Select Battery Charger-Limiting Points—OPTIONAL
“Most Limiting”
(#B2 & #B1 Up):
Charger-limiting takes effect the moment
any 120V AC load is applied; charger out-
put falls gradually from full output at no
120V load passing through to no output at
full load.
“Less Limiting”
(#B2 Up & #B1 Down):
Charger-limiting begins when the
Inverter/Charger’s load reaches 33% of the
Inverter/Charger’s load rating. Charger
output falls gradually from full output at
33% of the Inverter/Charger’s load rating to about 40% of full output
at full load.
“Least Limiting”
(#B2 Down & #B1 Up):
Charger-limiting begins when the
Inverter/Charger’s load reaches 66% of the
Inverter/Charger’s load rating. Charger
output falls gradually from full output at
66% of the Inverter/Charger’s load rating to about 40% of full out-
put at full load.
“No Limiting”
(#B2 & #B1 Down): No
charger-limiting occurs at any load size.

All Models
All Models, except RV2012UL & RV3012OEM
Most models are factory preset to "Most Limiting". RV2012OEM is preset to "Less Limiting". RV2012UL and RV3012OEM models can only be set to "Most Limiting" or "Less Limiting" (B2
switch is non-functional).
Group B DIP Switches
Select AC Sharing—OPTIONAL
Your Inverter/Charger features a high-output battery charger that can draw a significant amount of AC power from your utility source or
generator when charging at its maximum rate. If your unit is supplying its full AC power rating to its connected heavy electrical loads at the
same time as this high charging occurs, the AC input circuit breaker could trip, resulting in the complete shut off of pass-through utility power.
To reduce the chance of tripping this breaker, all RV Inverter/Chargers may be set to automatically limit the charger output. This keeps the sum
of the unit’s AC load and charge power within the circuit breaker rating. This charger-limiting function has four settings, allowing you to
reduce the charger’s draw lower and lower, as needed, if the AC input circuit breaker keeps tripping under the normal AC loads of devices
you have connected downline from the unit. The figures show how to set your DIP Switches for charger-limiting.

* Most of your connected appliances and equipment will perform adequately when your Inverter/Charger’s High AC Input Voltage Point (DIP Switch #2 of Group A) is set to 135V and its Low AC Voltage Input Point (DIP Switches #3 and #4 of Group A are set to 95V. However,
if the unit frequently switches to battery power due to momentary high/low line voltage swings that would have little effect on equipment operation, you may wish to adjust these settings. By increasing the High AC Voltage Point and/or decreasing the Low AC Voltage Point, you
will reduce the number of times your unit switches to battery due to voltage swings.
