What are you asking? If it’s acceptable to you, then obviously the answer is ‘yes’. There’s an article in ‘Learn’ that gives the worst-case accuracy that you can expect, and what you’re seeing is a lot better than that. I recently tried to do a ‘Monte Carlo’ analysis of the input circuitry, reported here: OpenEnergyMonitor 9th of March 2018 meeting summary which seems to indicate that your particular set of parts have conspired against the rules of probability. 
If you’re using an emonPi/emonBase, you can tweak the scales = coefficients in emonHub to adjust the recorded data to agree with your inverter. But bear in mind that c.t.'s are inherently inaccurate at low currents.
