28kWh Home Battery System Successfully Deployed in Vietnam

In December 2025, GSL ENERGY completed the delivery and deployment of a 28.68 kWh home energy storage system in Vietnam. The project utilizes two parallel-connected 14.34 kWh floor-standing LiFePO4 energy storage batteries to create a whole-home energy storage architecture, providing the local customer with long-term, stable, and expandable home energy management capabilities.

Vietnam is one of the fastest-growing photovoltaic and energy storage markets in Southeast Asia. Continuously rising electricity prices and frequent grid fluctuations in both urban and rural areas have made residential-level Lithium Battery Energy Storage Systems (BESS) a crucial investment for users seeking to enhance power security and energy independence.

1. Vietnam's Home Energy Profile: High Heat & Humidity + Urban/Rural Grid Instability

User research conducted by GSL ENERGY across multiple provinces and cities in Vietnam revealed:

Summer peak loads lead to frequent short-term power outages and voltage fluctuations.

Electricity prices in towns and cities continue to rise, driving user interest in solar power to reduce costs.

The hot and humid climate places higher safety demands on energy storage equipment.

Limited space in residential homes requires compact energy storage configurations.

Based on these characteristics, the dual 14.34kWh floor-standing energy storage batteries (the Powerwall Floor-Standing Version) were selected as the core energy storage solution for this project.

2. System Configuration for This Project: Dual 14.34kWh Batteries + Hybrid Inverter

This floor-standing configuration is particularly well-suited to the installation features found in many Vietnamese homes, such as equipment rooms or balcony storage areas. It improves space utilization and enhances equipment cooling capacity.
