Isolation Diodes & Charging Distributors

- Isolate your on-board charging system -

Why isolate the charging system on boats?

Many on-board installations comprise two or more battery groups, such as starter battery, supply battery and/or batteries for bow thrusters and navigation equipment. In such installations, it is important that these individual battery groups do not interfere with each other and are appropriately isolated. 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. 

What is important when choosing isolating diodes & charging relays?

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.

I didnt need the very heavy catalogue and it added to cost of postage and packing. However it is a good read and I will use it.
