HumsiENK 5.12kWh Home Backup, 48V 100Ah Wall-Mount LiFePO₄ Battery Active Balancing + 8000W Hybrid Split Phase Inverter, 120/240V, 10000W MPPT, UL1741, Off-Grid Solar

• 【5.12kWh Home Backup with High-Power Inverter】This kit includes one 51.2V 100Ah wall-mount battery (5.12kWh storage) and one 8000W hybrid inverter (10000W surge) with native 120/240V split phase output. Perfect for running refrigerators, lighting, electronics, well pumps, and workshop equipment. Expandable to 76.8kWh with 15 parallel batteries and 48kW with 6 parallel inverters — start small and scale up as your needs grow. • 【Grade A Cells & 10-Year Lifespan】Engineered with premium Grade A+ LiFePO₄ prismatic cells, delivering over 6,000 deep cycles at 80% DoD — equivalent to 10+ years of reliable service. Built-in 100A BMS with 3A active balancing ensures consistent cell performance, effectively doubling cycle life while protecting against overcharge, over-discharge, short-circuit, and temperature extremes. IP54-rated all-metal housing ensures all-weather durability. • 【Space-Saving Wall-Mount Design】Compact wall-mount design (21.65" × 19.09" × 7.28") installs flush against any wall — keeping your floor space completely clear. Ideal for garages, basements, and utility rooms. Package includes all necessary mounting brackets, screws, and power cables for hassle-free DIY installation. 60% lighter and 30% smaller than lead-acid alternatives. • 【8000W Inverter: True Split Phase & ≤10ms UPS】8000W continuous / 10000W surge pure sine wave output with native 120/240V split phase — no transformer needed. ≤10ms automatic transfer switching keeps computers, routers, and medical devices online during grid failures. Built-in 10000W MPPT solar charge controller and 160A battery charger in a single 3-in-1 unit. UL1741 certified with 21 built-in protections. • 【Important Usage Note for 8000W Inverter】This single battery (100A BMS, ~110A protection) supports the 8000W inverter for most household loads and surge-start appliances (refrigerators, lighting, electronics, microwave, well pumps, garage tools). For sustained loads above ~5,500W (central AC + electric oven + heavy machinery simultaneously at full output), we recommend adding a second battery in parallel for uninterrupted full performance. Expand anytime — up to 15 batteries in parallel. • 【Smart Monitoring & Seamless Communication】Built-in Bluetooth APP and LCD touchscreen for real-time voltage, current, and capacity monitoring. Supports CAN/RS485 communication for seamless integration with major inverters — pre-tested with the 8000W inverter. Inverter features WiFi/Bluetooth dual connectivity for remote APP control, LCD display, 4 charging modes & programmable time-of-use scheduling.
