Can someone please Help me with some Settings?

Postby RobinHaiti on Mon Apr 16, 2018 7:47 am

Hello everyone.

I have an Outback VFX3524 with 12 Trojan 105-RE batteries. I am trying to learn.

I am wanting to equalize, but trying to confirm some of my settings first. Someone else set this up for me a few years ago, but now I'm doing it myself. Can someone help me? I can't find the correct settings anywhere.

Charger Limit: 20
Absorb Setpoint: 29.6
Absorb time limit: 2.0 hrs
Float Setpoint: 27.2
Float Time Period: 1hr
Refloat Setpoint: 25
Equalize Setpoint: 32
Equalize Time Period: 1.5 hrs

Are these ok?

They're probably okay but your voltages could be tweaked a bit, along with your absorb time, as follows (http://www.trojanbattery.com/tech-suppo ... /#Charging) :
Charger Limit: 20
Absorb Setpoint: 29.6 (okay as is)
Absorb time limit: 4.0 hrs
Float Setpoint: 27.0
Float Time Period: 1hr
Refloat Setpoint: 25
Equalize Setpoint: 32.4
Equalize Time Period: 1.5 hrs***

***Equalize time depends on how long it takes to, well, equalize the specific gravities in all your batteries' cells. Here's what Trojan recommends (from http://www.trojanbattery.com/tech-suppo ... Equalizing) :
