Applications of Energy Storage System (ESS)


Energy Storage Systems(ESS) can be applied to Grid, UPS(Uninterruptible Power Supply) and Residential & Commercial usage throughout the power supply system.

Grid Application

Energy Storage Systems(ESS) help to stabilize power supply of traditional power plants and
renewable energy generating facilities through frequency regulation and peak shifting by integrating batteries to them.
Peak Shifting
* Charge during off-peak times
* Discharge during peak times
Discharge during peak times
Stabilization of intermittent renewable power through charging and discharging
Frequency Regulation
Charge when grid frequency increases
Discharge when grid frequency decreases

Residential & Commercial

By using Energy Storage Systems(ESS), households can save energy generated from solar panels to use it
at times when electricity prices are high or there is a power-cut. Furthermore, Energy Storage Systems(ESS) make it possible to be completely independent from the grid.

Electricity Bill Saving

Charge during off-peak times where electricity rate is low. Discharge during peak times where electricity rate is high


Store solar energy generated from Photovoltaic (PV) panels allowing an energy self-consumption

Emergency Power Back-up

Discharge during a black-out, functioning as a power back-up

UPS(Uninterruptible Power Supply)

Energy Storage System(ESS) can be also used to protect Internet Data Centers and IT facilities which need a stable stream of power supply.


Provide back-up power stored in a lithium-ion battery during black-out or unstable power fluctuation time.
Secure a stable power supply to :
- Telecommunication repeaters
- Base stations
- Internet data centers
- Other telecommunication equipment
Since 2003, BSLBATT provides electric energy more efficiently and reliably as best solution. Powerwall charges by day and powers at night for residential solar system with compact, affordable and easy installation features.
