System information
IQ Battery 5P stores energy and dispatches it when
you need it. IQ Battery 5P is built on a distributed
architecture platform. This modular design means you
can quickly and easily expand your system as your
needs grow.
IQ Battery 5P
The Enphase App is a mobile app where you can monitor
and control your system status from wherever you
are and know exactly how much energy your solar PV
system is producing. You can generate reports on energy
production by day, week, month, or year.
Enphase App
Under each solar panel lies an Enphase microinverter that
converts DC power generated by the panel into AC power
that your home can use.
IQ Microinverters
The brain of the Enphase Energy System is Enphase
IQ Gateway. The IQ Gateway collects production and
performance data from IQ Series Microinverters and IQ
Battery 5P, manages your system, and communicates
with the Enphase cloud.
IQ Gateway
Key components
Current Transformers measure the current owing
through the system. The Enphase Energy System uses one
CT to measure the solar power generated on your roof
and one CT to measure the electricity consumption of
your entire home. These currents measured are fed to the
IQ Gateway.
Current Transformers
An accessory used to enable communication between IQ
Battery 5P and IQ Gateway. This device connects to IQ
Gateway via USB cable and IQ Batteries are connected to
this device via control cables.
Communications Kit
7
Enphase Energy System with IQ Battery 5P Owner’s Guide
IQ Battery 5P is an AC-coupled storage system with an energy
capacity of 5.0 kWh. It houses two major components inside
the cabinet which make the IQ Battery 5P powerful and
reliable:
• The battery packs, internal to IQ Battery 5P, store energy
for later use, such as night-time or lower solar production
circumstances. IQ Battery 5P can supply up to 3.2 kVA of
power to the loads in your home.
• The IQ Microinverters, internal to IQ Battery 5P, convert
stored DC energy into usable AC electricity for your home,
ensuring reliable power supply by sharing the load.
IQ Battery 5P communicates through wired communication to
the Communications Kit that then communicates through USB
to the IQ Gateway.
IQ Gateway collects production and performance data
from your Enphase Energy System. It then transmits the
data to the Enphase Cloud through Ethernet or Wi-Fi to
make it visible in the Enphase App. The IQ Gateway also
houses advanced algorithms that control and optimise
your Enphase Energy System for the best performance.
The IQ Gateway uses a Communications Kit as an
accessory to enable communication with IQ Battery 5P.

Enphase Energy System with IQ Battery 5P Owner’s Guide
Know your smart prole
Your Enphase Energy System features a Self-Consumption smart prole, which helps maximising usage of solar and storage
power at your home.
Self-Consumption prole always prioritises your consumption or storage of your produced solar energy. It enables you to
use as much as possible of your generated energy at your own home.
This prole is only available for Enphase Energy Systems that include compatible Enphase IQ Batteries.
11
Enphase Energy System with IQ Battery 5P Owner’s Guide
Normal operation in the Self-Consumption prole
always prioritises the consumption or storage of solar
production over export to the grid. In jurisdictions where
export is not allowed (zero export regulations), energy is
never exported to the grid.
During daylight hours, energy is used to power the home
or charge the batteries.
Operation in Self-Consumption prole
During regular operation, solar production
powers the home and charges the battery.
Once the battery is fully charged, solar
production powers the home, and the excess
solar power generated is exported to the grid.
In cases when the home is consuming more
power than solar production can provide, the
battery starts discharging to meet the power
requirement.
12
Enphase Energy System with IQ Battery 5P Owner’s Guide
Charge battery from the grid
is an additional feature that
you can enable to charge your
battery from the grid when the
energy prices are low.
To enable Charge battery from
the grid through the Enphase
App go to Menu→ Settings→
Battery. As shown below you
can schedule a time window
during which your batteries can
be charged from the grid. Usual
practice is to enable/schedule
Charge battery from the Grid
when the utility rates are low.

System care
14
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.
Shutdown due to communications system failure
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:
Overview of G100 and related shutdown
15
Enphase Energy System with IQ Battery 5P Owner’s Guide
As a recommendation, check with your installer if the allowable export limit on site is appropriate to your system to avoid
future grid export violations.
This is only applicable if your site has a pre-dened power export limit which is set by your installer during the
commissioning of your Enphase Energy System.
If the solar PV system starts exporting power to the grid beyond the authorized export limit, the Enphase solar PV and
battery system is required to fully shutdown and notify the homeowner and installer.
To self-recover the system from a grid export limit violation through the Enphase App, click Restart Now.
1. Grid export limit violation:
16
Enphase Energy System with IQ Battery 5P Owner’s Guide
As recommendations to homeowner in the event of an grid import limit violation:
• Check with your installer if the allowable import limit on site is appropriate to your system to avoid future grid import
violations
• Ensure that you turn-o signicant loads such as an EV charging point or heat pumps before you restart the
Enphase system to avoid any further overload of the cut-out fuse.
• Avoid turning-on high power devices all at the same time, this may result in an import limit violation.
2. Grid import limit violation:
This is only applicable if you have a battery on the site and it is charging from the grid.
In this case when the site starts importing power from the grid to charge the battery beyond the allowed import limit set
by the installer during system commissioning, the Enphase solar PV and battery system is required to fully shutdown and
notify the homeowner and installer.
To self-recover the system from a grid import limit violation through the Enphase, click Restart Now.
17
Enphase Energy System with IQ Battery 5P Owner’s Guide
Self-recovery from grid import/grid export power violation mentioned above can only be done for a total of three times
within a 30-day period by the homeowner.
If a total of four grid import or grid export power violations occur within a 30-day period, your system will get locked
out and will require engagement from Enphase customer support to recover. Reach out to us at https://enphase.com/
en-gb/contact to investigate such behavior on site before allowing system operation to resume.
