Three Phase anti backflow energy meter
Why is energy saving sometimes limited？
This may be due to low daytime load no battery storage or incorrect installation.
Can it be used in rental properties？
Yes it is widely used for landlords to control and optimize energy usage.
Does this meter save electricity directly？
No it helps optimize solar usage but does not generate extra power.
What happens if CT direction is wrong？
The system may detect power incorrectly and reduce inverter efficiency.
Is it compatible with all inverters？
It supports most inverters with RS485 Modbus protocol but compatibility should be confirmed.
Can it work without CT？
Yes for small current systems direct connection is possible, larger systems require CT.
Where should the meter be installed？
It must be installed at the main grid connection point to measure total power flow.
What is the main function of this meter
It measures real-time power flow and works with the inverter to prevent electricity from feeding back into the grid.
