Generator Control

The

terminals can provide a signal to control an automatic-start generator. The control

function can be

Advanced Generator Start

(AGS), which is situated in the system display. AGS

can start the generator using settings from the system display, or it can use battery readings from

the FLEXnet DC battery monitor. Note that AGS cannot be used if the system display is removed.

Alternately, the control function can be

Gen Alert

, which is a simpler function based directly in the

FXR inverter. The choice of function depends on system needs and the capabilities of each device.

The generator must be an electric-start model with automatic choke. It is recommended to have

“two-wire” start capability. A two-wire-start generator is the simplest type, where the cranking and

starting routine is automated. It usually has a single switch with two positions that is turned

start,

to stop.

Two-Wire Start

The 12 Vdc signal provided by the

output can be switched on and off to provide a start

signal. It is possible to send a 12-Vdc signal directly to the generator. However, this should never

be done if it connects the

output directly to the generator’s own battery. It is more common to

use the

terminals to energize the coil of a 12 Vdc automotive or similar relay.

The OutBack FLEXware Relay Assembly depicted in Figure 19 is sold for this purpose. The relay

contacts can serve in place of the generator’s start switch. The battery shown below ( ) is

depicted for clarity. In most cases the battery is part of the generator’s internal starting circuit and is

not an external component.

The drawing below is one example of a possible arrangement. Specific arrangements, relays, and

other elements depend on the requirements of the installation and of the generator.
