A4 Set Battery Charging Amps Type—OPTIONAL

Check specifications on for your unit’s high- and low-charging amp options. By setting on high charging, your batteries will charge at maximum speed and your RV 12V DC system loads will be well-supplied. When setting on low charging, you lengthen the life of your batteries (especially smaller ones).

*RV612ULH models have the “A4” DIP Switch set in the up position (high charge amps). RV612UL models have the “A4” DIP Switch set in the down position (low charge amps).

*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 or DIP Switch #3 for 612 models) 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.

B1 B2 Select Load Sharing—OPTIONAL (Not on 612 Models)

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 RVInverter/Chargers (except models RV612ULand RV612ULH) 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 func- tion 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 to deter- mine how heavy the connected load can be on your Inverter/Charger before charger-limiting begins.

All Models, except RV612UL & RV612ULH*

Select Battery Charger-Limiting Points—OPTIONAL (Not on 612 Models)

“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,

factory setting for RV1012UL models): 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.

All Models, except RV612UL, RV612ULH & RV1012UL*

“Least Limiting” (#B2 Down & #B1 Up, factory setting for all models except RV1012UL): 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 output at full load.

“No Limiting” (#B2 & #B1 Down): No

charger-limiting occurs at any load size.

*NOTE! RV612UL & RV612ULH models do not include these DIP Switches. There are only two limiting points available for RV1012UL models—"Most Limiting" and "Less Limiting"—which are determined solely by the position of the B1 DIP Switch (either up or down). The B2 DIP Switch on these models has no effect.
