Common Concerns Answered
Is installation complex compared to a basic battery switch?
Installation requires more technical understanding than a simple battery switch, specifically involving connections to the alternator and engine run signal for the 'AC' energize input. However, for a dual battery setup, it's a moderate complexity installation.
Will I understand the 'AC' energize input function?
The 'AC' energize input is a specialized feature designed to ensure alternator engagement with modern electronic systems by providing a controlled current. It prevents potential issues with alternator start-up in sensitive systems, a common concern addressed by this design.
Can this isolator manage more than two batteries?
The Victron Argodiode 80-2AC is specifically designed for systems with two batteries. For configurations requiring more than two batteries, a different model or system design will be necessary.
Frequently Asked Questions
What is a battery isolator and why do I need one?
A battery isolator, like the Victron Argodiode 80-2AC, is a marine electrical device that uses diodes to allow a single alternator to charge multiple battery banks independently. You need one to prevent the discharge of one battery from affecting the other, ensuring that your engine starting battery remains charged while your house battery powers electronics.
How does the Victron Argodiode Battery Isolator 80-2AC work?
This isolator uses Schottky diodes to direct charging current from the alternator to each battery bank separately. It prevents current from flowing backward between the batteries when they are at different charge levels. The 'AC' energize input ensures the alternator activates correctly with your boat's electrical system.
What is the voltage drop of the Victron Argodiode Battery Isolator 80-2AC?
The voltage drop across the Victron Argodiode Battery Isolator 80-2AC is approximately 0.3V at low current and around 0.45V at its rated 80A output. This low voltage drop is a key benefit provided by the high-efficiency Schottky diodes.
Can I charge two batteries simultaneously with this isolator?
Yes, the primary function of the Victron Argodiode 80-2AC is to allow simultaneous charging of two separate battery banks from a single alternator.
What is the 'AC' energize input for on this isolator?
The 'AC' energize input is a crucial feature designed to ensure the alternator engages correctly, especially with modern electronic engine management systems. It provides a specific current-limited signal to initiate alternator output, preventing charging issues and premature battery aging.
