1.2kW 4kWh All In One LiFePO4 Solar ESS Off Grid Home Solar Energy Storage Kit -

The Tianon P003 is a fully integrated all-in-one energy storage system that combines a 1.2kW pure sine wave inverter, a robust 4kWh LiFePO4 battery, and an 800W MPPT solar charge controller into a single compact floor-standing unit. Designed for modern residential needs and small-scale off-grid applications, this plug-and-play system eliminates the complexity of separate components and professional installation. Built with genuine Grade A Lithium Iron Phosphate cells, it delivers clean 230V AC output for sensitive electronics, while the built-in MPPT maximizes solar harvest. The intuitive central LCD display provides real-time monitoring of AC/PV input, battery SOC, and load consumption. With 6,000+ deep cycles at 25°C, -10°C discharge resilience, and a 10-year factory warranty, the P003 is the definitive integrated solution for small homes, cabins, garden offices, and emergency backup scenarios.
