Single-Phase Power Supply System P2S
Convert a three-phase elevator into a single-phase elevator without major investments
Versatile solution, simple to integrate. Makes elevators easier to install, efficient and safe.
Product details
What It Does
Makes it possible to connect the elevator to a single-phase installation and reduces the elevator consumption to 500W.
It is plug & play, scalable, and eliminates the need for an auxiliary UPS system. Additionally, it allows connection to two solar panels for near-zero energy consumption, making it suitable for both new and existing elevators.
It converts the elevator into a single-phase system with a maximum consumption of 500W, taking advantage of the regenerated energy and with the possibility of connecting it only to solar panels for almost zero consumption.
The P2S intelligent power supply system allows the elevator to continue operating even without power supply and optimizes stand-by consumption, reducing it by up to 30%.
- Connects elevators with a three-phase drive to any single-phase installation
- Allows to reduce the contracted electrical power
- Allows operation during power outages with a high number of trips
- Transforms the elevator into a regenerative one with battery storage
- Optional connection to solar panels for almost zero consumption (not possible with three-phase elevators).
- Troubleshoot unstable supplies
- Extends the life of the inverter and reduces drive consumption.
- Plug & Play
- Scalable
- Compatible with both new and existing elevators
How It Works
Single-phase, regenerative system with integrated storage and solar panel connection option
- Powers any new or existing elevator with a three-phase drive through a simple single-phase connection, consuming a maximum of 450W.
- Thanks to its battery storage, the elevator can continue operating for over 100 trips in case of a power outage.
- Además, puede combinarse con paneles solares para reducir el consumo a casi cero.
Case study
Consumption differences
Note: (actual data) In gray, normal consumption of an elevator from the power grid.
In blue, consumption from the power grid, with a P2S system installed.
Nine days of consumption with a solar+ P2S
On the left, in orange, consumption from the solar panels.
In blue, consumption from the grid for 9 consecutive days.
Network and elevator consumption
In gray, typical consumption of the motor, normally fed from the grid. The motor power remains the same, but, in blue, you can see the consumption with the P2S solar+.
In orange, the energy is generated from solar panels.

Energy Recovery System ERS
Take advantage of all the energy generated by the elevator during braking and save up to 64.8% on electricity.
The Energy Recovery System ERS stores the energy generated by the elevator during braking, reusing it for future trips to reduce consumption peaks.
Emergency Evacuation System E3
Ensures hundreds of elevator trips in case of a power outage.
The E3 Emergency Evacuation System stores the energy generated by the elevator in batteries, providing a high-performance backup storage system in case of a power failure
Smart Power Supply System for Homelifts HISS
Maintains peak performance, reduces consumption, and increases the efficiency of electric homelifts with HISS.
This system reduces maximum consumption to 200W, making it possible to use the elevator in the event of a power cut, and allowing a conventional electric elevator to be easily converted into a solar one, for zero consumption during the day.
