Description
xOPTIM US A300 HY 216kWh Hybrid Energy Storage System
The OPTIM US A300 HY 216kWh Hybrid Energy Storage System is a complete commercial battery storage solution designed for businesses that need reliable power, reduced electricity costs and improved energy independence.
This system is supplied as a pre-made, factory assembled battery cabinet, making installation faster, cleaner and easier compared with a system built from separate components on site. It can be configured with 1 or 2 hybrid inverters, depending on the required site power, charge and discharge performance, and backup requirement.
Complete 216kWh Turnkey Energy Storage Solution
Built with advanced LFP lithium battery technology, intelligent energy management and integrated safety protection, the A300 HY is ideal for commercial and industrial applications where dependable power and long service life are essential.
The large 216kWh battery capacity provides a strong energy reserve for peak shaving, solar self-consumption, electricity arbitrage and long duration backup power. Energy can be stored when solar production is high or when electricity prices are lower, then used during peak tariff periods or grid outages.
Suitable Applications
- Commercial buildings
- Warehouses and factories
- Farms and agricultural sites
- EV charging locations
- Solar PV systems
- Microgrid and off-grid applications
- Backup power for critical loads
1 or 2 Hybrid Inverter Configuration
The OPTIM US A300 HY can be supplied with 1 or 2 hybrid inverters, giving excellent flexibility for different project sizes and site requirements.
- Single inverter configuration: suitable for standard commercial energy storage, solar self-consumption and backup applications.
- Dual inverter configuration: ideal for higher power sites requiring stronger backup capability, faster charging and greater peak load support.
Designed for Commercial and Industrial Environments
The system is housed inside a robust IP55 outdoor rated cabinet with controlled cooling, fire protection and smart monitoring. This makes it suitable for demanding commercial and industrial environments where safety, reliability and performance are critical.
