Description
xPylontech 219kWh A300 Commercial Hybrid Battery Energy Storage
The Pylontech A300 219kWh is a complete commercial battery storage system supplied as a factory-assembled cabinet. It is designed for businesses that need to cut electricity costs, make better use of solar generation, and maintain reliable power during grid outages or peak demand periods.
The system arrives pre-built and ready to connect, which reduces installation time and complexity compared with building a large battery system from individual components on site. It can be configured with one or two hybrid inverters depending on the site power requirement, charge rate and backup capacity needed.
Key Features
- 219kWh LFP battery capacity in a single factory-assembled cabinet
- Available with 1 or 2 hybrid inverters to match site requirements
- IP55-rated outdoor enclosure with integrated active cooling
- Integrated EMS for intelligent charge and discharge management
- Built-in fire protection and battery management system
- Supports solar self-consumption, peak shaving, electricity arbitrage and grid backup
- Suitable for commercial, industrial, agricultural and EV charging sites
Product Overview
At 216kWh, this system provides a substantial energy reserve for sites with significant daily electricity consumption. Energy is stored when solar production is high or when import tariffs are lower, then discharged during expensive peak periods or when the grid is unavailable. The result is lower electricity bills and greater resilience against supply interruption.
The single inverter configuration suits most standard commercial storage and solar self-consumption applications. The dual inverter option is better suited to sites with higher peak loads, faster charging requirements, or where stronger backup capacity is needed for critical circuits.
All battery modules, BMS, cooling, safety protection and energy management are integrated and factory tested before delivery. There is no need to source, size and wire individual components on site.
Applications
- Commercial premises: offices, warehouses, factories and retail sites
- Agricultural sites and farms with solar PV
- EV charging hubs requiring grid buffering or off-peak charge storage
- Industrial sites with high peak demand requiring load smoothing
- Microgrid and partial off-grid commercial installations
- Sites requiring long-duration backup for critical loads
Installation Notes
This system must be installed by a qualified electrical engineer with experience in commercial battery storage. Site assessment, load analysis, grid connection compliance and commissioning must be completed by a certified installer. Contact us to discuss project requirements, inverter configuration and site suitability before ordering.
