To be able to measure the energy out from a Solar Panel a meter needs to be able to do Four Quadrant Calculation.
This means it is capable of Identification of imported and exported active and reactive energy allows you to monitor energy flow in both directions: delivered from the utility and produced on-site.
In the iEM3000 series the following meters are capable of Four Quadrant Calculation.
iEM31** range - iEM3135, iEM3155, iEM3165, and iEM3175
iEM32** range - iEM3235, iEM3255, iEM3265, and iEM3275
iEM33** range - iEM3335, iEM3355, iEM3365, and iEM3375
iEM34** range - iEM3455, iEM3465, iEM3555, and iEM3565
