Product Description

System Configuration & Integration
Our All-in-One Outdoor Energy Cabinet is a pre-integrated, utility-grade power solution engineered for simplicity and performance. The system's core components are seamlessly housed within a single, robust enclosure:
Unified Power & Storage Core: The system features a tightly integrated Power Conversion System (PCS) and a High-Voltage Battery Bank. This eliminates external compatibility issues and reduces installation time from weeks to days. Choose from a 105KW or 125KW bi-directional inverter, pre-synced with a scalable LiFePO4 battery for 215KWH, 233KWH, or 261KWH of usable energy.
Advanced Thermal Management: An integrated Liquid Cooling System ensures optimal temperature control for the battery cells. This technology maximizes cycle life, guarantees consistent performance even under peak loads, and enhances safety—all while operating quietly and efficiently.
Intelligent Energy Control System: At the heart of the system is a built-in Energy Management System (EMS). This smart controller autonomously manages energy flow, enabling peak shaving, time-of-use optimization, and backup power readiness without requiring complex external setups.
Rugged and Durable Cabinet: Every component is protected by an Outdoor cabinet with IP54 protection, designed to withstand harsh environmental conditions. The system arrives pre-assembled and pre-tested, offering a true "plug-and-play" experience for a fast and reliable deployment.

Smart & Automated Operation
Our all-in-one energy cabinet operates as an autonomous power hub. It intelligently shifts between three key modes to maximize savings and ensure reliability:
Solar Optimization: Directs solar power to your loads, storing excess energy and using it to shave costly peak demand.
Cost Arbitrage: Automatically charges from the grid during low-rate periods and powers your facility during high-cost hours.
Instant Backup: Provides seamless, uninterrupted power for critical loads within milliseconds of a grid outage.
