In this real-world installation, we showcase a powerful solar energy storage system featuring MENRED ESS LFP.6144.G4 lithium iron phosphate (LiFePO4) batteries and the DEYE SUN-14K-SG01LP1-EU hybrid inverter. This setup is designed to maximize energy independence, reduce grid reliance, and provide reliable backup power for a commercial property.
The system includes 2 sets of MENRED ESS LFP.6144.G4 batteries, totaling 49.14kWh of storage capacity. Each LFP.6144.G4 unit consists of 4× LFP.6144.G modules, each providing 6.144kWh, and comes with a control box for seamless integration and monitoring. With a 95% depth of discharge (DoD), these batteries ensure maximum usable energy, outperforming traditional batteries that often limit DoD to 50-80%. The compact design (600×1870×220mm) and stackable configuration allow for easy installation and scalability, supporting up to G8 stacking for larger energy needs.
Paired with the DEYE SUN-14K-SG01LP1-EU hybrid inverter, this system delivers 14kW of continuous power and features 3 MPPT trackers to optimize solar energy harvesting with 99.9% efficiency. The inverter boasts a maximum efficiency of 97.6% and a European weighted efficiency of 96.5%, ensuring high performance in various conditions. It also includes advanced protection features such as islanding protection, DC reverse polarity protection, insulation resistance detection, surge protection, leakage current monitoring, and overcurrent/short-circuit protection.
The inverter operates in a wide temperature range of -40°C to 60°C (with derating above 45°C) and features IP65 protection for durability in harsh environments. Its smart cooling system keeps noise levels below 30 dB, making it suitable for both indoor and outdoor installations. With a wall-mounted design and compact dimensions of 464×798.4×300mm (excluding connectors and brackets), it is easy to install and integrate into existing setups.
This combination offers significant benefits, including 80% reduced grid reliance, €2,300 annual energy bill savings, and reliable backup power during blackouts. The property owner praised the system for its durability, low maintenance, and quick return on investment, stating that it paid for itself in under 5 years.
The MENRED ESS LFP.6144.G4 batteries and DEYE SUN-14K-SG01LP1-EU inverter represent a proven, scalable solution for solar energy storage, trusted by homes and businesses worldwide. If you’re looking to enhance your energy resilience and savings, this system is a reliable choice.
