Please take a moment to watch the video below for step-by-step guidance, or follow the step-by-step written directions.

If you need additional help, our After Sales team at Escape Trailer will be happy to assist you. You can submit a support ticket using this form. 

1. Locate Dinette Power Panel 

  • Start at the dinette where the main electrical panel is located.

 

2. Battery Disconnect (Red Key Switch)

  • Purpose: Controls whether the batteries are active.

  • Turn key ON (locked position) for normal use

  • Turn key OFF (removable position) for storage

  • If OFF: batteries will NOT charge from shore power

  • For long-term storage:

    • Turn battery disconnect OFF

    • Also turn OFF the DC breaker (see below)

 

3. Cold Start Button (Red Button)

  • Purpose: Helps restart system after long storage.

  • Use only if trailer won’t power up after being unused.

  • Cold start procedure:

Turn battery disconnect OFF

    • Turn DC breaker OFF

    • Turn inverter control (above fridge) OFF

    • Hold cold start button for a few seconds

    • Turn battery disconnect ON

    • Turn DC breaker back ON

      • (If it doesn’t work, check the small blade fuse next to it.)

 

4. Solar Controller (MPPT)

  • Located under the battery disconnect switch.

  • To view solar data on phone:

    • Download the Viron Connect app

    • Open app and search for your trailer name (usually last name + model number)

    • Select device

    • Enter Bluetooth PIN (on controller)

    • View live data (voltage, watts, battery status)

  • Optional settings (advanced users only):

    • Tap gear icon → Settings → Battery

    • Choose battery type (Lithium, Lead Acid, etc.)

    • Adjust charging settings if needed

  • Only trained users should change battery charging settings.

 

5. Servo GX System

  • Connects all electrical data systems

  • Sends info to touchscreen above fridge

  • App is optional (not required for normal use)

 

6. Breaker Panel (Right Side)

  • Solar Breaker (Trip Switch)

    • Push yellow button → disconnect solar panels

    • Use for maintenance

    • To reset: push switch back up

  • DC Disconnect Breaker

    • Turns off all 12V DC power flow

 

7. Smart Shunt

  • Automatically tracks battery usage and charging

  • No user action required

 

8. Inverter (Physical Unit)

  • Located in the dinette area

  • Leave switch ON normally

  • Controlled mainly by the panel above the fridge

 

9. Electrical Management System (Surge Protector)

  • Protects trailer from bad shore power

  • Detects:

    • High voltage

    • Low voltage

    • Wiring issues

  • Check error codes on the box if needed

 

10. Batteries (Under Dinette Bench)

  • Access:

    • Unscrew wing nuts

    • Lift cover panel

  • Battery care:

    • Lithium batteries are wired in parallel

    • Should be removed for winter storage

  • Winter storage steps:

    • Charge batteries to ~80%

    • Turn system off

    • Disconnect batteries

    • Store in room temperature area

  • Reassembly:

    • Reconnect as photographed

    • Replace cover

    • Tighten wing nuts securely

 

11. Digital Multi Control (Above Fridge)

  • This controls the inverter and shore power behavior.

  • Modes:

    • ON mode

      • Converts 12V → 120V power

      • Runs appliances like fridge, AC, outlets

      • Can use “Power Assist” (combines battery + shore power)

  • CHARGER ONLY mode

    • Uses shore power to charge batteries

    • Runs appliances only from shore power

    • Best for normal plugged-in camping

 

  • OFF mode

    • Inverter is off

    • Only 12V systems work

    • No 120V power unless on gas or shore power setup

 

12. Current Limit Setting (Important)

  • Controls how much shore power the trailer uses

  • How to set:

    • Match outlet rating (usually 30 amps)

    • If unsure, set slightly LOWER than breaker size

  • Power Assist feature:

    • If shore power is low (e.g., 8 amps):

      • Trailer uses shore power first

      • Batteries supply extra power when needed

 

13. Touchscreen Monitor (Above Fridge)

  • Key readings:

    • AC Input: Power coming from shore power

    • AC Load: Power being used by appliances

    • Battery status: Voltage, charge, amps

    • DC usage: 12V systems (lights, pump, etc.)

    • Solar (PV): Solar input (0 when indoors)

  • Battery signals:

    • Positive watts = charging

    • Negative watts = discharging

 

Quick Summary Flow

  • Normal Use:

    • Battery ON

    • DC breaker ON

    • Inverter ON or Charger Only

    • Plug into shore power if available

  • Storage:

    • Battery OFF

    • DC breaker OFF

    • Remove/store batteries (for winter)
