Technical FAQs for Outdoor Energy Storage

Yes. The enclosure is IP55-rated with C5-grade anti-corrosion coating. It is specifically engineered for high-salt, high-humidity, and dusty environments without needing additional roofing or shelters.

Yes. Every unit is a fully integrated system containing the Battery String, BMS, 105kW PCS (for the 215kWh model), and Smart EMS. It arrives pre-configured for immediate grid connection.

We use Grade-A LiFePO4 cells rated for >6,000 cycles at 80% DOD. Under standard C&I operating conditions, this provides a reliable design life of 15+ years.

The system is deeply compatible with mainstream hybrid and string inverters, including Deye, Growatt, and Megarevo. It supports both AC-coupled and DC-coupled micro-grid applications.

You need a level concrete foundation capable of supporting the unit’s weight (approx. 1.7 – 3 tons per cabinet). We provide full structural drawings and cable entry specifications to assist your site preparation.

For a 500kW load, we typically recommend 3 to 4 units of the 215kWh cabinet to balance discharge power and energy duration. Our engineers can provide a custom ROI and capacity layout based on your specific electricity bill.
