Description Key Features True All-in-One Design: Combines the Power Conversion System (PCS) and Battery PACK into a single, compact footprint (650*2050*700mm). This drastically reduces installation time, labor costs, and saves valuable space in your garage or utility room. Massive Built-in Capacity: Equipped with high-grade 51.2V 200Ah LiFePO4 modules. The ESP-5010 offers a staggering 51.2kWh, while the ESP-4020 delivers 40.8kWh of energy, providing days of backup power for a standard home during grid outages. Heavy-Duty Hybrid Inverter: Features a robust single-phase inverter (10KW or 20KW) with dual MPPT trackers (Max 500V DC input), supporting seamless transitions between on-grid savings and off-grid independence. Industrial-Grade Expansion: The advanced control system allows up to 10 units to be connected in parallel on the AC side, enabling massive capacity and power scaling for Commercial & Industrial (C&I) projects. Intelligent Thermal Management: A built-in smart cooling system actively regulates internal temperatures, ensuring optimal performance under heavy loads and extending the battery cycle life to ≥6000 cycles. Rugged IP54 Protection: The fully sealed enclosure is IP54 rated against dust and moisture, with optional C3/C5 anti-corrosion upgrades available, making it highly resilient in demanding environments. Comprehensive Warranties: MUST stands behind this premium system with a 5-Year Warranty on the Inverter and a 10-Year Warranty on the Lithium Batteries. Applications Luxury Residential Backup: A single unit provides enough power and storage to run whole-house loads, including heavy appliances, entirely off-grid. Small Commercial (C&I): Ideal for offices, retail stores, and workshops to maximize solar self-consumption and eliminate peak demand charges. Microgrids: The massive parallel capability makes it the perfect foundation for community or farm-scale solar microgrids.
