Input Modes
The FXR inverter has many modes of operation. See the
FXR Series Inverter/Charger Operator’s
Manual
for additional information on these modes, including reasons and considerations for using
each mode.
The modes determine how the inverter interacts with an AC source. Each mode has functions and
priorities that are intended for a designated application. Each of the inverter’s input selections can
be set to a different operating mode to support different applications.

Generator
: This mode enables the battery charging function to tolerate a wider range of generator
performance and waveform irregularities than other modes. The inverter can use generator power even
when the generator is substandard.

Support
: This mode is intended for systems using utility grid or a generator. In some cases the amount
of current available from the source is limited due to size, wiring, or other reasons. If large loads need to
be run, the FXR inverter augments (supports) the AC source. The inverter uses battery power and
additional sources to ensure that the loads receive the power they demand.

Grid Tied
: This mode is intended for grid-interactive systems that are net metered. Once the battery is
charged and protected loads are serve, the inverter will export power to the utility grid. Grid support
functionality is available in this mode.
NOTE: This mode is only available in 24-volt and 48-volt models.

UPS
: This mode is intended for systems primarily intended to maintain power to the loads with minimal
interruption when switching between AC input and batteries. The response speed has been increased so
that if an AC disconnect occurs the response time will be minimized.

Backup
: This mode is intended for systems that have the utility grid or a generator available, but do not
have specialty requirements such as selling or support. The AC source will flow through the inverter to
power the loads unless power is lost. If power is lost, then the inverter will supply energy to the loads
from the battery bank until the AC source returns.

Mini Grid
: This mode is intended for systems that have the utility grid as an input and a sizable amount
of renewable energy. It behaves like an off-grid system using the utility grid as a backup generator. The
system will use the renewable energy until the battery voltage falls to a specified low level. When this
occurs, the inverter will connect to the utility grid to power the loads. The inverter will disconnect from the
utility grid when the batteries are sufficiently recharged.

GridZero
: This mode is intended for systems that have the utility grid as an input and a sizable amount
of renewable energy. The loads will remain connected to the utility grid, but will restrict the grid use
except 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
(from renewable sources) while remaining grid-connected. This mode does not allow the inverter to
charge batteries or sell. Grid support functionality is available in this mode.
See the
FXR Series Inverter/Charger Operator’s Manual
for additional information on these modes,
including the reasons and considerations for using each mode.
Programming
Selection of the input modes and all other inverter programming is performed using a system
display such as the MATE3s. This product can customize a wide range of parameters.
