Engineering and installation of 1MWh BESS and 300kW PV system
Client: Fresh and Frozen Storage
Project: logistics base for fresh and frozen products
Site information: logistics facility with a total built-up area of 10 000 m²
Location: Sofia, Bulgaria
Range: photovoltaics 300 kW | BESS 928 kWh
Year: 2025







Project description:
Logistics base for fresh and frozen goods with an existing photovoltaic installation for own supply with a capacity of 998 kWp.
The logistics has constant consumption 24/7 and a surplus of produced energy mainly in the spring and in the summer. Excess production is limited
through the inverters (at this point).
PV Installation:
- Peak Power: 300 kWp
(additional to an existing PV installation with a peak power of 1 MWp) - Invertors: 2 x Huawei SUN2000-100KTL & 2 x Huawei SUN2000-50KTL
- Structure: Aerocompact
- Type: Own consumption
Batery Energy Storage System (BESS):
Integration of a BESS with the following specifications:
- PCS: 400 kW
- Dyness Batteries DH200Y: 4×232 kWh cabinets and 4xPCS 100 kW
- Cooling: Liquid cooling
Smart energy management system (EMS):
- Full integration and control of the PV and the battery storage systems;
- Optimization according to usage demand and market prices (price tariffs: segment “Day ahead”);
- Integration of a smart energy management system that can work with predefined scenarios;
- Option for future integration of an EV charging stations.
Benefits:
- Minimizing the energy costs;
- Load shaving;
- Arbitrage;
- Smart production, storage and load control.
