How the control system works

A patented "intelligent" device ensures optimal management of the available energy sources, without overloading the mains network and protecting the storage batteries against a premature wear due to overuse. The system has been designed to draw a maximum of 3 kW from the mains network, equivalent to the power provided under residential electricity contracts. During actuation of the lift a regulator compares (in real time) the power needed to operate it with the mains power actually available and makes up the difference with a system of batteries that can be recharged using mains electricity or photovoltaic panels.

 

Efficiency always guaranteed

The storage batteries are charged individually. Therefore, if one battery malfunctions or is damaged, this will not affect the normal operation of the lift. In the event of a blackout, the batteries will guarantee a sufficient supply for at least 80 trips under medium load.

 

Integration with renewable energy sources

If the building is already equipped with a photovoltaic system, the energy needed to operate the lift can be drawn entirely from it. In the absence of such a system, SELE can supply a single panel of about 1 sq. m for 240 W of peak power, sufficient to replenish energy in the batteries.
