The relay contacts are limited to 50 amps per phase or leg. The continuous loads on that output
should never exceed this number. When connected to an AC source, the Radian inverter cannot limit
the load current. An overload condition is possible.
The inverter does not filter or actively condition the AC source. The voltage and power quality
received by the output loads is the same as that of the source. If the voltage or quality do not meet
the inverter’s input requirements, it will disconnect and return to the inverting mode.
NOTES:
To ensure a smoother transition, it may be advisable to raise the inverter’s lower acceptance limit.
The default setting is 108 Vac on both L1 and L2. A higher setting will cause the inverter to transfer sooner
in the event of a quality problem.
If the AC source meets the inverter’s requirements but is irregular, any fluctuations will be transferred to the
loads. If the loads are sensitive, it may be necessary to improve the quality of the AC source.
The
Generator input mode is intended to accept irregular or unfiltered AC sources and is more likely to do
so than other modes. This should be considered before using this mode with sensitive loads. (See page 14.)
If the charging function is turned off, the inverter will transfer power from the source but will not use it
to charge. If the inverting function is turned off, the inverter will transfer (“pass through”) the source
power when connected, but will not invert when the source is removed.
In a stacked system, slaves are ordered to transfer at the same time as the master. If a slave does not
sense an AC source at the same time as the master, it will continue inverting, and will experience a
Phase Loss warning (see page 56). This appears as an Event on the MATE3 system display.
