I brought a Iammeter for my Solax Inverter and all reads correct with consumption and export, but when I use the Iammeter app for android and the Iammeter web login  I am finding that the consumption and export reading is opposite are totally the other way, what has gone wrong?

Hi:

For some reason ,the requirement of CT installation direction is different between solax-portal and IAMMETER.
In solax portal ,it need the K-L direction of CT is point to the main breaker. But in IAMMETER ,the direction is on the contrary.

This ”different installation requirements “ make you can not use solax-portal and IAMMETER simultaneously.
