Plastic Production Factory
Project Overview
To help commercial end-users optimize energy consumption, reduce soaring electricity costs, and enhance power supply reliability, this customer deployed a comprehensive solar-plus-storage grid-tied system. The solution integrates a 1,300kWp PV array, 1,125kW grid-tied inverters, and a 1,044kWh energy storage system, delivering a stable, cost-effective distributed energy solution for daily commercial operations.
Core Challenges
-
Rising and volatile utility electricity prices continuously increase operational expenses.
-
Unstable grid power disrupts daily production and business continuity.
-
Heavy reliance on grid power and diesel generators leads to energy waste and higher carbon emissions.
-
Lack of a flexible backup power strategy to manage peak demand scenarios.
Tailored Solution
The project adopts a proven grid-tied solar and storage solution, integrating high-performance inverters with modular battery cabinets to enable coordinated scheduling of PV generation, storage charging/discharging, and grid power.
The system includes:
-
9 × GT3-125K 125kW grid-tied inverters
-
4 × BES-P125X261E energy storage cabinets (125kW / 261kWh each)
Operating in grid-tied mode, the system supports:
-
Intelligent peak shaving
-
High self-consumption of solar power
-
Emergency backup power
-
Minimized diesel generator use
It effectively absorbs excess PV energy, reduces grid electricity purchases during peak tariff periods, and lowers diesel generator dependency.
