Solar parks and other solutions

Self-consumption PV solutions (Zero grid injection)
Given the requirements of the various electricity distribution companies to zero-grid injection, we have extended these options to large three-phase photovoltaic solutions VONSCH. The high adaptability and robustness of our solutions makes it possible to use them under very strict conditions of some distribution companies.

For more information, please contact us at sales@vonsch.sk .
Genset Fuel save solutions
Together with our partner, P.U.R.E , we have developed solutions to reduce fuel consumption of (not only) large diesel gensets. It is a customized solution made according to the equipment, infrastructure and requirements of the end customer.
Features:
  • keeping the genset at a defined minimum load - guaranteeing grid stability
  • integration with ComAp controllers for managing and syncing multiple gensets
  • Remote Administration, diagnostics and visualization, made to fit customer requirements and needs

Off-grid solutions
In addition to the classic "grid-tied" PV solutions; we also offer off-grid solutions without the need for any distribution grid or generator.Our solutions rely on the quality and reliability of the three-phase FOTO CONTROL and GSE CONTROL inverters, and of course the quality of LG Chem ® Li-ion batteries or Hoppecke ® lead-acid batteries and complete VONSCH charging and discharging management.The range is from a few kWh capacity and 2 kW peak power, to a capacity of several MWh, with a peak power rating of more than 1 MW.

Active compensation of reactive power
Active power factor correction (not only) for photovoltaic power plant is possible thanks to compensatory unit UNIKOMPENZATOR . UNIKOMPENZATOR allows to compensate the power factor in range from -0.95 capacitive to -0.95 inductive. It is also possible to compensate on high voltage side, when using an external power factor measurement.

Monitoring and remote access

RM-WEBi
The module RM-WEBi can be connected to FOTO CONTROL 1f inverters and FOTO CHARGER solar chargers to provide visualization of data from the devices through a web page on the local network. Website is compatible with most commonly used browsers. This page is also compatible with mobile devices like smartphones and tablets. RM-WEBi To access the Internet, it is necessary to ask for the public IP address at your Internet service provider or administrator and configure redirection in the local router.
Features
  • Individual device mountable on DIN rail
  • 24V DC power supply
  • 1x Ethernet RJ45
  • 1x Modbus RTU RS485
  • Maximum number of connected devices: 10
  • Možnosť archivácie dát na SD kartu
Functions
  • Simple WEB page (HTML5 a JavaScript)
  • E-mail notification
  • Simple block diagram of installed photovoltaic system
    RM-WEBi
  • View the basic parameters of the inverter and charger
    RM-WEBi RM-WEBi
  • Archiving - Backup of collected data (.csv file)
  • Monitor - Parameters monitoring according to the selected ID
  • Admin access - setting the basic parameters of the system
  • Battery Management (for hybrid photovoltaic system, or off-grid system) - setting the parameters of the battery, battery charging modes
Complete monitoring of power plant with statistics and archive of production
Power plant monitoring made according to customer specifications. It provides comprehensive information on the status of the inverters, power plant itself and its components.
Features:
  • Web-based visualization, secure access to the Internet through Ethernet, GSM or DSL
  • Automatic notification of alarm status and summary reports via E-mail, SMS or FTP
  • Backup of collected data
  • Telemetry - Remote access to control system of the power plant
  • Expandable with almost any accessories (weather station, power and power factor control....)
Components:
  • EWON - industrial modem-router, creates dynamic web pages, data archives, manages alarms, sends information to the user, or creates a VPN tunnel to the local network
  • PLC VIPA - communicates with inverters (MODBUS RTU), evaluates the summary variables, processes the signals from external sensors, controls external devices, provides data for further processing
  • NAS FTP - storage of the collected data, providing the necessary capacity of the archive
  • Weather station - provides weather information
