Abnormal meter reading might result from incorrect wiring, improper CT connection, inconsistent parameter settings and more of the meter.
Following are common problems with abnormal meter readings and methods to fix them.
For other situations, contact the distributor or SolaX after-sales service.
• The power reading of a phase is opposite to the actual power flow. For example, the actual power flow is importing 2 kWh, but the reading is exporting 2 kWh.
In this case, check whether the CT direction and current input and output wires are correctly connected. CTs on the bus line must point away from the grid to the
inverter or load.
• The reading is proportionally larger or smaller than the actual value. For example, the actual export power is 2 kWh, but the reading is 1 kWh. In this case, check whether the current ratio set on the meter corresponds to the CT specification. If not, see “Setting the transformer current and voltage ratio” to reset it.
