Winnebago Sunstar 2023 ELECTRICAL User Manual

ELECTRICAL

Your motorhome is equipped with an electrical system consisting of two separate voltages:

• 12-volt DC system (battery current); and 120-volt AC system (household current) The 12-volt system consists of two internal power sources, while the 120-volt system is operated from an outside power source or the optional 120-volt generator.

when the auxiliary electric generator is running, the power converter automatically changes a portion of the 120-volt current to a 12-volt DC current. All equipment in the motorhome that is normally powered by the house batteries is then powered through the converter. In addition, the following equipment is entirely dependent on the 120-volt current: air conditioner, microwave oven, and any 120-volt electrical equipment used at convenience outlets.

ELECTRICAL CAUTIONS

• Careless handling of electrical components can be fatal. Never touch or use electrical components or appliances while feet are bare, while hands are wet, or while standing in water or on wet ground.
• Improper grounding of the vehicle can cause personal injury. Do not plug the utility power cord into an outlet that is not grounded and do not adapt the plug to connect to a receptacle for which it is not designed.
  Do not attach an extension cord to the utility power cord.
• Be sure that all electrical appliances to be used contain 3-prong plugs for proper grounding.
  Avoid overloading electrical circuits. Replace fuses or circuit breakers with those of the same size and amperage rating only. Never use a higher-rated fuse or breaker.
  Use caution when handling or working near electrical storage batteries. Always remove the jewelry and wear protective clothing and eye covering. Avoid creating sparks.

ELECTRICAL SYSTEM – HOUSE 120-VOLT AC

The 120-volt system operates from the shoreline cord connected to an outside 120-volt utility service, such as those at campgrounds or from the 120-volt generator. When the shoreline cord is connected to an outside power source, or when the auxiliary electric generator is running, the power converter automatically changes a portion of the 120-volt current to 12-volt DC current. All equipment in the motorhome that is normally powered by the house batteries is then powered through the converter.
In addition, the following equipment is entirely dependent on the 120-volt current: air conditioner, microwave oven, and any 120-volt electrical equipment used at convenience outlets.

POWER CORD – EXTERNAL

(Shoreline)
The external power cord (commonly referred to as a “shoreline”) is stored in the utility compartment on the left (driver’s) side of the motorhome.

WARNING
Do not use an extension cord. Improper-sized cords, damaged cords, and poor connections can lead to fire, which can result in death or serious injury.

WARNING
Do not connect the external power cord to any receptacle until you have verified proper polarity and grounding. Be sure all prongs of the supply cord are properly plugged into the receptacle. Failure to observe can result in death or serious injury.

The power cord is designed to ground the electrical system through the receptacle. It is also designed to carry the amperage output of most campground outlets. If the electrical receptacle to be used is designed to mate with the prongs of the power cord plug, the electrical connection can be expected to carry a rated load.

Connecting the Power Cord
To connect to an external source, remove the cord from the utility compartment and plug it into a suitable power outlet to provide external power to the motorhome and converter/charger system.
Your motorhome may be equipped with either a standard 30-amp system or an optional 50-amp system.

NOTE: Some parks do not have 50-amp service  available, so you will need to connect to a standard 30-amp service pole using an adapter.
If your motorhome is equipped with a standard 30-amp system, you cannot connect to a 50-amp service. Do not use adapters to connect 30-amp systems to a 50-amp service or you may cause an overload on electrical system components.

30 Amp Receptacle

WARNING
This connection is for 110/125 Volt AC, 60 Hz 30 Ampere supply.
Do not exceed circuit rating. Exceeding the circuit rating may cause a fire and result in death or serious injury.

WARNING
This connection is for 208Y/120-Volt or 120/240 Volt AC, 3-pole, 4 wire, 60 Hz 50 Ampere supply.
Do not exceed the circuit rating. Exceeding the circuit rating may cause a fire and result in death or serious injury.

An access cover in the compartment floor lets you route the shoreline cord through a passage in the bottom of the compartment so you can shut the compartment door while the shoreline is connected (Typical Views shown).

Rotate the access cover counter-clockwise (left) to unscrew and remove the cover.

1. The Power Cord can now be routed through the hole. To replace the access cover, make sure it is free of any obstructions then screw the access cover back in clockwise (to the right).
   The power cord is designed to ground the electrical system through the receptacle. It is also designed to carry the amperage output of most campground outlets. If the electrical receptacle to be used is designed to mate with the three prongs on the power cord plug, the electrical connection can be expected to carry rated load.

WARNING
Service inlet access must be closed when utility connections are not in use.

Park Fuses or Breakers
Most campgrounds are equipped with a fuse or circuit breaker at the receptacle (which we recommend shutting off before engaging or disengaging the power cord.) This protects the park’s wiring, as well as the power cord on your vehicle from electrical damage. If electrical power fails, contact the park attendants and have them check the fuse or breaker for your supply receptacle.

INVERTER UNIT – 1000W

The inverter changes 12-volt DC battery power into 120-volt AC power for use by 120-volt AC equipment inside the motorhome. The inverter unit is located inside an interior cabinet.
NOTE: Batteries will deplete with use of the inverter.
Monitor battery levels regularly when not connected to shoreline or generator power.

The inverter can also be used while driving the motorhome because the engine alternator will charge the batteries while driving.

The inverter has built in GFCI protection. The GFCI will protect against electrical shock by interrupting the flow of electricity. If there is no power from the inverter the GFCI may have tripped. Reset the GFCI by pressing the RESET button. If the GFCI continues to trip, have the electrical system checked and repaired, if necessary, before using the inverter again.

CIRCUIT BREAKERS – HOUSE 120-VOLT AC

The breaker panel protects all 120-volt components in the motorhome from either an overload on the circuit or a shortage in the wiring or component itself. When an overload or short develops, the breaker will open preventing damage to the system. Shut off the equipment (for example the roof air conditioner) and allow a brief cooling period. Then reset the breaker by moving the switch to “Off” and back to “On”. If the breaker is continually tripped and no overload is evident, have the system checked for a short in the wiring or the appliances. The breaker panels are located behind a door or pull-off panel on a lower cabinet face in either the galley or lounge area or beneath the rear bed, depending on the model.

NOTE: Breakers are labeled on the panel.
The arrangement may vary according to appliance and equipment options.

ELECTRICAL OUTLETS – HOUSE 120-VOLT AC

A number of standard household electrical outlets are provided throughout the motorhome for connecting small appliances such as televisions, radios, toasters, etc.
An exterior outlet is also located in the rear storage compartment on the passenger side of the motorhome.

GROUND FAULT CIRCUIT INTERRUPTER

Bath, galley, and exterior outlets are connected to a GFCI (Ground Fault Circuit Interrupter), which is an extremely sensitive circuit breaker that will help to protect against severe electrical shock if a ground fault develops. If such a condition occurs, the GFCI will break the circuit by turning off the power to the protected outlets. Should this occur, unplug all the appliances on that circuit and press the reset button on the GFCI-equipped outlet.
If the GFCI keeps tripping, have the electrical system checked and repaired, if necessary, before using again.

GFCI Outlet
(Ground Fault Protector)

WARNING
The GFCI will not completely eliminate the risk of electrical shock. Infants and small children may still be affected.

ELECTRICAL GENERATOR – 120-VOLT

–If Equipped.

WARNING
Careless handling of the generator and electrical components can be fatal. Never touch electrical leads or appliances when your hands are wet, or when standing in water or on wet ground. Do not attempt to repair the generator yourself. Service should be performed by a qualified service center.

To use the 120-volt generator, plug the power cord into the generator receptacle within the utility compartment before starting the generator.

WARNING
Do not plug the power cord into the generator receptacle while the generator is running. Electrical shock can cause personal injury.

Automatic Power Transfer Switch

(available with 50-amp service only)

–If Equipped
Whenever the generator is needed, an automatic power transfer system automatically switches the household electrical system to the generator 30 seconds after the generator is started. The 30 second delay allows the generator to start easily without the burden of electrical loads.

Operation Warnings and Cautions

WARNING
The exhaust of all internal combustion engines contains carbon monoxide (CO). This poisonous gas is colorless, odorless, tasteless, and lighter than air. The exhaust systems of both your motorhome engine and your generator engine have been installed with your safety in mind. However, certain precautions must be taken when using them to protect yourself from conditions beyond the control of the manufacturer.

1. Do not simultaneously operate the generator and a power vent, which could draw exhaust gases into the vehicle.
2. Do not open windows or vents on the end or side of the vehicle where exhaust pipe of the generator is located.
3. Park the vehicle so that the wind will carry the exhaust away from the vehicle. Also, note the position of other vehicles to be sure their exhaust will not enter your vehicle.
4. Do not operate the generator engine while parked if vegetation, snow, buildings, vehicles, or any other object can deflect the exhaust under or into the vehicle.

NOTE: Check auxiliary generator oil level frequently during periods of use.
Refer to the generator manufacturer’s maintenance information in your InfoCase for specific recommendations.

Automatic Generator Start (AGS)

-If Equipped
The Automatic Generator Start feature monitors house battery voltage and motorhome interior temperature, and has the ability to automatically start the Generator to help maintain full air conditioning function and house battery charge.

WARNING
Do not run the Genset or use the Automatic Generator Start feature in
“Enabled” or “Quiet” modes when the RV is indoors or a combined space. Asphyxiation or carbon monoxide poisoning hazards exist whenever Genset exhaust gases can accumulate.

WARNING
The Automatic Generator Start Feature is not a life support system. It can stop without warning. Children, persons with physical or mental limitations, and pets could suffer personal injury or death. A personal attendant, redundant power or alarm system must be used if Genset operation is critical.

The Automatic generator Start feature requires an electrical safety signal input. The input is triggered when the vehicle is put in Drive and reaches a speed above 0 mph. When the vehicle is driven the AGS becomes “Locked Out” if it were previously set to Auto Operation. The AGS can once again be manually enabled once the vehicle has stopped and in a safe location. Access the screen where the “Clear Locks” button is displayed and press before being able to Enable the AGS and restore the previous settings.
The following label is located near the 120-volt house circuit breaker panel and at the Generator to warn you to disconnect specific electrical connections before servicing the Generator and storing the motorhome.

Quiet Time

Quiet Time is used in the event that there is a period of time during the day that generator use is not allowed or desired.
This is typical for motorcoach conventions and some RV parks. If any auto generator Start feature tries to start the generator during the time period between quiet time begin and quiet time end, the system will not allow the generator to start regardless of a feature being enabled and calling for the generator to run.

Auto-charger

The Auto-charger feature is used to maintain house battery charging automatically while dry camping, or storage. The Auto-charger constantly monitors the voltage of the batteries, and when needed, starts the generator allowing the battery charger to charge the batteries. In most cases, the system monitors the battery information via the inverter/charger. In some (in particular after-market installations), the voltage is monitored directly via the Connected Coach system. In all cases either the inverter/charger or battery charger has to be enabled to charge the instant that 120V electricity is applied to the coach, either from the generator or shore power cord. Otherwise no charging to the batteries can occur.

Battery Functions

This battery is Bluetooth-compatible. Monitor battery voltage, state-of-charge, temperature, current and status code remotely from your mobile device. Download in IOS at the Apple App Store or for Android download in Google Play.

Reserve Voltage Cutoff (RVC)
NeverDie® function. During discharge, the BMS will disable the discharge current when the battery voltage reaches the RVC level, which allows the battery to store a small energy reserve. Once the battery is in the RVC state you can access the reserve capacity by a short press of the Power button.

Low Voltage Cutoff (LVC)
During discharge, the BMS will disable the discharge current when the battery voltage reaches the LVC level. Charging current is allowed so that the battery can be charged by activating a charging source. Some charging sources require to “see” the battery voltage before allowing charging, in which case LVC lockout can be temporarily overridden by holding down the Power button. This override will allow the charger to sense the battery voltage, so charging can begin.

High Voltage Cutoff (HVC)
During charging, the BMS will disable the charge current if the battery voltage reaches the HVC voltage level. This should not happen during normal operation if charging sources are set up with the correct voltage levels. Once the charge current is removed, the battery voltage will slowly lower to a resting level, typically 13.6V. If your charging source has a “float” mode, it should be set to 13.6V.

Temperature Based Cutoff
When the internal battery temperature goes below or above the preset safe limits the BMS will disable charge or discharge current to prevent further use of the battery until the temperature returns to safe operating limits. Different temperature limits are enforced for charging and discharging due to the nature of Lithium chemistry. Discharge safe range is -4°F to 131°F, charge safe range to 32°F to 113°F.

Over Current Protection
The BMS will disable discharge or charge current if the current/amperage value exceeds the preset thresholds. To restore normal operation, remove/address the source of the overload, then short-press the Power button.

Short Circuit Protection
The BMS will immediately disable the discharge current if the current value exceeds 1000A. To restore normal operation, remove/address the source of the short circuit, then short-press the Power button.
NOTE: The lithium battery is capable of significant power output and may maintain the voltage level during a short circuit event, producing a very large current, capable of melting or welding connection points and damaging cables and connectors. Even when the BMS detects the short circuit and tries to open it, the BMS switch itself might weld under such large current. Make sure the battery connection is always properly fused and does not rely on the BMS alone for short-circuit protection.

250 Amp circuit breaker
The 250 amp circuit breaker is located in the passenger’s side compartment next to the entry door.
The circuit breaker is a secondary protection device that works in unison with the battery BMS.

NOTICE
Shutting off lithium batteries or circuit breaker with engine running can result in component malfunction.

ELECTRICAL SYSTEM – HOUSE 12-VOLT DC

The DC voltage system consists of the chassis battery, the 12-volt house batteries, and the 12-volt power converter.

Converter
See “Converter” previously in this section.

Chassis Battery
The chassis battery is used to operate the engine starter and automotive accessories and controls found on the instrument panel. The electric step is also connected to the chassis battery.
Refer to your chassis manual provided in your InfoCase for further information on chassis batteries and chassis electrical system.

House Batteries
House batteries are “deep-cycle” type batteries specially designed for recreational vehicle use. They will provide longer lasting power than standard automotive starting batteries and will withstand the frequent drain-and-recharge cycles that occur under the demanding conditions of a camping outing.
The house batteries supply power to 12-volt equipment located in the living area of the motorhome. This includes the following 12-volt powered components (if equipped): interior 12-volt lighting, range exhaust fan, propane furnace fan, fresh water pump, systems monitor panel, refrigerator, roof vent fans, and 120-volt electrical generator starter.
The house batteries can also provide emergency power to start the engine if the chassis battery is discharged. (See “Battery Boost Switch” in Section 3 – Driving Your Motorhome).
House batteries are automatically charged by the chassis alternator while the engine is running.

HOUSE/COACH BATTERY DISCONNECT SWITCH

(COACH BATT)
The House/Coach Battery Disconnect switch lets you disconnect the house batteries from the 12-volt system of your motorhome during storage periods to avoid battery drain by electrical items that are hooked directly to the house batteries, such as clock displays and radio memories, etc. Always leave this switch ON when the vehicle is in motion or in use.

NOTE: Some electronic displays and memory functions may need to be reset after power has been reconnected.
Batteries will only be charged by the converter when on shore power if the disconnect switch is ON.

NOTE: The House/Coach Battery Disconnect Switch will illuminate green whether the disconnect switch is in the on or off position when connected to shore power.
See also “Battery Care” elsewhere in this section.

CAUTION
Step cover must be closed and latched. Failure can cause injury.

BATTERY CARE

Lead-acid type batteries are electrochemical devices for storing and releasing electrical charge. As such, they are simply an electrical reservoir, not an electrical source. As soon as energy is removed from the battery, it should be replaced by the engine alternator or the motorhome converter system. If a battery sits unused for 30 days or more, especially during warm weather, it can develop a deposit of sulfate crystals on the metal plates inside the battery. This condition is called “sulfating” and prevents the battery from either releasing or accepting a charge. If this condition occurs, the battery must be replaced.
If a battery does not contain at least 80% charge during freezing temperatures, the electrolyte can freeze and crack the battery case.

The two best defenses against sulfating and insufficient charge are to:

1. Turn off the House/Coach Battery Disconnect switch to avoid parasitic discharge (the trickle discharge caused by directly connected components like propane gas detectors or digital clock displays, etc.)
2. Check the battery and recharge as necessary at least once a month during long storage periods. Turn the House/Coach Battery Disconnect switch off to avoid electrical arcing when attaching or detaching charger clamps.

NOTICE
Disconnect batteries before connecting external charging equipment to avoid damage to sensitive electronic components.

WARNING
This vehicle, like other vehicles, may contain small amounts of one or more substances which are listed by the state of California for causing cancer or reproductive toxicity.

WARNING
California Proposition 65 Warning: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the state of California to cause cancer and reproductive harm. Wash hands after handling.

NOTE: Do not leave the shoreline plugged in during storage. Follow regular battery inspection and maintenance.

Further precautions are:

1. Check the state of charge periodically to avoid discharge or sulfating.
2. To ensure that the battery will always accept and hold a charge, follow these simple maintenance practices:
3. Make sure the batteries always remain securely clamped in the battery tray.
4. Make sure battery cable clamps are tight on the terminal posts and are free of corrosion.
5. Neutralize corrosion buildup or acid film on top of battery by washing with a baking soda/water solution. Rinse with clear water.

NOTE: Make sure vent caps are on securely to prevent baking soda solution from entering the battery and contaminating the electrolyte fluid.

WARNING
Before removing any battery cables or battery, make sure all 12-volt equipment in the motorhome is off and the power cord has been disconnected. Be sure to replace the battery terminal boot, if supplied, back onto the positive terminal after servicing. Care must be taken to avoid pinching the cable between any metal parts. Should the cable be damaged, a short circuit could result in personal injury or damage to equipment. Replace any damaged cables at once. Always remove the jewelry and wear protective clothing and eye covering when checking or handling batteries.

• Clean and tighten battery terminals and have the specific gravity checked at least once a year.
  Check the battery fluid level every month, or more often in hot weather. Fill to approximately 3/8 inch above the plates. DO NOT OVERFILL. If the fluid is added during freezing weather, the motorhome should be driven several miles to mix water and electrolyte to prevent freezing. Fluid level check may be omitted if equipped with maintenance-free batteries.

WARNING
To prevent wiring damage, it is essential when replacing the cables on the battery, or when using a “booster” battery, that the positive post and the positive cable be attached and the negative post and negative cable be attached. The posts are marked (+) plus and (-) minus. If a “boost charger” is used while battery is in the motorhome, disconnect both battery cables before connecting the charger to avoid damage to engine electronic components. Never attempt to charge or boost a frozen battery. An explosion can occur resulting in personal injury.

Chassis Batteries
If your motorhome is going to be unoccupied for two weeks or more, Winnebago Industries® recommends disconnecting the chassis batteries in your motorhome to avoid battery discharge.
Turn the Chassis Battery Disconnect switch (located near the entrance door) to the OFF position to disconnect batteries.

CIRCUIT BREAKERS AND FUSES – HOUSE 12-VOLT DC

All 12-volt circuits and equipment in the coach area of the motorhome are protected by either a fuse panel or breaker panel. When a circuit is overloaded or a short develops in any part of the system, a fuse or breaker will shut down that circuit. If this happens, turn off all affected lights or appliances and reset the breaker or replace the fuse with a new one of equal amperage rating.

House 12-Volt Circuit Breakers
A label on the panel states the amperage rating and circuit protected for each breaker.
The circuit breaker panel is located behind a door or pull-off panel on a lower cabinet face in either the galley/lounge area or beneath the rear bed, depending on model.
