The Leonardo Off-Grid GE was designed and developed specifically for the production and storage of domestic energy; combined with photovoltaic modules and lead storage batteries, it supplies the house with power until it is completely self-sustaining. The Leonardo Off-Grid GE makes it easy and immediate to use energy produced by photovoltaic modules, for powering domestic users, with the possibility of using a generator set (back-up) in case of reduced renewable energy. The system provides independent MPPT inputs via a dedicated charge controller: this technology implements a search circuit for the maximum power depending on the voltage and current of the PV module, always maximizing the energy supplied. By connecting a generator to the AC input, the system guarantees the continuity of operation of the users without perceptible discontinuities in case of low battery due to the reduced renewable energy available. In fact, the generating set simultaneously manages the power supply to the loads and recharges the battery bank. By combining the WRD – Leonardo Datalogger it is possible to monitor your system and view historical data from anywhere thanks to the web portal and the my Leonardo app. In addition, remote control allows technical assistance, setting of operating parameters and system firmware updates.
