I already have a D103 energy monitor. Can I replace just the current transformers with larger ones?

No, D101/D103 energy monitors do not allow replacing only transformers with others.

All CTs are different and calibrated for a specific D101/D103 device to ensure high accuracy ±0.5% F.S.

Therefore, you should choose the right model right away.



Can the smart-MAIC D103 energy monitor be used in a Delta grid without a neutral wire?

No, the neutral wire is required to connect the D103 device as described in the instructions.
