This is similar to what I worked out over the first three months I had this thing; however, the next 6 mths have changed my mind. If 03 is total used, then it would equal the sum of 15 and 21 - it did for 3 mths but now it is very different. 22 is not used. For the first few mths 04 and 16 appeared to both be solar exported, they were both the same value; however, they are now quite different so I am not sure anymore. If agl used this meter's reading for billing, one might get a better idea ...
