Leonardo PRO X

On-grid photovoltaic storage system

Leonardo PRO X is the ideal storage system both for retrofit photovoltaic plants (already equipped with AC On-Grid string inverters) and for new photovoltaic plants (with external charge controllers WRM30+).

In the event of a power outage, the Leonardo PRO X continues to supply energy at maximum power, thus guaranteeing continuity of operation without perceptible discontinuity of users.

The Leonardo PRO X is equipped with an integrated display and realtimemonitoring as standard It will therefore be possible to monitor your system and view historical data from anywhere thanks to the web portal and APP my Leonardo®. In addition, remote control allows technical assistance, setting of operating parameters and system firmware updates.

On new systems, the system connects in DC to the WRM30+ external charge controllers.
On retrofit systems, the system connects on the AC side to the inverter already present.
