Standby current calculation in accordance with EN 54-4
Formula (1) gives the maximum panel current required to provide a specific
buffering time (I
max,Standby
).
Formula (2) gives the maximum panel current with simultaneous
consideration of the battery charge (I
max,A
).
According to formula (3), the required standby current of the panel (I
nom
) is
based on the smaller value of the two maximum current values of the panel.
Parameter:
-
t
Standby
= buffering time in hour
- I
Alarm
= maximum alarm current (I
max,B
)
- C
Batt
= battery capacity in Ah
The following capacities are feasible:
-
24–26 Ah and 36–45 Ah for 2 batteries
- 48–52 Ah and 72–90 Ah for 4 batteries
