AcuDC 240 Overview
What is DC Energy Metering?
DC metering is used in specific applications to measure, collect, and store real-time data for DC power systems. Energy professionals use DC meters to monitor power generation, power usage, or to detect system faults to meet specific performance goals, reduce cost, or to verify energy integrity in their facility. It is used in various industries such as solar systems, EV charging stations, battery energy storage systems (BESS), cell towers, data centers, and light rail transportation.
