Project Overview

Wenergy successfully delivered a 3.612MWh commercial & industrial (C&I) battery energy storage project in Moldova, supporting local businesses in maximizing photovoltaic self-consumption while improving power reliability and operational flexibility.

Designed for PV-coupled applications, the system prioritizes self-generated solar energy consumption without exporting excess electricity to the utility grid. Through seamless on-grid/off-grid switching, the solution maintains continuous power supply during grid outages while allowing photovoltaic generation to remain operational, significantly improving energy resilience.
