THE INTELLIGENT SOLENOID
The Intelligent Solenoid is the heart of the split-charge system and can even be used as a stand-alone isolator. The voltage sensing, timing and all calculations are done internally.
This device monitors both MAIN and AUXILIARY batteries in a vehicle and connects the auxiliary battery when the main battery is receiving sufficient charge.
Switching the alternator’s charge from the main battery to the auxiliary battery is automatic, so you don't have to remember to connect your auxiliary battery.
The Intelligent Solenoid will automatically isolate the auxiliary battery when the batteries are no longer receiving a charge voltage (when the engine is turned off).
Important safety features and parameters have been pre-programmed into the operation of this system. The system will not connect if either of the two batteries are disconnected, short-circuited or too flat to charge safely.
The intelligent solenoid does not interfere with existing vehicle wiring and electrical system.
No ignition wire is required.
Management of a dual battery set can be a simple and minimal as the purchase of the intelligent solenoid. Add battery cables as directed and you are done. Then when time and budget allows, add some sophistication with a dual battery controller that connects to the intelligent solenoid and runs into your cab for complete monitoring and control.
Please download the Intelligent Solenoid instructions and Split Charging System FAQ if you'd like to learn even more about this item.
Some aftermarket parts manufacturers make vehicle specific dual battery trays. If your particular vehicle doesn’t have a tray for the engine compartment, you can also place your auxiliary battery(s) under a seat, in the foot well, in a lock box in the bed of a pickup, etc.
The Intelligent solenoid is supplied with a basic hardware kit and manual. Batteries, cables and terminals are not supplied.
