HOW DOES LEONARDO OFF-GRID WORKS
1. The Leonardo Off-Grid 4kW/5000/48 MG is designed to achieve direct energy
savings through the use of PV and other renewable energy sources;
2. The PV system is managed by the internal charge controller with 4 independent
MPPT inputs ;
3. the inverter provides electricity savings through direct production from renewable
sources or from energy stored in batteries;
4. the Leonardo Off-Grid 4kW/5000/48 MG guarantees continuity of service, in the
event of overload or insufficient energy available from renewable sources, by
switching on the AC grid at AC-IN input;
5. a dry contact for maximum self-consumption allows to activate loads users (water
heater, heat pump, etc ...) increasing its share of energy self-consumption;
6. on the user line, AC-OUT, the energy will be supplied with the following input
priority:
direct self-consumption by the PV modules

self-consumption by storage
in battery

contact for maximum self-consumption

AC-IN emergency power
supply;
7. in the event of a power black-out , all the energy stored in the batteries is used to
cope with the emergency condition until the device is switched off, which occurs at a
residual capacity of 10-20%.
