October 14, 20214 yr Dear , I install a 1.5 KW on gird solar home system on the roof of a customer. but the load of the customer is very low. So How can I stop the power exporting from solar to grid by applying a external circuit.

If you don't want to back feed into the grid, just disconnect the system from the grid.
October 15, 20214 yr what is the brand model of inverter? some on-grid inverters have limiter functionality through use of external CT (current transformer). 46 minutes ago, Beat said: I don't exactly understand your question.

October 15, 20214 yr What is the inverter brand? If its solis or kodak or sunsynk then they have CT clamps that you must/can install and then set to limit the export to grid. Edited October 15, 20214 yr by WannabeSolarSparky

That would mean that if the grid goes off (load shedding) your inverter shuts off also - no current in the home? Why do you want to stop back feeding after having bought an on-grid system in the first place?
