Figure 4: Battery location and connection details
Although there are many sizes of suitable battery, the sizes we usually recommend for the SIMPLICITY are 12V 7Ah or 12V
12 Ah, depending on the load.
To calculate the exact requirement, use the equation in section 20.1, STANDBY BATTERY CALCULATIONS
The two batteries are wired in
series
to give
24 Volts
.
Connect the
–ve
of Battery 1 to the
black
battery charger lead.
Connect the
+ve
of Battery 2 to the
red
battery charger lead.
The +ve of the first battery is connected to the -ve of the second battery using the FUSED link wire supplied.
When fitting the batteries, take care not to damage the temperature monitoring thermistor
(next to the charger lead
connections). This is used to prevent overcharging the batteries in high ambient temperatures.
Recommended Battery Types:
Small / Lightly loaded systems – Powersonic 12V, 7 Ah;
Heavily loaded systems, or systems requiring longer stand by – Powersonic 12V 12 Ah.
Other makes and sizes of battery may be suitable.
