Frequently asked questions
Why does an on-grid solar system shut down during a power cut?+
This is a mandatory safety feature called anti-islanding. When the grid fails, the solar inverter immediately stops exporting power to prevent electrocuting DISCOM line workers repairing electrical cables down the street.
Can I add batteries to an on-grid system later?+
Yes, provided you install a hybrid-ready inverter during initial commissioning or install an AC-coupled battery storage retrofit later.
