High output protection to prevent overcharged banks from damaging neighboring banks
Use on single alternators, dual alternators, single-bank chargers, solar or wind charge applications
Waterproof housing contributes to long life and expanded installation options
Unpacking And Inspection:

How Does This Unit Work?
The ProIsoCharge is installed between the charging source and multiple battery banks. The
ProIsoCharge is activated by the ignition feed (key on position) indicating to the unit that
charging will begin. When the unit is off, it draws no power. The unit will self-test on each
start-up, and begin assessment of the connected batteries conditions.
Beginning with the Start Battery, the unit will charge to 13.3V and then begin charging the
second bank and then the third. Once all banks are at least 13.3V, the unit brings all 4 banks
on line for charging. This process could take seconds or minutes depending on the state of
charge of each bank.
The solid state circuitry can also control backfeeding or when a heavy load such as a windless
attempts to draw from a neighboring bank; the unit will direct the charge to the bank under
load. After the bank under load is fully charged, the rest come on line.
There are many uses for the ProIsoCharge. ANY charging source such as a single output
ProMariner Battery Charger or an alternative energy source such as a wind generator or solar
panel can become a multi-bank charging system.
