Battery selection for solar installation
The battery and solar panel must be selected carefully to suit the energiser's electrical current
consumption. This will depend on the position of the energiser selector switch, the energiser
model being used and the amount of sunshine at the location of the installation.
As a guide, the minimum amp hour (Ah) rating of the 12 V lead­acid battery required for
each model is shown below. This table is based on average usage over seven days with no
sunlight. It takes into account that the solar panel is pointing directly south, without partial
shading and is operating from spring to autumn. Should the battery voltage drop too low, it is
recommended to switch the devices to half power or the battery needs to be recharged.

Warning:
Ensure that the battery is disconnected from the energiser before connecting the
battery to any mains­operated (line­operated) battery charging device. Failure to observe this
precaution could result in damage to the energiser or the battery. Regular recharging of the
battery is essential. Use a suitably rated battery charger to recharge the battery. Refer to the
battery manufacturer's recommendations.
1. Disconnect the battery from the energiser
2. Attach the positive (+) battery charger lead to the positive terminal of the battery, and the
negative (­) battery charger lead to the negative terminal on the battery.
3. Insert the battery charger's input power plug into a mains or line socket and turn on the
power supply.
4. After the battery is charged, disconnect it from the battery charger before connecting it to
the energiser.
Over­charging the battery will reduce its life. Do not exceed the recommen­
dations of the battery manufacturer on recharging the battery from a mains­
powered (line­pow ered) source.
