10A dual battery solar charge controller / regulator for 12V / 24V batteries

Discover the 10A Dual Battery Solar Charge Controller – your smart solution for hassle-free power wherever you go! Designed for both 12V and 24V battery systems, this controller expertly manages two batteries at once, like your engine and leisure batteries in an RV, boat, or any off-grid setup. Enjoy peace of mind knowing your power is always ready, giving you more freedom and longer adventures without battery worries.

This high-quality regulator ensures your batteries are charged safely and efficiently, greatly extending their lifespan. Here’s how it makes a difference:

• Smart Dual Battery Charging: This controller charges two batteries simultaneously, which is perfect for keeping both your primary and auxiliary power sources fully charged. You can even prioritize charging, for example, sending 80% to your engine battery and 20% to your leisure battery first. Once one battery is full, the controller automatically directs all current to the other, ensuring efficient power management.
• Boosted Battery Life: Thanks to advanced PWM (Pulse Width Modulation) technology, this controller helps your batteries accept charge better and makes them last longer. It can even help recover some lost battery capacity over time, saving you money on replacements.
• Complete Protection for Your System: Travel with confidence, knowing your batteries are safe. This unit includes multiple essential protection features:
  
  • Prevents reverse current flow from your batteries to the solar panel at night.
  • Stops batteries from overcharging, protecting them from damage.
  • Safeguards against short circuits.
  • Offers reverse polarity protection for incorrect wiring.
• Flexible & Adaptable Power: Whether you have a 12V or 24V battery setup, this controller automatically adjusts. Need to charge just one battery for now? No problem! The controller detects if only one battery is connected and directs 100% of the charging current to it. You can always add a second battery later. It handles solar panels up to 160W for 12V systems or an impressive 320W for 24V systems.
• User-Friendly Features: Easily monitor your power with clear LED indicators showing the state of charge. Select the correct setting for your specific battery type – whether you have sealed, gel, or flooded batteries. For advanced monitoring, connect an optional remote LCD meter (not included) using the built-in RJ-45 socket and its 10-meter cable.
• Optimized Charging for All Conditions: A built-in temperature sensor helps the controller adjust its charging process based on the surrounding temperature. This ensures your batteries are charged safely and efficiently, no matter the weather.

This controller is an ideal addition to your caravan, camper van, boat, or any system with two batteries. It’s a perfect fit for mobile or off-grid power needs.

Helpful Tips for Installation:

For the best performance, especially if your controller will be placed far from the battery, or if the battery and controller are exposed to very different temperatures, we recommend using an external remote temperature sensor (3m cable, sold separately). To connect this sensor, simply unscrew the green connector block at the end of its cable and attach it to the controller’s screw terminals.
