Power-Display is dedicated to monitor renewable energies from photovoltaic, solar thermal, hydroelectric, geothermal.

Display for photovoltaic implants
mod. PWD15-C3-TC

Power-Display can be installed inside a building or outdoors. It allows the owner to monitor its efficiency and primarily it informs the public of the existence of the implant and its efficiency in terms of energy and carbon dioxide emissions avoided, and then it highlights the contribution that the implant provides for the environment protection.

Bios Elettronica manufactures eleven electronic standard models to which you can add custom versions with additional fields (see below). The standard versions differ mainly in the size and environment of use. The three smaller models are for indoor applications, others are for outdoor installations. The outdoor models are naturally weatherproof (IP54) and (very important feature) are made with advanced technology and components that make them super bright and therefore readable even at peak sunlight.  

Standard Models

Specifically Power-Display shows the following three data (on request you can add other fields):

• Power output (Watt/kW)
• Total energy output (kWh/MW)
• CO2 emissions saved (kg/Ton) 

 

Additional Fields

Upon request we can add other data fields:
photovoltaic implant's days of working, tons of oil saved, daily energy production, solar radiation, time, date, outside temperature and other weather data.

Links and interfaces

Power-Display can be connected to inverters, energy meters and data loggers. The display is available in several interfaces:

• IMPULSE
  Interface for connection to inverters, dataloggers, analyzers and energy meters with impulse output (standard S0).
• RS485
  Serial interface RS485. Available in master and slave versions for the different inverter/datalogger/analyzer/energy meters types.
• Ethernet
  Interface for connection through ethernet, directly between display and energy meter/datalogger or through a local network (LAN) or interconnected local networks (VLAN).
• Modbus
  Modbus interface is used to interface Power-Display to a PLC/PC or datalogger in “slave” mode with Modbus RTU Slave protocol (available in RS485, RS232 and Ethernet).

With the solutions listed above you can connect Power-Display to most popular inverters, dataloggers, energy meters and analyzers:

Programming Mode During the installation you need to set some values. You can program the Power-Display by the infrared keyboard TK5 provided with Power-Display. TK5 keyboard allows you to set:

• Total energy produced.
  This feature allows to correct the value given by the Analyzer/Energy Meter which, for many reasons, can't be the real one. Examples: the photovoltaic implant is activated before the connection to the Network Analyzer; The Analyzer is disconnected for maintenance; The display is connected to an Energy Meter with impulse output subsequently, so the Energy Meter already accounted energy (Impulse Energy Meters don't give the value relative to the total energy produced and so the count is delegated to the Power-Display's CPU).
• CO2 factor settings. The display's software estimate the amount of carbon dioxide (CO2) not issued in the atmosphere according to the following conventional formula: 1 kW/h produced = 1 kg of CO2 x FCO2 (CO2 factor). If it isn't specified differently in the set-up, the system uses the CO2 factor=0,40351 (source: Greenhouse Gas Protocol 2010).

With the TK5 keyboard is also possible to set the following useful parameters to conform the system when the Power-Display has to be connected to an impulse output device:

• Pulse weight: from 1 Wh to 999.999 Wh (ex.: 1 imp = 10 Wh or 1 imp = 1 kWh);
• Pulse duration: from 1 ms to 999 ms (ex.: 10 ms; 100 ms; 200 ms; 300 ms);
• Impulse frequency's Minimum threshold to which you see instantaneous power = 0 (according to the photovoltaic implants' power and according to user's preferences).

Graphics and writings
Power-display can be sold in standard version only with standard writings or in custom version with graphics, logo and images provided by the customer. The customization is performed with four-color printing on calandered polyester film, high resistance against atmospheric agents, UV rays, detergents and moderately aggressive vapors.
