Inverter to Charger Transition

The RV Series Inverter/Charger produces up to 3000 watts (depending on model)
of continuous, modified sine wave power from a 12-volt battery bank. It is ideal
for simultaneous applications including microwaves, TV entertainment systems,
fax machines, computers, and power tools.
The RV Series Inverter/Charger provides automatic, multistage battery charging,
manual battery equalization and temperature sensitive charging with an optional
battery temperature sensor. The charger is designed for use with electricity
supplied from your generator or RV campground hookup.
The RV Series Inverter/Charger also has automatic generator start (AGS)
capability. When the inverter/charger is connected to an Onan QuietDiesel,
Generac or Powertech generator, it will start the generator to charge the batteries
when battery power is low, or in response to a signal from a thermostat. An RC/
GS remote control is required to configure and use the AGS feature.
Three RV Series Inverter/Charger models are available. Each model has a
different maximum continuous output power rating and surge power rating—the
power necessary to operate motor-driven appliances, which require high current at
startup (see "Inductive Loads" on page 3–4).

The RV Series Inverter/Charger includes a built-in transfer switch that
automatically transfers between inverter power and incoming AC power. To
operate the RV Series Inverter/Charger as a charger, an external source of AC
power (such as shore power or a generator) must be supplied to the inverter AC
input. The inverter/charger automatically stops inverting and begins charging
batteries whenever AC power is connected to its AC inputs. When AC power is
connected, the RV Series Inverter/Charger will begin charging even when the
inverter itself is turned off (with the on/off switch).
There is a minimum 5-second delay from the time the inverter senses that AC is
present at the input terminals to when the transfer is made. This delay is built in to
provide time for a generator to spin-up to a stable voltage and avoid relay
chattering. The inverter will not transfer to generator until it has locked onto the
generator's output. The inverter's AC input is internally connected to the
inverter's AC output while in the battery charger mode.
