Small Energy Storage System

Features and Functions

Small Energy Storage SystemSESS
DIJIYA Small Energy Storage System (SESS)-
provide 5kW~20kW energy storage, and applied to general building elevator UPS (uninterruptible power system),
camping without electricity, mobile/ street vendors, electric AC/DC welder etc.,
such as the energy storage system will replace the traditional diesel generators, excessive volume, not environmentally friendly, air pollution and noise.


1. In response to sudden power outages by Taiwan Power Company, the elevators will continue to operate and no trapped personnel.
2. Provide storage for multiple power sources
3. Small size, 1/10 size of diesel generator, efficient use of space.
4. A standalone power supply
5. With remote monitoring of power usage, passengers can take the elevator safely


Elavator UPS
System can be used as a peak load shifting model or UPS

Intelligent Bus Station Energy Storage System
In remote places, the bus booth is free of cable, can be used with solar panels or wind turbines to provide public Wi-Fi,
lighting, advertising billboards and bus-to-station system power usage.

Telecom Power Solution
The SESS with remote system to monitor power operation replaces the lead-acid batteries in telecommunications room and reduces the cost for manual inspection of lead-acid batteries.
