How It Works
-
Solar charging (normal day)
Solar panels charge the battery via the 50kW solar inverter system during low-tariff hours. -
Grid failure detected
The BESS disconnects from the grid in <20ms and powers your facility from the battery. -
Backup electricity delivered
Your critical loads run off the solar power backup system for hours — no generator noise, no fuel needed. -
Grid returns
The system automatically resynchronizes, recharges the battery from solar or grid, and resumes normal operation.
