Tip: Not sure what you have? The solar panel’s label is usually found on the back. Controllers are typically inside the electronics bay.

Troubleshooting Steps

1. Determine Your System

• Locate your solar panel:
  Check the panel surface or edge for the brand and model.

• Find the charge controller:
  This is the small box where the panel wires enter your trailer—usually labeled “Renogy” or “Victron.”

• Battery monitor:
  Look for either a simple voltmeter, a Renogy display, or a round Victron BMV-712 gauge.

2. Check the Basics

• Panel plugged in?
  Make sure your solar panel cable is securely plugged into the exterior solar port.

• Trailer battery present and turned on?
  Some systems need the battery disconnect switch turned “on” for the solar to operate.

• Is the panel in direct sunlight?
  Shade, even partial, can prevent charging.

3. Check Panel Output (Open-Circuit Voltage)

• You’ll need a digital voltmeter/multimeter:
  Unplug the panel from the trailer and measure voltage at the panel’s connector.

• Expected voltages:

  • Bugout 130: 18–24 volts (full sun)

  • Lightleaf 140: 18–26 volts

  • Zamp 100: 19–22 volts (per panel)

• If voltage is much lower:
  The panel may be damaged, shaded, or dirty.

4. Check Wiring Continuity

• With panel plugged in:
  Use your voltmeter to check for voltage at the charge controller’s solar input terminals.

• No voltage:
  There may be a wiring or connection issue between the panel port and the controller.

---

5. Check the Charge Controller

• Renogy Wanderer/Rover Controllers:

  • Look for a small display or a row of LEDs.

  • The Rover MPPT features a digital display for system info.

  • Look for a green (charging) or red (fault) indicator.

  • Use the display or optional monitoring screen for charging status.

• Victron Controllers:

  • Check for a blinking green or blue light.

  • Download the VictronConnect app on your phone and pair via Bluetooth for detailed info.

  • Check for error messages or system faults in the app.

---

6. Check the Battery Monitor (if equipped)

• Renogy monitor:
  Should display battery voltage and charging amps.

• Victron BMV-712:
  Shows real-time charge/discharge amps and battery percentage.

---

7. Common Problems & Solutions

• No charge showing anywhere:
  Check all plugs, connections, and fuses. Try another known-good panel if possible.

• Controller shows error:
  Refer to your controller’s manual or app for fault codes and solutions.

• Panel voltage too low:
  Clean panel surface and re-test in direct sun. If still low, panel may need replacement.
