Hello everyone. Let me start off with A shout out to Will for all the YouTube videos and info the he provides.
I have two mppt 6548 and 4 EG4 life power 48 volt server rack batteries. When charging them up for the first time off my 2000 watt solar array the battery voltage will not go past 54 volts. Is that 100%? Or did I set the charging parameters wrong on my MPPT. For charge settings I used the EG4 spec sheet. Bulk voltage 57 V. Float and absorption 56.5 v.
On setting #13 I do have sbu selected (solar then battery then utility) at 54v.
Any help here would be appreciated. I don’t know if my battery is at 100% at 54 V. I tried calling signature solar and wasn’t able to get the info of what a 100% battery voltage is

According to this chart,

54V is ~99%. Not too bad. Actually, according to some theories (which I instinctively tend to believe), best for longevity.
