Enphase Energy System with IQ Battery 5P Owner’s Guide
Your system has experienced a shutdown if it is no longer providing power to your home. System shutdowns may be caused
by failure of any external wiring or accessories of the system, by a failure of the wired communication systems, or any other
equipment failure related to the Enphase Energy System. Recovery steps following system shutdown vary depending on the
cause of the shutdown. If solar production and grid are available and the batteries still do not recover, restart the batteries
by cycling the DC switches on the IQ Battery 5P unit, see Reset the IQ Battery 5P using DC switch (on page 20).
System recovery after shutdown
If your Enphase App shows "Microinverters not reporting" or "Batteries not reporting", give the system up to 15 to 20 minutes
to recover on its own. The Enphase Energy System reconnects automatically and recovers from wired communications
failures. If more than 20 minutes have elapsed and you do not see communication established, contact Enphase Support.

Troubleshooting
G100 is a compliance requirement for the UK that ensures safety of the customer's grid connection as well stability of the
grid. The requirement asks for regulation of grid import and grid export power on the site.
• Grid import: This is the electricity drawn from the grid to supply home loads.
• Grid export: This is the surplus electricity from the solar PV system that is sent back to the grid.
As a requirement of UK G100 compliance, the Enphase system must stop solar production and battery operations if grid
import power or grid export power exceeds the power limit criteria.
There can be two types of violations:
