Frequently Asked Questions
What is a battery isolator and why do I need one?
A battery isolator is an electrical device that prevents current from flowing between multiple batteries, allowing each battery to be charged independently by the alternator(s). This is essential on vessels with separate starting and house battery banks to prevent the starting battery from being drained by house loads and to ensure each battery receives optimal charge without overcharging.
How does the ProMariner 130 AMP Battery Isolator work?
It uses diodes to create separate charging paths for each battery bank connected to it, effectively isolating them from each other. This ensures that power from the alternator is directed to the batteries that need it most, preventing one battery from discharging another.
Can this isolator handle multiple alternators and batteries?
Yes, the ProMariner 130 AMP Battery Isolator is specifically designed to support two alternators and manage charging for up to three separate battery banks, making it ideal for vessels with complex electrical configurations.
What is the maximum amperage this isolator can handle?
This ProMariner isolator is rated to handle a maximum of 130 AMPs, making it suitable for high-output charging systems commonly found on larger vessels or those with significant electrical demands.
Are the terminals gold-plated on this ProMariner isolator?
Yes, this ProMariner Battery Isolator features gold-plated terminals, which provide superior electrical conductivity and exceptional resistance to corrosion in marine environments, ensuring a reliable long-term connection.
