20kW LiFePO4 Lithium Battery Solar Generator 580-740W Bifacial PV Panel 230V

The TIANON ESS03 is a high-capacity 20kW LiFePO4 lithium battery solar generator system designed for residential home backup and off-grid power applications. Combining 580-740W bifacial half-cut monocrystalline PV modules with advanced MPPT charge control and long-cycle LiFePO4 battery storage, the ESS03 delivers clean, silent, and maintenance-free electricity for whole-home use. Each PV module measures 2279×1134×30mm and weighs 31kg, with a 43.03V / 13.96A MPP rating for maximum energy harvest. The system provides 230V/380V output at 50Hz/60Hz with 24-hour continuous operation, making it an ideal replacement for diesel generators in residential settings. All components—including PV1-F 4mm² DC cables and BIPV mounting hardware—are supplied as a complete kit from a single manufacturer. CE, IEC, MSDS, and UN38.3 certified for international trade and safe transport.

1. How does this compare to a diesel generator? - The ESS03 produces zero emissions, zero noise, and requires no fuel deliveries or engine maintenance. While the upfront cost may be higher, the lifetime operating cost is significantly lower with free solar fuel and minimal maintenance.
2. What appliances can the 20kW system power? - A 20kW system can simultaneously run refrigerators, freezers, well pumps, lighting, HVAC systems, washing machines, and kitchen appliances for a typical large family home.
3. How long does the battery last during an outage? - Battery runtime depends on your load and battery bank size. Contact our engineering team for a customized sizing calculation based on your specific energy consumption profile.
4. Is professional installation required? - While the kit includes all components and detailed documentation, we recommend professional installation by a qualified solar electrician to ensure optimal performance and warranty compliance.
5. Can the system be shipped internationally? - Yes, all components are UN38.3, MSDS, and Dangerous Goods certified for safe sea and air freight worldwide. We handle all export documentation.
