 24V
  • Easy to install
  • 5 Year warranty
