PV and BESS systems integration

Client: M.J.Dairies

Project: Milk Processing Plant

Site information: A production facility with an approximate area of 21,000 m²

Location: Karlovo, Bulgaria

Scope: PV 600 kW | BESS 1290 kWh

Year: 2025

Project description:

A production facility with an existing photovoltaic installation for own supply with a capacity of 725 kWp.
The plant has a constant consumption 24/7 and with almost no surplus of the produced energy.
The goal of the project is to increase the capacity of the PV installation and to add a high quality battery in order to store the the increased amount of energy produced.

PV Installation:

  • Peak Power: 600 kWp (additional to an existing PV installation with a peak power of 725 kWp)
  • Inverters: 5 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 DH200F: 6 x 215 kWh cabinets and 6 x PCS 100 kW

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 to use the BESS as an emergency power supply.

Benefits:

  • Minimizing the energy costs;
  • Peak shaving;
  • Arbitrage;
  • Smart production, storage and load control;
  • Optional emergency power supply.
