Part 1 – Overview & Features

Product Introduction

The 6kW Vertical Stackable All-in-One ESS is a sleek, integrated energy storage system combining a 6kW hybrid inverter with a 51.2V LiFePO₄ battery (100Ah or 200Ah). Designed for residential and light commercial use, it powers household appliances such as TVs, air conditioners, and lighting — all from a single, space-saving vertical unit.

With its stackable, expandable design, you can start with 100Ah and add a second battery module later to double your capacity to 200Ah (10.24kWh). The system features a built-in BMSpure sine wave output, and multiple communication protocols for seamless integration with solar PV and grid power.
