Do you need a solar inverter?

Without a solar inverter, the electricity generated by the solar panels would be useless for powering appliances and devices. There are several types of solar inverters available on the market, including grid-tie inverters, off-grid inverters, and hybrid inverters.

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.

How do I know if my inverter is communicating?

A steady blue light indicates the inverter is communicating. Connect to the device using SetApp. Navigate to Monitoring Communications. This page shows the current connection status. Use the Troubleshooting section in this guide to identify any steps needed to help resolve the communications issue.

How do I know if my inverter is producing power?

For more information regarding your system’s production and communication, please follow the steps below. Please note: The system doesn't produce at night time. Look for the green LED: when it is on, the system is producing power, if it is flashing, this means the inverter has AC power and is in Standby mode.

What happens if an inverter is undervoltage?

For undervoltage errors, an inverter repairer will need to check the condition of the battery and replace it if necessary. If the battery is in good condition, they check the panel’s connections to ensure that they are secure and not damaged.
