I'm asking for the solar assembly of my friend on the neighboring boat in the marina.
The installation of the system is as in the attached image. TEMPERATURE COMPENSATION for FLOAT CHARGING VOLTAGE (13.6V - 13.8V) is specified as -3mV/℃/Cell in the datasheet of RITAR brand service batteries included in this setup. The same parameter is specified as -4mV/℃/Cell for CYCLE USE VOLTAGE (14.2V - 14.4V). The same document also gives a value of 6 for CELLS PER UNIT.
VICTRON CONNECT installed on the mobile phone shows TEMPERATURE COMPENSATION as -16.2mV/℃. And it's like this field is not modifiable.
Does this difference between the value shown on the VICTRON CONNECT and the value indicated on the battery datasheet adversely affect the performance of the system? What should be done to correct the negative effects?
Another question is; Which Victron product would you recommend to charge this service bank consisting of 2 RITAR batteries from shore power?
Thank you in advance for the replies and comments.
