BLUETTI EP800 + 3×B500 Residential Energy Storage System

Equipment Type and Primary Applications: Ground-mounted home battery backup engineered for grid outage resilience and photovoltaic load shifting. Performance Specifications: • Total storage: 14.8 kWh (three 4,960 Wh B500 modules) • Continuous AC output: 7,600 W pure sine wave, 120V/240V split-phase • Max solar input: 9,000 W DC • Utility transfer time: <20 ms • Housing standard: NEMA 4X / IP65 Safety Features and Certifications: LiFePO₄ chemistry prevents thermal runaway and hazardous gas emission. Internal BMS enforces overvoltage, undervoltage, and short-circuit cutoffs. Designed to align with UL 9540 residential ESS safety protocols. Installation and Maintenance Requirements: Level components on the enclosed trolley. Terminate utility, PV, and load circuits via the included harness. Commission via Bluetooth app pairing and breaker sequence verification. Inspect wiring strain relief and terminal torque every four months. Maintain ambient operation between 0°C and 40°C. Warranty and Service Information: Decade-long coverage applies to the EP800 inverter. Five-year protection guards battery modules against capacity decay below 60%. Remote diagnostic logs enable expedited replacement dispatch and technical troubleshooting. Branding/References: Manufacturer: BLUETTI. Core model: EP800 Hybrid Inverter paired with three B500 packs. Consult EP800 wiring diagram and B500 spec sheet for compliance verification. Differentiators: Dual-inverter parallel architecture scales continuous delivery to 15,200 W while maintaining identical waveform phase alignment, eliminating voltage collapse during concurrent motor startup loads.
