Samlex Solar Charge Controller - 12V - 8A

The Samlex Solar Charge Controller – 12V – 8A is purpose-built for anglers and boaters who rely on auxiliary solar power systems to extend time on the water without shore power. This charge controller is specifically designed for 12V systems, making it ideal for running a trolling motor, fish finder, GPS, or cabin lighting on extended trips.

This compact controller regulates power flow from your solar panels to your 12-volt battery bank, preventing overcharge and extending battery lifespan. Built by Samlex America, a leader in marine-grade DC power products, this 8-amp charge controller features PWM (pulse-width modulation) technology to optimize charging cycles and minimize voltage fluctuation. The unit automatically regulates solar panel input, protecting your batteries from damage caused by overcharging while improving overall system efficiency.

At just 0.4 pounds and measuring 3 × 2 × 5 inches, it mounts easily in engine compartments, cabin spaces, or battery enclosures with minimal footprint—a critical advantage on boats where space and weight are precious commodities. The compact design doesn't compromise durability; marine-grade construction ensures it withstands vibration, humidity, and corrosive salt-air exposure. This charge controller works best for boats with modest solar arrays (up to 96 watts at 12V) and is perfect for anyone operating off-grid or managing dual battery systems on a vessel.
