It is said a 12V battery is considered full at 12.5V and empty at 11V
Without going any further into that there are 6 cells in a 12V battery ,each of 2V so working the maths the full charge per cell is 12.5/6= say 2.1V.So 48Volt bank is just a series of cells joined to get 48Volts out .
The full voltage then is 12.5V x 4=50Volts .
The chargers push at whatever they are set to allowing a little headroom so as long as its over 50 volts it will push the bank to full.
Don't be concerned to get it higher ,it just boils off more electrolyte pushing a little harder and taking the actual battery voltage over 12.5 just does it harm in the long run. batteryy manufacturers want you to bugger your batteries as soon as possible so you have to buy new ones . Dave on here has some that are 35 years old! Ask him.
Some people like you, should not comment if they do not know what they are taking about.
tytower , in the GRAPH that
you posted, it clearly shows
STAGE 2 - CHARGING VOLTAGE of 2.35 Volts per cell.~56 Volts CHARGING = 2.35 volts per cell x 24 cells
Your own graph refutes your absurdity.
And worse yet ...
Trojan, a major battery manufacturer with engineers that know way more about Lead Acid batteries than you do,
states, "Absorb Charge at 14.7 volts to 15 volts per 12 volt battery"
58.8 volts CHARGING = 14.7 volts x 4 batteries
60.0 volts CHARGING = 15.0 volts x 4 batteries
The 12.5 Volts that you are discussing is the RESTING VOLTAGE, with no load and no charger connected for at least 24 hours !!!
The Resting Voltage has nothing to do with the proper charging voltage.
tytower ,
you clearly do not know what you are talking about.
Contrary to your bad "boiling" theory, we
must bubble the electrolyte in a Flooded Lead Acid battery to stir the electrolyte.
tytower ,
you clearly do not know what you are taking about.
I FLOAT my batteries at 13.5 Volts.
There is no significant charging even at 13.5 Volts.
tytower ,
you clearly do not know what you are taking about.
Chronic Undercharging a Flooded Lead Acid battery, like you suggest, will lead to sulfation and an early death.
tytower ,
you clearly do not know what you are taking about.
tytower , You are ridiculously wrong. And you need to educate yourself on 3 Stage Charting Methods per
engineers at Trojan, Rolls & Johnson Controls, etc.
And I agree with @db , you should
NOT be giving any battery charging advice.
fabieville ,
WHY did you purchase a Pure Sine Wave inverter that only allows only 57.1 volts max, when you know the battery voltage may be, up to 60 Volts?
If true, that was a very bad choice.
When you Equalize the Battery Bank the charging voltage will be near 60 Volts.
I did a google search for Nova 300 Watt PSW and it states, "
42 V - 60V DC Input"
So, why / how is your Nova inverter limited to a very low 57.1 Volts?
