•
For IQ battery 5P (IQBATTERY-5P-1P-NA), the battery's power activates the IQ Battery 5P's
LED-based DC switch. If the battery SoC is less than 2%, one may be unable to turn it on,
as the IQ Battery 5P (IQBATTERY-5P-1P-NA) turns on automatically when the battery's
state of charge is recovered after being connected to a generator.
Table 3. Number of batteries that can be recovered with a specific generator wattage.

NOTE Do not overload the generator. To ensure this, switch on the DC switches in IQ Batteries
:
based on IQ Battery power and generator ratings. The total energy required for the number of
batteries charging must be less than the generator's output power.
•
The LEDs on IQ Battery units pulse softly green when charging with the DC switch on.
To verify that the batteries are charging, a current clamp multimeter can be connected
to the L1 or L2 wires from the IQ Battery and landed in the IQ System Controller.
•
The batteries may take up to 20 minutes to start charging initially, and the charging rate
may be low. The charging rate will increase once the batteries have recovered to more
than 2% SoC.
•
If the batteries are still not charging after 20 minutes, as per the procedure described
above, then contact
connection (aka tunnel) to the Gateway so that Enphase Support can make the
appropriate changes to the system and enable the batteries to charge.

State of charge recovery for an Enphase Energy System
WARNING: Only allow battery quantity per the specified table to be switched
on; switch off the remaining batteries to avoid overloading the generator.
Disconnecting all the batteries physically and only connecting those
intended explicitly for recovery is recommended.
