If the remote monitor displays no output voltage for your SolaX Power Inverter, the output switch may be tripping. Check if the DC switch is damaged, and if not, switch it to ON. If it still doesn’t work, contact your dealer.
What to do if SolaX Power X3 displays 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 high residual current. If this occurs once, it might be due to a temporary external circuit issue, and the inverter should return to normal after the fault is cleared. If it happens repeatedly or persists, check the insulation resistance against the ground of the PV strings.
Why SolaX Power X3 is off grid?
Your SolaX Power Inverter might be off-grid due to a power grid fault or a tripped DC switch. Wait for the power to be restored. Also, turn the DC switch to the ON position.
What to do if SolaX Power Inverter shows PV Over Voltage?
If your SolaX Power Inverter shows a 'PV Over Voltage' error, it means the input voltage from the PV modules is too high. Check the number of PV modules connected and adjust as needed.
What to do if SolaX Power Inverter displays PV Strings Abnormal?
If your SolaX Power Inverter displays a 'PV Strings Abnormal' message, it could be because the PV strings have been shielded for an extended period or are deteriorating. First, check if the PV string is shielded. If the string is clean and unshielded, inspect the PV modules for signs of aging or deterioration.
What causes BUS Under Voltage on SolaX Power X3?
A BUS Under Voltage error on your SolaX Power Inverter 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 can automatically recover to normal operation after the fault is rectified. If the alarm occurs repeatedly, contact your dealer for technical support.
What does Insulation Resistance Abnormal mean on SolaX Power X3 Inverter?
An 'Insulation Resistance Abnormal' error on your SolaX Power Inverter indicates a short circuit between PV strings and the protection ground, or that the PV strings are installed in a long-term moist environment. Check the insulation resistance against the ground for the PV strings. If a short circuit has occurred, rectify the fault. If the insulation resistance against the ground is less than the default value in a rainy environment, set Insulation resistance protection on APP.
What to do for PV Under Voltage error on SolaX Power Inverter?
A PV Under Voltage error on your SolaX Power Inverter indicates that the PV modules input voltage is below the inverter’s defaulted protection value. When sunlight intensity weakens, PV modules voltage decreases, which requires no action. If this occurs when sunlight intensity does not weaken, check if there is a short circuit or open circuit in the PV strings.
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.
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.
