Introduction
Welcome to OutBack Power
Thank you for purchasing the Mojave™ Grid-Hybrid Inverter/Charger. This product offers a power
conversion system between batteries and AC power. This inverter can provide backup power
during loss of utility grid, unlike grid-direct (GD) inverters that only convert solar (PV) power to send
to the grid. The inverter contains an onboard wireless (wi-fi) network. It can also be connected to
other local networks, wirelessly or by using a physical Ethernet connection.
The Mojave inverter is designed to be “AC Coupled”; that is, the inverter is meant to be installed
in existing grid-direct systems to add energy storage and backup capability without interfering with
grid interaction.

Battery Bank
IMPORTANT:
Battery charger settings need to be correct for a given battery type. Always follow battery
manufacturer recommendations. Making incorrect settings, or leaving them at factory
default settings, may cause the batteries to be undercharged or overcharged.
CAUTION: Hazard to Equipment
Batteries can emit vapors which are flammable and which are corrosive over long periods
of time. Installing the inverter in the battery compartment may cause corrosion which is
not covered by the product warranty. (Sealed batteries may be an exception.)
NOTE:
If the Mojave ESS battery is in use, refer to the Mojave Energy Storage System
Operator’s Manual in place of the present manual. This manual, also called the ESS
Manual, contains necessary battery and inverter instructions. The ESS Manual also
includes inverter presets for the Mojave ESS battery.
When planning a battery bank, consider the following:
Cables: See the Quick Start Guide for cable sizes, torque values, and other requirements.
The maximum length will determine placement of the battery bank, but should not exceed 10 feet
(3 meters). Local codes or regulations may apply and may take priority over OutBack Power
recommendations.
Battery Type:
These inverters are designed to work with a battery bank of nominal 48 Vdc. The default settings
for three-stage battery charging assume a deep-cycle stationary lead-acid battery, such as OutBack
Power’s EnergyCell™ PLR or NorthStar Blue+ series batteries. The charger settings for many of
these batteries are pre-loaded. (See page 49.) The inverter’s settings can be adjusted for other
battery types.
OutBack Power does not support installation of lithium-ion batteries that have not been tested and
published as installable with OutBack Power equipment.

Power — The net power in watts (W) being imported from, or delivered to (in charging), the battery.
Voltage — The voltage in DC volts (Vdc) measured at the inverter’s internal battery terminals.
Current — The net current in DC amperes (Adc) measured as imported or exported from the batteries.
Temperature — The battery temperature in degrees Celsius as measured by the remote temperature
sensor (RTS) or the BMS.
Temp Offset — Temperature-compensated voltage added to the configured voltage target.
Voltage Target — The configured value for the present charging stage. See page 54.
Timer — The timer that runs when the Status is Float, Absorption, or EQ.
Info — This item lists a series of messages providing additional information to what is shown in Status.
A common message is Discharging to support TOU schedule (when the Time of Use function is
operating). It is equally common for this item to read None. When Error is present as a Status, the
specific name of the error (such as At Minimum SOC setting) will appear here.
See the EVENTS view on page 27 and Troubleshooting on page 79 for more information on
