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.

The distance between the inverter and smart meter is suggested sless
than 100M. For the distance more than 100M, it needs to parallel a
120Ω resistor between 24A and 25B of the 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
time, it can only be pressed intermittently, otherwise the meter will be
locked.
