There is a choice between using a wooden pole
or galvanised pipe for a tower.
The maximum distance from the tower to the batteries
depends on the system voltage.
The Soma 1000 can be sited up to 750 metres away from the
tower if 110 volts is used.
The Soma 400 can be sited up to 300metres away from the
tower at 244 volts and 150 metres away at 12 volts.
