Troubleshooting Power Issues in Your nuCamp RV


If some of the electrical components in your RV are not working, the issue may be related to either your 12-volt (DC) system or your 120-volt (AC) system. Follow the steps below to help identify and resolve common power problems. 


If Your 12-Volt Battery Powered Items Are Not Working 


The 12-volt system powers many essential components in your RV, such as lights, fans, the water pump, and certain appliances. If these items are not working, try the following checks: 

  1. Check the Battery Disconnect Switch Locate your battery disconnect switch and make sure it is in the green or ON position. If the switch is off, your camper will not receive power from the battery.
  2. Inspect the Main DC Breaker Some models include a main DC breaker that protects the 12-volt system. Make sure the breaker has not tripped. Note that some models, such as the TAG or TAB 320, may not have this breaker. 
  3. Check the Fuses in the Power Distribution Panel Open your power distribution panel and inspect the fuses. Look for any blown fuses. Replace any fuse that appears damaged or burned. 
  4. Inspect the Battery Terminal Fuses Check the fuses connected to the positive terminal of your battery. A good fuse should look intact inside. If the fuse appears burned, melted, or broken, it will need to be replaced. 


If Your 120-Volt Power Is Not Working While Plugged In 


The 120-volt system powers outlets and appliances when your RV is connected to shore power. 

  1. Verify the Power Source First, confirm that the outlet you are plugged into has power. An easy way to check is to plug in another device, such as a space heater or a phone charger. If the device does not power on, the outlet itself may not be providing electricity. 
  2. Reset the Circuit Breakers Sometimes a breaker can trip without appearing obviously switched off. To reset them, turn all breakers completely off then turn them back on. 
  3. Reset the GFCI Outlet Look for a GFCI outlet, which has a reset button on the face of the outlet. Press the reset button to restore power. Even if the outlet that is not working does not have a reset button, it may be connected to another GFCI outlet nearby, so check other outlets in the camper. 


Still Having Trouble? If you have tried all of these steps and your electrical system still isn’t working properly, it may be time to contact your dealer or service center for additional assistance. Or you can contact our team at tech@nucamprv.com.


Understanding Your Battery Disconnect Switch

What Is the Battery Disconnect Switch?

The battery disconnect switch is an essential safety feature in your teardrop trailer or truck camper. Its primary function is to control the power flow from your RV battery, allowing you to isolate the battery from the system when needed. This switch helps preserve battery life by preventing unnecessary drain from low-voltage appliances.



On or Off? Understanding the Positions

  • Green Position (ON): The battery is connected and actively supplying power to your RV.
  • Red Position (OFF): The battery is disconnected and not powering your RV.

When to Turn Off the Battery Disconnect Switch

  1. During Storage – Appliances like the fridge and radio can draw power even when your RV is not in use, leading to gradual battery depletion. According to Battle Born, the best way to store lithium batteries is to fully charge them and then disconnect them. These batteries do not require trickle charging or maintenance while in storage. 
  2. During Maintenance or Repairs – Turning the switch to red ensures that power is cut off, minimizing the risk of encountering live wires when working on your RV.

When to Keep the Battery Disconnect Switch On

  1. When Using Your RV – If you need power for lights, appliances, or other systems, make sure the switch is in the green position.
  2. While Charging on Shore Power – If you’re plugged into shore power and want to charge your battery, the switch must be set to green. Otherwise, the battery won’t charge.
  3. During Travel – Keeping the switch on allows the battery to charge while towing.

Locating the Battery Disconnect Switch on Your nuCamp RV

The location of the switch varies by model and year. Here’s where you can find it on 2024 nuCamp models:

  • TAG & TAG XL – Front tub
  • TAB 320 S & CS-S – Inside the door, at the base of the dinette
  • TAB 400 – Exterior storage compartment on the passenger side
  • Barefoot – Under the driver’s side cushion
  • Cirrus 620 – Behind a panel in the dinette
  • Cirrus 820 & 920 – On the step leading to the bed

Final Thoughts

The battery disconnect switch is a simple yet powerful tool that enhances safety, preserves battery life, and ensures efficient power management in your RV. By understanding when and how to use it, you can maximize your battery’s lifespan and enjoy a hassle-free camping experience.

Can I Run Everything in My Trailer Off My Battery?

When it comes to powering your nuCamp RV, it’s essential to know which appliances run on battery power and which require a 110V (shore power) connection. Below, we break it down by unit to help you better understand your power options.


TAG

  • All appliances can operate without 110V power except for the air conditioner, electric space heater, and microwave.
  • Standard 110V outlets will not work unless the trailer is plugged into shore power.
  • If you're boondocking, you’ll need to connect your trailer to a generator to power the A/C unit, electric space heater, and all 110V outlets.
  • The stove requires propane (LP) and 12V power to operate.

TAB Series

  • Like the TAG, all appliances function without 110V power except for the A/C and microwave.
  • Standard 110V outlets require shore power to operate.
  • If boondocking, a generator is needed to power the A/C and 110V outlets.
  • The fridge can run on battery power, as can the fans, lights, TV/radio, and 12V/USB outlets.
  • The Alde heating system requires 12V power and propane to function when boondocking off-grid.
  • The stove runs on propane.

Cirrus Truck Campers

  • Similar to the TAB, all appliances can operate without 110V power except for the A/C and microwave.
  • 110V outlets require shore power or a generator to function.
  • When boondocking, a generator is necessary to run the A/C and 110V outlets.
  • The fridge, fans, lights, TV/radio, and 12V/USB outlets can all run off the battery.
  • The Alde system requires both 12V power and propane when boondocking off-grid.
  • The Cirrus 920 has an on-board inverter that can be used to power the 110V outlets even when off-grid. The Cirrus 820 has a small inverter to run the television & bed outlet (for a CPAP machine).


Final Thoughts

Understanding your RV’s power system ensures a smooth and stress-free camping experience. Whether you're plugged into shore power or venturing off-grid, knowing how each appliance operates will help you stay prepared.

Understanding the Victron SmartShunt


The Victron Bluetooth SmartShunt Battery Monitor is a powerful tool that helps you keep track of your camper’s battery health and performance. It comes standard in many nuCamp models. 


Below, we’ll walk you through where to find it, what it does, and how to use it. 


Where to Find the Victron SmartShunt 

The location of the SmartShunt can vary depending on your camper model and year. For example, in the 2025 TAB 320, you’ll find the SmartShunt beneath the passenger-side dinette. 


To identify it, look for: 

  • Two large brass terminals 
  • Multiple wires are connected to the system side 
  • A single wire running to the battery 


Accessing Battery Info with the VictronConnect App 

The SmartShunt doesn’t have a built-in display, but that’s where the VictronConnect app comes in. You can download this app for free on iOS and Android devices. 


With the app, you can monitor key details about your battery, including: 

  • State of charge (SOC) → The estimated percentage of remaining battery power 
  • Battery voltage → The current voltage level of your battery 
  • Amperage flow → How many amps are flowing into or out of the battery 


Why It Matters 


Keeping an eye on your battery’s status is essential when camping off-grid. Knowing whether you’re charging (gaining energy) or discharging (using energy) helps you: 

  • Plan power usage more efficiently. 
  • Avoid draining your battery unexpectedly. 
  • Extend the life of your battery system. 


Summary 


The Victron SmartShunt is a simple but powerful tool that, combined with the VictronConnect app, gives you real-time insight into your camper’s electrical system. Make sure to check the app regularly so you can manage your power wisely and enjoy worry-free camping. Contact tech@nucamprv.com with any questions. Happy Camping!
