Applications
The Radian Series Inverter/Charger is intended for both off-grid and grid-interactive (Grid/Hybrid)
applications. It is designed to use a battery bank to store energy. It can work in conjunction with
photovoltaic (PV) modules to harvest solar energy, as well as wind turbines and other renewable
sources. These sources charge the battery, which in turn is used by the inverter.
The Radian inverter has two sets of AC input terminals. Two AC sources, such as a gas or diesel
generator and the utility grid, can be connected to the inverter. Other combinations of AC sources
are possible.
NOTE:
although this can be changed.
The Radian inverter’s settings can be changed to accommodate many applications.
The inverter can only accept one source at a time. The input marked

Input Modes
The Radian inverter has seven modes of operation. These modes determine how the Radian interacts
with an AC source. Each mode has functions and priorities that are intended for a designated
application. Each of the Radian’s two AC inputs can be set to a different operating mode, so that
different applications can be supported.
Generator
imperfect AC waveform. The Radian can charge from the generator even when the generator is undersized
or substandard.

battery power to the AC source to ensure that the loads receive the power they require.

the loads do not use all the excess energy, then the Radian will return (sell) that energy to the utility grid.

to power the loads unless power is lost. If power is lost, then the Radian inverter will supply energy to the
loads from the battery bank until the AC source returns.
Mini Grid
renewable energy. The system will run off the renewable energy until the battery voltage falls to a specified
low level. When this occurs, the Radian inverter will connect to the utility grid to power the loads. The
Radian inverter will disconnect from the utility grid when the batteries are sufficiently recharged.
Grid Zero:
renewable energy. The system will remain connected to the utility grid, but will only draw power from it
when no other power is available. The default power sources are the batteries and renewable energy, which
attempt to “zero” the use of the AC source. The batteries are discharged and recharged while remaining
grid-connected.

See the Radian Series Inverter/Charger Operator’s Manual for additional information on these modes,
including the reasons and considerations for using each mode.
Renewable Energy
The Radian Series Inverter/Charger cannot connect directly to photovoltaic arrays, wind turbines,
or other renewable sources. As a required part of a Grid/Hybrid system, the batteries are the inverter’s
primary source of power. However, if the renewable sources are used to charge the batteries, the
inverter can use their energy by drawing it from the batteries.
The renewable source is always treated as a battery charger, even if all of its power is used
immediately. The renewable source must have a charge controller or some way to prevent
overcharging. OutBack Power’s FLEXmax family of charge controllers can be used for this purpose, as
can other products.
The GSLC will receive the mechanical and electrical connections for up to two FLEXmax charge
controllers. It can receive the electrical connections for two FLEXmax Extreme charge controllers.

requires nominal 48 Vdc to operate.
H. Battery voltage: Most individual battery
voltages are less than the system DC voltage.
The batteries need to be placed in series to
deliver the correct voltage.
I. Capacity: Battery capacity, which is measured
in amp-hours, is not usually a fixed number.
It is specified based on the rate of discharge.
For example, the OutBack EnergyCell 200RE is
rated at 154.7 Ahr when discharged at the
5-hour rate (to terminal voltage 1.85 Vpc). This is a high rate of discharge that would hypothetically
drain the battery in 5 hours. The same battery is rated at 215.8 Ahr when used at the 100-hour rate.
Use the appropriate discharge rate (correlated to the expected loads) to measure the capacity of a
battery. Use battery specifications for terminal voltage 1.85 Vpc whenever possible.
J. Maximum depth of discharge (DoD): Most batteries cannot be discharged below a certain level
without damage. The bank requires enough total capacity to keep this from happening.
To Calculate Minimum Battery Bank Size (refer to Table 2 for letter designations):
1. The load size, item A, is measured in watts. Compensate this figure for efficiency loss. Multiply the
conductor efficiency by the inverter efficiency (E x F). (These items are represented as percentages,
but may be displayed as decimals for calculation.) Divide item A by the result.
2. Convert the compensated load into amperes (Adc). Divide the step 1 result by the system voltage
(item G).
3. Determine the daily load consumption in ampere-hours (amp-hours, or Ahr). Multiply the step 2
result by the daily usage hours (item B).
4. Adjust the total for required days of autonomy (the days the system must operate without
recharging) and the maximum DoD. Multiply the step 3 result by C and divide by J.
The result is the total amp-hour capacity required for the battery bank.
5. Determine the number of parallel battery strings required. Divide the Ahr figure from step 4 by the
individual battery capacity (I). Round the result to the next highest whole number.
6. Determine the total number of batteries required. Divide the system voltage by the battery voltage
(G ÷ H). Multiply the result by the step 5 result.
The result is the total required quantity of the chosen battery model.

Generator
These Radian models can work with any “split-phase” generator that delivers reliable AC power at the
appropriate voltage and frequency. They cannot work with a single-phase or three-phase generator.
Use of a three-phase generator with this equipment may damage either the inverter or
the generator. This damage to the inverter is not covered by the product warranty.
The Radian inverter/charger can provide a start signal to control an automatic start generator. If automatic
generator starting is required, the generator must be an electric-start model with automatic choke. It
should have two-wire start capability. For other configurations, additional equipment may be required.
In any configuration, the inverter may need to be programmed using the system display.
Perform all programming according to the specifications of the generator and the required operation of the
inverter. Parameters to be programmed may include generator size, automatic starting requirements, and
potential fluctuations in generator AC voltage.
Generator Sizing
A generator should be sized to provide enough power for all the loads and the battery charger.
Available generator power may be limited by ratings for circuit breakers and/or generator connectors.
The maximum allowed AC circuit breaker size is 50 Aac per Radian inverter/charger.
The generator must be able to provide current to all inverters. Minimum generator wattage
recommended to be twice the wattage of the inverter system. Many generators may not be able to
maintain AC voltage or frequency for long periods of time if they are loaded more than 80% of
rated capacity.
A generator that is to be installed in a building usually should not have a bond between the neutral and
ground connections. The generator should only be bonded if there is a specific need. Installations in North
America are expected to bond the neutral and ground at the main electrical panel. See page 22 for more
information on neutral-ground bonding.

Inverter systems are often equipped with AC maintenance bypass switches or interlocks. If the

the inverter. This can minimize disruption to the system and avoids the need for extensive rewiring.

The GS Load Center (GSLC) can be equipped with bypass circuit breakers for this purpose. However, if
multiple Radian inverters are stacked in a single system, then the GSLC bypass kits should not be used.
The bypass function must be simultaneous for all inverters. The GSLC bypass kits operate
independently, not simultaneously.
Both manual and automatic double-throw bypass switches are commonly available in a range of sizes
and options. These are highly recommended for systems with more than a single inverter.
Using independent bypass devices on multiple inverters can result in power being routed to

Location and Environmental Requirements
Radian Series Inverter/Chargers must be located in a weather-proof enclosure or enclosed area. It is
not designed for exposure to water or excessive wind-blown dust and debris. It carries an Ingress
Protection (IP) rating of 20 and a Relative Humidity (RH) rating of 93%.
The Radian inverter must be wall-mounted in an upright position. The inverter is not approved for
mounting in any other position or orientation.
Recommended minimum clearance is 2 to 4 inches (5 to 10 cm) for the front and top of the inverter.
The sides and bottom may be enclosed or obscured with no restriction when mounting accessory devices or
one other Radian inverter. If more than two Radian inverters are installed side by side with the GSLC, the
inverters should be separated by at least 0.9 inches (2.3 cm) to accommodate the GSLC hinged doors.
The Radian inverter will function best if operated in a temperature range of -4°F to 77°F (–20°C to 25°C). At
temperatures up to 122°F (50°C), all inverter components meet their specifications, but the inverter’s power
is derated. It can function in environments as cold as –40°F (–40°C) and as warm as 140°F (60°C), but it may
not meet all component specifications. This temperature range also applies to storage.
The specifications are listed in the Radian Series Inverter/Charger Operator’s Manual.

Mounting
Two or more people may be needed to install the Radian inverter/charger due to its weight.
Mount and secure each component before attaching any wiring. Local or national wiring codes may require
the bottom of the inverter to be enclosed. The GS Load Center was specifically designed for this purpose.
Avoid large air gaps behind the Radian inverter/charger and its mounting plate. These can result in louder
