Introduction
Welcome to OutBack Power
Thank you for purchasing the Mojave™ OGHESS8015A Energy Storage System, or Mojave ESS.
The ESS consists of the Mojave OGHI8048A inverter and the Mojave ESS lithium-ion battery.
This system can be used to add energy storage and backup capability to a grid-direct (GD) inverter
and PV system. It is designed to be “AC Coupled”; that is, the ESS is meant to be installed in
existing grid-direct systems to add energy storage and backup capability without interfering with
grid interaction.
The system has an integrated wireless (wi-fi) hotspot and can also be connected to other local
networks, wirelessly or by using a physical Ethernet connection.
CAUTION: Hazard to Equipment
The Mojave ESS battery may only be used with the Mojave OGHI8048A inverter. The
Mojave ESS battery is not designed for use with any other products.

XCT Power — The net exported power in watts (W) measured at the external current transducers.
This will read zero if the transducers are disabled. See pages 27 and 39.
XCT Current L1 and XCT Current L2 — The current in AC amperes (Aac) measured at the L1 and L2
current transducers. This will read zero if the transducers are disabled. See pages 27 and 39.
Time of Use Status — Disabled, Off-Peak (Grid), On-Peak (Battery). See page 36.
Timer — The timer that runs when the Status is Connecting.
Info — This item lists a series of messages providing additional information to what is shown in Status.
A common message is Grid dropped. It is equally common for this item to read None. When Error is
present as a Status, the specific name of the error will appear here.
See the EVENTS view on page 24 and Troubleshooting on page 63 for more information on symptoms
and errors.

NOTE: The external current transducer (XCT)
fields described in the bullets below will only
appear if the XCT is enabled. (See page 39.)
The current transducers are placed at the main
electrical panel. (See Figure 15 on page 27.)
This point is represented by Ain this image.
When power flows through Afrom left to right
(to the grid), the XCT readings noted below
will be positive values.
When power at A flows from right to left (from
the grid), the XCT readings will be negative,
as shown in the examples on this page.

User Interface
Generator Tab
Figure 8 User Interface (Generator tab, STATUS view)
This tab shows information on the inverter’s connection to an AC generator. This includes the
status of automatic generator starting (AGS), if used. The first item is generator Status:
Warming Up — generator is running without connecting to the inverter. The generator relay is open.
The Timer is counting down the warmup time before connection.
Connected — generator power is accepted for use. The generator relay is closed. The Timer is
counting the generator’s running time.
Disconnected — voltage is present at the GEN terminals, but the power is unacceptable or was
manually disconnected. The generator relay is open.
Cooling Down — generator is running without connecting to the inverter. The generator relay is
open. The Timer is counting down the cooldown time before stopping the generator.
Dropped — generator power was manually disconnected in the Actions Menu. The generator relay
is open.
Error — the inverter has detected a critical problem at the GEN terminals. The generator relay is open.
Not Available — no voltage (or minimal voltage) is detected at the GEN terminals. The generator
relay is open.
NOTE: When a generator is
installed, the generator and grid
icons will switch places.

Additional items under the Generator tab:
Power — The power in watts (W) being imported from the generator.
Frequency — The frequency in hertz (Hz) measured at the inverter’s L1 and L2 G
EN
terminals.
Voltage L1 and Voltage L2 — The voltage in AC volts (Vac) measured at the inverter’s L1 and L2
G
EN
terminals.
Current L1 and Current L2 — The current in AC amperes (Aac) measured at the inverter’s L1 and L2
G
EN
terminals.
AGS Status
Enabled — The AGS function has been activated in the Actions Menu and also in AGS under the
Generator tab. (See pages 22 and 46.) It is waiting for proper conditions to start the generator.
Disabled — The AGS function has been been deactivated in the Actions Menu, in the Generator
tab, or both. The generator may be started manually, but it will not start automatically.
Timer — The timer that runs when the Status is Warming Up, Connected, or Cooling Down.
Info — This item lists a series of messages providing additional information to system operation. AGS
conditions will appear here. A common message is Gen going through warmup period. If the
generator is not in use, this item will read None. When Error is present as a Status, the specific name of
the error (such as At Minimum SOC setting) will appear here.
