Renogy COMPACT-SUITCASE 220 User Manual

The Renogy COMPACT-SUITCASE 220 is a portable, foldable 220W solar panel kit designed for off-grid power generation. It features high-efficiency monocrystalline solar cells, a built-in kickstand, a waterproof 20A PWM charge controller with LCD display, integrated carrying handles, and all necessary cables for quick setup. Ideal for RVs, camping, boats, and emergency backup. Below are key sections for safety, features, installation, setup, operation, maintenance, and troubleshooting.

Features at a Glance

Key components: Two 110W monocrystalline solar panels, 20A PWM Charge Controller with LCD, MC4 Connectors, 10ft Tray Cables, Battery Clamps, Built-in Kickstand, Carrying Handles.

Installation

Unpack and inspect all components. Choose a sunny, open location.

1. Unfold the suitcase: Lay flat and extend the built-in kickstand.
2. Position for sun: Adjust kickstand to face panels directly toward the sun.
3. Connect panels to controller: Use pre-connected MC4 cables between panels and controller.
4. Connect to battery: Attach battery clamps (red to positive, black to negative) to your 12V battery.
5. Secure cables: Keep cables away from sharp edges and foot traffic.

WARNING! Do not install near flammable materials. Ensure battery is in a well-ventilated area. Avoid shading on panels.

First-Time Setup

Once physically installed, configure the charge controller.

1. Verify connections: Ensure all MC4 connections are secure and battery clamps are tight.
2. Power on: The LCD display on the controller will illuminate, showing battery voltage.
3. Select battery type: Press the MODE button on the controller to cycle through battery types (Sealed, Gel, Flooded, User). Match to your battery.
4. Check charging status: The display will show "Charging" icon and current (Amps) when panels are in sunlight.
5. Optimize angle: Adjust kickstand throughout the day for maximum sun exposure.

CAUTION! Always connect battery first, then solar panels. Disconnect in reverse order (panels first, then battery).

Controls and Settings

Primary control is via the 20A PWM charge controller's buttons and LCD display.

Controller Buttons: MODE (select battery type/parameters), ON/OFF (power).

LCD Display Icons: Battery voltage (V), Charging current (A), Battery type icon, Charging status (Bulk/Absorption/Float), Fault indicators.

Battery Type Settings: Sealed (default), Gel, Flooded, User (custom voltage). Use MODE button to select.

Protection Settings: Factory pre-set for over-voltage, under-voltage, reverse polarity, short circuit, and over-temperature.

Connecting to Batteries

Compatible with 12V lead-acid batteries (AGM, Gel, Flooded). Not for lithium batteries without a compatible controller.

1. Ensure battery is 12V and in good condition.
2. Turn OFF the charge controller using its button.
3. Connect battery clamps: RED clamp to battery POSITIVE (+) terminal. BLACK clamp to battery NEGATIVE (-) terminal.
4. Turn ON the controller. The LCD should show battery voltage.
5. Expose solar panels to sunlight. The "Charging" icon and current reading should appear.

Tip: For multiple suitcases, you can connect in parallel using MC4 branch connectors (not included). Do not exceed the controller's 20A input limit.

Operation & Monitoring

Daily operation is largely automatic once set up.

1. Deploy: Unfold suitcase, set kickstand facing the sun.
2. Monitor: Check LCD for:
   • Battery Voltage (e.g., 12.5V - 14.4V during charging)
   • Charging Current (Amps) - varies with sunlight intensity.
   • Charging Stage: Bulk (constant current), Absorption (constant voltage), Float (maintenance).
3. Adjust: Reposition panel angle every few hours for best performance.
4. Disconnect: When not in use, or for storage, press controller OFF, disconnect battery clamps, then fold suitcase.

WARNING! Do not attempt to disassemble the panels or controller. Do not touch live terminals with wet hands.

Safety Features

Built-in protections: Overcharge, Over-discharge, Reverse Polarity, Short Circuit, Over-temperature. The controller will automatically cut off charging if battery voltage is too high or too low.

Care & Storage

Clean panels with a soft, damp cloth. Do not use abrasive cleaners. Store in a cool, dry place when not in use. Fold carefully and secure latches. Disconnect from battery for long-term storage.

CAUTION! Do not step on or place heavy objects on the panels. Keep the controller dry; while IP65 rated, avoid submersion.
