RCC20VOYP - Renogy New Edition Voyager 20A PWM Waterproof Solar Charge Controller, 20 Amp

• 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.
