Hello erveryone,
is the MPPT save against a external power supply parralel to the output connector and less voltage than the output of the MPPT or must I save it by a diode to prevent reverse current to the MPPT.
The question is couse of the Battery Life Algorythm that can cut the output voltage but the load has to be on 24/7. So the external PSU can take the load on the output of the MPPT if it shuts off the output connector.
