Q: Why the GX_R_AUX need to be in it’s own strain:
In principle, you can put the GX_R_AUX directly into a BACS bus, it would work too. However, in larger installations with many
BACS modules in one string, this could be a problem:
Each BACS module has a galvanic isolation between the control and the communication module. The communication module is
supplied with the necessary operating voltage by the BACS bus. However, the GX_R_AUX requires more power than the BACS
modules, which could cause communication problems inside the complete string. The limit of installed modules before this
occurs is fluent and depends heavily on where insed the string you placed the GX_R_AUX during installation. Therefore, this
type of installation is only conditionally recommendable.
Q I habe 34 BACS modules and unfortunately 38 batteries… Can I just set up 34 batteries?
Well… in the end, yes, BACS will monitor and equalylize 34 batteries. The last 4 batteries will be just loaded. But this is not
recommendable. It will lead into problems with the 4 batteries left:
- No monitoring
- No battery management
The problem is normally not that you can add 4 modules later, the problem is, if BACS is running and working, you may forget to
add the last 4 batteries.
