Greenrich WM5000 4.95kWh 51.2V LiFePO₄ 1.5C Wall-Mount Battery

The Greenrich WM5000, also known as the AW7500 wall-mount battery, is a premium low-voltage lithium energy storage solution designed for residential and small commercial solar systems that require higher instantaneous power delivery. Built using lithium iron phosphate (LiFePO₄) cell technology and a high-current battery management system, the WM5000 is engineered to carry heavy household loads with confidence.

This battery is specifically designed for wall-mounted installation and is ideal for installations where floor space is limited but performance requirements are high.

System Role and Ideal Applications

The Greenrich WM5000 is designed to store solar energy and supply power during load shedding, grid outages, or peak demand periods. Its high 1.5C discharge capability makes it particularly suitable for homes running multiple appliances simultaneously, including kettles, ovens, pumps, air conditioners, and other high-draw loads.

Typical applications include residential hybrid inverter systems, backup power installations, and modular battery banks where higher power output is required without moving to high-voltage battery platforms.

51.2V Low-Voltage Battery Architecture

Operating at a nominal voltage of 51.2V, the WM5000 fits into the standard low-voltage lithium battery class used by most residential hybrid inverters. This voltage range offers a strong balance between safety, efficiency, and broad inverter compatibility, while still enabling substantial power delivery.

LiFePO₄ Cell Technology and 1.5C Performance

The WM5000 uses LiFePO₄ cells known for their thermal stability, long cycle life, and consistent voltage output. What differentiates this battery from standard 5kWh units is its 1.5C continuous discharge capability, allowing it to deliver up to 7500W of power continuously.

This higher discharge rate allows the battery to support demanding loads more effectively than conventional 1C batteries, particularly during peak usage periods.

Smart BMS and Electrical Protection

An integrated smart Battery Management System continuously monitors voltage, current, temperature, and state of charge. Protection features include under-voltage and short-circuit protection, low and high temperature charge protection, low and high temperature discharge protection, charge and discharge over-current protection, and a dormancy function.

These protections ensure safe operation and long-term battery health under daily cycling conditions.

Inverter Communication and Compatibility

The Greenrich WM5000 supports communication via CAN, RS485, and RS232, allowing direct integration with a wide range of compatible hybrid and inverter-charger platforms. Proper communication enables coordinated charge and discharge control and improved system efficiency.

Wall-Mount Installation and Physical Design

The battery is designed as a wall-mount system, allowing neat and space-efficient installation. Its slim profile and metal enclosure make it suitable for installation in utility rooms, garages, or dedicated battery spaces, provided the environment is dry and well ventilated.
