Section 1: Introduction
About Pika Islanding Inverters: X7602/X11402
Islanding Inverters connect to the Pika PV Link optimizers to form the Pika Energy Island system
for grid-tie solar-plus-storage. Upon the loss of grid power, Islanding Inverters disconnect from
the grid and provide AC power to support protected loads. The inverter provides islanding power
without an external autotransformer. High voltage smart-batteries connect to Islanding Inverters
with no additional storage interface.
All Pika Energy products use the REbus™ 380VDC nanogrid to connect energy sources, storage,
loads, and the grid. The REbus nanogrid automates the ow of power to enable plug-and-play
setup and operation of Pika Energy equipment. For more information about REbus, visit pika-
energy.com.
In the diagram below, an X7601 is directly connected to PV Link optimizers and high voltage
lithium ion storage on the DC (REbus) line, shown the the left of the inverter. To the right of the
inverter are AC lines: 240VAC for grid and home loads, and protected load support up to 50A.

Section 3: Operational Modes Overview
Note: Some operational modes require current transformers to be installed with the
Pika Energy Island. See “Connecting Current Transformers (CTs)” on page 22 of
the Islanding Inverter Installation Manual for more information.
The Pika Energy Island has several operational modes available for various installation
congurations, markets, and applications. Connected REbus devices work together to manage
the distribution of power based on the selected operational mode.
Some modes interact with high voltage smart batteries over REbus to store power and/or balance
production and consumption.
Use the following charts to select the correct operational mode for X7602/X11402 to meet your

Section 3: Operational Modes Overview
Grid Tie
In Grid Tie mode, X7602/X11402 functions as a conventional grid-tied inverter system. The
system powers local loads, and when generation exceeds load demand, excess power is
exported to the utility for net metering and other credits. Current transformers are optional for
this mode. Without current transformers, the inverter LCD will not display separate house and grid
consumption.
In the event of a grid outage, the battery will power the system until it is depleted. For applications
in which batteries will be connected to the Pika Energy Island at a later date, operate in Grid
Connect mode until batteries are installed.
Clean Backup
In Clean Backup mode, Islanding Inverters prioritize keeping batteries charged and ready for grid
interruption, using only solar power. Current transformers are optional for this mode.
If the battery is not fully charged, X7602/X11402 will use all available solar power to charge the
battery. Grid power will not be used to charge batteries in this mode.
Fig. 3.1 Fig. 3.2 Fig. 3.3
When the batteries are full, solar power is exported to the AC terminals of the inverter, providing
power to the building along with the grid [Fig. 3.1].
When the battery is fully charged, any solar power not used in the building is exported to the grid
[Fig. 3.2]. When grid service is interrupted, the system will immediately enter Islanding Mode,
powering protected loads with solar and battery power together [Fig. 3.3]. If there is enough solar
power available, the solar will simultaneously charge the battery and support the loads.
10 Islanding Inverter Operation Manual M00010-17
Priority Backup
Priority Backup
In Priority Backup mode, Islanding Inverters prioritize keeping batteries charged and ready for grid
interruption, using solar power or grid power. Batteries charge using solar power as it is available,
and take additional power from the grid to charge as fast as possible. Current transformers are
optional for this mode.
If the battery is not fully charged, all available solar power will be used to charge the battery, with
the goal of lling the battery before a grid failure. If available solar power does not meet bus
voltage requirements for recharging the battery, the grid will provide power to expedite battery
recharging.
Fig. 4.1 Fig. 4.2 Fig. 4.3
If solar and grid power are available, both can be used to charge the battery. With current
transformers installed, the system will display the amount of power being drawn from the grid
and how much is being consumed by local loads before reaching the battery [Fig. 4.1]. Without
current transformers, only DC power being used to charge batteries through the inverter [Fig. 4.2]
will be displayed.
In the event of a grid failure, the inverter will enter Islanding Mode. Protected loads are supported
by solar and battery power. If there is enough solar power available, the solar will simultaneously
charge the battery and support the loads [Fig. 4.3].
Self Supply
In Self Supply mode, X7602/X11402 prioritizes powering local loads using solar and/or stored
power rst. Current transformers are required for this mode.
In this mode, generated solar power will be used to charge batteries before any power is exported
to the grid. This mode is optimal in markets in which net metering is unavailable or unfavorable,
making battery-stored power economically more attractive than grid-provided power.
11 Islanding Inverter Operation Manual M00010-17
Section 3: Operational Modes Overview
Fig. 2.1 Fig. 2.2 Fig. 2.3
If more power is being produced by the solar array than is needed by local loads, X7602/X11402
will store energy in the battery for later use [Fig. 2.1]. If the battery is full and a surplus of power
is available, that surplus is exported to the grid [Fig. 2.2]. When local demand exceeds available
solar-generated power (e.g. at night), the battery supplies power to support local loads. [Fig.
2.3] If the building requires more power than the battery and solar can provide, then the excess
demand is supported by the grid.
Self Supply Setpoints
In certain situations, it is possible to use the TargMinImprtP and TargMaxImprtP setpoints to
allow the building to deliberately import power from the grid within certain limits. This is useful
for specialized applications, including peak avoidance.
These setpoints are only relevant to Self Supply, and are typically only useful for specifc
applications. Please contact Pika Energy for more information on how to use these setpoints for
your application.
Setpoint Description Default Units
TargMaxImprtP Target Maximum Import Power
Maximum level of power you would like to import from
the grid at any point. If the overall building load is greater
than this setpoint, then the inverter will supply additional
power from the battery and solar array to keep the grid
import power below this level.
This maximum is not guaranteed. If there is not enough
power available from the battery and solar to cover the
load, then the grid will supply the additional power.
0 W
12 Islanding Inverter Operation Manual M00010-17
Sell
Setpoint Description Default Units
TargMinImprtP Target Minimum Import Power
Use this setpoint to charge the battery from the grid
while in Self Supply. If the overall building load is less
than this setpoint, the inverter will import power to the
battery to keep the grid import power up to the setpoint.
If the building load is above the setpoint, the inverter will
not import additional power to charge the battery.
This minimum is not guaranteed. Once the battery is full,
grid import power may fall below this level.
0 W
Sell
This mode commands the system to export all available power to the grid. Any connected
batteries will drain to the grid until their state of charge reaches the “Min Arbitrage” setpoint (refer
to your battery documentation for explanation of battery setpoints). Once a battery is depleted to
this point, it will not charge again until the operational mode is changed.
Zero Export
In some markets, solar PV systems are prohibited from back-feeding the AC grid. For these
applications, enable Zero Export. With Zero Export enabled, the inverter will not send excess
solar power to the grid. Instead, the system will limit solar power generation such that it exactly
matches the power consumed by local loads resulting in no exported power. Current transformers
are required for this mode.

Enabling and Disabling Devices
The Pika Energy Island system is able to operate independently without input from a user. The
inverter and other parts of the system are able to return to operation automatically, even after
events such as power outages. To ensure this behavior is safe and predictable, all REbus devices
must be Enabled by the user before they will operate. Enabling the device gives it permission to
resume operation on power-up. If a device is Disabled, it will stay in a Disabled state, and will not
resume operation until it receives user input.
Once Enabled, if grid power is present the X7602/X11402 will create a DC voltage, establishing
the REbus nanogrid. Devices connected to REbus will wake up and begin communications.
Each connected device must be Enabled before allowing it to operate. Once Enabled, connected
devices will automatically resume operation whenever a REbus DC nanogrid is established.
If a device has never been enabled, it will stay in a “Disabled” state until it is enabled by a user.

Periodically check the intake lter on the bottom of the enclosure to ensure it is not clogged with
dust. Clean the lter with a soft brush or vacuum cleaner. Clean the exterior of the enclosure with
a soft cloth.
Recovery From an Error State
Error events will force X7602/X11402 into a error state where no DC power is exported, though
voltage may still be present on REbus from connected devices. To recover a device from an error
state, use the front control panel to Disable and then Enable the device. If the system is unable to
be accessed, but is connected to the internet, call Pika Technical support at (207) 808-0362 for
assistance in resetting an error state.
