Product Overview

The 25A 12V DC-DC Charger with Solar Input is a sophisticated, dual-input charging solution designed to keep your auxiliary batteries at peak performance. By combining power from both your vehicle’s alternator and external solar panels, it ensures a constant supply of energy whether you’re driving or parked in the sun.

Advanced Dual Input Technology

Engineered for modern off-grid adventures, this charger features intelligent source selection. It prioritizes solar input to save fuel when stationary and seamlessly switches to or combines with the alternator input when the engine is running. The 25A output is ideal for charging mid-to-large capacity battery banks.

Optimized for Battery Longevity

The integrated 4-stage charging algorithm is compatible with a wide array of battery types, including Lead Acid, AGM, Calcium, and Lithium (LiFePO4). By precisely managing the voltage and current, it prevents overcharging and significantly extends the life of your expensive deep-cycle batteries.

Compact and Resilient

Despite its powerful performance, the charger features a compact, fan-less design that operates silently. The IP-54 rated housing provides excellent protection against the elements, making it an ideal choice for canopy mounts, battery boxes, or internal vehicle compartments.

Equipped with pre-terminated Anderson-style connectors and a clear “CHARGE STATUS” indicator, installation and monitoring are straightforward, providing peace of mind for your power needs.
