2.0 IMPORTANT SAFETY INFORMATION

Solar power systems are safe when operating correctly, however, there are potentially dangerous hazards
associated with some system components.

Please read the following warnings before operating the system.

2.1 Warnings

DC Electrical The storage battery system can contain potentially lethal DC voltages and the casing should not be

opened by anyone other than a registered electrician.

Electrical Wiring This installation has been installed in accordance with AS/NZS wiring standards by a registered

electrician. Any unauthorised altering of the wiring presents the risk of high voltages being exposed,
and the risk of death or serious injury to users of the property where the system is installed.

3.0 ACTIONS IN CASE OF SYSTEM FAILURE

In an emergency, you can shut down the battery system, if it is safe to do so, as outlined in Section 4.0. For other issues,
please refer to Section 7.0 on ‘System Issues’.

4.0 START-UP AND SHUT-DOWN PROCEDURES

Under normal circumstances, the system should not need any intervention. In an emergency, or should your electrician need
to work on wiring in the house, the system may need to be shut-down. The following procedures should be followed.

4.1 System shut-down procedure

1. Turn OFF the AC SOLAR SUPPLY MAIN SWITCH which is labelled and located in the switchboard.

Do not open the battery system enclosure to isolate or disconnect the batteries.

The battery system will still be energised internally by the batteries.

4.2 System start-up procedure

1. Turn ON the AC SOLAR SUPPLY MAIN SWITCH which is labelled and located in the switchboard.

The inverters will take at least 60 seconds to reconnect to the grid following a shut-down or grid outage.

5.0 INTRODUCTION

5.1 How it works

The grid-connected solar power system generates electricity directly from the sun’s energy for use in your home. It is used to
power appliances, lights, the hot water cylinder and anything else that is drawing power at the time. The battery system will
automatically detect when the solar system is generating surplus electricity and begin to charge. If the system is fully
charged, and the supply from the solar system still exceeds your energy demand, electricity will be exported to the grid. This
energy is metered and is purchased by your electricity retailer at an agreed tariff.

When the solar system is not generating enough to supply the load requirements of your home and the batteries are
charged, the battery system supplies electricity to your home. If your energy demand exceeds the battery system’s supply
capacity, or it is fully discharged, additional electricity is drawn from the grid.

You will still purchase power from the grid, on a rainy day for example, when the solar array can’t supply enough energy to
supplement your household loads and the battery is already fully discharged. And vice versa; if the battery is fully charged
and the electricity production of the solar array exceeds the current household demand, clean energy will be exported to the
grid.

6.0 THE STORAGE BATTERY SYSTEM

6.1 Battery enclosure

The battery enclosure houses the batteries and the inverter. The Panasonic storage
battery system is a stand-alone system and comes with an integrated inverter. The
inverter converts the direct current (DC) electricity stored in the batteries into 230V
alternating current (AC) electricity for use in your home.
Beside the inverter the enclosure contains, depending on the model, 2 lithium-Ion battery
cells with a maximum usable capacity of 2.8kWh each.
The battery system usually operates in the ‘maximum self-consumption mode’. This will
ensure that you get the most out of the solar and battery system. It will only charge when
there is surplus solar energy generated on your roof, and will discharge whenever your
home energy demand is higher than what the solar system can deliver. This reduces the
amount of electricity that is exported to the grid and increases the clean energy directly
used in your home.

6.2 Network adapter

The Network Adapter connects the battery system to the monitoring server. This server is managed by solarcity and
operated by Panasonic NZ. The connection to the server enables you and solarcity to monitor the battery performance and
allows early detection of possible faults. It also allows the battery to be run in ‘server adaptive mode’ which is explained in
section 6.4 below.

6.3 Monitoring

The battery system can be monitored through a smartphone application that is available for Android and iOS devices.
You can download the Panasonic monitor application from the Apple app store or the Google Play store.

For iOS the application can be found here:

For Android the application can be found here:

To obtain your login details please contact solarcity.

6.4 Server adaptive mode

In some instances, it can make sense to charge the battery over night at a lower electricity rate. This can be the case
during winter, when your household electricity use increases or your solar generation decreases meaning there is not
enough surplus solar electricity generation to fully charge the battery during the day. If your retailer offers a ‘day­night’ tariff, you might gain some financial benefit from using this function during winter.

If requested by the customer, solarcity has the option to run the battery in ‘server adaptive mode’ which will take
advantage of their specific low overnight prices. In this mode of operation, the battery can receive commands from
the utility server. The server uses a smart algorithm to charge the batteries when your power prices are the cheapest
and discharge the batteries when your power is most expensive.

This will not affect the battery’s ability to store surplus solar energy. The system will work to maximise self­consumption and only charge overnight if required, and if it makes financial sense to do so.
