I am changing the battery settings in the VictronConnect app for my Smartsolar 150\35 controllers and was wondering how you change\verify what the bulk charge voltage is? I only see settings for Absorbtion, Float and Equalization voltage in my app.
These are the settings I was told to use for my GC2 6 Vilt batteries
Bulk - 14.46v
Absorbtion - 15.3v
Float - 13.4v
Equalization - 15.6v
Thanks
My mppt 100/50 does not have a pre-setting for gulf cart batteries. I'm not sure why. I also can not get the battery specific charging targets from the battery mfg. 100ah Frustrating.
Current settings...Absorp eq 14.4
Float eq ....13.8
Equ eq....16.2
Thoughts?
Thanks...
The short answer is that there isn't a setting for Bulk Voltage limit.
It's strange to me why the battery manufacturer would specify a Voltage limit for the bulk phase.
It would make sense to have a current limit based on the size of the battery, charge with as much current as permissible and then the Voltage limit would be the start of the Absorbtion phase.
Think of it another way, if the Bulk phase is Voltage limited to 14.46V, then how would the battery ever reach the Absorbtion limit of 15.3V?
I think you mean 14.3 for absorption and that 15.3 is a typo
if thats the case then in the victron connect app. under settings then select battery and there you can see the settings you can also change battery type and override the settings
you set the absorption voltage (this is the bulk setting) and once reached then the absorption phase starts, and this is the timed period usually 4 to 6 hrs
then it goes to float.
so bulk and Absorption are used as the same figure (voltage)
found these on the web for APG GC2 Specs
6V GC2's, alias 105's, are bog-stock generic floodeds, and the default Victron settings suit perfectly. They're designed to cycle in golf carts (hence the 'GC', eh). 14.4V Abs & 13.8V float is fine. If in storage 13.2V float would do.
