To Next PageTo Next PageWhy is my SolaX Power Inverter off grid?
Your SolaX Power Inverter may be off grid due to a power grid fault or DC switch tripping. If it's a power grid fault, wait until power is restored. If it's due to the DC switch tripping, turn the DC switch to the ON position. If the DC switch trips frequently, contact your dealer.
What to do if SolaX Power Inverter shows Residual Current Abnormal?
If your SolaX Power Inverter displays a 'Residual Current Abnormal' message, it means the insulation resistance against the ground at the input side has decreased, causing excessively high residual current. If the alarm occurs accidentally, it's possible the external circuits are temporarily abnormal; the inverter should automatically recover once the issue is resolved. However, if the alarm occurs repeatedly or lasts a long time, check whether the insulation resistance against the ground of PV strings is too low.
Why does my SolaX Power X3 Inverter show a Grid Over Voltage error?
A Grid Over Voltage error on your SolaX Power Inverter indicates that the grid voltage is exceeding its allowable range. If the alarm occurs accidentally, it is possible that the power grid is experiencing a temporary abnormality and no action is needed. However, if the alarm occurs repeatedly, contact the local power station. After receiving approval from the local power bureau, revise the electrical protection parameters setting on the inverter through the APP. If the alarm persists for a long time, check whether the AC circuit breaker/AC terminals are disconnected or if the grid has a power outage.
What to do if SolaX Power X3 shows Grid Over Voltage?
If the 'Grid Over Voltage' alarm appears on your SolaX Power Inverter, it could be due to the grid voltage exceeding its normal range. If it happens once, it may be due to a temporary grid abnormality and requires no action. If it happens repeatedly, contact your local power station and, with their approval, adjust the electrical protection parameters on the inverter using the mobile app. If the alarm persists, check the AC circuit breaker and terminals to ensure they are connected, and verify that the grid has power.
What to do if SolaX Power X3 displays PV Strings Reverse?
If your SolaX Power Inverter shows 'PV Strings Reverse', it means the PV string cables were connected incorrectly during installation. Check the PV string cables and reconnect them correctly if they are reversed.
What to do if SolaX Power Inverter displays no output voltage on the remote monitor?
This is caused by the output switch tripping. Check if the DC switch is damaged, and if it isn't, switch it to the ON position.
Why SolaX Power Inverter shows Zero power generation and Yellow alarm light illuminating in remote monitor system?
This issue is caused by a communications outage. If you're using a modem or other data logger, try rebooting it.
What to do if SolaX Power X3 shows BUS Under Voltage?
If your SolaX Power Inverter displays a 'BUS Under Voltage' alarm, it indicates an abnormal internal energy control imbalance, triggered by sharp changes in PV strings or grid working conditions. If the alarm occurs occasionally, the inverter should automatically recover.
What to do if my SolaX Power X3 Inverter's remote monitor displays zero power generation?
This issue is caused by a communications outage. If you're using a modem or other data logger, try rebooting it.
What to do if SolaX Power X3 shows PV Under Voltage?
If your SolaX Power Inverter shows 'PV Under Voltage', it means the input voltage from the PV modules is below the inverter's protection value. This can happen when sunlight is weak, in which case no action is needed. However, if it occurs when sunlight is strong, check for short circuits or open circuits in the PV strings.
