3.0 Setup
transfer time from Charge mode to Inverter mode is >16 milliseconds
when using these settings.
Dropout = UPS Mode
-
Use the
UPS Mode
setting when the AC source
is well regulated above 105 VAC (210 VAC for export inverter models)
and the inverter loads are sensitive to voltage
fl
uctuations. This setting
is intolerant of voltage
fl
uctuations and will provide a quick transfer. The
transfer time from Charge mode to Inverter mode is
≤
16 milliseconds
when using this setting. Do not use this setting if using a generator as
your AC source.
Info:
If you get nuisance AC disconnects, either change the
setting to 100 VAC or less (export inverter models: 200 VAC or
less), or obtain a better voltage regulated AC source.
03E Absorb Done (Time, Amps, SOC):
This setting determines whether
time, amps, or SOC are used to determine when the second stage of
battery charging, or Absorption Stage, is
fi
nished and transitions to
the
fi
nal charge stage (see
03G Final Charge Stage
). Absorption is the
second stage of the charge process and the batteries will be almost fully
charged.
Info:
If the Absorb stage is short or terminated, the batteries
may not receive a full charge. In contrast, if the Absorb stage
is too long the batteries may be overcharged. Either scenario
may lead to damage to the batteries. Contact your battery
manufacturer to ensure the best charge settings are used for
your type of batteries.
Set Absorb Done Time
-
Set Absorb Done Time
is used when a speci
fi
c time
is determined to be the best solution for ending absorption time. When using
time, the battery bank size will typically determine the length of the absorb
time setting. Taking speci
fi
c gravity readings of the batteries and adjusting
the absorb time may be needed in order to obtain the appropriate absorb time
for your battery type and battery bank size. The larger the battery bank the
longer the absorb time to ensure the batteries receive a full charge, or you
can use Table 3-2 to select the setting – as a general rule of thumb.
