MPPT and a DC to DC charger
Hi Everyone, I have 400w of PV and a Epever MPPT controller on my campervan. All is good until winter. So was was thinking of adding a DC to DC charger to charge from the main battery to the leisure batteries. Would I need to disconnect the MPPT before switching in the DC to DC? I'd rather they were both connected to avoid the MPPT shutting down as it will not have power. My worry is that the DC to DC charger will damage the MPPT when charging the sealed lead acid batteries.
