Starter battery charger activating DC/DC charger

Hi all.

I have noticed that my starter batter charger (60A) is switching my DC/DC charges on.

Is this a bad thing?

No, it will keep the other batteries topped up too.

I have noticed that the multiplus does not charge the LiFePO4’s because the DC/DC’s are doing

all the work.

This does not seem like the best way of doing it. I was thinking if using the Cerbo Gx to deactivate the DC’s when it’s connect to the grid. How should this be done?

Hi @Straycat - Check the charging voltages. Setting the DC-DC charges to be marginally (0.1-0.2) volts lower than the multiplus will give the multiplus priority.

Thank you. Great idea. That way I won’t need to use the on/off function
