energy tab at any point in the charging session, you do not have to unplug or
restart. The session will stop at the set time, or you can stop it earlier
through the app or car. YOU MUST TURN OFF PLUG AND CHARGE FOR THIS FEATURE
11
ENERGY TAB
On the top is the grid, the middle is your home and the bottom you will see
your charger. In the grid section, you will see either one number or three
numbers, depending on whether you have a single or three-phase charger. A
positive number means your home is drawing power from the grid. If you see
that the number is negative, then that means you are producing excess solar,
which is being exported to the grid. The number next to your charger
represents the charging speed.
12
CHARGING MODES
FAST MODE
In this mode, the vehicle will be charged at maximum power. This power can
come from a renewable energy source or the grid. If you have set a current
limit on the schedule or by the electrician during installation that will
determine maximum power.
SOLAR ASSIST
This mode will charge your EV at a minimum of 6 Amps plus any excess solar
produced. If solar production is low, up to 6 amps will be drawn from the
grid.
This is the preferred solar mode, particularly on cloudy days or when you have
a smaller solar system. This will ensure a continuous charge plus any excess
solar that your home generates.
SOLAR ONLY
This mode charges your EV only when enough excess solar is produced. Note that
there is a minimum amount of amps that need to be produced before the solar
mode will start charging. This is because electric vehicles do not like being
charged slower than these levels. The minimum depends on the charger
configuration:
Single Phase – 7 Amps
Three Phase – 20 Amps total across all three (3) phases.
If the solar production drops below the Single or Three phase threshold the
charging will pause and then restart after 2-3 minutes of continuous excess
solar above the Single and Three phase threshold.
We recommend this mode when you have a clear excess of solar power produced.
Use Solar Assist when your production is low or intermittent.

IQ HOME SOLAR
DOES THE CHARGER NEED TO BE CONNECTED TO THE INTERNET? The charger must be
connected to the internet to function normally. · Ethernet using a CAT 6 cable
to your internet modem · WI-FI to the charger
Installer will need to enter the WIFI name and password into the charger
backend. Please note a minimum of 4 bands is required to have a strong and
stable
connection. It is the homeowner’s responsibility to supply a reliable internet
connection where
the charger is to be installed. If either of these is unable to be implemented
then we recommended a TP link
WI-FI extender.
WHAT HAPPENS IF MY CHARGER GOES OFFLINE OR LOSSES INTERNET? If the unit goes
offline the charger will actively try to re-connect. The app will not work if
the WI-FI has dropped out. If this happens charger will not work unless “plug
and charge” was set on the app or until the WI-FI signal returns. If you
change WI-FI password you will need to refer to the installation guide to
reset it.
HOW FAR CAN THE CHARGER BE FROM MY ELECTRICITY SUPPLY? The unit must be
installed within 15 meters of your home’s electricity box which is exporting
electricity. The CT clamps are configured for accuracy and a distance greater
than 20m can affect the accuracy of the readings.
15
SHOULD I PURCHASE A SINGLE PHASE (7KW) OR THREE PHASE (22KW) CHARGER?
The 7kW option available is a single phase (1P) charger whereas the 22kW
option is a three phase (3P) charger. Which phase charger you chose depends on
the phase of your EV, house supply and solar inverter. If you’re not sure what
type of power supply you have in your home, please speak to your electrician.

IS THE OCULAR IQ HOME SOLAR COMPATIBLE WITH ALL EVS? Yes, The IQ Home Solar is compatible with every EV in Australia.
DOES THE OCULAR IQ HOME SOLAR WORK WITH ANY SOLAR SYSTEM?
Yes. If you have a solar system that is constantly exporting electricity to
the grid, then the Ocular IQ Home Solar will allow you to use that excess
solar efficiently to recharge your vehicle’s battery. CT Clamps installed on
the incoming mains supply are used to measure the excess solar being sent to
the grid in real time.

16
DO I NEED SOLAR TO USE THE OCULAR IQ HOME SOLAR? No, the hardware unit can be
operated as a smart EV charger that can still schedule, record and monitor all
your charging sessions. Solar modes or CT clamps can be connected in the
future for an added cost. The CT clamps will also allow the charger to be load
managed, meaning that your home is protected from overloading during charging
sessions.
WHAT HAPPENS IF I HAVE A HOME BATTERY? For the most part, any excess solar
produced by the system will be absorbed by the battery. The Ocular IQ Home
Solar modes work by using CT clamps to understand what you are exporting out
to the grid. You may find that the home battery is absorbing most of your
excess solar generated first and so what’s going out to the grid is minimal.
Despite this, it’s fine to still install a charger, but you may find the Solar
Assist mode best to draw a small amount from the grid/battery when no excess
solar is being produced. If there is excess solar available, it can then
utilise the available excess solar that the battery is not taking. Every
battery system behaves differently, and the ocular team cannot guarantee the
interaction between the charger and the battery.
HOW MANY CT CLAMPS ARE PROVIDED? One CT for single-phase versions and three
for three-phase versions. You must only use the CT clamps provided or an
approved CT from the Ocular team. This is to ensure that the solar and load
control readings are accurate at all times. CTs are supplied in the charger
box.
DOES THE UNIT CONNECT DIRECTLY TO A HOME BATTERY? The unit does not connect
directly to the battery. It uses CTs to monitor the excess solar being
exported to the grid at the home’s switchboard. We do not connect directly to
any battery system.
WHAT MODE SHOULD I CHOOSE BASED ON MY SOLAR PRODUCTION? This depends on the
mode you have set the IQ Home Solar to.
Fast Mode In this mode, the vehicle will be charged at maximum power. This
power can come from solar panels, the grid or both. If you have set a current
limit on the schedule or by the electrician during installation that will
determine maximum power. There is NO minimum amount of excess solar energy
required for use.
17
Solar Assist This mode will charge your EV at a minimum of 6 Amps plus any excess solar produced. If solar production is low, power will be drawn from the grid. This is the preferred solar mode, particularly on cloudy days or when you have a smaller solar system. This will ensure a continuous charge plus any excess solar that your home generates. There is NO minimum amount of excess solar energy required for use.
Solar Only This mode charges your EV only when enough excess solar is produced. The minimum excess solar required for use is shown in this table:

If the solar production drops below the indicated threshold the charging will
pause and then restart after 2-3 minutes of continuous excess solar above the
threshold. We recommend this mode when you have a clear excess of solar power
produced. Use Solar Assist when your production is low or intermittent such as
on a cloudy day.
Our experience shows that large variable loads like air conditioning can
absorb most of the solar generation. Use the Energy tab on the Ocular App to
understand the excess available and choose the Solar Assist mode if excess
generation is consistently below the Single and Three phase threshold.
HOW MUCH EXCESS SOLAR ENERGY IS MY HOME IS PRODUCING?
You can tell this from the Energy tab on the Ocular app. This will differ
slightly depending on whether your system is single or three phase. For
single-phase, only one (1) value will be shown on this screen. Reading this is
important for determining whether Solar Only can be used.
18
Single Phase The negative sign indicates that power is in excess and is being
exported from the solar panels to the grid. When this number is consistently
between 0 and -7 amps there is not sufficient excess solar to use solar only.
Three Phase There will be three numbers presented on the app. You can find the
net power exported/drawn from the grid by adding the numbers together.
Solar Only mode will only work when all three (3) phases are exporting greater
than 20 Amps in total. In this example, the Solar Only mode will work at 8
Amps as this is averaged across all three (3) phases. (5+5+14)/3 = 8 Amps per
phase
Solar Only mode will not work when all three (3) phases are exporting less
than 20 Amps. This means that there is no clear excess when summing all three
(3) phases. When summing up all 3 phases, the solar is only exporting 4 Amps,
which is less than the required 20 Amps before charging. Solar excess is
indicated by a negative (-) value. In this case, choose Solar Assist or Fast
Mode if you would like to charge your car.
19
WHAT IS NET METERING? Net metering is a function specific to 3 Phase
installations and only affects solar only and solar assist modes. The charger
monitors the solar excess on all three phases and will charge if the total
excess across all phases is greater than 21 amps, rather than needing 7 amps
individually across each phase. This means that if one phase has a high load,
for example the rest of the household load, the charger will still operate.
CAN I USE MY OWN INSTALLER? If you wish to use your own installer, they must
be a fully qualified electrician. Ocular cannot be held responsible for any
issues or failures of any products caused by the installation process or from
a result of an incorrect setup and configuration. We highly recommend you
engage one of our trained and authorised installers to ensure the unit is
connected correctly the first time. All installers must be trained and
certified by Ocular prior to installation or the warranty will be void.
WHAT IS LOAD MANAGEMENT? The Ocular IQ Home Solar CT Clamps can perform both
solar and load management. If set up by the electrician, it can indicate the
home’s electricity supply capacity. The Ocular IQ Home Solar will then balance
the charging speed based on the real-time load in the house to prevent the
home’s electricity from overloading.
WHERE DO I DOWNLOAD THE OCULAR APP? The Ocular App is required to use the
charger. Click on the Apple or Google App store to download the Ocular App or
search via your relevant app store.
CAN YOU SCHEDULE A CHARGING SESSION? Yes, you can schedule multiple sessions
per day and also adjust your charging speed. Take advantage of solar daytime
charging or schedule to charge off-peak. You must be plugged in before the
start time for the schedule to work. Otherwise, you need to press start on the
App.
20
DO I HAVE TO BE PLUGGED INTO THE CHARGER BEFORE A SCHEDULED APP CHARGING
SESSION? Yes, you must be plugged in before the start of the App scheduled
session to have the schedule function work. Eg. if you set a schedule from 6
pm to 7 pm you must be plugged in before 6 pm for the scheduling to start. If
you plug in after 6 pm then you need to press the start button on the App to
start a charging session. This will override the schedule for the individual
charging session for the day.
IS THE OCULAR IQ HOME SOLAR OCPP COMPATIBLE? Yes, the Ocular IQ Home Solar is
OCPP compatible. Please note, if an OCPP software platform is enabled on the
charger, the Ocular App and some of the local functions of the unit will not
be available.
WILL THE OCULAR IQ HOME SOLAR WORK WITH OFF-GRID SOLAR SYSTEMS? No. We require
a grid connection to ensure reliable charging. A very minimal amount of
electricity may be taken from the grid for a short period of time if solar
production drops suddenly.
WHAT IS THE REFRESH RATE FOR THE ENERGY TAB? The energy tab will be refreshed
every 30 seconds via the cloud servers which are hosted in Australia.
