NOTE: The main switch on the inverter is to remain ON.

The inverter can be set-up for stand-
by power operation. If AC input is dis-
continued to the motorhome, the inverter
will automatically provide AC power.
When external AC power is resumed, the
inverter will return to “stand-by” mode.
The stand-by mode is activated by
momentarily depressing the “on/off”
inverter remote button while the
motorhome is plugged into shore power
or operating from the generator. Stand-by
mode is indicated by the inverter status
light blinking. Battery charging is not
affected by stand-by operation.
NOTE: Remember to disable this function when not in use.
It may run down the house batteries.

Whether hooked to shore power or operating from the generator, the inter-
nal battery charger of the inverter will automatically charge the batteries when
AC power is supplied to the input terminals of the inverter. The time it takes to
charge the batteries to a full state of charge varies greatly. It can take several
hours or even days, depending on the inverter set-up parameters and actual
state of charge of the batteries. The inverter uses a three stage charging cycle.
The first stage is “bulk” charge. The “bulk” charge will bring the DC voltage
up high, initially between 14.2-14.5 volts, depending on conditions. The bulk
charge cycle is a timed event which the inverter manufacturer has pro-
grammed. The second stage is the “absorb” cycle. The battery voltage in this
cycle is approximately 14.0 volts. The length of the absorb cycle will vary with
state of charge of the batteries. The final stage is the “float” charge cycle.
Approximately 80 percent of the charging has been completed at this time. The
float charge voltage is generally around 13.3-13.7 volts. The last 20 percent of
the charge cycle of the batteries typically takes the most amount of time.
The charging cycle is repeated each time AC power is discontinued and
reconnected. Continuous bulk charging may boil the batteries from a constant
higher than normal DC voltage.
NOTE: The inverter will charge the batteries with AC power
applied regardless of remote status.
