Range-extended Energy Storage System
- The range-extended energy storage system integrates energy storage equipment and diesel generators inside a single container.
►Overview
The range-extended energy storage system integrates energy storage equipment and diesel generators inside a single container. It reserves ports for PV power generation and installation space for charging devices, supporting multiple charging sources including photovoltaic power, diesel generation and municipal grid power. Adaptable to harsh grid conditions, it is widely used in peak shaving & valley filling, capacity expansion and off-grid power supply scenarios.
