Calculation Of The Charging Time; Use As A Power Supply - Victron Energie Phoenix Smart 12/30 (1+1) Manual De Instrucciones

5.6. Calculation of the charging time

A lead battery is about 80% charged at the start of the absorption phase.
The time T until 80% charged can be calculated as follows:
T = Ah / I
In which:
I is the charging current (= current from the charger minus any current due
to a load).
Ah the number of ampere hours that should be charged.
A full absorption period up to 8 hours will be required to charge a battery
100%.
Example:
Charging time to 80% for a fully discharged 220Ah battery when charging it
with a 30A battery charger: T = 220 / 30 = 7.3 hours.
Charging time to 100%: 7.3 + 8 = 15.3 hours.
A Li-ion battery is more than 95% charged at the start of the absorption
phase and will be fully charged after about 30 minutes of absorption charging.

5.7. Use as a power supply

The charger can be used as a power supply (a load is present but no battery is
connected). The supply voltage can be set using Bluetooth or the VE.Direct
interface.
When used as a power supply, only the BULK, ABSORPTION, FLOAT and
STORAGE LEDs will light up and remain lit.
When the charger is set up as a power supply, it will not respond to the remote
on-off.
If the MODE button is pressed while using the charger as a power supply, it will
return to the pre-programmed NORMAL charging algorithm.
