How to set the right temp compensation value without an external temp sensor?

EasySolar; Multi 48/3KVA, MPPT blue 150/70TR style, CCGX... unfortunately there is no BMV monitor installed and batteries are sited on a isolated compartment (delta temperature is wide), electronics in the same room but outside of the batteries enclousure. Wich would be the better temp comp value to use here?

Through the CCGX could the readings taken by the Multi´s temp sensor be shared with the charge controller?

No the temp compensation of the “Multi part” , the so called ve bus temperature reading, is not used to compensate for the MPPT charge voltage. So this Ve Bus temperature compensation is is incoming AC power. The setting in the MPPT is for the PV charging.
