I have set DVCC on my Cerbo GX to share its temperature and selected temperature sensor 1 . Have checked the sensor is giving the correct temperature but the Multiplus still transitions from Bulk to Absorption at the normal set point for 25c which is 28.8 volts when the temperature is 10c degrees lower so should not end Bulk until 29.4 . Is this a knows issue or is there anything can do to correct this ..
My Batteries are Trojan AGM but only Victron AGM are listed so i left it at default , i did the same on Charge Curve .
Hi @AKO
Your 5mV setting needs to be multiplied by the number of cells. The Multi doesn't do that. Enter -60mV there and it should do what you expect.
Thanks John , i couldn't find any mention of that in the manual or online in general however Im sure your right so i have made the adjustment as you suggested and will have to wait for bad weather to try it out . I did notice after i set Temperature compensation to -60mV that the new maximum voltage displayed was 31.5 volts m that equates to a temperature variation of 30c degrees ( 31.5 - 28.8 = 2.7 ) that would handle a temperature range from -5c to 55c . Is my choice of battery type setting correct ?
UPDATE
Weathers bad today so started the generator and happy to report the Multiplus is now applying Temperature Compensation .
