Hello, just trying to learn here.
In my 4x4 I use solar (an MPPT charger) and a DC-DC charger to recharge my aux batteries.
The MPPT charger only operates when the vehicle is stationary and the DC-DC charger only operates when the vehicle is moving. The outputs of both these chargers join at a bus bar and carry on down to the aux battery.
One thing that has been bugging me for a while is, do I need any protection on the outputs of the chargers?
EG: Charger A is running and outputting 14v and say 20 amps. Could this 14v and 20A damage the output circuitry of Charger B? Or, should these devices be designed with that sort of thing in mind and should be able to handle it?
I'm just speaking generally as I'm aware every brand will be different and so on.
Should I put something in place to block any incoming charge? If so, can anyone suggest something?
Thanks for any help.
