Digitally controls alternator power distribution while protecting the integrity of the main engine start battery. Intelligently monitors, isolates and charges battery banks with zero voltage loss, provides priority charging to the battery bank that is under load by taking fully charged batteries offline. Compact and efficient digital design eliminates diodes or the need for multiple voltage sensitive relays to charge multiple battery banks, saving space and cost by significantly reducing installation times. Ignition-controlled Distributed On Deman battery bank management capability and advanced regulator ready with connections provided for alternators equipped with advanced regulators. Models available to manage up to three battery banks on single alternator, or up to four battery banks, on dual alternator-equipped boats.

Comments about Professional Mariner ProlsoCharge Power Distribution System, 3 Battery, 120A:
I installed the 180amp 3 bank ProIsoCharge on my 2007 Jeanneau SO 39i when the factory installed diode-based cheapie isolator failed (you'll know because the batteries won't charge from the alternator). Battery isolators failing is a VERY common problem (exact same failure on a friend's boat - ruined our trip).
The ProIsoCharge unit is a quality, heavily built "isolator" that looks like it will be reliable for many years, not a chiepe diode-based unit or old fashion solenoid system (both of which give problems).
My ProIsoCharge has been in service for one season with lots of use -- zero problems. Works great with the Balmar alternator and ARS-5 smart regulator I also installed. Suggest you purchase one that is rated significantly larger than your alternator for durability reasons. As far as I know, this is the only real quality isolator on the market.
Add a Balmar alternator with the ARS-5 regulator and some Lifeline AGM batteries and you will be very, very happy with your electrical system. I am. (We keep the boat on a mooring and only see a dock long enough to get diesel and water, so this stuff is critical for us).
