1. About This Manual
2. Parameter
Afore smart meter is an intelligent control device, which is designed for
grid-connected inverters. Its main function is to measure the generation and
consumption, transmit the data to the inverter through RS485 communication, to
ensure that the generated power of the inverter is less or equal to the user’s load.
Achieve the purpose of no power feed into the grid.
This manual describes the installation, operation and maintenance of the
following Afore Smart Meter.

c. If the smart meter’s pin order is incorrect wiring, the Smart Meter and the
inverter Pac will display negative values.
Note:
Due to the fluctuation on the grid side, the data transition delay will
occur between smart meter and inverter. And the values displayed on
the smart meter and inverter will be different.
Note:
The button on the smart meter cannot be kept pressing for a long

b. If the inverter running parameter (Running Param) is not selected as “Afore3”
or faulty occurs to the communication line, it means the inverter and the smart
meter are not in communication, the active power on the smart meter is
displayed normally, while the power of the inverter (PGrid) is displayed as 0W.
a. If the inverter operation normally and the smart meter wiring correctly, the
phase active power value display on the smart meter will be synchronize with
inverter power (PGrid) value display.
