Mounting Instructions
Battery selection for a battery-only installation
The battery selected should have the highest amp hour (Ah) rating possible while still fitting
inside the battery compartment.
The dimensions of the battery compartment are 200 x 235 x 290 mm (W x H x D).
For best system reliability and long-term battery life, the preferred battery and charging regime
is a deep-cycle lead-acid battery and to recharge it when it has discharged to a medium
charge level. The table below shows the number of days the energizer can operate before the
battery requires recharging. The table is based on the energizer operating with an 12 V 80 Ah
battery discharged to 20%. Although operating time can exceed the number of days shown
here, this is likely to cause battery damage and will necessitate frequent replacement of the
battery.

Battery selection for an installation with solar panel
The battery and solar panel must be selected carefully to suit the energizer's electrical current
consumption. This will depend on the position of the energizer Selector switch, the energizer
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 lead-acid battery required for each
model is shown below. This table is based on average usage over seven days with no sunlight.
The solar panel you choose will depend on a range of factors. For

advice, see your PATURA agent to discuss the range of solar panels
available.
