About The output current of photovoltaic inverter is too high
By UL 1741 requirement, grid-interactive inverter AC output current may not exceed the maximum current rating in the inverter's specification, regardless of the total DC power available. This in turn limits the DC input current.

Check if the grid voltage on the inverter is present. If not, check for the absence of grid voltage on the supply point. If present, but too high, or too low, contact the operator to change the grid’s parameters. Contact ABB customer service if the grid voltage and frequency are within the inverter’s range. W009: Empty Table.
Two strings into the inverter, both showing high volts (PV1, PV2) with fault code shutting down inverter. Each string usually showing circa 250v DC, now high DC error with 600v at each string. Shaunb, did you ever find out the cause of this fault on your system?.
Error 51 - Inverter temperature too high A high ambient temperature or enduring high load may result in shut down to over temperature. Reduce load and/or move inverter to better ventilated area and check for obstructions near the fan outlets.

6 FAQs about [The output current of photovoltaic inverter is too high]
Why does my inverter keep shutting down?
Error 51 - Inverter temperature too high A high ambient temperature or enduring high load may result in shut down to over temperature. Reduce load and/or move inverter to better ventilated area and check for obstructions near the fan outlets. The inverter will restart after 30 seconds. The inverter will not stay off after multiple retries.
Why does the output voltage decrease when the inverter starts?
Some loads like motors or pumps draw large inrush currents in a start-up situation. In such circumstances, it is possible that the start-up current exceeds the over current trip level of the inverter. In this case the output voltage will quickly decrease to limit the output current of the inverter.
Can a solar inverter cause a fault?
Like any piece of equipment, solar inverters can experience faults and errors that can disrupt the operation of the solar system. In this section, we will discuss some of the common error faults that may occur in a solar system inverter in Australia.
What causes a power inverter to fail?
This can be a safety hazard as it may cause the inverter to feed electricity back into the grid, potentially leading to injury or damage. This error occurs when the inverter’s internal temperature becomes too high, which can be caused by a variety of factors such as a faulty fan or a blocked ventilation system.
What causes a solar inverter error?
Understanding the causes of these errors and how to troubleshoot and repair them is important for maintaining the efficiency and effectiveness of your solar system. This error occurs when the current flowing through the inverter is too high, and can be caused by a variety of factors such as a short circuit or a faulty solar panel.
Why is my PV inverter NOT working?
Check the PV array cabling and panel isolation, the inverter restarts automatically once the issue is resolved. The ground leakage current in the PV array exceeds the allowed 30mA limit. Check the PV array cabling and panel isolation. Check the installation and restart the unit using the power-switch.
