Features
8.1 Protection
Q.HOME Core has the following protective features to prevent equipment and persons from being
damaged due to external accidents or equipment failure:
• Short circuit protection
• Over voltage / over current
• Over temperature
• Insulation resistance surveillance
• Residual current protection
• Anti-islanding protection
8.2 Power Derating
Q.HOME Core limits the output power on over-temperature
to protect the inverter from overload or other potential
errors. If the temperature does not drop beyond a certain
period, the inverter stops its operation.

8.3 Power Quality Response
•
Active Power Response
:The inverter supports the active power response mode according to the
grid code to support the grid system.
- Volt-Watt : The input and output active powers are limited by the response curve according
to the inverter operation mode (charging and discharging) and the grid system voltage. This
response is supported only in Australia and New Zealand.
