Voyager 20A PWM Waterproof Solar Charge Controller
Overview
The Voyager 20A is a compact IP67-rated PWM solar charge controller designed for outdoor off-grid systems.
It manages 12V and 24V battery banks (auto-detect for Gel/AGM/Flooded) and supports lithium batteries when you set the lithium profile manually.
Built-in 4-stage charging, temperature compensation, an LCD for status and error codes, and multiple protections keep your batteries healthy and your system reliable.
Benefits
Protects your battery life so you replace batteries less often and spend less time troubleshooting.
Keeps working outdoors in wet conditions so you can install it on RVs, boats, cabins, or other exposed locations with confidence.
Automatic 12V/24V detection (for non-lithium types) saves setup time and reduces configuration mistakes.
Temperature compensation helps maintain consistent charge performance in changing weather, so batteries charge correctly year-round.
Low self-consumption means the controller uses very little power itself, leaving more energy available for your loads.
LCD display and clear error codes let you diagnose issues quickly without guesswork.
Features
Smart PWM charging with 4-stage algorithm: Bulk, Absorption, Float, and Equalization.
IP67 waterproof enclosure suitable for exposure to water spray, rain, and condensation.
Supports 12V and 24V systems; automatically detects system voltage when connected to Gel, AGM, or Flooded batteries.
Manual lithium battery profile option — must set lithium parameters (voltage and profile) before charging lithium banks.
LCD screen for real-time status, accurate readings, and error codes.
Remote Temperature Sensor port and temperature compensation for precise charging based on battery temperature.
Multiple electronic protections: over-temperature, reverse polarity, over-voltage, and over-current protection.
Common positive ground configuration for easier system wiring in supported setups.
Compact, lightweight design for tight installations and mobile applications.
Recommended for parallel solar panel connections with PWM controllers to maintain PV voltage and controller efficiency.

Important Lithium Note: For lithium batteries, manually set the system voltage and battery type before charging. Failure to do so may prevent activation of over-discharged lithium batteries or cause improper charging.
Installation Notes:
Place the controller close to the battery to minimize voltage drop and wiring losses.
Do not install the controller inside a sealed enclosure with flooded batteries—gas buildup can create an explosion risk.
Check and tighten terminals regularly and avoid damaged wiring for safe, reliable operation.
When using PWM controllers, connecting solar panels in parallel is recommended to keep PV voltage within optimal range.
