Solar Power Plant of ZAC Mitra

The ePowerControl MC was selected as the EMS for Daher
Foods in Lebanon, as part of a solar photovoltaic and
10Mwh BESS project installed and commissioned by
ASACO General Trade & Contracting, serving as the project’s
EPC. Elum’s solution coordinates the PV plant, BESS, grid,
and gensets to ensure a reliable power supply and optimize
energy efficiency. The plant primarily operates off-grid,
with the flexibility to switch to grid-connected operation
depending on the battery’s state of charge.

In BESS Prime mode, the PCS operates in grid-forming
mode, regulating system voltage and frequency. The
gensets can start in grid-following mode, synchronizing
with the PCS and following load demand while the battery
continues to discharge. If the gensets cannot be started in
PQ mode based on the configured battery SoC thresholds,
an additional plant-level SoC threshold acts as a fallback,
triggering a transition to Genset Prime mode. The genset
then takes over grid-forming control until the configured
stop SoC is reached, allowing the plant to return to BESS
Prime mode. The Virtual Synchronous Generator (VSG)
functionality also supports battery SoC equalization.

In Grid Prime mode, the grid supplies power while the PV
and BESS operate in grid-following mode, enabling solar
optimization, peak shaving, and power factor control.

ePowerMonitor Pro provides centralized monitoring of key
plant metrics, equipment health, and operational
performance.
