Description
This bundled system combines the EG4 12000XP off-grid hybrid inverter with a single 14.3 kWh Indoor Walmount 48V 280 Ah EG4 lithium battery to create a compact, high-performance power stack for whole-home backup, partial off-grid operation, or daily solar cycling.
The 12K-XP delivers true split-phase 120/240 VAC output, fast transfer speeds, generous solar input capacity, and closed-loop battery communication for precise charging and state-of-charge management. Paired with the ~14.3 kWh 280Ah LiFePO₄ battery, this system offers deep, long-life storage in a clean, serviceable wall-mount format.
Designed with installers in mind, the inverter supports high-voltage PV strings via dual MPPTs—often eliminating the need for external combiners—while front-access breakers and clearly labeled terminals simplify commissioning. The battery’s integrated DC breaker, LCD display, and communication ports make diagnostics, maintenance, and future expansion straightforward. Start with one battery today and scale later without re-engineering the system.
Product Details
All-in-One Power Backbone
A 12KW split-phase inverter/charger capable of supporting large residential loads, with rapid transfer, grid or generator input, and closed-loop communication to EG4 batteries. Parallel-ready for future system growth.
Large PV Headroom
Dual MPPT charge controllers (two inputs each) allow up to ~24 kW of DC solar input. The wide PV voltage window simplifies string design, reduces balance-of-system components, and supports modern high-voltage arrays.
Robust Lithium Storage
A 48V 280 Ah (≈14.3 kWh) LiFePO₄ battery with advanced BMS protection, cell-level monitoring, and long cycle life. Front-mounted controls and display enable quick diagnostics and safe servicing.
Installer-Friendly Design
Front-service breakers, clear clamp zones, and labeled landings reduce install time. CAN and RS-485 closed-loop support ensures accurate SOC reporting and charge/discharge limits.
Clear Growth Path
Begin with one 280 Ah battery for essential backup or daily cycling. Add additional battery modules—or parallel inverters later—to increase runtime, surge capability, and overall system capacity as energy needs grow.
