Off-grid lithium storage system with back-up on generator set

The Leonardo Off-Grid GE Py was conceived and specially developed for the production and storage of domestic energy; combined with photovoltaic modules and Pylontech lithium storage batteries (US2000 Plus and US3000) it feeds the home until it is completely self-sustaining.

The Leonardo Off-Grid PY makes the use of energy produced by photovoltaic modules easy and immediate, for the supply of domestic users, with the aid a generator (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. The AC input which the system is equipped with guarantees continuity of operation of the users without perceptible discontinuities both in the case of low battery due to the reduced renewable energy available, and in case of power required by the load greater than the capacity of the appliance.

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 Leonardo Monitor® APP. In addition, remote control allows technical assistance, setting of operating parameters and system firmware updates.
