Inverter charger - fuse at charger and battery?

[Richard10002]

Given that power flows both ways in the cables from an inverter charger to the battery, should there be a fuse near the charger, as well as a fuse near the battery?

 

There is nothing in the instructions about two fuses, but it would seem to make sense to have a fuse in the positive, close to the battery, and a second fuse in the negative, close to the inverter?

Keep the battery cable run as short as possible and use a single fuse in the positive feed.

at high currents any connection will introduce a voltage drop so keep them to a minimum. One fuse, near the battery.

Thanks Chris & Richard.

 

The cable run is about 8m total, (pos +neg). Can't do much about it unless I fit the inverter in the engine bay, or move the batteries... Neither is an option I'm going to do in the foreseeable

 

The fuse will be about 30cm from the battery, so at least that bit is reasonably OK.

 

Thanks again.

the charger will likely be internally fused

I think that they are the circuit breakers !
