A residential solar energy system employs three Menred ESS LFP.1433.F units, each rated at 14.33kWh, providing a total capacity of 42.99kWh. This configuration demonstrates a practical energy storage battery solution for homes with higher daily energy consumption or extended backup requirements.
The system maintains a nominal voltage of 51.2Vdc across the parallel configuration, operating within 44.8–57.6Vdc. Each unit contains LiFePO₄ cells rated for over 6,000 cycles at 0.5C and 25°C with 80% depth of discharge, ensuring long-term reliability in daily cycling applications.
The three units are connected in parallel to a single inverter or multiple inverters depending on the system design, with proper current distribution and protection mechanisms. The battery management system handles cell balancing and communication via CAN or RS485 protocols, with touchscreen interface for local monitoring. Wi-Fi connectivity enables remote access to real-time data including state of charge, voltage, temperature, and cycle count.
This scalable architecture allows homeowners to start with one unit and expand as energy needs grow, with a maximum configuration of 16 units reaching 229.29kWh. The system supports typical household loads such as lighting, refrigeration, and small appliances, providing evening power and backup during grid outages.
Standard warranty is 5 years, with a 10-year option available. The compact design (900×400×260mm per unit) allows for flexible installation in utility spaces, while the 115kg weight per unit ensures stability during operation.
