Introduction The SU50 Stationary Energy Storage System Unit provides state-of-the-art battery energy to commercial customers in an easy-to-install and commission package. The system provides 50 kw output to perform building demand Peak Shaving using Model Predictive Control to learn and predict the building demand. The system can be ordered with enough capacity to provide a continuous 50 kw output for 1, 2, 3, or 4 hours. Figure 1: L2000 SU50 Stationary Energy Storage System Unit The SU50 system is packaged to be installed quickly by a trained electrician. The system has skid mounting for easy placement with a forklift, preinstalled battery modules, and a single electrical interconnection point. The SU50 system can be monitored, controlled, and integrated into the energy control system of a facility and fully supports the California Self-Generation Incentive Program (SGIP) and Hawaii Rule 14 requirements. The SU50 can be easily configured to update tariff and energy rates remotely. It can also monitor performance and economic savings via a web interface. There are three applications for the SU50. Embedded Model Predictive Control (MPC) Demand Management uses machine learning to minimize energy costs. It dynamically learns and predicts your facility load, then cooptimizes both load shifting and peak shaving to optimally control charge and discharge schedules for maximum economic benefit. 3
Solar + Storage allows the battery to be charged by solar to get tax credits. It also allows the storage to be dispatched to reduce customer demand charges. Backup Power is an effective application for the SU50. The SU50 can serve as a reliable source of backup power if there is loss of power from the grid due to severe weather conditions or other issues. By helping facilities remain operational, the system allows our customers to eliminate the costs of downtime. The system can be configured anywhere from 1-4 hours of backup. Features and Benefits Everything in One Box A single package contains the 50 kw inverter, batteries, Emergency Power Off (EPO) switch, application controls and meter. Quick Installation Place the skid-mounted system on a concrete pad, stone, or the ground, for quick installation by an electrician. Connection requires only a single grid point and an internet connection. Easy Commissioning Once the SU50 is connected, the system learns the facility operation and starts the application, whether it s demand management and peak shaving or integration with a solar PV system. Seamless Compatibility Use standard protocols for easy integration with your building management system, making it easy to view energy storage alongside other building systems. Remote Monitoring and Control Stay on top of performance and savings with local and remote real-time monitoring, diagnostics and control including easy updates for tariff and energy rates. Minimized Energy Cost Embedded machine learning via model predictive control predicts facility load, then optimizes the application for maximum economic benefit. The SU50 system meets California Self-Generation Incentive Program (SGIP) and Hawaii Rule 14 requirements. Flexible Applications Use for peak shaving, solar + storage, and other applications and as a backup power source to continue operations during a grid outage. 4
