As a generator may have wider frequency
fluctuations, these fluctuations will be passed
on to the load. Hence, when a generator is
used as a source of transferred / bypassed AC
power, the load will be forced to operate under
wider frequency fluctuations that will not be
controlled and the user should ensure that when
"Generator Mode" is selected, the loads should
be able to tolerate the frequency variations of
the generator.
!
ATTENTION!
Le générateur pourrait avoir des fluctuations
de hautes fréquences, et ces fluctuations serait
passées à la charge. Ainsi, quand le générateur
est utilisé comme source de puissance
CA transferée, la charge serait obligée de
fonctionner avec des fluctuations de fréquence
qui seront pas controlées. Alors l'utilisateur doit
assurer que la mode «Generator mode» est
sélectionnée, et que les charges sont capables de
tolèrer des variations de fréquences provenant
du générateur.

In off-grid and Rv applications, a generator may be used to charge
the batteries.
Generator Mode should be enabled when the AC input source is a
generator. The voltage output of a generator is likely to have wider
frequency fluctuations due to load variations as compared to very low
frequency variations in the utility / grid AC power.
The default setting is Generator Disable (this mode is displayed and
described as the "Utility Mode"). As the frequency of the utility AC
power does not vary widely, the G4 Series has a narrower window of
+ 5 Hz and – 3 Hz to allow transfer / bypass of the utility power to
the load and carry out battery charging. If a generator is used as the
AC input power source and the G4 is set in "Utility Mode" and if the
frequency variation of the generator is more than + 5 Hz / - 3 Hz, the
G4 will not transfer / bypass the generator output to the load / charge
the batteries.
When the "Generator Mode" is selected, the frequency and phase of the
AC output of the inverter are synchronized with the output frequency
and phase of the generator but the value of the frequency is not
considered for transfer purposes. The inverter remains synchronized
with the generator frequency at all times and the load also sees the
actual frequency of the generator at all times. note: Charging will be
interrupted during the period when generator frequency is not
within the range of 45 - 65 Hz due to overload distortion. Please
see page 14 for more details.
If grid / utility power is being used, please select "Generator Mode –
Disable" to enable synchronized transfer with a maximum permissible
frequency deviation range of +5 / - 3 Hz. Please read details of operation
in Generator Mode on pages 50 & 52 and in Utility Mode on pages 48
& 49.
