Renogy New Edition Voyager 20A PWM Waterproof Solar Charge Controller

Designed for outdoor, off-grid solar installations, the Voyager 20A PWM Waterproof Controller optimizes battery protection and charging efficiency in wet environments. With its IP67 rating, it remains reliable against water spray, rain, and condensation, making it ideal for marine, RV, cabin, or rooftop solar systems exposed to the elements.

Key features and performance

• 4-stage charging: Bulk, Absorption, Float, and Equalization to extend battery life and ensure safe, stable charging.
• Rated charge current: 20A; supports 12V and 24V systems with automatic detection for non-Lithium batteries.
• Battery compatibility: Gel, AGM, Flooded; Lithium option requires manual voltage setting for optimal charging.
• PV input range: 15–55V; Max PV open-circuit voltage: 12V@25V, 24V@55V.
• Low self-consumption: 0.22W/h in a 12V system (≈1.92 kWh/year), preserving battery capacity during idle periods.
• Remote temperature sensor port for real-time measurement and precise temperature compensation.
• Common Positive Ground design to simplify multi-battery configurations and enhance safety.

Safety, protections, and certifications

• IP67 waterproof enclosure provides protection against dust and water ingress.
• Built-in protections for PV panel, battery, and controller guard against overcharge, over-discharge, short circuits, and reverse currents.
• Operating temperature range: -31°F to 113°F; storage: -31°F to 167°F; humidity: 10–90% non-condensing.
• Important caution: Do not install the controller in a sealed enclosure with flooded batteries due to gas risk; install as near the battery as possible to minimize wiring losses.

Installation and maintenance

Compact and lightweight (0.55 lb) with dimensions about 3.84" H x 6.08" W, the Voyager 20A fits tight spaces and small enclosures. For lithium batteries, manually set the charging voltage to ensure proper charging. If using PWM in a system, connect solar panels in parallel to maintain PV output voltage for optimal efficiency. Regularly inspect wiring connections and keep the unit away from moisture and ignition sources.

 

The Voyager 20A is a top-tier 20-amp charge controller, rated IP67, making it perfect for outdoor use in conditions involving water spray, rain, and condensation. Featuring advanced PWM technology, it supports both 12V and 24V off-grid applications and is compatible with four different battery types, including Lithium Iron Phosphate. With built-in protections for the solar panel, battery, and controller, the Voyager 20A ensures the longevity of your system. PLEASE NOTE: For lithium batteries, it is essential to manually set the voltage for optimal charging.

Note: Please set the voltage manually to charge lithium batteries.

Efficient, Stable, and Safe Charging

Leveraging intelligent PWM technology, the Voyager 20A offers 4-stage charging (Bulk, Absorption, Float, and Equalization) to protect the battery. It also includes multiple electronic protections for the battery, controller, and PV system, ensuring safe and efficient charging and usage.

Compact and lightweight

The Renogy Voyager PWM Waterproof Controller is compact and lightweight, making it perfect for applications with limited space. With a weight of only 0.55lb, a height of 3.84 inches and a width of 6.08 inches, this controller is ready to be installed in small spaces.

Common Positive Ground

The Voyager PWM Waterproof Controller is a common positive ground charge controller, beneficial in ensuring charging safety.

Temperature Monitor and Compensation

Equipped with a Remote Temperature Sensor Port, the Voyager 20A measures battery temperature in real-time and uses this data for precise temperature compensation, ensuring stable and consistent charging performance.

Extremely Low Self-Consumption

In a 12V system, the Voyager PWM Waterproof Controller consumes just 0.22W/h or 1.92kWh per year (365 days), making it highly energy-efficient while effectively charging your battery.

Automatic Voltage Detection

The Voyager PWM Waterproof Controller supports both 12V and 24V systems and automatically detects system voltage when connected to Gel, AGM, or Flooded battery banks. REMEMBER: For lithium batteries, please manually set the voltage to ensure proper charging.

NOTE

• For users with a PWM controller in their solar system, we highly recommend connecting the solar panels in parallel. This setup helps maintain the PV output voltage, allowing the controller to operate at optimal efficiency.
• Never install the controller in a sealed enclosure with flooded batteries as gas can accumulate and there is a risk of explosion.
• The solar controller should be installed as near the battery as possible to avoid efficiency loss.
• Incorrectly setting the battery type on the controller may damage your battery. The system's auto-recognition feature is only compatible with Gel, AGM, and Flooded batteries. When using the Voyager to charge a lithium battery bank, make sure to manually set the system voltage. Otherwise, an over-discharged lithium battery may not be activated.
• To ensure optimal controller performance, avoid any damage or wear to the wires connected to the controller. Ensure all terminals are tightly secured, and regularly inspect for loose, broken, or burnt connections. It is a good idea to sporadically clean the controller’s case with a damp cloth to keep it in good condition.
