[QUOTE="johnb2713, post: 545580, member: 35153"] You could try a meter in place of the CT, that may improve things at the low import / export levels but it may be at a cost in response times to a step change in load eg and immersion heater switch on/off. It is possible that youre in the zone of operation where the steps in voltage arent fine enough to really trim the import / export to zero. To truly get away from this situation, remove the grid tie and run your load from the inverter directly, importing from the grid to charge batteries only if necessary. [/QUOTE]
