  • Page 23: Workflow

    PV Blocks system Page 23 2.2. WORKFLOW The PVBlocks solution is a modular system dedicated to the long term measurement of PV Mod- ules and all its relevant parameters. There are several PVBlocks available: IV-MPP The IV-MPP Block is an autonomous measurement and control unit that directly inter- faces to an outdoor load.
  • Page 24 The IV-MOD connects the PVBlocks system to an external MODBUS network. It is used to create an interface to weather-stations and digital sensors. Currently the PV-MET-500 weather station and the EKO MS-90 DNI system are supported. Workflow The workflow consists out of 4 steps: configuration, data collection, iv-curves and analy- configuration: The user defines the PV-Modules that are connected to the different loads (IV-MPP).

  • Page 37: Scheduler

    PV Blocks system Page 37 In this page you have to set the correct time zone and coordinates of the location. This is im- portant for the calculation of sun path. The system works in the background with UTC time values; therefore you will have to set your time zone in order to get the correct values locally.
  • Page 38 PV Blocks system Page 38 As a default the system measures the values at a one-minute interval. This means all temperatures, irradiances, meteo-data and the current/voltage pair of each PV-Module are stored. It is not possible to change this interval. When something changes in the PVBlocks configuration, for example a new PVBlock is added, the scheduler needs to be updated.
  • Page 39 PV Blocks system Page 39 When the scheduler is paused, no measurements are taken anymore. This is made clear by the red warning area on top of the screen. Pressing the Reset Scheduler button will make sure all PVBlocks are configured cor- rectly.
