Export to the grid

If you don’t have an offtake agreement with your electricity retailer, your export will be limited to the lower of 5% of inverter capacity or 10 kW. We’ll confirm your final export limit as part of our assessment. Requests to export energy require additional checks, which may extend the overall assessment timeframe.
