On-board installations often comprise two or more battery groups, such as starter battery, supply battery and/or batteries for bow thrusters and navigation equipment. Here it is important that these individual battery groups do not interfere with each other and are insulated. This, of course, means that the charging system must also be isolated. However, this makes the charging process more complicated, as either the alternator, the generator or the charger has to recharge the batteries one by one. When choosing isolating diodes/relays, always keep in mind the maximum possible charging current. For example, if your alternator has 50-70 amps output, a 70 amp isolating diode will be enough.
