What prepaid meter do you have which area are you in. chances are you hitting peak allocated amps from grid and prepaid meter is disconnecting for a short period. Or meter is picking up reverse current. if your non essential items, oven, geysers etc disconnects when the ac light goes off on inverter Its your prepaid meter supply and not the inverter thats causing it. (Not the control unit in the house.) most cui devices have a backup battery in it as well so the prepaid meter interface will have power for a while even when supply drops for a bit. if pushing back current to non essential load is getting incorrect readings from the CT the meter might be going into protection for a short period. Test by switching off solar inputs and time of use all at 100% Another way to test would be to switch off the geyser on the mains. Once loadsh1tting finishes. The time of use will pull power to charge batteries together with any non essential items and this might be too high draw for prepaid meter power allocated to you. some suppliers will give a code to enable higher peak draw. test non essential load and see that it matches the ct coil readings.eg. Use a hairdryer on non essential side and essential side and confirm power draw is showing on the inverter. And ct coil readings match up.
