In north-central Serbia, the land is flat and fertile, with a well-developed agricultural sector. Numerous crop and livestock farms rely on stable electricity to sustain their production. However, the local power grid faces issues such as unstable power supply and high electricity costs. Equipment like water pumps for sprinkler systems and temperature-controlled oxygen supply units often shut down due to power outages or voltage fluctuations, causing electricity troubles and production losses for the farms.
To address this pain point, Hua Power has deployed 30kW/60kWh user-side energy storage projects for 3 local farms. Leveraging its core technologies, the projects enable PV energy storage for self-consumption and off-grid backup power, meeting the farms' electricity needs.

In addition, the multi-unit parallel technology design reserves expansion space for the farms to scale up production and increase electricity load in the future.

During the project implementation, the Hua Power team provided full-process services. From the early-stage investigation of the farms' electricity needs, system scheme design, to equipment installation and commissioning, and training for operation and maintenance personnel, all processes were followed up by professional engineers to ensure the energy storage system was highly adapted to the farms' electricity usage scenarios.
After the project was put into operation, the electricity generated by PV panels is prioritized for powering the farms' equipment during the day, and the surplus electricity is stored in the batteries, maximizing the utilization efficiency of PV energy. When the PV power generation is insufficient, the energy storage batteries discharge to power the loads; alternatively, the system automatically switches to the municipal power mode. When the battery power is low, the municipal power fast charging function is activated to ensure the continuous operation of critical equipment such as water pumps for sprinkler systems.
