CT Innacuracy
I've recently installed a SS 3.6 inverter and just added a 5kwh battery. I'm having issues with the inverter discharging the battery overnight and looking into it I think I have an issue with the CT coil.
Using another CT monitor the import is around 260W, yet the inverter is reporting 10W. My CT is around 15m from the consumer unit, and extended with shielded twisted pair cable. Is there any way of compensating for this or adjusting somehow?

Thanks Groot. Seems like I've fixed one issue with the CT cable not being extended correctly (I'd not used the twisted pairs properly). I'll monitor tonight to see what happens and post up results. The Tuya monitor does take a mains feed and seems to account for actual voltage when calculating power. Both CTs are pretty similar now in measurements so I hope this was my issue.
