Supply concepts

The following table gives an overview of the possible supply concepts including the respective advantages and disadvantages:

Supply conceptAdvantagesDisadvantages
Supply by primary battery
  • Minimal installation effort
  • No energy source required at the installation site
  • Requires a cyclic replacement of the power supply unit
Supply by PV module
  • Self-sufficient operation
  • No energy source required at the installation site
  • Due to the energy supply using a PV module, there is a dependency on insolation
Mains operation (230 V AC)
  • No cyclic passing by the measurement site needed
  • No dependency on insolation
  • Energy source required at the installation site
  • Power supply unit required
  • High installation effort
DC power supply (12...32 VDC )
  • No cyclic passing by the measurement site needed
  • No dependecy on insolation
  • Energy source required at the installation site
  • High installation effort
