On-grid, or grid-tied, means the inverter can generate power when connecting to the grid. When the grid is disconnected or cut-off, the on-grid inverters will stop until the grid is back due to anti-islanding requirements.
We have single phase from 600W to 8kW, and three phase from 3kW to 150kW. For more details, please refer to this page: https://www.solaxpower.com/x1-boost
