  Set of interconnection cables.
• The “ATENG 11495” unit includes the following elements:
• EE-HYB-KIT. Hybrid Grid Inverter Kit with Self-Energy Management.
  This inverter can take electrical energy either from the laboratory power grid (50/60 Hz) or
  from a photovoltaic panel (not included) to supply power to a local load (included) or to store
  such energy in a battery (included). This criteria will depend on the amount of stored energy in
  the battery at any given time and whether or not sufficient solar energy is available to supply
  the energy demand at that time.
  In order to study the different modes of operation of the hybrid inverter, this kit consists of a
  battery, a variable resistive load and several analog DC and AC current and voltage meters.
  Depending on the energy stored in the battery and the energy demanded by the variable
  load, it will be possible to observe the inverter behavior by means of the analog meters
  EE-HYB-KIT
  located at different points of the electrical circuit. For example, it will be possible to measure
  the current flows in and out of the battery, the current consumed by the resistive load and also,
  the current flows coming from the grid in case there is not enough energy in the battery to
  supply the demand of the resistive load.
