13. The Inverter Light on the inverter control panel has a solid green light indicating correct inverter
operation. At this point, apply AC loads up to the inverter's rated capacity to verify full-power
operation.
14. Disconnect all AC loads. The Inverter Light blinks, indicating that the inverter has returned to Load
Demand mode.
15. If the Load Demand function is not appropriate for the intended application, change the Load
Demand Switch, Switch 1, to the OFF position. This will allow the inverter to be fully ON
continuously unless switched off with the On/Off front panel switch or remote control.
9.2 PROCEDURE TO CHECK BATTERY CHARGER OPERATION
Due to the amount of time to perform this procedure, verifying the battery charger function, it may
be postponed to a convenient time.
Determine the correct charger output amps and place the front panel switch (3) position to match
this value.
To test the battery charger operations, first discharge the battery by placing a large AC load
(approx. 50% of the unit‟s rated capacity) on the system and operating the inverter with AC input
disconnected. The AC load will discharge the battery over a time relative to the amount of battery
capacity, size of load, and ambient temperature.
When the battery charge level is low, the Battery Low Light turns on and will stay on until the battery
voltage has dropped to the Battery Low shutdown. The inverter then shuts off and the Light begins
to blink. The battery voltage has decayed to 10.5 Vdc. Now, apply shore power and observe the
battery charger operation. The system begins with the Charger-Bulk Light blinking, indicating bulk
charge operation. This supplies a constant current charge output. Connect an ammeter to the DC
cables between the inverter and the battery to monitor the current (DC amps), and a voltmeter to
the battery to monitor the battery voltage rising.
After some time, the battery voltage rises to the Absorption voltage (14.4 VDC for wet batteries or
14.1 VDC for gel batteries). The Charger-Bulk light continues to flash, indicating the charger is in
Bulk or Absorption mode. The battery voltage remains constant (Absorption voltage value), and the
charger output current tapers off. After approximately twenty minutes, the charge advances to Float
mode. The Charger Float Light turns ON and the battery voltage drops to the float voltage value
(13.2 VDC for wet batteries or 13.6 VDC for gel batteries). The charger will remain in this stage until
shore power is removed or until the battery will again accept the bulk charge amperage.
