A residential solar energy system integrates one Menred ESS LFP.1433.F unit, rated at 14.33kWh, connected in parallel to a single Deye hybrid inverter. This configuration provides a balanced capacity for households seeking reliable evening power and short-term grid-outage resilience.
The LFP.1433.F operates at a nominal 51.2Vdc, within 44.8–57.6Vdc, and is compatible with hybrid inverters up to 8,000W. It uses cobalt-free LiFePO₄ cells, certified to UN38.3/MSDS standards, with a cycle life exceeding 6,000 at 0.5C and 25°C (80% depth of discharge).
The battery management system supports communication via CAN or RS485 protocols. On the LCD touchscreen version, users can manually select from over 27 inverter brands—including Deye—to ensure protocol compatibility without external converters. Wi-Fi and Bluetooth connectivity enable remote monitoring of state of charge, cell voltage, temperature, and cycle count via a mobile application.
Physical dimensions are 900 × 400 × 260 mm, weight 115 kg, designed for floor installation. Operating temperature range is -10°C to +50°C for discharge, 0°C to +50°C for charge. IP21 rating ensures protection against solid objects larger than 12.5mm.
As a solar battery, it delivers stable voltage and current output suitable for lighting, refrigeration, and small appliances during non-sunlight hours. The system is modular: up to 16 units can be paralleled for larger deployments, reaching 229.29kWh. Standard warranty is 5 years, with a 10-year option available.
