I know that a Victron MPPT solar controller has an inbuild temp sensor. This sensor is checking the temperature once a day, probably when there is no sun and no load to the batteries. And compensating according to this measurement.
But how is this compensation working when using the external temp sensor connected to the BMV-702 in a VE.smart network with the Smartsolar 100/20.
Is this configuration compensating continuously, or also once a day.
If this is the case, then there is no reason to install this extra external temp sensor if the MPPT smart solar charger is only placed 0.5 meter next to the battery. It can only be useful if MPPT smart solar and battery are placed in individual spaces. Or in the case of continuous measurement and compensation.
Thank you for an answer.
