10. Substitute the values in to the formula below.
The MINIMUM battery capacity (C
min
) required is given by:
C
min
=
1.25 x ((T
fault
x I
fault
) + (2 x (T
alarm
x I
alarm
)))/1000 Ah
=
1.25 x (……. x ……. + (2 x (……. + …….)))/1000 Ah
=
1.25 x ((……. + (2 x (……..))/1000 Ah
=
1.25 x (…………..)/1000 Ah
=
1.25 x ……./1000 Ah
=

Notes:
Battery Type: Powersonic Sealed Lead-Acid.
The maximum battery capacities that can be charged in line with EN54-4 recommendations are:
Panel
Max Battery Capacity
T1204
24Ah
T1216-C and T1232-C
70Ah
The T1204 is only approved for 3.4Ah & 7Ah batteries, The T1216-C & T1232-C are approved for 17Ah
batteries.
The battery charger circuit is a constant voltage type designed for float charging Powersonic SLA batteries.
Attempting to charge batteries smaller than specified (3.4Ah for T1204 & 17Ah for T1216-C/T1232-C) may
result in permanent damage to the batteries.
The T1200B battery box can accommodate 3.4Ah or 7Ah batteries. The T1200B-C battery box is designed to
house 17Ah batteries. Batteries larger than 17Ah must be housed in a suitable enclosure with the Thermistor
mounted inside the enclosure. All fusing must be external to the battery enclosure. See the T1200-C Installation
Manual for details.
