Energy Storage System Provides Peak Shaving with an AC Power Conversion System PCS

Peak Shaving is becoming more and more popular as a means of conserving energy. This Energy Storage System is charged off the utility grid in off peak hours at very low electrical cost and then discharged during peak periods to dramatically reduce demand charges.

Peak Shaving works because you’re providing energy that doesn’t get billed by the power company. You’re not reducing usage; you’re altering the source of the energy. Here are 3 ways you can achieve Peak Shaving:

1.   Use an alternative localized power source during peak times of day.

2.   Improve your energy efficiency.

3.   Utilize solar energy battery storage.

The 1MWh Storage System makes use of a localized power source by the use of a Battery Pack, a Battery Management System (BMS), and an AC Power Conversion System (PCS).

Ask us about the components of a Power Storage System because we can tailor-make a Peak Shaving System in any Kilowatt range above 250 kW per module.
