5.0 Operation

5.2 Operating the Inverter/Charger

5.2.1 Inverter Mode

Turning the inverter on:

Press the ON/OFF INVERTER button to activate the

inverter function. The inverter will either be actively “Inverting” by using power

from the batteries to power the AC loads (see Figure 5-4); or, the inverter will

be “Searching” for a load by using very little power from the batteries, if in

Search mode (see Figure 5-3). The green INV LED is on when the inverter is

actively inverting, and the green INV LED

ashes while searching.

Turning the inverter off:

While the inverter is actively inverting or searching,

press the ON/OFF INVERTER button to switch the inverter function off; which

turns the green INV LED off (see Figure 5-2).

Inverter Standby:

The inverter is in standby when it is active (green INV

LED is on) but not actively providing power from the batteries to the inverter

loads. This can happen when an external AC power (utility/shore or generator)

is passing through to power the AC loads; or, in a parallel application where

the slave inverters are not actively powering a load, but ready and waiting

to power the load if needed.

5.2.2 Charger Mode

Turning the charger on:

The Charge mode is automatically activated and

begins when acceptable AC power (utility or generator) is connected to the

input of the inverter. While in Charge mode, the display shows

Absorb Charging

Float Charging

Charger Standby

Silent

Force Float

, and

Equalizing

(see Figures 5-6 thru 5-14). (When the

charger is ON and actively charging, it produces DC voltage and current to

charge your batteries, and the CHG LED is solid.)

Charger Standby:

When the charger is actively charging, press the ON/OFF

CHARGER button to switch the charger to Charger Standby. While in Charger

Standby, the incoming AC is still available on the inverter’s output, but the

charger is not allowed to charge. The LCD displays

“Charger Standby”

and

the CHG LED

ashes (see Figure 5-11).

Info:

To resume charging momentarily press the ON/OFF

CHARGER button, or disconnect/reconnect AC power to the

inverter’s input.

Equalize charging:

Equalizing is a ‘controlled overcharge’ performed after

the batteries have been fully charged. It helps to mix the battery electrolyte

(to reverse the buildup of strati

cation), and also helps to remove sulfates

that may have built up on the plates. These conditions if left unchecked will

reduce the overall capacity of the battery.

WARNING:

Do not perform an Equalization charge without

reading and following all safety precautions pertaining to

charging/equalization as noted in this manual, and any

equalization information in the inverter’s manual.

To enable the Equalization charge, see Figure 5-14 and follow all related

information on page 60.
