3. Clean the selected area thoroughly to remove any oil or grease that could
prevent the sensor from adhering to the battery case. Allow the battery case to
dry thoroughly.
4. Peel the backing from the self-adhesive strip on the rear of the sensor. Press
the sensor firmly against the clean side of the battery to fix it in place, as
shown in Figure 2-7.
5. Route the sensor cable to the inverter/charger and plug it into the Battery
Temp. jack. Secure the cable along its length.
The RV Series Inverter/Charger is equipped with a sophisticated automatic
generator start (AGS) feature that can be accessed through the RC/GS Remote
Control. The RV Series Inverter/Charger AGS uses three dry contact relays to
operate the auto-start function of your AC generator. Proper installation and setup
of the generator is essential for correct operation of the inverter/charger. The RC/
GS contains the software code to work with various generators listed on its Select
Genset menu.
The RV Series Inverter/Charger AGS can be configured to start Onan
QuietDiesel, PowerTech and Generac-brand generators. For more information
about selecting a generator configuration, see the RV Series Remote Control
Owner's Manual.
The maximum charge rate of the battery charger is dependent upon the peak AC
voltage available. Because this type of battery charger uses only the peak part of
the input sine wave, small variations in peak voltage result in large variations in
the amount of energy available to the charger. The charger's rated output is based
on a utility voltage of 120 Vac
164 Vac .
p
It takes a powerful AC generator set to maintain the full 164-volt peak while
delivering the current necessary to operate the charger at its maximum rate. As a
guideline, the rated output of the generator should be double the inverter output
(for example, a 5,000 W generator for a 2500 W inverter/charger). Smaller
generators will have the tops of their waveform clipped under such charger loads.
Running at these reduced peak voltages will not harm the charger, but it will limit
the maximum charge rate. Large auxiliary AC loads may make this problem
worse.
