WATTA

System for PV installations

WATTA is part of a PV installation system design for the production and management of electricity in domestic and industrial conditions. Its most important advantages are: power regulation, data transmission encryption, indirect current measurement, real-time access to power measurement, low power consumption for own needs (<1W), wireless connection to the Internet, implementation of the Smart Home function and high measurement quality. The technology on the basis of which our product was created is based on modern process technologies that use high-quality reading with the possibility of fast and effective data transfer.

WATTA meter

Bidirectional meter

WATTA meter is a bidirectional meter used, among others, to measure the energy flow and determine the consumption profile. It communicates with the WATTA IoT module, transmitting data on real-time energy consumption.

  • Current measurement with high accuracy
  • Low energy consumption itself
  • High thermal resistance

Application: home and industrial PV installations

WATTA IoT

remote communication module

Used to collect information from devices of the WATTA System. It also enables the connection or disconnection of receivers, typical for Smart Home systems, and communicates with the WATTA meter 2.4 GHz. It manages WATTA inverter and sends data to the cloud via the Internet .

  • Allows full configuration of modules
  • Clear interface
  • Fast and reliable
  • Available in a browser

WATTA converter

DC / DC converter

WATTA converter allows you to connect a home energy storage on the DC side of the installation. It does not need digital communication with the inverter. It allows to connect the energy storage to the grid without the need to replace the inverter.

  • Easy to install
  • Connection to the installation on the DC side
  • Warranty and efficient service

Application: home PV installations

WATTA battery

home energy storage

Watta battery is the perfect solution for prosumers who already have a PV installation. In conjunction with the WATTA converter, it allows you to easily expand your home power plant with an energy storage.

  • Four different battery capacities
  • Possibility of expanding the warehouse with new modules
  • Warranty and efficient service
  • High quality and safety of use
